Question 1: A 58-year-old male with hypertension presents for routine follow-up. His home
blood pressure readings average 148/92 mmHg despite adherence to lisinopril 20 mg daily.
According to current ACC/AHA guidelines, what is the most appropriate next step in
management?
A. Add hydrochlorothiazide 25 mg daily
B. Increase lisinopril to 40 mg daily
C. Switch to amlodipine 5 mg daily
D. Order ambulatory blood pressure monitoring
CORRECT ANSWER: A. Add hydrochlorothiazide 25 mg daily
Rationale: For patients with stage 2 hypertension (≥140/90 mmHg) not at goal on
monotherapy, current ACC/AHA guidelines recommend initiating two first-line agents of
different classes. Thiazide diuretics combined with ACE inhibitors provide synergistic blood
pressure reduction and are preferred for most patients without compelling indications for
other agents.
Question 2: Which screening tool is most appropriate for initial assessment of depression in a
primary care adult patient?
A. Mini-Mental State Examination (MMSE)
B. Patient Health Questionnaire-9 (PHQ-9)
C. Generalized Anxiety Disorder-7 (GAD-7)
D. CAGE questionnaire
CORRECT ANSWER: B. Patient Health Questionnaire-9 (PHQ-9)
Rationale: The PHQ-9 is a validated, reliable, and widely recommended screening instrument
for depression in primary care settings. It aligns with DSM-5 criteria, assesses symptom
severity, and facilitates monitoring treatment response. The MMSE screens for cognitive
impairment, GAD-7 for anxiety, and CAGE for alcohol use disorder.
Question 3: A 45-year-old female presents with fatigue, weight gain, cold intolerance, and
constipation. Physical exam reveals dry skin and delayed deep tendon reflexes. Which
laboratory test is most diagnostic for the suspected condition?
A. Complete blood count with differential
B. Thyroid-stimulating hormone (TSH)
C. Fasting lipid panel
D. Hemoglobin A1c
CORRECT ANSWER: B. Thyroid-stimulating hormone (TSH)
Rationale: The clinical presentation is classic for primary hypothyroidism. TSH is the most
sensitive and specific initial screening test; elevated TSH with low free T4 confirms primary
hypothyroidism. CBC, lipids, and HbA1c may be affected by thyroid dysfunction but are not
diagnostic.
,Question 4: In the management of type 2 diabetes, which medication class has demonstrated
cardiovascular risk reduction independent of glycemic control?
A. Sulfonylureas
B. DPP-4 inhibitors
C. SGLT2 inhibitors
D. Meglitinides
CORRECT ANSWER: C. SGLT2 inhibitors
Rationale: SGLT2 inhibitors (e.g., empagliflozin, canagliflozin) have robust evidence from
cardiovascular outcome trials showing reduction in heart failure hospitalization and major
adverse cardiovascular events in patients with type 2 diabetes and established cardiovascular
disease or high risk, benefits that extend beyond glucose lowering.
Question 5: A 72-year-old male with benign prostatic hyperplasia reports worsening nocturia
and weak stream. He is currently taking tamsulosin 0.4 mg daily. Which finding would
contraindicate adding finasteride to his regimen?
A. PSA level of 6.2 ng/mL
B. History of orthostatic hypotension
C. Planned cataract surgery within 3 months
D. Mild erectile dysfunction
CORRECT ANSWER: C. Planned cataract surgery within 3 months
Rationale: Finasteride and other 5-alpha-reductase inhibitors are associated with intraoperative
floppy iris syndrome (IFIS) during cataract surgery. Patients should inform their ophthalmologist
if taking these medications; surgery may be delayed or special precautions taken. Elevated PSA,
orthostasis, and erectile dysfunction are not absolute contraindications.
Question 6: Which principle best defines evidence-based practice in primary care?
A. Using only randomized controlled trials to guide treatment decisions
B. Integrating best research evidence with clinical expertise and patient values
C. Following clinical practice guidelines without deviation
D. Prioritizing cost-effectiveness over patient preference
CORRECT ANSWER: B. Integrating best research evidence with clinical expertise and patient
values
Rationale: Evidence-based practice is a triad: best available research evidence, clinician
expertise, and patient preferences/values. This framework ensures individualized, high-quality
care. Rigid adherence to guidelines or single study types ignores clinical context and patient
autonomy.
Question 7: A 34-year-old female presents with acute onset of unilateral facial droop,
inability to close the eye, and loss of forehead wrinkles. There is no limb weakness or speech
difficulty. What is the most likely diagnosis?
A. Ischemic stroke
B. Bell's palsy
C. Myasthenia gravis
D. Trigeminal neuralgia
CORRECT ANSWER: B. Bell's palsy
, Rationale: Bell's palsy is an acute, idiopathic, peripheral facial nerve (CN VII) palsy characterized
by unilateral facial weakness including the forehead (distinguishing it from central causes like
stroke). Absence of other neurological deficits supports this diagnosis. Stroke typically spares
the forehead due to bilateral cortical innervation.
Question 8: Which vaccination is recommended for all adults aged 65 years and older,
regardless of comorbidities?
A. Hepatitis B vaccine
B. Recombinant zoster vaccine (RZV)
C. Meningococcal conjugate vaccine
D. Human papillomavirus (HPV) vaccine
CORRECT ANSWER: B. Recombinant zoster vaccine (RZV)
Rationale: CDC/ACIP recommends two doses of recombinant zoster vaccine (Shingrix) for
immunocompetent adults aged ≥50 years, and especially for those ≥65, to prevent herpes
zoster and postherpetic neuralgia. Other vaccines are indicated based on risk factors,
occupation, or specific conditions.
Question 9: A patient with chronic low back pain without radiculopathy or red flags requests
imaging. According to Choosing Wisely recommendations, what is the most appropriate
response?
A. Order lumbar spine X-rays to rule out fracture
B. Order MRI to evaluate for disc herniation
C. Defer imaging and initiate conservative management
D. Refer immediately to orthopedic surgery
CORRECT ANSWER: C. Defer imaging and initiate conservative management
Rationale: For non-specific low back pain without red flags (e.g., trauma, neurologic deficit,
cancer history, infection signs), imaging does not improve outcomes and may lead to
unnecessary procedures. First-line management includes education, activity modification,
NSAIDs, and physical therapy.
Question 10: Which finding is most suggestive of heart failure with reduced ejection fraction
(HFrEF) on physical examination?
A. Elevated jugular venous pressure
B. S4 gallop
C. Laterally displaced apical impulse
D. Bibasilar crackles
CORRECT ANSWER: C. Laterally displaced apical impulse
Rationale: A laterally displaced, diffuse apical impulse suggests left ventricular dilation,
characteristic of HFrEF. While JVD, crackles, and S3 (not S4) may occur in heart failure, they are
less specific. S4 is associated with diastolic dysfunction (HFpEF).
Question 11: A 60-year-old smoker presents with progressive dyspnea and chronic cough.
Spirometry shows FEV1/FVC ratio of 0.58 post-bronchodilator. What is the most appropriate
initial pharmacologic therapy?
A. Inhaled corticosteroid monotherapy
B. Long-acting muscarinic antagonist (LAMA)
