ATI RN
ATI Med Surg exam 2 III Questions
Question 1 of 5
A nurse is interpreting the ECG strip of a client who has bradycardia. Which of the following cardiac components should the nurse identify as the role of the P wave?
Correct Answer: C
Rationale: Atrial depolarization is the correct role of the P wave. It represents the electrical activity that leads to atrial contraction. Normal duration is 0.06 to 0.12 seconds.
Question 2 of 5
A nurse is teaching a client who has angina about nitroglycerin sublingual tablets. Which of the following statements should the nurse include in the teaching?
Correct Answer: B
Rationale: Nitroglycerin dilates cardiac blood vessels to deliver more oxygen to the heart. This action helps relieve the chest pain associated with angina by increasing blood flow.
Question 3 of 5
A nurse is monitoring a client who is on telemetry. Which of the following findings on the ECG strip should the nurse recognize as normal sinus rhythm?
Correct Answer: D
Rationale: The P wave falling before the QRS complex is a key characteristic of normal sinus rhythm, representing the orderly conduction of electrical impulses from atria to ventricles.
Question 4 of 5
A nurse on a medical-surgical unit is caring for a client who reports pain in the jaw, back, and shoulder, shortness of breath, and nausea. Which of the following actions should the nurse take?
Correct Answer: D
Rationale: Obtaining an EKG is crucial for diagnosing myocardial infarction by assessing electrical activity of the heart. It helps identify ischemia or infarction. Early detection of abnormalities ensures prompt treatment and reduces complications.
Question 5 of 5
A nurse is teaching a newly licensed nurse about evaluating a cardiac rhythm. Which of the following options should the nurse identify as the P wave in the ECG complex?
Correct Answer: A
Rationale: The first upward deflection in an ECG represents the P wave, indicating atrial depolarization. It precedes the QRS complex and corresponds to the electrical activity associated with atrial contraction, initiating the cardiac cycle.
