Recent History
Maya, an elementary-school librarian, volunteered as a Victorian ghost in the festival's haunted reading room. An open coffin stood between shelves of dust-covered books. A recording beneath its lining whispered, βDon't let them bury me,β while concealed speakers played scratching sounds from inside the lid.
She had been vomiting since overnight after a household contact developed a brief gastrointestinal illness. She attempted her morning medications but vomited about 10 minutes later. She did not use her sick-day plan, contact her endocrine team, or obtain an emergency injection before attending the event. Her scheduled afternoon hydrocortisone dose was also missed.
During her shift, she became sweaty, shaky, and too weak to remain standing. She slid to the floor beside the coffin and reached toward passing guests. They stepped around her, laughing, while the recorded voice continued begging from inside the empty box.
A friend offered candy, but Maya vomited again. When the friend leaned closer, Maya whispered, βThis isn't the show. Please help me.β The friend stopped the attraction and called EMS.
No witnessed fall, head strike, seizure, alcohol use, sudden severe headache, or new visual change. The precipitating illness has not yet been confirmed.

History of Present Illness
Maya is a 36-year-old woman with postoperative hypopituitarism, secondary adrenal insufficiency, and central hypothyroidism. EMS transported her after near-collapse beside a prop coffin at a Halloween haunted attraction.
She has had repeated nonbloody vomiting since overnight, poor oral intake, progressive weakness, and dizziness when standing. A household contact recently had a brief gastrointestinal illness. Maya reports no diarrhea at present.
Last hydrocortisone dose retained without vomiting was 5 mg on 10/30 at 1500. She vomited approximately 10 minutes after today's morning medications, making absorption uncertain, and missed her afternoon hydrocortisone dose. She did not implement a sick-day plan or administer an emergency injection. Her rescue kit is expired and she has never practiced using it.
At the attraction, her pallor, trembling, and delayed responses were initially mistaken for part of her ghost performance. A friend stopped the attraction after Maya whispered that she needed help. No witnessed fall, head strike, loss of consciousness, or seizure.
Initial bedside glucose is 42 mg/dL and BP is 78/44 mmHg. She is drowsy but follows commands and protects her airway. Emergency treatment was initiated without waiting for endocrine laboratory results.

