ATI Advanced Med Surg Exam 3 Questions
Extract:
Question 1 of 5
A client with acute respiratory distress syndrome (ARDS) shows no improvement despite increases in concentration in oxygen administered. What intervention should the nurse attempt which may improve ventilation-perfusion matching?
Correct Answer: A
Rationale: Prone positioning improves ventilation-perfusion matching in ARDS by redistributing ventilation to better-perfused lung regions.
Question 2 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.
Question 3 of 5
A patient develops increasing dyspnea and hypoxemia 2 days after heart surgery. What procedure should the nurse anticipate assisting with to determine whether the patient has acute respiratory distress syndrome (ARDS) or pulmonary edema caused by heart failure?
Correct Answer: A
Rationale: A pulmonary artery catheter measures pressures to differentiate ARDS from heart failure-related pulmonary edema.
Question 4 of 5
A nurse is caring for a client who is unconscious and has a breathing pattern characterized by alternating periods of hyperventilation and apnea. The nurse should document that the client has which of the following respiratory alterations?
Correct Answer: B
Rationale: Cheyne-Stokes respirations involve alternating hyperventilation and apnea, often seen in neurological or heart failure conditions.
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.
