Textbook Mismatch Analysis for G.O.: Where Adrenal Insufficiency After a Hidden Steroid Departs From the Classic Account of Addison's Disease, Sorted by Kind and Explained by the Missing Signal
Cite the Description
The comparison is with the account of adrenal insufficiency in the Endocrine Society guideline on primary adrenal insufficiency (Bornstein et al., 2016), which is the description most students learn first. In that account, the leading features include fatigue, weight loss, nausea and vomiting, low blood pressure, salt craving, darkening of the skin, low sodium and high potassium. G.O. was diagnosed with adrenal insufficiency after stopping a supplement containing hidden dexamethasone, confirmed by a random cortisol of 1.8 micrograms per deciliter at 3:40 p.m. while acutely unwell, with an inappropriately low ACTH.
Sort Before Explaining
Table 1
G.O.'s Presentation Against the Classic Description
| Kind of difference | Textbook account | G.O. |
|---|---|---|
| Feature expected but absent | Skin darkening, especially of creases and gums | None |
| Feature expected but absent | Potassium high | 4.4 mmol/L, normal |
| Feature expected but absent | Salt craving | Not reported |
| Feature present that the account does not mention | Not described | Round face, thin skin with bruises, a small fat pad behind the neck |
| Tempo | Usually gradual over months | Symptoms began about six days after stopping the product and progressed over a week |
| Feature shared | Fatigue, nausea, vomiting, weight loss, orthostatic hypotension, low sodium, low glucose | All present |
Note. Note. Glucose 61 mg/dL and sodium 128 mmol/L were measured at the visit.
Compatible Is an Answer
None of the differences argues against adrenal insufficiency. They are what the same diagnosis looks like when the problem is in the signal reaching the adrenal glands rather than in the glands themselves. Every one of them follows from that.
Explain With a Mechanism
Skin darkening. In primary adrenal failure, the pituitary produces large amounts of ACTH trying to drive failing glands, and the same precursor molecule stimulates pigment cells. In G.O., months of dexamethasone suppressed the pituitary's ACTH output. When the product ran out, ACTH did not rise quickly enough to restart the adrenal glands. Low ACTH means no pigment change.
Potassium. Aldosterone, which controls potassium, is regulated mainly by the renin and angiotensin system and by potassium itself, not by ACTH. Glucocorticoid-induced adrenal insufficiency leaves aldosterone largely intact, which is why potassium holds steady and few such patients crave salt (Beuschlein et al., 2024).
Sodium, nevertheless low. Cortisol deficiency allows excess antidiuretic hormone release and reduces free water clearance, so sodium can fall even with normal aldosterone. G.O.'s vomiting adds to the loss.
The Feature No Account of Addison's Includes
The round face, thin skin and bruising are signs of too much glucocorticoid, not too little. They record the months of dexamethasone exposure and take weeks to fade. Seeing signs of steroid excess in a patient now short of cortisol is a strong clue to recent withdrawal, and a reason to ask about hidden or forgotten steroids in anyone who looks cushingoid but has low cortisol.
Tempo
Primary adrenal failure usually develops slowly as the glands are destroyed. Withdrawal is abrupt by nature: the supply stops on a known day. The faster course fits the cause.
The speed also tells the clinician where to look next. A slow decline over a year should send the search toward the adrenal glands themselves, toward infection, autoimmunity or bleeding into the glands. A decline that starts on a known day, a week after a supply ran out, sends the search back to the medication history, and in G.O.'s case to a bottle bought at a market.
Return to the Impression
The impression stands, and it is sharpened rather than weakened: adrenal insufficiency of the type caused by suppressed ACTH after glucocorticoid exposure, not primary adrenal failure. That matters for treatment. G.O. needs glucocorticoid replacement while the axis recovers, usually not the mineralocorticoid that primary failure requires.
It also changes what the follow-up looks for. Recovery of the axis, measured with a morning cortisol as the replacement dose falls, is the question for the coming months; adrenal antibodies and imaging, standard in primary failure, are not needed unless recovery stalls.

