Critical Care Nursing Practice Questions Questions
Question 1 of 5
Which statement is true regarding oral care for the prevention of ventilator-associated pneumonia (VAP)? (Select all that apply.)
Correct Answer: B
Rationale: The correct answer is B. Implementing a comprehensive oral care program is an intervention for preventing VAP. This statement is true because proper oral care, including brushing teeth, oral suctioning, and using chlorhexidine gluconate, has been shown to reduce the risk of VAP by decreasing the colonization of pathogenic bacteria in the oral cavity. Regular oral care helps maintain oral hygiene and reduce the risk of aspiration of bacteria into the lungs, which is a common cause of VAP. Incorrect Answer Analysis: A: Tooth brushing every 2 hours may be excessive and could potentially cause harm to the oral mucosa, leading to increased risk of infection. C: While oral suctioning and brushing teeth are important components of oral care, the statement is not comprehensive enough to address the full range of interventions needed to prevent VAP. D: While chlorhexidine gluconate can be effective in preventing VAP, the statement implies that it is the only effective intervention, which is not true.
Question 2 of 5
The primary health care provider writes an order to discon tinue a patient’s left radial arterial line. When discontinuing the patient’s invasive line, what is the priority nursing action?
Correct Answer: B
Rationale: The correct answer is B: Apply pressure to the insertion site for 5 minutes. This is the priority nursing action because it helps prevent bleeding and hematoma formation after removing the arterial line. Applying pressure for 5 minutes allows for adequate hemostasis. A: Applying an air occlusion dressing to the insertion site is not the priority action. It does not address the immediate need to control bleeding. C: Elevating the affected limb on pillows for 24 hours is not necessary and does not address the immediate need for hemostasis. D: Keeping the patient's wrist in a neutral position is not the priority action when discontinuing an arterial line. It does not address the need for hemostasis and preventing bleeding.
Question 3 of 5
The charge nurse is supervising care for a group of patients monitored with a variety of invasive hemodynamic devices. Which patient should the charge nurse evaluate first?
Correct Answer: C
Rationale: The correct answer is C because a pulmonary artery occlusion pressure of 25 mm Hg indicates possible fluid overload or cardiac issue requiring urgent evaluation. This value is high, suggesting increased pressure in the left side of the heart. Additionally, the oxygen saturation of 89% on 3 L of oxygen indicates potential respiratory compromise. This patient needs immediate assessment and intervention to prevent worsening of their condition. Choice A is incorrect as a central venous pressure of 6 mm Hg is within normal limits, and the urine output is adequate. Choice B is incorrect as a BP of 110/60 mm Hg is acceptable, and a slightly dampened arterial waveform is not an immediate concern. Choice D is incorrect as a pulmonary artery pressure of 25/10 mm Hg is within normal range, and an oxygen saturation of 94% on 2 L of oxygen is acceptable.
Question 4 of 5
The nurse is caring for a patient with an arterial monitoring system. The nurse assesses the patient’s noninvasive cuff blood pressure to be 70/40 mm Hg. The arterial blood pressure measurement via an intraarterial catheter in the same arm is assessed by the nurse to be 108/70 mm Hg. What is the best action by the nurse?
Correct Answer: C
Rationale: Rationale for Correct Answer (C - Assess the cuff for proper arm size): 1. The cuff blood pressure (70/40 mm Hg) is significantly lower than the arterial blood pressure (108/70 mm Hg). 2. Discrepancy suggests cuff size mismatch, leading to inaccurate readings. 3. Assessing cuff size ensures accurate blood pressure measurement. 4. Ensures appropriate interventions based on accurate readings. Summary of Incorrect Choices: A: Rapid response not warranted based solely on blood pressure discrepancy. B: Trendelenburg position not indicated for cuff size issue. D: Normal saline bolus not appropriate without accurate blood pressure measurement.
Question 5 of 5
The nurse is caring for a patient with a left radial arterial lianbierb, .caonmd/t eas tp ulmonary artery catheter inserted into the right subclavian vein. Which action by th e nurse best ensures the safety of the patient being monitored with invasive hemodynamic moni toring lines?
Correct Answer: C
Rationale: The correct answer is C: Zero reference the system daily. Zero referencing ensures accuracy and calibration of pressure monitoring system by setting the baseline pressure to zero. This is crucial to prevent inaccuracies in measurements. Choice A is important but doesn't directly address the accuracy of the monitoring system. Choice B may help in preventing errors but doesn't address the accuracy of pressure measurement. Choice D is important for alerting the nurse but doesn't directly relate to the accuracy of hemodynamic monitoring.
