patient appears comfortable at rest. Currently, she is afebrile and hemodynamically
stable. Physical examination reveals bibasilar crackles. The patient's troponin-T level
is normal. What changes are more likely to be seen on an electrocardiogram (ECG) if
this patient is a suspected case of unstable angina? - ANSWER: Deep, symmetric T-
wave inversions in V2 and V3 accompanied by flat ST-segment
What heart sound would one hear in a patient with systolic congestive heart failure
(CHF)? - ANSWER: S3 heart sound
A 72-year-old man with a recent history of a large anterior wall myocardial infarction
complains of dyspnea on exertion, orthopnea, and increasing pedal edema. There is

mellitus, and hyperlipidemia. His vital signs are oxygen saturation 98% on room air,
respiratory rate 18 breaths/min, heart rate 91 bpm, blood pressure 131/91 mm Hg,
and temperature 98.6 °F (37 °C). A 12-lead electrocardiogram (ECG) demonstrates ST
depressions in leads V5, V6, and aVL. The patient is administered oxygen, morphine,
nitroglycerin, and aspirin. What is the principle behind giving this patient
nitroglycerin? - ANSWER: To dilate the venous system and decrease cardiac preload.
A 70-year-old patient comes to the clinic with complaints of increased blood
pressure. He was diagnosed with hypertension 10 years ago. His other problems

blood pressure is 160/80 mmHg. His medications include lisinopril, amlodipine,
atorvastatin, calcium and vitamin D supplements, and bisphosphonates. He does not
exercise and smokes a pack of cigarettes daily. He drinks two glasses of beer every
day. Family history is significant for stroke in father and MI in his sister. Which of the
following is the most likely effect of increased blood pressure on his heart? -
ANSWER: Left ventricular (concentric) hypertrophy
A middle-aged patient with diabetes mellitus is referred to the clinic by his primary
care provider to diagnose heart failure. The patient states that he does not have any
documentation or labs from his previous medical encounters. Which of the following
is the most significant and earliest sign of heart failure? - ANSWER: An S3 gallop
A woman presents with chronic fatigue and trouble breathing. Upon inspection,

distension, pulmonary crackles, a non-tender distended abdomen, and bulging
flanks. The liver is non-palpable. Which of the following is the best assessment of this
patient? - ANSWER: There is a pathologic buildup of fluid in her peritoneum due to
abnormal changes in her hydrostatic pressure due to a CHF exacerbation. Her serum
albumin is 4 g/dL, and ascitic fluid albumin is 2 g/dL.