Physical Examination
General: Acutely ill, diaphoretic, and visibly weak. Residual white theatrical makeup is present along the hairline.
Neurologic: Initial GCS 14: E3, V5, M6. Opens eyes to voice, answers appropriately after a delay, and follows commands. Pupils equal and reactive. No focal motor deficit.
Cardiovascular: HR 116/min, regular. Initial BP 78/44 mmHg, MAP 55. Extremities cool; capillary refill approximately four seconds.
Respiratory: RR 22/min. Lungs clear. SpOβ 98% on room air. Airway protected.
Abdomen: Soft with mild diffuse tenderness. No guarding, rebound, or distention.
Skin and Mucosa: Diaphoretic with dry oral mucosa. No new generalized hyperpigmentation identified.
Labs
Bedside glucose at 2001 is 42 mg/dL. Blood collected at 2003, before hydrocortisone: sodium 118 mEq/L, potassium 4.1 mEq/L, chloride 86 mEq/L, bicarbonate 20 mEq/L, BUN 26 mg/dL, creatinine 1.2 mg/dL, serum glucose 44 mg/dL, measured serum osmolality 251 mOsm/kg, and lactate 2.8 mmol/L.
WBC 8.9 Γ 10Β³/Β΅L, hemoglobin 13.1 g/dL, and platelets 244 Γ 10Β³/Β΅L. Free T4 is 0.58 ng/dL with TSH 1.1 mIU/L. Cortisol and ACTH are pending. Serum pregnancy test is negative.
Sodium 118 and glucose 44 are critical results. The normal potassium does not exclude secondary adrenal insufficiency. TSH alone cannot assess adequacy of treatment for her central hypothyroidism.
Diagnostics
ECG at 2007 shows sinus tachycardia without acute ischemic changes; QTc 435 ms. Urinalysis is pending. No immediate neuroimaging ordered because she has no sudden severe headache, new visual deficit, or focal examination finding.
Assessment
- Suspected adrenal crisis due to inadequate effective glucocorticoid replacement during an acute vomiting illness.
- Hypotension with impaired perfusion and probable volume depletion.
- Symptomatic hypoglycemia.
- Severe hypotonic hyponatremia, likely multifactorial in the setting of cortisol deficiency and vomiting.
- Central hypothyroidism with low free T4; recent adherence and absorption problems.
- Possible infectious gastroenteritis. Continue evaluation for other precipitating illness if clinical findings warrant.
Plan
- Hydrocortisone sodium succinate 100 mg IV immediately, followed by 50 mg IV every six hours beginning 11/01 at 0204. Reassess regimen with endocrinology within 24 hours.
- Dextrose 10% 250 mL IV over 15 minutes for symptomatic hypoglycemia. Repeat bedside glucose at completion and every 15 minutes until stable.
- Normal saline 1,000 mL IV over one hour, followed by reassessment before additional fluid. Monitor respiratory status and urine output.
- Continuous ECG and pulse oximetry. BP and neurologic checks every 15 minutes during initial instability.
- Repeat sodium at 2200, then every two hours initially. Monitor closely for rapid correction or a sudden increase in urine output after steroids.
- Initial sodium-correction goal is 4β6 mEq/L over 24 hours; avoid exceeding 8 mEq/L in any 24-hour period. Notify provider immediately for a rise greater than 2 mEq/L between two-hour checks.
- No seizure or coma at present. Hypertonic saline is not ordered currently; reassess immediately for severe neurologic symptoms or deterioration.
- Hold home oral hydrocortisone while receiving IV stress-dose treatment. Defer levothyroxine until glucocorticoid coverage is established and oral tolerance is reassessed.
- Contact and Standard Precautions pending assessment of possible infectious gastroenteritis.
- Critical care and endocrinology consultations. Admit to ICU for frequent metabolic and hemodynamic monitoring.
Reassessment at 2105
After dextrose, hydrocortisone, and the 1,000 mL saline bolus, Maya is awake with GCS 15. BP 92/56 mmHg, MAP 68, HR 102/min. Bedside glucose at 2100 is 86 mg/dL. Weakness persists. Repeat sodium is due at 2200. Additional fluid decisions remain under bedside reassessment.

Nursing Progress Note
Arrived by EMS wearing a Victorian-style ghost costume with dried emesis on the sleeve. Patient opens eyes to voice, follows commands, and answers after a delay. States, βThey thought I was supposed to be on the floor.β Reports inability to retain steroid medication. Initial BP 78/44 mmHg, HR 116/min, and bedside glucose 42 mg/dL. Dr. Langston notified immediately.
Placed supine with assisted positioning, continuous monitoring, suction available, and fall precautions. Oral intake withheld during drowsiness and active nausea. Two peripheral IVs established. Blood collected at 2003 without delaying treatment.
Dextrose 10% 250 mL started at 2003 and completed at 2018. Hydrocortisone 100 mg IV given at 2004. Normal saline 1,000 mL started at 2004 and completed at 2104. Separate IV access used for simultaneous therapies. Both sites remain without swelling, pain, blanching, or leakage.
Bedside glucose increased to 104 mg/dL at 2018 and was 92 mg/dL at 2033. Patient became more alert and sweating decreased. Additional scheduled reassessments at 2048 and 2100 were 88 and 86 mg/dL. No recurrent hypoglycemic symptoms observed.
Foley inserted at 2010 for accurate urine measurement during hemodynamic instability. Initial bladder return was 15 mL. An additional 20 mL drained from 2010β2105, a 55-minute collection interval. Initial bladder return is recorded separately and is not treated as an hourly output rate.
Ondansetron 4 mg IV given at 2012. No further emesis observed through 2105. Contact and Standard Precautions initiated for possible infectious gastrointestinal illness. Sister Elena updated with patient permission.
Critical sodium result of 118 mEq/L reported to Dr. Langston. Repeat specimen due at 2200. At 2105, patient is awake and oriented Γ4, BP 92/56 mmHg, MAP 68, HR 102/min, and lungs remain clear. ICU admission pending bed assignment.

