ATI RN Custom 2023 Med-Surg Cardiovascular Questions
Extract:
Question 1 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.
Question 2 of 5
A nurse is reviewing medications prescribed for a client. For which of the following prescriptions should the nurse contact the provider for clarification?
Correct Answer: C
Rationale: Regular insulin dosing requires clarification on timing and frequency (e.g., how many meals), as vague orders can lead to administration errors.
Question 3 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 4 of 5
A client with Sinus tachycardia has been admitted into the telemetry unit. The nurse identifies the following as possible causes of sinus tachycardia. Select all that apply
Correct Answer: A,C,E
Rationale: Fever, albuterol (a beta-agonist), and dehydration can increase heart rate, causing sinus tachycardia, while lisinopril and sleeping typically do not.
Question 5 of 5
A nurse is caring for a client who has a serum potassium level of 5.9 mEq/L. The provider prescribes polystyrene sulfonate. If this medication is effective, the nurse should expect which of the following changes on the client's ECG?
Correct Answer: C
Rationale: Polystyrene sulfonate reduces serum potassium levels. Hyperkalemia causes peaked T waves on an ECG, so effective treatment would result in a reduction of this abnormality.
