Critical Care Nursing Practice Questions Questions

Question 1 of 5

The patient�s serum creatinine level is 0.7 mg/dL. The expected BUN level should be

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.

Question 2 of 5

A 54-year-old patient arrives in the emergency department (ED) after exposure to powdered lime at work. Which action should the nurse take first?

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.

Question 3 of 5

The patient has a Glasgow Coma Scale (GCS) score of 3 and discussions have been held with the family about withdrawing life support. Which statemen t by the nurse best describes requirements that must be met to sustain Centers for Medicare and Medicaid Services (CMS) Conditions of Participation?

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.

Question 4 of 5

Assuming each of these patients was discharged from the hospital, which older adult patient is at greatest risk for decreased functional status and quality of life?

Correct Answer: A

Rationale: The correct answer is A because this patient had a complex surgery with complications, requiring long-term care and loss of a significant other, which can impact their emotional well-being and support system. This can lead to decreased functional status and quality of life. Choice B is incorrect as the patient has support from a spouse and manages health care independently, indicating a good support system. Choice C is incorrect as the patient is cognitively intact and social, which suggests a good quality of life. Choice D is incorrect as the patient had a less complex procedure, well-managed diabetes, and was living independently, which indicates a lower risk for decreased functional status and quality of life compared to choice A.

Question 5 of 5

The nurse is caring for a terminally ill patient who has 20-second periods of apnea followed by periods of deep and rapid breathing. Which action by the nurse would be most appropriate?

Correct Answer: D

Rationale: The correct answer is D because the patient is exhibiting Cheyne-Stokes breathing pattern characterized by periods of apnea followed by deep and rapid breathing. The nurse should document this pattern accurately. Option A is incorrect as suctioning is not indicated. Option B may worsen the respiratory pattern. Option C is not specifically related to addressing the breathing pattern.