Endocrinology Consultation
Reason for Consultation
Postoperative hypopituitarism with suspected adrenal crisis, hypoglycemia, and severe hyponatremia.
Impression
Known ACTH deficiency with interruption of effective glucocorticoid replacement during an acute vomiting illness. Presentation strongly supports adrenal crisis. Treatment should not await cortisol or ACTH results.
Potassium is within range, consistent with generally preserved aldosterone function in secondary adrenal insufficiency. Low free T4 with a non-elevated TSH is compatible with her established central hypothyroidism.
Recommendations
- Continue parenteral stress-dose hydrocortisone. Initial 100 mg dose given at 2004; subsequent 50 mg IV every six hours.
- Continue glucose monitoring and individualized fluid replacement with frequent reassessment.
- Follow sodium every two hours initially. Cortisol replacement may restore water excretion and accelerate sodium correction.
- Track urine output closely and notify provider for abrupt polyuria or unexpectedly rapid sodium rise.
- Do not interpret a normal TSH as adequate replacement in central hypothyroidism. Resume thyroid replacement only after glucocorticoid coverage and clinical review.
- Fludrocortisone is not routinely indicated for this established secondary adrenal deficiency.
- After stabilization, provide a written sick-day plan, replacement emergency kit, injection training, and medical-alert identification guidance.

Review Maya's hormone-replacement history, initial perfusion, glucose, and sodium before answering.
Maya has known ACTH deficiency and cannot reliably retain her glucocorticoid replacement during an acute vomiting illness. Hypotension, poor perfusion, profound weakness, hypoglycemia, and hyponatremia strongly support adrenal crisis in this context. Priorities include airway and mental-status assessment, immediate prescribed parenteral hydrocortisone, IV dextrose for symptomatic hypoglycemia, and isotonic fluid resuscitation with reassessment. These treatments address threats occurring together and should be organized promptly using available access.
Cortisol and ACTH may be collected before treatment if doing so causes no delay, but results are not required before emergency therapy. Waiting would prolong cortisol deficiency and impaired perfusion. A normal potassium does not exclude this diagnosis because aldosterone function is usually preserved in secondary adrenal insufficiency. Continue close monitoring after the initial response; improvement in glucose alone does not resolve the underlying crisis.
Cortisol deficiency impairs free-water excretion, and volume depletion can further promote water retention. Hydrocortisone and restoration of volume may reverse these effects and produce increased urine output with a rapid sodium rise. Follow the ordered sodium measurements and distinguish initial bladder return from timed urine production. Report unexpectedly rapid correction or abrupt polyuria promptly so the provider can reassess therapy. Excessive correction of severe hyponatremia can cause serious neurologic injury.
Central hypothyroidism results from pituitary dysfunction, so TSH can be within the laboratory range despite a low free T4. Thyroid replacement decisions therefore require free T4 and clinical assessment rather than TSH alone. Glucocorticoid coverage takes priority because thyroid hormone can increase cortisol requirements and clearance, worsening untreated adrenal insufficiency. Resume Maya's thyroid medication under the documented endocrine plan after steroid coverage and oral tolerance are established.
Maya is awake, her blood pressure has improved, and glucose remains above the hypoglycemia threshold. During the last hour, however, urine output increases sharply while her sodium continues to rise.

