Question 1
What is the normal percentage of oxygen in room air?
A. 15%
B. 21%
C. 25%
D. 30%
CORRECT ANSWER: B. 21%
RATIONALE:
Room air contains approximately 21% oxygen. Anything above this is considered a
medical administration and requires a provider order.
, Question 2
A patient's telemetry pulse reading appears off. What should the nurse do first?
A. Replace the telemetry battery
B. Assess the patient and obtain an apical pulse, then check the stickers
C. Document the reading as is
D. Notify the provider immediately
CORRECT ANSWER:
B. Assess the patient and obtain an apical pulse, then check the stickers
RATIONALE:
When a telemetry reading is abnormal or questionable, the nurse should first assess
the patient and obtain a manual apical pulse, then check electrode placement and
connections before assuming the reading is accurate.
Question 3
What is the recommended LDL cholesterol level for heart health?
A. Less than 100
B. Less than 130
C. Less than 160
D. Less than 200
CORRECT ANSWER: B. Less than 130
RATIONALE:
LDL (low-density lipoprotein) is considered "bad" cholesterol that can clog blood
vessels. The recommended level is less than 130 mg/dL. HDL should be greater than
45, and total cholesterol should be less than 200.
, Question 4
Which lab value is elevated with cardiac cell death, indicating a myocardial
infarction?
A. Hemoglobin
B. Creatinine kinase and troponin
C. C-reactive protein
D. Serum electrolytes
CORRECT ANSWER: B. Creatinine kinase and troponin
RATIONALE:
Creatinine kinase (CK) and troponin are cardiac enzymes that are released into the
bloodstream when cardiac muscle cells die. Elevated levels indicate myocardial
infarction (heart attack).
Question 5
What is preload?
A. The resistance the ventricle must overcome to eject blood
B. The amount of blood and pressure in the ventricle at the end of diastole
C. Heart rate multiplied by stroke volume
D. The volume of blood ejected per heartbeat
CORRECT ANSWER:
B. The amount of blood and pressure in the ventricle at the end of diastole
RATIONALE:
Preload is the volume of blood in the ventricle at the end of diastole, which stretches
the cardiac muscle fibers. It increases with increased blood volume (e.g., fluid
overload).
, Question 6
What is afterload?
A. The amount of blood in the ventricle at end of diastole
B. The resistance that has to be exceeded for the ventricle to eject blood during
systole
C. Heart rate × stroke volume
D. The pressure in the pulmonary artery
CORRECT ANSWER:
B. The resistance that has to be exceeded for the ventricle to eject blood
during systole
RATIONALE:
Afterload is the systemic vascular resistance that the left ventricle must overcome to
eject blood. It increases with hypertension or vasoconstriction, making the heart work
harder.
Question 7
What is the formula for cardiac output?
A. Stroke volume × heart rate
B. Preload × afterload
C. Blood pressure × heart rate
D. Ejection fraction × stroke volume
CORRECT ANSWER: A. Stroke volume × heart rate
RATIONALE:
Cardiac output is the amount of blood pumped by the heart per minute. It is
calculated as stroke volume (the amount of blood pumped per beat) multiplied by
heart rate.
