ATI Advanced Med Surg Exam 3 Questions
Extract:
Question 1 of 5
A nurse is assessing a client who has atrial fibrillation. Which of the following pulse characteristics should the nurse expect?
Correct Answer: A
Rationale: Atrial fibrillation causes an irregularly irregular pulse due to chaotic atrial activity and inconsistent ventricular responses.
Question 2 of 5
An older patient with cardiogenic shock is cool and clammy. Hemodynamic monitoring indicates a high systemic vascular resistance (SVR). Which intervention should the nurse anticipate?
Correct Answer: B
Rationale: Sodium nitroprusside reduces high SVR, improving perfusion in cardiogenic shock with vasoconstriction.
Question 3 of 5
A nurse is interpreting a client's ECG strip. Which of the following components of the ECG should the nurse examine to determine the time it takes for ventricular depolarization and repolarization?
Correct Answer: B
Rationale: The QT interval measures the time for ventricular depolarization and repolarization, from QRS onset to T wave end.
Question 4 of 5
Norepinephrine has been prescribed for a patient who was admitted with dehydration and hypotension. Which data indicate that the nurse should consult with the health care provider before starting the norepinephrine?
Correct Answer: A
Rationale: Low central venous pressure indicates hypovolemia, requiring fluid resuscitation before vasopressors like norepinephrine to prevent worsening hypotension.
Question 5 of 5
Which of the following is an appropriate nursing intervention for a patient with a pulmonary artery catheter?
Correct Answer: D
Rationale: Monitoring central venous pressure is appropriate as the catheter provides data on fluid status and right ventricular function.