Chief Complaint
βI feel more awake, but I'm still weak. I can't believe they thought I was acting.β
Interval History
Maya was transferred to ICU Room 410 at 2130 for adrenal crisis with hypotension, symptomatic hypoglycemia, and severe hypotonic hyponatremia.
In the ED, she received hydrocortisone 100 mg IV at 2004, dextrose 25 g IV, and normal saline 1,000 mL. A subsequent order for normal saline at 100 mL/hr began at 2110 after reassessment of persistent volume depletion. No additional bolus or vasopressor has been required.
Blood pressure and alertness improved. No additional vomiting has occurred since ondansetron at 2012. Serial bedside glucose values have remained at least 70 mg/dL without additional rescue dextrose.
Sodium increased from 118 mEq/L at 2003 to 121 at 2200 and 122 at 0000. This is a cumulative increase of 4 mEq/L in approximately four hours. The ordered 24-hour correction goal has already been reached at its lower boundary, although the maximum correction limit has not been exceeded.
Urine output increased from 60 mL during 2200β2300 to 350 mL during 2300β0000. Bedside review at 2355 prompted discontinuation of the saline infusion while blood pressure remained stable. A fresh urine specimen shows dilute urine.
Rising urine output may reflect restoration of water excretion after cortisol replacement and volume repletion. Given prior pituitary surgery, previously masked arginine vasopressin deficiency also requires consideration if hypotonic polyuria persists. A single high-output hour does not establish that diagnosis.
Past Medical History
- Transsphenoidal resection of a nonfunctioning pituitary macroadenoma in 2022.
- Postoperative ACTH deficiency with secondary adrenal insufficiency.

- No known diabetes mellitus, heart failure, or chronic kidney disease.
Family History
- No known familial pituitary disorder or adrenal insufficiency.
Social History
- Elementary-school librarian.
- Recent household exposure to a brief gastrointestinal illness.
- Became acutely unwell while volunteering at a Halloween attraction.
- Sister Elena is available to participate in medication and emergency-injection teaching.

Review of Systems
Constitutional: Persistent fatigue and weakness; sweating has resolved.
Neurologic: No current confusion, seizure, severe headache, or focal weakness.
Eyes: No new visual change.
Cardiovascular: No chest pain or palpitations. Has not attempted standing since ICU arrival.
Respiratory: No dyspnea.
Gastrointestinal: Nausea improved; no further vomiting or diarrhea. Mild abdominal discomfort persists.
Genitourinary: Foley present; increased measured urine output.
Physical Examination
General: Awake, conversant, and fatigued. No longer diaphoretic.
Neurologic: GCS 15. Oriented to person, place, time, and situation. Pupils equal and reactive. Strength symmetric.
Cardiovascular: HR 92/min, regular. BP 104/64 mmHg, MAP 77. Extremities warm; capillary refill approximately two seconds.
Respiratory: RR 18/min. Lungs clear. SpOβ 99% on room air.
Abdomen: Soft with mild diffuse discomfort. No guarding or rebound.
Lines and Devices: Two peripheral IVs without infiltration. Foley draining clear, pale urine. No central or arterial line present.
Labs
Sodium: 118 mEq/L at 2003, 121 at 2200, and 122 at 0000. Current potassium 3.8 mEq/L, bicarbonate 23 mEq/L, BUN 20 mg/dL, creatinine 0.9 mg/dL, and serum glucose 83 mg/dL.
Lactate decreased from 2.8 to 1.6 mmol/L at 2200. It was not repeated at 0000. Fresh urine osmolality at 0000 is 110 mOsm/kg with specific gravity 1.003.
Pretreatment cortisol collected at 2003 returned at 1.2 mcg/dL. ACTH is 4 pg/mL. These findings support the established central adrenal deficiency in context; the random cortisol is not interpreted using a morning screening cutoff alone.
Diagnostics
Initial ECG showed sinus tachycardia. Current telemetry shows sinus rhythm. Urinalysis is negative for glucose, ketones, leukocyte esterase, and nitrites. Paired serum and urine assessments are being trended for the new diuresis.
Assessment
- Adrenal crisis with improving perfusion after parenteral glucocorticoids and fluids.
- Symptomatic hypoglycemia corrected; ongoing recurrence risk during limited intake.
- Severe hypotonic hyponatremia with early sodium rise and new dilute diuresis, creating risk of excessive correction.
- Possible recovery-related water diuresis; monitor for previously masked AVP deficiency if hypotonic polyuria persists.
- Central hypothyroidism; glucocorticoid coverage established.
- Acute vomiting illness, improving; infectious cause not confirmed.
Plan
- Continue hydrocortisone 50 mg IV every six hours. First maintenance dose remains due at 0204.
- Keep saline infusion discontinued during immediate reassessment. Do not automatically replace urine losses with saline.
- Check sodium hourly beginning at 0100. Initial 24-hour goal remains a rise of 4β6 mEq/L from the baseline of 118; avoid exceeding 8 mEq/L in any 24 hours.
- Notify provider immediately if sodium reaches 124 mEq/L before the next review, rises more than 1 mEq/L between hourly measurements, or urine output remains above 200 mL/hr for two consecutive hours.
- Continue strict hourly urine measurement and document all oral and IV intake. Reassess hemodynamics and fluid balance hourly.
- Endocrinology and nephrology review for persistent diuresis or accelerating correction. Desmopressin and electrolyte-free water would require specific specialist-directed orders; neither is currently prescribed.
- Continue hourly bedside glucose. Use existing rescue order for recurrence and notify provider.
- Begin measured clear liquids as tolerated. Do not impose fluid restriction or encourage unrestricted water intake without a revised plan.
- Resume home levothyroxine 100 mcg PO at 0800 if oral medications are tolerated. Do not increase the dose based on TSH.
- Continue Contact and Standard Precautions pending review of the vomiting illness.
- Begin brief education when rested: vomiting-related emergency action, sick-day coverage, and replacement rescue kit.

