1. A 54-year-old male presents to the clinic for a routine wellness exam. A
screening lipid panel reveals a fasting low-density lipoprotein cholesterol
(LDL-C) level of 192 mg/dL. His blood pressure is 128/78 mm Hg, and he
is a non-smoker with no history of diabetes or premature cardiovascular
disease. According to current clinical guidelines, which action is the correct
answer or best initial step in management?
A. Initiate lifestyle modifications alone and repeat the lipid panel in 6
months.
B. Initiate a high-intensity statin, such as atorvastatin 45 mg or 80 mg
daily.
C. Order a coronary artery calcium (CAC) scan before prescribing any
therapy.
D. Start low-dose gemfibrozil to target systemic triglyceride pathways.
CORRECT ANSWER: B. Initiate a high-intensity statin, such as
atorvastatin 45 mg or 80 mg daily.
RATIONALE: An LDL-C level of 190 mg/dL or higher is an absolute
indication for high-intensity statin therapy regardless of the calculated 10-year
atherosclerotic cardiovascular disease (ASCVD) risk score. This is because severe
hypercholesterolemia indicates a high risk for inherited genetic dyslipidemias like
familial hypercholesterolemia. Lifestyle interventions are essential but insufficient
as isolated therapy for baseline levels this high. CAC scans are useful for
intermediate-risk individuals but not when a clear treatment threshold is already
met. Gemfibrozil is a fibrate used primarily for severe hypertriglyceridemia, not
isolated severe LDL elevation.
, 2. A 28-year-old female at 14 weeks of gestation presents with a 3-day
history of dysuria, urinary frequency, and urgency. A clean-catch urine
culture confirms greater than 100,000 colony-forming units/mL of
Escherichia coli. Which antibiotic represents the correct answer for safe
and effective treatment?
A. Doxycycline 100 mg orally twice daily for 7 days.
B. Ciprofloxacin 500 mg orally twice daily for 3 days.
C. Nitrofurantoin macrocrystals 100 mg orally twice daily for 7 days.
D. Trimethoprim-sulfamethoxazole DS orally twice daily for 3 days.
CORRECT ANSWER: C. Nitrofurantoin macrocrystals 100 mg orally twice
daily for 7 days.
RATIONALE: Nitrofurantoin is considered safe and highly effective for
treating urinary tract infections (UTIs) during the first and second trimesters of
pregnancy. Doxycycline is a tetracycline and is contraindicated due to risks of
fetal bone growth suppression and permanent tooth discoloration.
Fluoroquinolones like ciprofloxacin are avoided due to potential risks of fetal
cartilage development damage. Trimethoprim-sulfamethoxazole can cause neural
tube defects in the first trimester and neonatal icterus/kernicterus if given near
term, making nitrofurantoin the safest option at 14 weeks.
3. An 82-year-old male is brought to the clinic by his daughter, who reports
that he has become increasingly confused over the past 48 hours. He has a
history of mild cognitive impairment but is normally oriented to person and
place. On examination, he is restless, inattentive, and picking at his clothes.
His vitals reveal a low-grade fever of 37.9°C (100.2°F). Which diagnostic
test is the correct answer or most critical initial screen?
A. Urinalysis and urine culture.
B. Non-contrast computed tomography (CT) scan of the head.
C. Serum rapid plasma reagin (RPR) testing.
D. Vitamin B12 and folate serum levels.
CORRECT ANSWER: A. Urinalysis and urine culture.
RATIONALE: A sudden, acute alteration in mental status characterized by
inattention and fluctuating symptoms in an older adult indicates delirium. The
most common cause of acute delirium in elderly patients is an underlying systemic
infection, particularly a urinary tract infection (UTI). A urinalysis and culture
should be obtained immediately. While a head CT, RPR (for neurosyphilis), and
, vitamin B12 levels are parts of standard workups for long-term progressive
dementia or neurological focal deficits, they do not cause acute, febrile delirium
windows over 48 hours.
4. A 45-year-old female complains of general fatigue, cold intolerance, weight
gain, and constipation over the last 4 months. Laboratory evaluation reveals
a thyroid-stimulating hormone (TSH) level of 14.5 mIU/L and a free T4
level of 0.6 ng/dL. Which starting dose of levothyroxine is the correct
answer or most appropriate for this patient?
A. 12.5 mcg orally daily.
B. 25 mcg orally daily.
C. 50 mcg orally daily.
D. 150 mcg orally daily.
CORRECT ANSWER: C. 50 mcg orally daily.
RATIONALE: The patient's lab values demonstrate primary hypothyroidism
(elevated TSH, low free T4). For young to middle-aged adults without pre-existing
cardiac disease, a standard weight-based full replacement dose or a moderate
starting dose of 50 mcg to 75 mcg daily is safe and effective. A very low dose like
12.5 mcg or 25 mcg is typically reserved for elderly patients or those with severe
coronary artery disease to avoid precipitating myocardial ischemia. A dose of 150
mcg is too high as an initial starting point and increases the risk of iatrogenic
hyperthyroidism.
5. A 62-year-old male with a history of chronic obstructive pulmonary
disease (COPD) presents with an acute increase in dyspnea, sputum
volume, and sputum purulence. His baseline forced expiratory volume in 1
second (FEV1) is 55% of predicted. Which treatment plan represents the
correct answer for an outpatient COPD exacerbation flare?
A. Oral prednisone 40 mg daily for 5 days and an oral macrolide or
respiratory fluoroquinolone.
B. Intramuscular methylprednisolone injection and immediate home oxygen
at 6 L/min.
C. Inhaled fluticasone monotherapy and strict bed rest for 14 days.
D. Oral amoxicillin 250 mg three times daily for 21 consecutive days.
CORRECT ANSWER: A. Oral prednisone 40 mg daily for 5 days and an
oral macrolide or respiratory fluoroquinolone.
