ANSWERS ) ALREADY GRADED A+.
Your patient admitted with an NSTEMI develops acute shortness
of breath, recurrence of chest pain, and a loud systolic murmur
at the apex of the heart.
Which of the following has most likely occurred?
(A) the patient has developed acute mitral valve regurgitation
(B) the patient has developed acute infarction
(C) the patient has developed acute mitral wave stenosis
(D) the patient has developed acute ventricular septal defect -
ANSWER-(A) The location of the murmur, at the apex of the
heart (midclavicular, 5th ICS), is one clue to this answer. In
addition, regurgitation occurs when the valve should be
closed and the mitral valve should be closed during systole.
Mitral stenosis, choice (C), occurs when the mitral valve is
open. Additionally, mitral stenosis cannot be acute, it
develops gradually.
The location or type of acute MI is often associated with specific
clinical findings.
,Which of the following statements related to location of MI is
TRUE?
(A) anterior MI is often associated with heart blocks and
bradyarrythmias
(B) inferior MI is often associated with right ventricular wall
infarction
(C) lateral MI is most likely to be associated with posterior MI
(D) posterior MI is most likely to lead to the complication of heart
failure - ANSWER-(B) Because most inferior MI are due to
RCA occlusion and the RCA also supplies blood to the right
ventricular muscle wall, inferior MI is associated with RV
infarct.
Which of following statements is accurate regarding heart
valves?
(A) the aortic valve is closed during
systole (B) the mitral valve is closed
during systole
(C) the mitral valve is closed during diastole
(D) the aortic valve is open during diastole - ANSWER-(B) During
systole (left ventricular ejection) the aortic valve is open,
allowing for ejection, and the mitral valve is closed at this
time. The mitral valve is open during filling (diastole).
, The following drugs are all considered positive inotropic drugs
primarily affecting the beta-1 reception in the heart, EXCEPT for:
(A) dopamine drip at 12 mcg/kg/min dose
(B) dopamine drip at 5 mcg/kg/min dose
(C) dobutamine drip at 7 mcg/kg/min dose
(D) milrinone at 7 mcg/kg/min dose - ANSWER-(A) At high doses
(> 10 mcg/kg/min), dopamine stimulates alpha receptors in
arteries and causes vasoconstriction. The other 3
drugs/doses affect mainly beta-1 receptors in the heart,
producing a positive inotropic effect.
Which of the following is associated with mitral regurgitation?
(A) Systolic murmur, sinus bradycardia
(B) Diastolic murmur, heart failure
(C) Systolic murmur, inferior wall myocardial infarction
(D) Diastolic murmur, complete heart block - ANSWER-(C)
Inferior wall MI may result in ischemia and dysfunction
(regurgitation) of the mitral valve. The mitral valve is closed
during systole (left ventricular ejection). A murmur is
produced when the mitral valve is not fully closed during
systole.
Nitrate therapy is indicated for the treatment of unstable angina
and acute heart failure because it:
(A) decreases preload and increases myocardial O2 demand