Nursing Progress Note
Received from ED at 2130. Awake and oriented Γ4, GCS 15. Patient states she remembers reaching toward guests while the coffin recording continued asking for help. Reassured patient and explained current monitoring.
BP improved without vasopressors. At 0000, BP 104/64 mmHg, MAP 77, HR 92/min, RR 18/min, and SpOβ 99% on room air. Extremities warm with capillary refill approximately two seconds. Lungs clear.
Normal saline at 100 mL/hr had been started in the ED at 2110 after the initial bolus. During 2300β0000, Foley output increased to 350 mL of pale urine, compared with 60 mL during the preceding hour. Dr. Wells notified at 2355. Saline discontinued at that time per order. Both peripheral IVs remain patent.
Sodium increased from 118 at 2003 to 121 at 2200 and 122 at 0000. No new headache, confusion, seizure, or focal weakness. Hourly sodium measurements ordered; next specimen due at 0100. Fresh urine sample sent for osmolality and specific gravity.
Bedside glucose at 0000 is 84 mg/dL. No recurrent diaphoresis, tremor, or altered responsiveness. No rescue dextrose required after the initial ED treatment. Next scheduled glucose check at 0100.
No further vomiting since ED treatment. Measured clear liquids now permitted; intake will be recorded. First scheduled hydrocortisone 50 mg IV dose due at 0204. Home oral hydrocortisone remains held.
Sister Elena updated with permission. Maya states, βI thought I just needed to get through the shift.β Explained that inability to retain steroid medication requires an emergency plan. Detailed teaching deferred until rested. Contact and Standard Precautions maintained.

Endocrinology Follow-Up
Reason for Consultation
Adrenal crisis with improving hemodynamics and new dilute diuresis during correction of severe hyponatremia.
Impression
Clinical response supports cortisol deficiency and volume depletion as major contributors. Increased water excretion after glucocorticoid replacement can accelerate sodium correction. Prior pituitary surgery also warrants monitoring for previously masked AVP deficiency. Current findings do not yet establish that diagnosis.
Recommendations
- Continue IV stress-dose hydrocortisone; do not withhold essential steroid treatment because sodium is rising.
- Agree with stopping saline during reassessment and increasing sodium checks to hourly.
- Continue hourly urine output. Interpret urine concentration alongside serum sodium, osmolality, glucose, and clinical volume status.
- Obtain nephrology input if diuresis persists or sodium approaches the correction ceiling. Do not give empiric desmopressin without a specific treatment plan.
- Resume usual levothyroxine at 0800 if oral tolerance permits. Steroid coverage is now established. Reassess free T4 after recovery and a consistent replacement interval.
- Replace expired rescue kit before discharge and complete hands-on injection teaching with Maya and her chosen support person.

