QUESTIONS AND VERIFIED ANSWERS
1. A 68-year-old male with a 40-pack-year smoking history presents
with exertional leg pain that resolves within 2-3 minutes of rest.
Which vascular condition is most consistent with these symptoms?
A) Venous insufficiency
B) Peripheral arterial disease
C) Deep vein thrombosis
D) Varicose veins
Answer: B Peripheral arterial disease is characterized by intermittent
claudication - pain with exercise that resolves with rest. The calf muscle
is the most common site of pain due to inadequate blood supply during
increased metabolic demand. This distinguishes PAD from venous
disease, which typically presents with aching, heaviness, and swelling
that worsens with dependency and improves with elevation.
2. A patient presents with a murmur that is best heard at the left
sternal border, radiates to the neck, and is described as a crescendo-
decrescendo systolic ejection murmur. What is the most likely
diagnosis?
A) Mitral stenosis
B) Aortic stenosis
,C) Mitral regurgitation
D) Aortic regurgitation
Answer: B Aortic stenosis produces a systolic ejection murmur best
heard at the right upper sternal border with radiation to the carotid
arteries. The crescendo-decrescendo quality and systolic timing are
classic. Symptoms indicating worsening include dyspnea, angina, and
syncope, representing the classic triad of advanced aortic stenosis
requiring intervention.
3. A 45-year-old female has been taking lisinopril for 3 weeks and now
reports a persistent dry, nonproductive cough. What is the most
appropriate management strategy?
A) Add an antitussive medication
B) Discontinue lisinopril and switch to an ARB
C) Increase the lisinopril dose
D) Add a bronchodilator
Answer: B ACE inhibitor-induced cough typically begins within the first
2 weeks of therapy and is characterized by a dry, persistent,
nonproductive cough. This is a class effect due to accumulation of
bradykinin. Switching to an angiotensin receptor blocker (ARB)
eliminates the cough while maintaining similar cardiovascular benefits,
as ARBs do not affect bradykinin metabolism.
4. A 72-year-old female with a history of hypertension presents with
progressive shortness of breath, fatigue, and peripheral edema.
,Auscultation reveals crackles in the lung bases and an S3 gallop. Which
medication class is contraindicated and may exacerbate her condition?
A) Beta-blockers
B) ACE inhibitors
C) NSAIDs
D) Diuretics
Answer: C NSAIDs can exacerbate heart failure through several
mechanisms including sodium and fluid retention, increased systemic
vascular resistance, and reduced renal blood flow due to prostaglandin
inhibition. They decrease the effectiveness of diuretics and ACE
inhibitors, potentially leading to worsening HF symptoms, fluid
overload, and decompensation.
5. A 55-year-old male with poorly controlled hypertension for over 10
years is undergoing a comprehensive cardiovascular assessment.
Where is the point of maximal impulse (PMI) most likely located?
A) 4th intercostal space, midclavicular line
B) 5th intercostal space, midclavicular line
C) 5th intercostal space, left of midclavicular line
D) 6th intercostal space, anterior axillary line
Answer: C Chronic poorly controlled hypertension leads to left
ventricular hypertrophy and eventually left ventricular dilation. This
causes the PMI to displace laterally and inferiorly from its normal
position at the 5th intercostal space, midclavicular line. A PMI located at
the 5th ICS, left of the MCL indicates significant left ventricular
enlargement.
, 6. A 64-year-old patient with type 2 diabetes presents with a wound
on the great toe that is not healing. He reports that his legs hurt when
walking but the pain resolves when he stops. Which finding would
most strongly confirm the suspected diagnosis?
A) Diminished pedal pulses with pallor on elevation
B) Warm, erythematous skin with pitting edema
C) Visible superficial veins with brownish discoloration
D) Ulceration located at the medial malleolus
Answer: A Peripheral arterial disease in diabetic patients manifests as
diminished or absent pulses, pallor with leg elevation, and dependent
rubor. The combination of exertional leg pain (intermittent claudication)
and nonhealing wounds in a diabetic patient strongly suggests PAD.
Diabetes is a significant nonmodifiable risk factor for PAD.
7. A 38-year-old Hispanic male with a known diastolic murmur at the
mitral listening point has been followed for two years without an
audible click. What is the most probable valvular lesion?
A) Mitral valve prolapse
B) Aortic regurgitation
C) Mitral stenosis
D) Tricuspid stenosis
Answer: C Mitral stenosis produces a diastolic murmur best heard at
the apex (mitral listening point) with no audible click. It is the most
common valvular complication of chronic rheumatic heart disease. The
murmur is a low-pitched, rumbling diastolic murmur with an opening
