Extract:
Question 1 of 5
A nurse is monitoring a client who is receiving a unit of packed RBCs following surgery. Which of the following assessments is an indication that the client might be experiencing circulatory overload?
Correct Answer: C
Rationale: Dyspnea indicates pulmonary congestion from circulatory overload, a common complication of rapid blood transfusion.
Question 2 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 3 of 5
A nurse is collecting a medication history from a client who is scheduled to have a cardiac catheterization. Which of the following medications taken by the client interacts with contrast material and places the client at risk for acute kidney injury?
Correct Answer: B
Rationale: Metformin can increase the risk of lactic acidosis when combined with contrast material, especially in patients with renal impairment, requiring careful monitoring or temporary discontinuation.
Question 4 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 5 of 5
A nurse is caring for a client who is postoperative and whose respirations are shallow and 9/min. Which of the following acid-based imbalances should the nurse identify the client as being at risk for developing initially?
Correct Answer: B
Rationale: Shallow, slow respirations cause CO2 retention, leading to respiratory acidosis as the initial acid-base imbalance.