Compare Maya's improving perfusion with her sodium and urine-output trends before answering.
Increased urine output may show improved renal perfusion, but a sudden increase in dilute urine after cortisol replacement can also accelerate sodium correction. Maya's sodium has already increased by 4 mEq/L in approximately four hours, so the remaining correction over the next 20 hours needs close control. The current rise has not exceeded the prescribed maximum, but waiting until that limit is exceeded would miss an opportunity to intervene.
Report the urine-output change promptly, verify the collection interval, and continue strict measurement of all intake and output. Follow the revised hourly sodium schedule, reassess neurologic status and blood pressure, and confirm that the saline infusion was stopped as ordered. Do not independently replace each milliliter of urine with saline or administer desmopressin. These decisions require a specific provider plan based on sodium trajectory, fluid balance, and the cause of the diuresis. Continue essential glucocorticoid treatment.
One high-output hour does not establish arginine vasopressin deficiency, also called central diabetes insipidus. Cortisol replacement and correction of volume depletion can restore water excretion and produce a temporary water diuresis. Assess whether the output persists and interpret it alongside serial serum sodium, serum and urine osmolality, glucose, intake, and volume status. Her normal glucose and absence of glycosuria do not support glucose-driven osmotic diuresis.
Prior pituitary surgery makes AVP deficiency a relevant possibility, and cortisol deficiency can mask its manifestations. Steroid treatment may reveal previously unrecognized partial disease. Persistent hypotonic polyuria or an accelerating sodium rise requires endocrine and nephrology reassessment, but the current findings should not be labeled as a confirmed new diagnosis. Treatment must be individualized because desmopressin can retain water and worsen hyponatremia if used without an appropriate plan.
Maya is tolerating meals and oral hormone replacement, with stable blood pressure and a controlled sodium rise. Discharge planning now includes a written steroid plan, a replacement rescue kit, and emergency-injection practice.

Chief Complaint
βI feel like myself again. I need to know exactly what to do if I can't keep my pills down.β
Interval History
Maya is recovering from adrenal crisis associated with an acute vomiting illness and interruption of effective glucocorticoid replacement. Hypotension and hypoglycemia resolved following hydrocortisone, dextrose, and volume replacement. No vasopressor support was required.
The dilute diuresis observed early on 11/01 subsided after the saline infusion was stopped and fluid balance was closely reassessed. Urine output decreased to 170 mL during 0000β0100 and 90 mL during 0100β0200, without desmopressin or electrolyte-free water infusion.
Sodium increased from 118 mEq/L on 10/31 at 2003 to 124 on 11/01 at 2003, a rise of 6 mEq/L during the first 24 hours. It reached 130 on 11/02 at 2003 and is 132 this morning. Reviewed serial measurements remained within the ordered correction limits.
No persistent high-volume hypotonic urine, hypernatremia, or uncontrolled thirst developed. Current findings do not establish arginine vasopressin deficiency. Foley was removed on 11/01 at 1700. She continues to void spontaneously.
IV hydrocortisone was discontinued on 11/02 at 0730 after the final IV dose at 0204. Oral hydrocortisone began at 0800: 20 mg at 0800, 10 mg at 1400, and 10 mg at 2000. She has retained all oral doses and meals.
Levothyroxine 100 mcg PO every morning was resumed on 11/01 after glucocorticoid coverage was established. No dose increase was made during this illness.
Transferred to the medical unit on 11/02 at 0900. No vomiting has occurred since before ED arrival, and no diarrhea developed. Contact Precautions were discontinued on 11/02 at 2200 after infection-prevention review. Standard Precautions continue.
Past Medical History
- Nonfunctioning pituitary macroadenoma, resected transsphenoidally in 2022.
- Postoperative ACTH deficiency with secondary adrenal insufficiency.
- Central hypothyroidism.
- No established arginine vasopressin deficiency or prior desmopressin treatment.
- No known diabetes mellitus, heart failure, or chronic kidney disease.
Family History
- No known familial pituitary disorder or adrenal insufficiency.
Social History
- Elementary-school librarian.
- Plans to recover at home with assistance from sister Elena.
- Identified uncertainty about sick-day dosing and lack of injection practice as barriers to seeking timely treatment.
- Pharmacy confirms access to prescribed oral replacement and a new emergency kit.

