,1. A 64-year-old male with a history of heart failure and chronic kidney disease presents with
an acute gout flare. Which medication should be avoided for acute management?
A) Colchicine
B) Indomethacin
C) Prednisone
D) Methylprednisolone
Rationale : NSAIDs like indomethacin cause sodium retention, worsen heart failure
exacerbations, and decrease renal perfusion, making them contraindicated in patients with
severe CKD and heart failure. Systemic corticosteroids are safer alternatives.
2. During a routine physical exam of a 28-year-old female, the clinician notes a mid-systolic
click followed by a late systolic murmur at the apex. This finding is indicative of:
A) Aortic stenosis
B) Mitral valve prolapse
C) Mitral regurgitation
D) Tricuspid regurgitation
Rationale: A mid-systolic click followed by a late systolic murmur at the apex is the classic
auscultatory presentation of mitral valve prolapse (MVP), common in young adult females.
3. An 8-month-old infant is brought to the clinic with intermittent abdominal pain, drawing up
of the legs, and passing "currant-jelly" stools. Examination reveals a sausage-shaped mass in
the right upper quadrant. What is the definitive diagnostic and therapeutic intervention?
A) Abdominal ultrasound
B) Air or contrast enema
C) Immediate surgical laparotomy
D) CT scan of the abdomen
Rationale : The presentation describes intussusception. While ultrasound is highly sensitive for
diagnosis, an air or hydrostatic contrast enema is both diagnostic and therapeutic, often
reducing the invagination.
4. A 45-year-old patient with type 2 diabetes mellitus and established chronic kidney disease
with significant albuminuria requires antihypertensive optimization. Which agent is the drug
of choice?
A) Amlodipine
B) Hydrochlorothiazide
C) Lisinopril
,D) Metoprolol succinate
Rationale : ACE inhibitors like lisinopril (or ARBs) provide efferent arteriolar vasodilation,
reducing intraglomerular pressure and offering renal protection beyond blood pressure control
in diabetic nephropathy.
5. When examining a patient's eyes, the provider notes a yellow-white, slightly raised benign
growth on the nasal side of the conjunctiva that does not extend over the cornea. This is
documented as a:
A) Pterygium
B) Pinguecula
C) Chalazion
D) Xanthelasma
Rationale : A pinguecula is a raised, yellowish conjunctival nodule that does not grow over the
cornea. A pterygium is a fleshy growth that encroaches onto the cornea.
6. A 68-year-old patient requires a new medication for insomnia. According to the Beers
Criteria, which characteristic of a hypnotic medication is most critical to reduce accumulation
risk?
A) High lipid solubility
B) Short half-life (< 24 hours)
C) Hepatic CYP450 induction
D) Long elimination half-life
Rationale : Geriatric prescribing requires choosing drugs with a short half-life (<24 hours) to
prevent active metabolite accumulation, reducing the risk of daytime sedation, confusion, and
falls.
7. A 3-week-old neonate is evaluated for forceful, non-bilious projectile vomiting immediately
after feeding. A small, olive-shaped mass is palpable in the right upper quadrant. This
condition is caused by:
A) Hypertrophy of the pyloric sphincter muscle
B) Congenital absence of ganglionic cells in the colon
C) Aganglionosis of the lower esophageal sphincter
D) Incomplete rotation of the midgut loops
Rationale : Hypertrophic pyloric stenosis causes projectile, non-bilious vomiting and is classic for
a palpable olive-like mass in the epigastrium or RUQ.
8. A patient presents with a highly pruritic, vesicular rash arranged in a linear pattern across
their forearm after working in their yard. What is the pathophysiological mechanism of this
reaction?
, A) Type I IgE-mediated hypersensitivity
B) Type II antibody-dependent cytotoxicity
C) Type III immune complex deposition
D) Type IV cell-mediated delayed hypersensitivity
Rationale : Allergic contact dermatitis (e.g., poison ivy) is a Type IV delayed-type hypersensitivity
reaction mediated by T-lymphocytes, typically presenting 24–48 hours after exposure.
9. A 35-year-old female presents with fatigue, weight gain, cold intolerance, and a sluggish
relaxation phase of her deep tendon reflexes. Which laboratory pattern confirms primary
hypothyroidism?
A) Low TSH, Low Free T4
B) High TSH, Low Free T4
C) High TSH, High Free T4
D) Low TSH, High Free T4
Rationale : In primary hypothyroidism, the thyroid gland fails to produce sufficient thyroid
hormone, removing negative feedback and causing a compensatory rise in serum TSH.
10. A provider auscultates a low-pitched, rumbling diastolic murmur at the cardiac apex. The
patient is placed in the left lateral decubitus position to amplify the sound. This murmur
represents:
A) Aortic regurgitation
B) Mitral stenosis
C) Mitral regurgitation
D) Tricuspid stenosis
Rationale : Mitral stenosis produces a low-pitched, rumbling diastolic murmur heard best at the
apex with the bell of the stethoscope in the left lateral decubitus position.
11. Which diagnostic lab result is most characteristic of iron deficiency anemia?
A) Low MCV, Low ferritin
B) High MCV, Low B12
C) Low MCV, High ferritin
D) Normal MCV, High reticulocytes
Rationale : Iron deficiency anemia is a microcytic anemia (Low MCV) with depleted iron stores,
characteristically demonstrated by low serum ferritin levels.
12. A 19-year-old college student presents with a sore throat, fever, and severe fatigue.
Physical exam reveals posterior cervical lymphadenopathy and splenomegaly. What
diagnostic test is most specific?
