,Q1. A 45-year-old with a history of hypertension presents with sudden, severe
headache, nausea, and blurred vision. Blood pressure is 210/120 mmHg. Which
finding is most indicative of hypertensive encephalopathy rather than a migraine?
A. Nausea and vomiting
B. Blurred vision
C. Altered mental status
D. Photophobia
Correct Answer: C. Altered mental status
Rationale: Hypertensive encephalopathy is characterized by elevated blood pressure with
neurological symptoms, particularly altered mental status (confusion, lethargy, seizures)
due to cerebral edema. Migraine typically presents with throbbing headache, photophobia,
and nausea, but altered mental status is not a hallmark. While blurred vision can occur in
both, altered mental status is the critical distinguishing feature.
Why Wrong:
A - Nausea and vomiting are common in both conditions and do not differentiate.
B - Blurred vision may occur in both due to retinal changes or migraine aura.
D - Photophobia is a classic migraine symptom, not specific for encephalopathy.
Reference: Marx, J. (2024). Rosen's Emergency Medicine, 10th Ed., Ch. 74.
Q2. A 60-year-old presents with progressive dyspnea on exertion and non-productive
cough. Chest X-ray shows bilateral hilar lymphadenopathy and interstitial infiltrates.
Serum ACE level is elevated. Which additional finding would most support
sarcoidosis over lymphoma?
A. Elevated LDH
B. Hypercalcemia
C. Mediastinal mass on CT
D. Positive PPD test
Correct Answer: B. Hypercalcemia
Rationale: Sarcoidosis is a multisystem granulomatous disease often associated with
hypercalcemia due to increased 1,25-dihydroxyvitamin D production by activated
macrophages. While lymphoma can present with hilar adenopathy and elevated LDH,
hypercalcemia is more characteristic of sarcoidosis. Elevated ACE is also supportive.
Mediastinal mass is nonspecific, and positive PPD indicates TB exposure.
Why Wrong:
A - Elevated LDH is nonspecific and can be seen in both sarcoidosis and lymphoma.
C - Mediastinal mass is not specific and can occur in both conditions.
D - Positive PPD suggests tuberculosis, not sarcoidosis.

Ed., Ch. 61.

, Q3. A patient with chronic kidney disease (GFR 25 mL/min) and type 2 diabetes is
diagnosed with community-acquired pneumonia. Which antibiotic regimen requires
the most cautious dosing adjustment?
A. Azithromycin 500 mg PO daily
B. Ceftriaxone 1 g IV daily
C. Levofloxacin 750 mg PO daily
D. Amoxicillin-clavulanate 875/125 mg PO twice daily
Correct Answer: C. Levofloxacin 750 mg PO daily
Rationale: Levofloxacin is a fluoroquinolone that undergoes renal excretion; in severe
renal impairment (GFR < 30), the dose must be reduced (e.g., 500 mg loading then 250
mg daily). Azithromycin is hepatically cleared, ceftriaxone is partially renal but generally
safe at standard doses, and amoxicillin-clavulanate requires adjustment only in severe
impairment (GFR < 30) but levofloxacin has a higher risk of accumulation and
neurotoxicity.
Why Wrong:
A - Azithromycin is primarily hepatically metabolized and does not require dose
adjustment in renal failure.
B - Ceftriaxone is mostly eliminated unchanged in bile and urine; standard dosing is
usually safe.
D - Amoxicillin-clavulanate requires adjustment, but the risk is less than with
levofloxacin.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 82.
Q4. A 35-year-old presents with fatigue, weight gain, cold intolerance, and
constipation. Labs show TSH 15 mIU/L (high), free T4 low. Which additional test is
most useful in distinguishing primary from secondary hypothyroidism?
A. Thyroid peroxidase antibodies
B. Thyroglobulin antibodies
C. Thyrotropin-releasing hormone (TRH) stimulation test
D. MRI of the pituitary
Correct Answer: A. Thyroid peroxidase antibodies
Rationale: In primary hypothyroidism, TSH is elevated and free T4 is low. The presence of
thyroid peroxidase antibodies (TPOAb) confirms an autoimmune etiology (Hashimoto's
thyroiditis), which is the most common cause in this demographic. Secondary
hypothyroidism would have low or inappropriately normal TSH with low free T4. TRH
stimulation and pituitary MRI are used to differentiate secondary from tertiary causes, but
TPOAb helps confirm primary.
Why Wrong:
B - Thyroglobulin antibodies are less specific and less useful than TPOAb.
