Question 1 of 5
Which of the following factors can directly affect cardiac output?
Correct Answer: B,C
Rationale: Stroke volume and heart rate directly determine cardiac output, as cardiac output equals stroke volume multiplied by heart rate.
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
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
A nurse is caring for a client who is receiving positive-pressure mechanical ventilation. Which of the following interventions should the nurse implement to prevent complications? (Select all that apply.)
Correct Answer: B,D,E
Rationale: Daily verification of ventilator settings ensures safety, pantoprazole prevents stress ulcers, and elevating the head of the bed reduces ventilator-associated pneumonia risk.

Nurse's Notes
Client came to the ER for increase SOB worsening dyspnea and restlessness. Respiratory rate is currently 32/min with shallow breath BP 198/78 mm Hg. Oxygen has been increased from 2 L nasal cannula to 50% face mask with little improvement of oxygen saturation. Current oxygen saturation is 91% on 50% facemask. Arterial blood gases drawn and sent to lab.
Diagnostic Results
