ATI RN Custom 2023 Med-Surg Cardiovascular Questions
Extract:
Question 1 of 5
A nurse in an urgent care center is assessing a client who reports a sudden onset of irregular palpitations, fatigue, and dizziness. The nurse finds a rapid and irregular heart rate on the cardiac monitor. Which dysrhythmias should the nurse expect to find on the EKG?
Correct Answer: D
Rationale: Symptoms of irregular palpitations, fatigue, and dizziness with a rapid, irregular heart rate are classic for atrial fibrillation.
Question 2 of 5
A patient on the telemetry unit develops atrial flutter with a heart rate of 150, respirations 26, b/p 118/64 and a O2 saturation of 90% while sitting down. Which action should the nurse do FIRST?
Correct Answer: D
Rationale: With an O2 saturation of 90%, the priority is to address hypoxia by administering supplemental oxygen first to improve oxygenation.
Question 3 of 5
The nurse on the unit hears an alarm sound in the client's room. Arriving in the room, the client is unresponsive, pulseless and the nurse sees the flat rhythm on the monitor. What is the FIRST action by the nurse?
Correct Answer: C
Rationale: A flat rhythm (asystole) requires immediate CPR as the first action to restore circulation, as defibrillation is not indicated for asystole.
Question 4 of 5
A nurse is teaching a client with angina pectoris about starting therapy with nitroglycerin tablets. The nurse should include which of the following instructions regarding how to take the medication?
Correct Answer: A
Rationale: Nitroglycerin is administered sublingually for rapid absorption to relieve chest pain. The standard instruction is to take one tablet every 5 minutes up to 3 doses if chest pain persists, then seek medical help if unrelieved.
Question 5 of 5
The nurse notes a client in supraventricular tachycardia. The patient has a pulse and the cardiac monitor is at the bedside. The nurse understands electrical intervention is indicated. What button does the nurse push to ensure the electricity is delivered on the R wave? Refer to the picture.
Correct Answer: D
Rationale: Synchronized cardioversion delivers a shock on the R wave to avoid the vulnerable T wave period, reducing the risk of inducing ventricular fibrillation. The SYNC button ensures this timing.