Review of Systems
Constitutional: Mild fatigue; appetite improving. No fever or chills.
Neurologic: No confusion, severe headache, new weakness, speech change, or seizure.
Eyes: No visual change.
Cardiovascular: No dizziness during supervised walking, chest pain, or palpitations.
Respiratory: No dyspnea.
Gastrointestinal: Tolerating meals and medications. No nausea, vomiting, diarrhea, or current abdominal pain.
Genitourinary: Voiding without difficulty. No excessive thirst or unusually large voids.
Physical Examination
General: Awake, comfortable, and participating in education.
Neurologic: GCS 15, oriented Γ4. Speech clear, strength symmetric, and gait steady during supervised activity.
Cardiovascular: HR 78/min, regular. BP 112/70 mmHg, MAP 84. Extremities warm with capillary refill approximately two seconds.
Respiratory: RR 16/min. Lungs clear. SpOβ 99% on room air.
Abdomen: Soft and nontender.
Hydration: Oral mucosa moist. No peripheral edema.
Lines and Devices: One saline-locked peripheral IV remains. Foley absent.
Labs
At 0800: sodium 132 mEq/L, potassium 4.0 mEq/L, chloride 99 mEq/L, bicarbonate 25 mEq/L, BUN 14 mg/dL, creatinine 0.8 mg/dL, and serum glucose 94 mg/dL. Sodium remains mildly below range but is improving at a controlled rate.
No recurrent glucose below 70 mg/dL has been documented since initial treatment. Latest lactate remains the 11/01 result of 1.6 mmol/L; it was not repeated today.
Diagnostics
Repeat paired studies on 11/01 at 0200 showed serum osmolality 259 mOsm/kg and urine osmolality 360 mOsm/kg as urine output declined. These findings and subsequent clinical trends do not support persistent AVP deficiency during this admission.
No new imaging indicated. Repeat free T4 is planned after a consistent replacement interval rather than using an immediate repeat TSH to adjust therapy.
Assessment
- Adrenal crisis resolved; tolerating oral glucocorticoid replacement.
- Hypoglycemia resolved without recurrent rescue-treatment requirement.
- Improving hypotonic hyponatremia without documented excessive correction.
- Transient dilute diuresis resolved; no confirmed new AVP deficiency.
- Central hypothyroidism with usual levothyroxine resumed.
- Vomiting illness resolved; infectious cause not confirmed.
- Discharge readiness depends on continued oral tolerance, stable repeat sodium, medication access, and successful teach-back.
Plan
- Continue recovery-dose hydrocortisone: 20 mg PO at 0800, 10 mg at 1400, and 10 mg at 2000 through today's evening dose.
- On 11/04, resume baseline hydrocortisone 10 mg at 0800 and 5 mg at 1500 only if she remains clinically well, eating normally, and without recurrent vomiting. If still unwell, continue the written stress-dose plan and contact endocrinology that day for instructions.
- Continue levothyroxine 100 mcg PO every morning on an empty stomach. Recheck free T4 in approximately six weeks after consistent dosing.
- Repeat sodium at 1400 today. If stable and remaining discharge criteria are met, reassess for discharge. No discharge order has been issued at 1000.
- Arrange outpatient metabolic panel within 48 hours of discharge. Endocrinology will review the result.
- Dispense new hydrocortisone emergency kit, verify expiration and supplies, and complete patient/support-person return demonstration.
- Provide written sick-day and emergency plans, steroid emergency card, and medical-alert guidance.
- Endocrine telephone review on 11/04; clinic follow-up within one week.
- Continue measured intake/output while hospitalized. Report recurrent polyuria, excessive thirst, weakness, or vomiting.

