ATI Advanced Med Surg Exam 3 Questions
Extract:
Question 1 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 2 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 3 of 5
A nurse is caring for a patient with acute respiratory distress syndrome (ARDS) who is receiving mechanical ventilation using synchronized intermittent mandatory ventilation (SIMV). The settings include fraction of inspired oxygen (FIO2) of 80%, tidal volume of 450, rate of 16/minute, and positive end-expiratory pressure (PEEP) of 5 cm. Which assessment finding is most important for the nurse to report to the health care provider?
Correct Answer: D
Rationale: Crackles at lung bases indicate worsening pulmonary edema or fluid accumulation, requiring immediate reporting to adjust ventilator settings or interventions.
Question 4 of 5
A nurse is caring for a client who reports heart palpitations. An ECG confirms the client is experiencing ventricular tachycardia (VT). The nurse should anticipate the need for taking which of the following actions?
Correct Answer: A
Rationale: Elective cardioversion is appropriate for stable ventricular tachycardia with a pulse, as it synchronizes electrical shock to restore normal rhythm.
Question 5 of 5
The nurse is caring for a client with a history of heart failure and notes a new onset of the following rhythm on the client's telemetry monitor. Which action would the nurse take first?
Correct Answer: B
Rationale: Obtaining vital signs first assesses the hemodynamic impact of new-onset atrial fibrillation, guiding further actions.
