Question 1 of 5.
Extract:The following scenario applies to the next 1 items The nurse cares for a client following a cardiac arrest Item 1 of 1 Admission Notes 2000 - 36-year-old was found unresponsive and with no pulse after collapsing at his job. Cardiopulmonary resuscitation (CPR) was started at the scene. The client was successfully resuscitated in the emergency department. The client was intubated, and central vascular access was established. 2130 - The client was transferred to the intensive care unit. Shortly after the transfer, the client converted to ventricular fibrillation. Code blue was called. CPR was delivered over 2 minutes, and a palpable carotid pulse was not assessed. The client's current cardiac monitor shows asystole.
The next essential intervention is the administration of…………… followed by ……………….. for a client in asystole post-cardiac arrest.
A. Epinephrine
B. Amiodarone
C. Sodium bicarbonate
D. Defibrillation
E. Resuming CPR
F. Cardioversion
Explanation: Epinephrine is given in asystole to stimulate cardiac activity. E: Correct - CPR resumes immediately after medication to restore circulation. B, C, D, F: Incorrect - Amiodarone, sodium bicarbonate, defibrillation, and cardioversion are not indicated for asystole.
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?
A
B
C
D
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.