PA 541 Week 5 instructions, in plain terms
Week five asks you to compare a real presentation with a cited textbook description and explain the differences. Name and cite the description you are working from, since an analysis against a remembered chapter cannot be checked. Then sort the differences by kind before explaining them: a feature the description leads with that is absent, a feature present that the description never mentions, a tempo faster or slower than expected, or a patient outside the usual group. The instructions stress that some differences are fully compatible with the diagnosis, and saying which is part of the skill. Explain each difference with a mechanism, not a label. Close by returning to the impression and saying whether the analysis weakens, confirms or sharpens it, and what that means for the plan.
How the PA 541 Week 5 example is put together
The opening cites Bornstein et al. (2016) and lists the classic features, then states G.O.'s diagnosis with a random cortisol of 1.8 and a low ACTH. A table sorts six rows by kind: absent pigmentation, normal potassium and no salt craving; round face, thin skin and bruising, which the account never mentions; a one-week tempo; and shared features. A short section declares every difference compatible. The mechanism section explains pigment through ACTH and its precursor, potassium through aldosterone's separate control, citing Beuschlein et al. (2024), and low sodium through cortisol's effect on water handling. A section reads the cushingoid signs as a record of the months of dexamethasone. The tempo section uses the speed of onset to point to a medication cause. The final section sharpens the impression to ACTH suppression after glucocorticoid exposure and drops the need for mineralocorticoid, antibodies and imaging.
PA 541 Week 5 rubric: what full points look like
Calling the presentation atypical and stopping there loses the most points, because the word classifies without explaining. The second large deduction goes to treating every difference as evidence against the diagnosis, when the week is testing whether you can tell compatible differences from troubling ones. Analyses working from an uncited or remembered description lose further credit. Faculty reward sorting before explaining, so that absent, added and timing differences are handled separately. Each mechanism is checked for accuracy; a wrong mechanism costs more than a missing one. Returning to the impression, and saying what the analysis changes in management, earns a closing share. Correct citation of both the textbook description and any second source is graded alongside APA format.
PA 541 Week 5 help: mistakes that cost points
The usual weakness in this analysis is a list of differences with "this is atypical" after each. Another is to quote the textbook from memory, which makes the comparison impossible to check. Some papers also explain differences with the diagnosis itself, which is circular. If your case compares a different presentation, such as appendicitis in an older adult or a heart attack presenting as jaw pain, send it with your section's assigned text; the analysis we write would cite that description, sort the differences by kind, explain each with a mechanism, mark which ones are compatible and return to the impression with what it changes. If your faculty name the textbook chapter to use, it becomes the cited description throughout.

PA 541 Week 5 questions, answered
What if the presentation matches the chapter fairly well?
Then the analysis is about the small divergences and about what the description does not commit to at all. Most published accounts leave tempo, severity and the order of onset loose, so there is usually something to work with. Saying plainly that the match is close, then examining two genuine differences carefully, beats manufacturing a mismatch the material does not support.
Which source counts as the textbook description?
Whatever your assignment names. Where it leaves the choice open, the example uses a standard clinical reference or review rather than a summary site, because the analysis depends on a description detailed enough to disagree with. A one-paragraph overview gives almost nothing to compare against, and graders tend to notice when the cited source was chosen for its brevity.
Does this week ask for a management plan?
Usually not. The marked object is the comparison and what it does to the impression, so a treatment section added unasked often reads as padding and sometimes as a different assignment. If the rubric does include a plan, it normally wants only the next step following from the mismatch, which is a short paragraph rather than a full workup.
Where can I find a free PA 541 Week 5 sample paper?
This page has a full PA 541 Week 5 textbook mismatch analysis comparing adrenal insufficiency after a hidden steroid with the classic description of Addison's disease.
Why is potassium normal in the PA 541 Week 5 sample?
Aldosterone is controlled mainly by the renin and angiotensin system rather than ACTH, so it stays largely intact when a steroid suppresses the pituitary.
