While getting a 71-year old male patient's history, the
patient tells the nurse that he has mitral stenosis. The
nurse would anticipate which of the following findings?
a) Systolic murmur, sinus bradycardia
b) Systolic murmur, atrial fibrillation
c) Diastolic murmur, atrial fibrillation
d) Diastolic murmur, sinus bradycardia -
....ANSWER...Answer C
Murmurs of stenosis occur when the valve is open, and the
mitral valve is open during the filling phase of the heart
cycle. Chronic resistance produced by stenosis of the mitral
valve will result in an enlarged left atrium, which in turn
may lead to atrial fibrillation, not sinus bradycardia.
During systole, the mitral valve is closed. Therefore,
mitral regurgitation would cause a systolic murmur.
,The patient was admitted with an acute anterior wall MI
and suddenly develops a loud holosystolic murmur,
loudest at the left sternal border, 5th intercostal space,
tachypnea, and bibasilar crackles. Which of the following
would provide the most definitive diagnosis of this
problem?
a) Decreased Cardiac output
b) Increased oxygen saturation in the pulmonary artery and
the right ventricle
c) Central venous pressure less the pulmonary artery
diastolic pressure
d) Decreased arterial saturation - ....ANSWER...Answer B
The clinical picure is one of ventricular septal defect (based
on location of the murmur and the patient's chief
presenting problem.) The 02 saturation on the right side of
the heart would be expected to be g=higher than normal f
arterial blood from the left ventricle is shunting into the
right ventricle
Which of the following may be a result of pulmonary
hypertension?
a) Pulmonic stenosis
,b) Left ventricular failure
c) Tricuspid regurgitation
d) Increased lung compliance - ....ANSWER...Answer C
The pulmonary pressure get increasingly high with
pulmonary hypertension, which causes right ventricular
strain and dilation, which in turn may result in an
inability of the tricuspid valve to close fully. Pulmonary
hypertension does not cause pulmonic stenosis, left
ventricular failure, or increased lung compliance. Right
ventricular failure and decreased lung compliance are more
likely.
The patient develops PSVT, and synchronized
cardioversion is being considered. Which of the following
would be a contraindication to the cardioversion?
a) Digoxin level of 4.0 mg/dL
b) Potassium level of 5.1 mgEq/L
c) Magnesium level of 2.6 mg/dL
d) Creatinine level of 3.1 mg/dL - ....ANSWER...Answer A
If synchronized cardioversion is attempted in the presence
of digoxin toxicity, ventricular tachycardia or fibrillation
may result. The remaining 3 options would not be
contraindicated to synchronized cardioversion
, When there is a drop in cardiac output, which of the
following is a normal compensatory response?
a) Increased oxygen extraction
b) Deceased oxygen consumption
c) Decreased heart rate
d) Increased oxygen delivery - ....ANSWER...Answer A
Oxygen utilization is about 300 mL/min, where as oxygen
delivery is 1,000 mL/min. If the CO decreases, myocardial
extraction will increase. The heart rate will alos increase. A
drop in oxygen consumption and a decrease in heart rate
do not occur with a drop in CO. If the CO drops, oxygen
delivery will decrease, not increase.
On arrival to the ICU from the cardiac catheterization lab
where the patient had a diagnostic right heart
catheterization and a percutaneous coronary intervention,
the cardiologist informed the nrse that the patient had an
elevated left ventricular filling pressure and a low CO.
Which of the following therapies would be beneficial for
this patient?
a) Left ventricular afterload reduction
b) Heart rate reduction
