NSG 223 Med-Surg 2 Exam 1 2026 | Practice Questions
& Verified Answers | Medical-Surgical Nursing Review
1. What is the primary purpose of catheter ablation therapy?
To increase heart rate during exercise
To replace damaged heart valves
To improve blood flow in coronary arteries
To destroy specific cells causing tachyarrhythmias
2. Describe how plaque buildup in the coronary arteries affects heart
function.
Plaque buildup has no effect on heart function.
Plaque buildup strengthens the arterial walls.
Plaque buildup narrows the arteries, reducing the delivery of
oxygen-rich blood to the heart.
Plaque buildup increases blood flow to the heart.
3. What is the correct dosing for administration of nitroglycerin sublingual
tablets?
One tablet every hour.
Two tablets every four hours.
Three tablets every six hours.
One tablet every 15 minutes for up to three doses.
4. What type of EKG is typically performed during the course of a stress
test?
5-lead EKG
, Holter monitoring
3-lead continuous monitoring
5. Describe the significance of proper electrode placement in a 5-lead
ECG monitoring.
Electrode placement is only important for stress tests, not
continuous monitoring.
Electrode placement is irrelevant to the accuracy of the ECG.
Proper electrode placement ensures accurate readings of the
heart's electrical activity.
Electrode placement only affects the visual appearance of the
ECG printout.
6. What is the primary cause of coronary artery disease (CAD)?
Plaque build-up in the coronary arteries that restricts blood
flow, causing ischemia.
Excessive dilation of the coronary arteries, leading to increased
blood flow and potential vessel rupture.
A genetic predisposition to myocardial infarction, independent of
lifestyle factors and without the involvement of arterial plaque.
Hyperactive platelet aggregation in healthy arteries, leading
directly to myocardial infarction without preceding ischemia.
7. Describe the significance of the P wave and T wave in an ECG reading.
The P wave shows the heart rate, and the T wave shows blood
pressure.
The P wave indicates ventricular contraction, and the T wave
indicates atrial relaxation.
, The P wave represents atrial depolarization, while the T wave
represents ventricular repolarization.
The P wave indicates electrical inactivity, while the T wave
indicates electrical activity.
8. The Watchman is new technology to reduce ____ risk in patients with ___.
hospitalization; CHF
stroke; afib
stroke; pulmonary embolism
heart attack; angina
9. Which medication is commonly used to manage symptoms of
cardiomyopathy?
Antihistamines
Antibiotics
Antidepressants
Diuretics
10. A patient reports chest pain that occurs unpredictably and at rest.
Based on this information, which type of angina should the healthcare
provider suspect?
Silent angina
Prinzmetal angina
Unstable angina
Stable angina
, 11. A patient is taking warfarin for a recent mechanical mitral valve
replacement. What is the patient's INR goal range?
3-4
2-3
1.5 - 2
2.5 - 3.5
12. Which of the following is a known cause of cardiomyopathy?
Diabetes mellitus
Hypertension
Heavy alcohol use
Coronary artery disease
13. A priority nursing consideration following a TEE (transesophageal
echo) would be
monitoring intake & output q1h
keeping the client on bedrest for at least 24 hours
checking peripheral pulses q2h
withholding fluids until the gag reflex returns
14. Describe the mechanism by which catheter ablation therapy addresses
tachyarrhythmias.
It involves the implantation of a pacemaker to regulate
heartbeats.
It uses high-frequency sound waves to create thermal injury
and destroy localized cells responsible for the arrhythmia.
It involves surgical removal of the heart tissue.
