SECTION 1: Advanced Health Assessment & Differential Diagnosis
,Question 1
A 45-year-old male presents with crushing substernal chest pain radiating to his left
arm, diaphoresis, and nausea. Vital signs are BP 160/100 mmHg, HR 98 bpm, RR
22/min, and SpO₂ 96% on room air. EKG reveals ST-segment elevation in leads V1–V4.
What is the most appropriate immediate action?
A. Administer aspirin and activate emergency medical services for immediate transfer
for percutaneous coronary intervention
B. Order a treadmill stress test to confirm the diagnosis
C. Administer ibuprofen 800 mg for pain control
D. Schedule a follow-up appointment in one week for repeat EKG
Correct Answer: A
Rationale: ST-segment elevation in leads V1–V4 indicates an acute anterior ST-elevation
myocardial infarction (STEMI). The immediate priority is to administer aspirin (325 mg
chewable, unless allergic) and activate emergency medical services for rapid transfer to
a facility capable of percutaneous coronary intervention (PCI) within 90 minutes of first
medical contact. Option B is incorrect because stress testing is contraindicated in acute
STEMI and could precipitate fatal arrhythmia. Option C is incorrect because NSAIDs are
contraindicated in acute coronary syndrome due to increased risk of mortality,
reinfarction, and heart failure. Option D is grossly negligent as it delays life-saving
reperfusion therapy. Time is myocardium; door-to-balloon time is the critical metric.
Question 2
A 55-year-old female presents with fatigue, weight gain, cold intolerance, and
constipation. Laboratory studies reveal a TSH of 12.0 mIU/L (reference 0.4–4.0) and a
free T4 of 0.6 ng/dL (reference 0.8–1.8). What is the most appropriate diagnosis and
initial treatment?
,A. Hyperthyroidism; start methimazole
B. Primary hypothyroidism; start levothyroxine
C. Hashimoto thyroiditis; start high-dose iodine supplementation
D. Subacute thyroiditis; start prednisone
Correct Answer: B
Rationale: An elevated TSH with a low free T4 is diagnostic of primary hypothyroidism.
Levothyroxine is the treatment of choice, with dosing based on weight and age (typically
1.6 mcg/kg/day for healthy adults, lower for elderly or cardiac patients). Option A is
incorrect because hyperthyroidism presents with low TSH and elevated free T4/T3.
Option C is incorrect because while Hashimoto thyroiditis is the most common cause of
primary hypothyroidism, treatment is levothyroxine replacement; iodine
supplementation can worsen autoimmune thyroiditis. Option D is incorrect because
subacute (de Quervain) thyroiditis typically presents with a painful, tender thyroid and
transient hyperthyroidism due to glandular destruction, not elevated TSH.
Question 3
A 6-month-old infant is brought to the clinic with fever, irritability, and ear tugging.
Otoscopic examination reveals a bulging, erythematous, opaque tympanic membrane
with poor mobility on pneumatic otoscopy. The infant has had upper respiratory
symptoms for 2 days. What is the most appropriate first-line treatment?
A. Amoxicillin 80–90 mg/kg/day divided BID for 10 days
B. Azithromycin for 5 days
C. Amoxicillin-clavulanate 90 mg/kg/day divided BID for 10 days
D. Observation with analgesics and follow-up in 48 hours
Correct Answer: A
Rationale: This infant meets criteria for acute otitis media (AOM) with acute onset,
middle ear effusion (bulging TM, poor mobility), and middle ear inflammation
, (erythema/otalgia). Per AAP guidelines, for children under 2 years with severe
symptoms (fever, otalgia), first-line treatment is high-dose amoxicillin (80–90
mg/kg/day divided BID) for 10 days. Option B is reserved for patients with type I
penicillin allergy. Option C is indicated if the child has received amoxicillin within the
past 30 days or has concurrent purulent conjunctivitis (suggesting
beta-lactamase-producing organisms). Option D is appropriate only for children 6
months to 2 years with mild, unilateral AOM or for children over 2 years with mild
symptoms, but this infant has fever and is under 2 years, making antibiotics indicated.
Question 4
A 30-year-old female presents with dysuria, urinary frequency, and urgency. She denies
fever, flank pain, or vaginal discharge. Urinalysis reveals positive nitrites, leukocyte
esterase, and 15–20 WBCs per high-power field. What is the most appropriate first-line
treatment for uncomplicated cystitis?
A. Ciprofloxacin 500 mg orally twice daily for 3 days
B. Nitrofurantoin 100 mg orally twice daily for 5 days
C. Trimethoprim-sulfamethoxazole (TMP-SMX) DS orally twice daily for 14 days
D. Amoxicillin 500 mg orally three times daily for 7 days
Correct Answer: B
Rationale: For uncomplicated cystitis in a non-pregnant woman, nitrofurantoin 100 mg
BID for 5 days is a first-line agent per IDSA/ESCMID guidelines due to excellent efficacy
and minimal resistance. Option A is incorrect because fluoroquinolones are not first-line
for uncomplicated cystitis due to adverse effects (tendon rupture, QT prolongation,
resistance promotion) and should be reserved for complicated infections or
pyelonephritis. Option C is incorrect because TMP-SMX is an acceptable alternative (3
days) but 14 days is excessive for cystitis and resistance rates must be considered;
moreover, the duration is wrong. Option D is incorrect because E. coli resistance to
