<LATEST VERSION>
1. A 65-year-old patient with a history of hypertension and type 2 diabetes presents for a
routine physical. Their blood pressure today is 142/92 mmHg. According to the JNC 8
guidelines, what is the most appropriate initial pharmacologic treatment?
A. ACE Inhibitor
B. Thiazide Diuretic
C. Beta-Blocker
D. Calcium Channel Blocker
✓ A. ACE Inhibitor
Rationale: For patients with diabetes and hypertension, JNC 8 guidelines recommend initiating
pharmacologic treatment with an ACE inhibitor or an ARB. This is due to their protective effects
on the kidneys and their efficacy in this patient population.
2. A 4-year-old child presents with a 24-hour history of discrete, "teardrop" vesicles on an
erythematous base, some appearing in the mouth and scalp. The child is afebrile but itchy.
What is the most likely diagnosis?
A. Hand, Foot, and Mouth Disease
B. Impetigo
C. Varicella Zoster (Chickenpox) ✓
D. Scabies
Rationale: The description of teardrop vesicles on different stages of healing, appearing on the
scalp and in the mouth, is classic for varicella (chickenpox). Hand, Foot, and Mouth disease
typically presents with vesicles limited to the palms, soles, and oral mucosa.
3. The mother of a 2-month-old infant is concerned because her baby's head "looks flat on
one side." The cranial sutures are open and the fontanelles are soft and flat. The condition
corrects itself when the infant's head is repositioned. What is the most likely diagnosis?
A. Craniosynostosis
B. Positional Plagiocephaly ✓
C. Hydrocephalus
D. Caput Succedaneum
Rationale: Positional plagiocephaly is a common, reversible flattening of the infant's skull due to
,prolonged pressure on one area. It improves with repositioning. Craniosynostosis involves the
premature fusion of cranial sutures and does not correct with repositioning.
4. A patient with chronic kidney disease (Stage 3) requires analgesia for osteoarthritis. Which
medication should be AVOIDED due to the risk of worsening renal function?
A. Acetaminophen
B. Naproxen ✓
C. Tramadol
D. Topical Capsaicin
Rationale: NSAIDs like naproxen can cause reduced renal blood flow and acute kidney injury,
especially in patients with pre-existing chronic kidney disease. Acetaminophen is the first-line
analgesic in this population.
5. During a well-woman exam, a 30-year-old patient asks about cervical cancer screening. She
has no history of abnormal Pap smears or HPV. According to the USPSTF, what is the
recommended screening interval for her?
A. Pap smear alone every 3 years
B. HPV testing alone every 5 years
C. Co-testing (Pap and HPV) every 5 years ✓
D. Annual Pap smear
Rationale: For women aged 30-65, the USPSTF recommends screening every 5 years with co-
testing (Pap and HPV) or every 3 years with a Pap smear alone. Co-testing every 5 years is a
preferred and common strategy.
6. A 55-year-old male presents with sudden onset of severe, tearing back pain. His blood
pressure is 180/110 mmHg in the right arm and 150/95 mmHg in the left arm. What is the
most critical initial diagnosis to rule out?
A. Acute Myocardial Infarction
B. Aortic Dissection ✓
C. Pulmonary Embolism
D. Ruptured Abdominal Aortic Aneurysm
Rationale: The classic presentation of a thoracic aortic dissection includes sudden, severe
tearing or ripping pain, hypertension, and a blood pressure differential between arms due to
the dissection compromising blood flow to one subclavian artery.
7. A patient with heart failure is started on Lisinopril. Which lab value must be monitored
most closely within 1-2 weeks after initiation?
A. Sodium
B. Potassium ✓
C. Calcium
, D. Liver Enzymes (AST/ALT)
Rationale: ACE inhibitors like Lisinopril can cause hyperkalemia by inhibiting aldosterone
secretion. Monitoring potassium and renal function is essential after starting or titrating the
dose.
8. The NP suspects a patient has bacterial vaginosis. Which finding on wet mount preparation
is diagnostic?
A. Budding yeast and hyphae
B. Motile, flagellated organisms
C. Clue Cells ✓
D. Numerous White Blood Cells
Rationale: Clue cells (vaginal epithelial cells studded with bacteria) are the hallmark diagnostic
finding for bacterial vaginosis. Budding yeast suggest candidiasis, and motile flagellated
organisms suggest trichomoniasis.
9. A 70-year-old patient is diagnosed with community-acquired pneumonia and will be
treated as an outpatient. He has no comorbidities and no recent antibiotic use. What is the
most appropriate first-line antibiotic?
A. Amoxicillin ✓
B. Azithromycin
C. Levofloxacin
D. Doxycycline
Rationale: For healthy adults with no comorbidities and no antibiotic use in the last 3 months,
the IDSA/ATS guidelines recommend Amoxicillin as first-line. Macrolides or Doxycycline are
alternatives.
10. A newborn has a positive Barlow-Ortolani maneuver. This finding is most consistent with:
A. Developmental Dysplasia of the Hip ✓
B. Clubfoot (Talipes Equinovarus)
C. Brachial Plexus Palsy
D. Congenital Scoliosis
Rationale: The Barlow (dislocatable hip) and Ortolani (reducible hip) maneuvers are specific
physical exam tests for developmental dysplasia of the hip in newborns.
11. A 45-year-old female presents with fatigue, weight gain, cold intolerance, and dry skin.
Her TSH is elevated, and her Free T4 is low. What is the diagnosis?
A. Primary Hypothyroidism ✓
B. Subclinical Hypothyroidism
C. Hyperthyroidism
D. Secondary Hypothyroidism
