part 4 exam review questions Flashcards
What lab test is used to evaluate a pt being treated for heart failure?
BNP
A patient is scheduled for a cardiac catheterization with coronary angiography. What information should the nurse provide before
the procedure?
a. It will be important not to move at all during the procedure.
b. A flushed feeling is common when the contrast dye is injected.
c. Monitored anesthesia care will be provided during the procedure.
d. Arterial pressure monitoring will be needed for 24 hours after the test.
b. A flushed feeling is common when the contrast dye is injected.
A patient will be evaluated for rhythm disturbances with a Holter monitor. What should the nurse teach the patient to do?
a. Connect the recorder to a computer once daily.
b. Exercise more than usual while the monitor is in place.
c. Remove the electrodes when taking a shower or tub bath.
d. Keep a diary of daily activities while the monitor is worn.
d. Keep a diary of daily activities while the monitor is worn.
The nurse has received the laboratory results for a patient who developed chest pain 4 hours ago and may be having a myocardial
infarction. Which laboratory test result should be most helpful in indicating myocardial damage?
a. Troponins
b. Myoglobin
c. Homocysteine (Hcy)
d. Creatine kinase-MB (CK-MB)
a. Troponins
Cardiac troponins start to elevate 4 to 6 hours after myocardial injury and are highly specific to myocardium. They are the preferred
diagnostic marker for myocardial infarction.
Which information obtained by the nurse who is admitting the patient for magnetic resonance imaging (MRI) will be important to
report to the health care provider before the MRI?
a. The patient has an allergy to shellfish.
b. The patient has a history of atherosclerosis.
c. The patient has a permanent cardiac pacemaker.
d. The patient took the prescribed heart medications today.
c. The patient has a permanent cardiac pacemaker.
When the nurse is monitoring a patient who is undergoing exercise (stress) testing on a treadmill, which assessment finding
requires the most rapid action by the nurse?
a. Patient reports feeling tired
b. Sinus tachycardia at a rate of 110 beats/min
c. Inversion of T waves on the electrocardiogram
d. Blood pressure (BP) increase from 134/68 to 150/80 mm Hg
c. Inversion of T waves on the electrocardiogram
When admitting a patient for a cardiac catheterization and coronary angiogram, which information about the patient is important
for the nurse to communicate to the health care provider before the test?
a. The patient’s pedal pulses are +1.
b. The patient is allergic to shellfish.
c. The patient had a heart attack 1 year ago.
d. The patient has not eaten anything today.
b. The patient is allergic to shellfish.
The nurse is reviewing the laboratory results for newly admitted patients on the cardiovascular unit. Which laboratory result is
most important to communicate rapidly to the health care provider?
a. High troponin I level
b. Increased triglyceride level
c. Very low homocysteine level
d. Elevated C-reactive protein level
a. High troponin I level
The elevation in troponin I indicates that the patient has had an acute myocardial infarction.
