Question 1 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 2 of 5
A nurse is caring for a client who is in the compensatory stage of shock. Which of the following findings should the nurse expect?
Correct Answer: B
Rationale: Tachycardia (e.g., 160/min) is a compensatory mechanism in shock to maintain cardiac output and perfusion.
Question 3 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.
Extract:
pH 7.22
PaCO2 68 mm Hg
Base excess-2 PaO2 78 mm Hg
Saturation 80%
Bicarbonate 26 mEq/L
Question 4 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.

Question 5 of 5
A nurse is caring for a client with a ventricular pacemaker who is on ECG monitoring. The nurse understands that the pacemaker is functioning properly when which of the following appears on the monitor strip?
Correct Answer: A
Rationale: Pacemaker spikes before each QRS complex indicate proper ventricular pacing, stimulating ventricular depolarization.
