Critical Care Nursing Practice Questions

Correct Answer: C

Rationale: The correct answer is C (10 to 20 mg/dL). The normal BUN-to-creatinine ratio is approximately 10:1. With a serum creatinine level of 0.7 mg/dL, the expected BUN level should be around 7 to 14 mg/dL. Therefore, choice C (10 to 20 mg/dL) falls within this expected range. Choices A, B, and D are incorrect as they do not align with the typical BUN-to-creatinine ratio and would indicate abnormal kidney function.

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: C

Rationale: The correct answer is C because notifying the organ procurement organization (OPO) once the patient has been pronounced brain dead is a requirement to sustain CMS Conditions of Participation. This step ensures that the proper protocols are followed for organ donation. Choice A is incorrect because notifying the OPO of impending death is not a requirement for sustaining CMS Conditions of Participation. Choice B is incorrect because obtaining informed consent for organ donation is not directly related to meeting the requirements of CMS Conditions of Participation. Choice D is incorrect because while evaluating the patient's suitability for organ donation is important, it is not a specific requirement under CMS Conditions of Participation.

Correct Answer: A

Rationale: Rationale: Accurately identifying patients is a National Patient Safety Goal to prevent errors in patient care. Proper patient identification ensures correct treatments and medications are given, reducing harm. Restraint elimination, medication reconciliation, and infection reduction are important goals but not specific National Patient Safety Goals. Accurate patient identification directly addresses patient safety concerns.

Correct Answer: D

Rationale: The correct answer is D because brushing off any visible powder on the skin and clothing is the first step in managing exposure to powdered lime. This action helps to remove the source of exposure and prevent further absorption through the skin. It is crucial to prevent additional contact and reduce the risk of further harm. Obtaining vital signs (choice A) and a complete blood count (choice B) can be important but should come after the initial decontamination. Decontaminating the patient by showering with water (choice C) is not recommended for lime exposure as it can react with water and cause further injury.
