Question 1 of 5.

The nurse is caring for a client with the below tracing on the electrocardiogram (ECG). The client reports dyspnea and dizziness. The nurse should obtain a prescription for which medication? See the image below.

A. Diltiazem

B. Amiodarone

C. Labetalol

D. Atropine

Explanation: Amiodarone is used for ventricular arrhythmias (e.g., ventricular tachycardia), which may cause dyspnea and dizziness.

Question 2 of 5.

The nurse is caring for a client with the below tracing on the electrocardiogram. The nurse should expect the client to demonstrate which clinical manifestation in conjunction with this electrocardiogram tracing? See the exhibit.

A. Jugular venous distention (JVD)

B. Systolic murmur

C. Irregular pulse

D. Widened pulse pressure

Explanation: An irregular ECG tracing, such as in atrial fibrillation, typically correlates with an irregular pulse due to inconsistent ventricular contractions.

Question 3 of 5.

The nurse is caring for a client who was recently admitted to the cardiac floor for angina. This client states that their chest pain occurs at the same time every day at rest. The client does not believe there are any precipitating factors. Which of the following types of angina is this client most likely experiencing?

A. Variant angina

B. Stable angina

C. Unstable angina

D. Nonanginal pain

Explanation: Variant (Prinzmetal's) angina occurs at rest, often at predictable times, due to coronary artery spasm, not exertion, unlike stable or unstable angina.

Question 4 of 5.

The nurse assesses the following electrocardiogram (ECG) strips for assigned clients. The nurse should immediately follow up with the client with which ECG strip?

Explanation: Without specific ECG details, the nurse prioritizes the strip indicating life-threatening arrhythmias (e.g., ventricular tachycardia or fibrillation) requiring immediate intervention.

Question 5 of 5.

The nurse is caring for a client with cardiac tamponade. Which vital signs are expected?

A. HR: 109 bpm; RR: 26; BP: 88/71 mmHg

B. HR: 90 bpm; RR: 32; BP: 90/52 mmHg

C. HR: 115 bpm; RR: 22; BP: 140/78 mmHg

D. HR: 54 bpm; RR: 14; BP: 161/52 mmHg

Explanation: Cardiac tamponade causes tachycardia (HR >100), increased respiratory rate, and hypotension due to restricted cardiac output.
