ATI Med Surg exam 2 III Questions
Extract:
Question 1 of 5
A nurse is admitting a client who has acute heart failure following a myocardial infarction (MI). The nurse recognizes that which of the following prescriptions by the provider requires clarification?
Correct Answer: A
Rationale: Administering 0.9% normal saline IV at 50 mL/hr continuously in acute heart failure can exacerbate fluid overload, worsening symptoms like pulmonary edema.
Question 2 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.
Question 3 of 5
A nurse is evaluating a client who had a left-sided cardiac catheterization with an upper extremity insertion site. Which of the following actions should the nurse take?
Correct Answer: A
Rationale: Assessing pulses in the affected arm ensures proper blood flow and identifies potential complications like arterial occlusion following cardiac catheterization.
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
Examine the attached ECG image and identify the type of arrhythmia present. The ECG shows a series of wide QRS complexes occurring at a rapid rate.
Correct Answer: B
Rationale: Ventricular tachycardia is characterized by a rapid rate and wide QRS complexes. This rhythm originates in the ventricles and can lead to a decrease in cardiac output and possible deterioration into ventricular fibrillation.
