Critical Care Nursing Practice Questions

Correct Answer: A

Rationale: The correct answer is A: "Do you feel safe in your home?" This question is most appropriate because it directly addresses the potential issue of elder abuse without assuming or accusing the patient. It allows the patient to disclose any safety concerns and initiates a conversation about their well-being. Options B and D are inappropriate as they are accusatory and may escalate the situation. Option C is not as direct and may not effectively address the safety concerns of the patient.

Correct Answer: B

Rationale: Certainly. Hypovolemia, or low blood volume, can lead to low cardiac output and cardiac index because the heart has less blood to pump, resulting in reduced circulation. Exercise typically increases cardiac output to meet increased demand. Myocardial infarction may reduce cardiac output temporarily, but not consistently. Shock, a condition where the body's tissues do not receive enough oxygen and nutrients, can lead to low cardiac output, making it a possible cause.

Correct Answer: A

Rationale: The correct answer is A because it aligns with the ethical principle of patient autonomy, which emphasizes the patient's right to make decisions about their own care. Withholding or withdrawing life-sustaining treatments, including nutrition, antibiotics, and blood products, respects the patient's autonomy. This choice also reflects the principle of beneficence, as it aims to prevent unnecessary suffering and respects the patient's wishes. Option B is incorrect because it focuses on pain and anxiety management rather than the broader ethical considerations of withholding life-sustaining treatments. Option C is incorrect because withdrawing life-sustaining treatments while a patient is receiving paralytic agents can pose additional risks and complications, potentially conflicting with the principles of nonmaleficence and beneficence. Option D is incorrect because the primary goal of withdrawing or withholding treatments is not to hasten death but to respect the patient's autonomy and quality of life. This choice does not align with the ethical principles of patient-centered care.

Correct Answer: B

Rationale: The correct answer is B: Self-directed study of best practice for the patients she cares for. This choice aligns with the Synergy Model by promoting individualized patient care based on best practices. Self-directed study allows the nurse to enhance their knowledge and skills to provide optimal care tailored to each patient's unique needs. Attending mandatory in-service programs (A) may not directly support the individualized care approach. Gathering demographic data (C) is important but not specific to the Synergy Model's focus on patient acuity and nurse competencies. Participating in a research study (D) may contribute to evidence-based practice, but it does not directly relate to the Synergy Model's emphasis on aligning nurse competencies with patient needs.

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.
