Critical Care Nursing Practice Questions

Correct Answer: A

Rationale: The correct answer is A: Elevate head of bed to 30 degrees. Elevating the head of the bed helps promote optimal airway clearance by facilitating drainage of secretions and reducing the risk of aspiration. This position also improves lung expansion and oxygenation. Choice B is important for preventing venous thromboembolism but not directly related to airway clearance. Choice C may not be appropriate as excessive sedation can impair airway clearance. Choice D is important for preventing pressure ulcers but does not directly address airway clearance.

Correct Answer: C

Rationale: The correct answer is C because BIS and PSI monitors provide both raw EEG data and a numeric value, simplifying the interpretation of patient sedation levels. Raw EEG data offers detailed information on brain activity, while the numeric value allows for quick assessment. This simplifies the monitoring process compared to interpreting raw EEG data alone. Choice A is incorrect as BIS and PSI monitors are not restricted to heavily sedated patients. Choice B is incorrect as they are not limited to pediatric patients. Choice D is incorrect as the number of leads required does not determine the simplicity of use; it is the data interpretation that matters.

Correct Answer: B

Rationale: The correct answer is B: Provide emotional support and comfort measures. In the final stages of dying, the focus shifts from curative treatment to providing comfort and dignity. Emotional support helps alleviate anxiety and fear, promoting a peaceful transition. Comfort measures like pain management improve quality of life. Encouraging the patient to eat may be futile as the body shuts down. Performing frequent assessments for recovery signs is not appropriate in this situation. Implementing aggressive interventions could go against the patient's wishes for a natural death.

Correct Answer: B

Rationale: The correct answer is B because effective communication ensures that the patient's wishes and values are understood and respected, leading to informed decision-making. It also promotes shared decision-making among the patient, family, and healthcare team, enhancing the quality of care. Choices A, C, and D are incorrect because while they are important aspects of end-of-life care, they do not address the core element of communication in facilitating meaningful and informed decisions.

Correct Answer: D

Rationale: The correct answer is D because monitoring the surgical incision for signs of infection is essential post-VAD implantation to prevent complications. This step is crucial in early identification and treatment of any potential infection, which can lead to serious outcomes. A) Giving immunosuppressive medications is not typically required for VAD implantation, as the primary goal is to support cardiac function rather than prevent rejection. B) Preparing the patient for a permanent VAD is premature, as the goal is often to bridge to transplantation or recovery, not permanent VAD placement. C) Teaching the patient the reason for complete bed rest is not necessary for VAD implantation, as patients are typically encouraged to gradually increase activity levels under guidance.
