NSG 554 Exam 3 Cardiovascular Nursing 2026 | Most Tested
Questions & Verified Answers | Latest Update | Graded A+
1. If the P-R interval is 0.48 seconds, the nurse would suspect.......
Purkinje system is not conducting the impulse
The atria are slow to repolarize
The SA node is misfiring
Impulse delay is longer than normal at the AV node
2. Describe the significance of measuring the atrial rate in assessing cardiac
function.
Measuring the atrial rate is not relevant to cardiac health.
Measuring the atrial rate helps identify potential delays in impulse
conduction through the atria, which can indicate arrhythmias.
Measuring the atrial rate provides information about respiratory
function.
Measuring the atrial rate is primarily used to assess blood pressure
levels.
3. What is the primary purpose of administering heparin to a patient with
NSTEMI?
To enhance oxygen delivery
To increase heart rate
To prevent blood clot formation
To lower blood pressure
,4. The nurse is providing teaching for a client who is being sent home with a
Holter monitor. Which information is important for the nurse to include in the
teaching?
Do not eat or drink during the monitoring period.
The computer will record electrical heart signals for 20 minutes.
Press the button on the monitor if symptoms occur.
This test will show the blood flow through heart valves.
5. A patient has a junctional escape rhythm. Which action should the nurse
make a priority?
Prepare for a pacemaker insertion.
Eliminate caffeine from the diet.
Contact the physician immediately for emergency orders.
Assess the patient for symptoms associated with this rhythm.
6. The nurse is caring for a client with newly diagnosed Prinzmetal's (variant)
angina and has a prescription for amlodipine. Which of the following
information is accurate about amlodipine?
Decrease spasm of the coronary arteries
Help prevent clotting in the coronary arteries
Reduce the 'fight or flight' response
Increase the force of myocardial contraction
,7. A patient arrives at the community healthcare center complaining of chest
pain. After diagnosis, the healthcare provider has prescribed amlodipine for
the patient's condition. Which of the following conditions should the nurse
identify as an indication for amlodipine therapy?
Sick sinus syndrome
Cardiogenic shock
Atrioventricular (AV) block
Prinzmetal's angina
8. What is the appropriate action a patient should take if they experience chest
pain after taking sublingual nitroglycerin?
Wait 10 minutes before taking any action.
Drink a glass of water to ease the pain.
Take another dose of nitroglycerin immediately.
Call an ambulance if pain persists after 5 minutes.
9. Describe the rationale for using NSAIDs in the management of pericarditis-
related chest pain.
NSAIDs increase heart rate and improve cardiac output.
NSAIDs enhance the effectiveness of other cardiac medications.
NSAIDs prevent blood clots in the coronary arteries.
NSAIDs reduce inflammation and alleviate pain associated with
pericarditis.
10. What is the first action a nurse should take for an unconscious and pulseless
patient with a chaotic cardiac monitor pattern?
, Administer oxygen
Call for a code blue
Check the patient's blood pressure
Initiate cardiopulmonary resuscitation (CPR)
11. Describe the potential implications of multifocal premature ventricular
contractions (PVCs) in a patient with coronary artery disease.
Multifocal PVCs may suggest increased myocardial irritability and a
higher risk of arrhythmias.
Multifocal PVCs are always benign and require no further assessment.
Multifocal PVCs are only a concern in patients with heart failure.
Multifocal PVCs indicate that the heart is functioning normally.
12. Describe the primary purpose of an ECG in monitoring cardiovascular
health.
An ECG is used to monitor blood pressure levels.
An ECG provides imaging of the heart's structure.
An ECG is used to assess the electrical activity of the heart and
identify arrhythmias or other cardiac issues.
An ECG measures the heart's pumping efficiency and blood flow.
13. Describe the significance of a systolic blood pressure (SBP) of 120 mmHg in
assessing hemodynamic stability.
A systolic blood pressure of 120 mmHg is irrelevant to hemodynamic
assessment.
A systolic blood pressure of 120 mmHg indicates adequate
perfusion and hemodynamic stability.
