SECTION 1: ADVANCED PHYSICAL ASSESSMENT (Questions 1-60)
Q1. A 58-year-old male presents with progressive dyspnea on exertion
and orthopnea. On cardiac auscultation, an S4 gallop is heard at the
apex. Which pathophysiologic process best explains this finding?
A. Decreased ventricular compliance with atrial contraction against a stiff
ventricle
B. Rapid ventricular filling in early diastole
C. Volume overload with ventricular dilation
D. Mitral valve regurgitation during systole
,Answer: A. Decreased ventricular compliance with atrial contraction
against a stiff ventricle
Rationale: An S4 gallop occurs when a noncompliant ventricle receives atrial
"kick" in late diastole, commonly seen in hypertension, aortic stenosis, and
diastolic dysfunction. S3 represents rapid early filling, volume overload
causes S3, and MR causes a holosystolic murmur .
Mnemonics to Remember: S4 = "Stiff" ventricle (atrial kick against
resistance); S3 = "Sloshing" in (rapid filling into dilated ventricle) .
Q2. A 42-year-old female reports a unilateral, throbbing headache
with photophobia and nausea lasting 8-12 hours. She notes visual aura
preceding the headache. Which is the most likely diagnosis?
A. Tension-type headache
B. Migraine with aura
C. Cluster headache
D. Sinus headache
Answer: B. Migraine with aura
Rationale: Unilateral throbbing pain with photophobia, nausea, and visual
aura is classic for migraine with aura. Tension headaches are bilateral and
pressing, cluster headaches are periorbital with autonomic symptoms and
lack aura, and sinus headaches present with facial pain and purulent
discharge .
Key Diagnostic Clue: Presence of any aura (visual, sensory, speech)
immediately distinguishes migraine from other primary headache
disorders .
,Q3. A new screening test for colon cancer has a sensitivity of 92% and
specificity of 85%. In a population of 1,000 with a disease prevalence
of 5%, approximately how many true positive results will occur?
A. 25
B. 46
C. 92
D. 50
Answer: B. 46
Rationale: True positives = sensitivity × prevalence × population = 0.92 ×
0.05 × 1,000 = 46. False positives would be 0.15 × 950 = 142.5.
Understanding how prevalence affects predictive value is essential for test
interpretation .
APEA Tip: For screening test calculations, always draw a 2×2 table.
Sensitivity and specificity are intrinsic test properties, but PPV/NPV depend
on prevalence .
Q4. A 35-year-old male presents with acute right knee pain after a
twisting injury. The Lachman test is positive. Which structure is most
likely injured?
A. Medial collateral ligament
B. Lateral collateral ligament
C. Anterior cruciate ligament
D. Posterior cruciate ligament
, Answer: C. Anterior cruciate ligament
Rationale: The Lachman test is the most sensitive test for ACL injury (90-
95% sensitivity). MCL injury is tested with valgus stress, LCL with varus
stress, and PCL with posterior drawer .
Exam Strategy: Lachman = ACL. It is more sensitive than the anterior
drawer test, especially in acute injuries when muscle guarding limits drawer
testing .
Q5. During a cardiac exam, the NP auscultates a harsh crescendo-
decrescendo systolic murmur at the right upper sternal border
radiating to the carotids. Which valvular lesion is most consistent?
A. Aortic stenosis
B. Mitral regurgitation
C. Aortic regurgitation
D. Mitral stenosis
Answer: A. Aortic stenosis
Rationale: A harsh crescendo-decrescendo systolic murmur at the right
upper sternal border with carotid radiation is classic for aortic stenosis.
Mitral regurgitation is holosystolic at the apex, aortic regurgitation is
diastolic, and mitral stenosis is diastolic with an opening snap .
Q6. What is a possible cause of jugular venous distention (JVD) in a
patient?
