Question 1 of 5
A nurse is caring for a client who has an endotracheal tube and is receiving mechanical ventilation. Which of the following actions should the nurse take to reduce the risk of ventilator-associated pneumonia?
Correct Answer: D
Rationale: Regular oral hygiene with a suction toothbrush reduces bacterial load, decreasing the risk of ventilator-associated pneumonia.
Question 2 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 3 of 5
Which assessment finding by the nurse caring for a patient receiving mechanical ventilation indicates the need for suctioning?
Correct Answer: D
Rationale: A drop in oxygen saturation to 93% suggests airway obstruction or secretions, indicating the need for suctioning.
Question 4 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 5 of 5
A client is admitted to the emergency room with a respiratory rate of 7/min. Arterial blood gases (ABG) reveal the following values. Which of the following is an appropriate analysis of the ABGS?
Correct Answer: C
Rationale: Low pH and elevated PaCO2 indicate respiratory acidosis due to hypoventilation retaining carbon dioxide.