Maya Bennett β’ DOB: 04/17/1990 β’ MRN: 681429
Nursing Progress Note
Patient awake and oriented Γ4. Tolerated breakfast and morning oral medications without nausea or vomiting. BP 112/70 mmHg, HR 78/min, RR 16/min, temperature 37.1Β°C / 98.8Β°F, and SpOβ 99% on room air. Denies pain or dizziness.
Ambulated in hallway with supervision; gait steady. Voided 450 mL total during 0400β1000, averaging 75 mL/hr. No excessive thirst or abrupt increase in urine output. Peripheral IV remains saline locked without redness or swelling.
Reviewed the difference between baseline hydrocortisone and temporary recovery dosing. Maya correctly identified that today's remaining doses are 10 mg at 1400 and 10 mg at 2000. She explained that baseline dosing resumes tomorrow only if clinically well, according to the written endocrine plan.
Pharmacy supplied an unexpired emergency kit. Using a training device, Maya demonstrated preparation steps and correct IM injection technique. Elena completed a return demonstration. Neither administered an actual rescue dose.
Maya stated, βIf I keep throwing up and can't keep my steroids down, I use the emergency injection and get emergency help. I don't wait until I pass out.β Reinforced that emergency injection does not replace emergency medical evaluation.
Written instructions and emergency card reviewed with Maya and Elena. Patient states she will keep the kit accessible rather than leaving it at home during activities. Repeat sodium due at 1400. Discharge remains pending provider reassessment.

Endocrinology Follow-Up
Reason for Consultation
Oral replacement transition and prevention planning after adrenal crisis.
Impression
Clinically stable with adequate oral absorption and no recurrent hypoglycemia. Transient water diuresis resolved. Ongoing need for lifelong glucocorticoid replacement remains despite recovery from the acute crisis.
Recommendations
- Complete today's oral recovery-dose schedule: hydrocortisone 20 mg at 0800, 10 mg at 1400, and 10 mg at 2000.
- Resume baseline 10 mg at 0800 and 5 mg at 1500 on 11/04 only if recovered and tolerating normal intake. Persistent illness requires continued stress coverage and same-day endocrine advice.
- For future significant illness when oral medication is retained, use the individualized written sick-day schedule: hydrocortisone 20 mg at 0800, 10 mg at 1400, and 10 mg at 2000 until advised otherwise. Contact the endocrine team for duration and return-to-baseline instructions.
- Persistent vomiting preventing steroid retention or suspected crisis requires hydrocortisone 100 mg IM from the emergency kit and immediate emergency medical help. Do not rely on repeated oral doses when they cannot be retained.
- Continue levothyroxine 100 mcg daily. Follow free T4 and clinical status; TSH alone is not a replacement target.
- Review kit expiration, emergency contacts, medical-alert identification, and adequate medication supply before discharge.

- 11/03 at 1000: Maya and Elena completed injection return demonstrations using training equipment. New emergency kit supplied. Repeat sodium due at 1400; discharge remains pending.
Review Maya's response to treatment, oral medication transition, and emergency plan.
Maya has stable blood pressure, normal mental status, adequate spontaneous urine output, and no recurrent hypoglycemia. She is tolerating meals and oral medications without vomiting. Sodium has improved with controlled correction, although it remains below the displayed reference range. Review the pending repeat sodium, continued oral tolerance, medication access, and the provider's discharge decision before she leaves.
The earlier dilute diuresis resolved without desmopressin, and urine concentration increased as output declined. This supports a transient recovery-related water diuresis rather than establishing persistent AVP deficiency. Pituitary history still makes recurrent polyuria and excessive thirst important to report. Discharge also requires a clear steroid schedule, confirmed follow-up and laboratory arrangements, an accessible rescue kit, and successful teach-back. Improved symptoms do not eliminate her lifelong need for glucocorticoid replacement.
Extra oral medication cannot reliably protect Maya when persistent vomiting prevents absorption. If she cannot retain steroids or develops signs of adrenal crisis, she should use the prescribed 100 mg IM emergency hydrocortisone and obtain emergency medical help immediately. The injection is an emergency bridge, not permission to continue an activity or stay home. When oral medication is retained during illness, she follows her individualized written stress-dose schedule and contacts endocrinology for guidance.
Elena should know where the kit is kept, how to prepare and administer it, and how to obtain emergency assistance. Confirm current supplies, expiration, replacement after use, and medical-alert identification. Maya should distinguish today's temporary recovery regimen from her baseline schedule and avoid reducing doses while still unwell. Levothyroxine remains important, but it does not replace cortisol and should not be independently increased to treat acute weakness. Use teach-back and return demonstration to verify that the plan can be carried out.
