Nclex Questions Management of Care

1. Under what circumstances can an individual receive medical care without giving informed consent?

Correct answer: B

Rationale: An individual may receive medical care without giving informed consent in an emergency, life-or-death situation. This exception allows healthcare providers to provide immediate treatment to save a person's life or prevent serious harm when time is of the essence. Choices A, C, and D are incorrect because in all other situations, informed consent is required. The durable power of attorney for health care should be involved if available, the physician should have a discussion with the client in non-life-threatening situations, and in cases where clients are unable to speak for themselves, their designated representative or responsible party should be involved in the consent process.

2. How often should physical restraints be released?

Correct answer: A

Rationale: The correct answer is to release physical restraints every 2 hours. Releasing restraints every 2 hours helps prevent complications associated with prolonged immobilization. Releasing restraints every 30 minutes (choice C) may be too frequent and disruptive to the client's care. Releasing restraints between 1 and 3 hours (choice B) introduces variability that could lead to inconsistencies in care. Releasing restraints at least every 4 hours (choice D) does not adhere to the recommended frequency of every 2 hours.

3. The client is unsure about making medical decisions as their disease progresses and wants to appoint someone to make these decisions. Which of the following options would be most appropriate?

Correct answer: C

Rationale: The correct answer is 'a healthcare proxy.' A healthcare proxy involves the client appointing an individual to make medical decisions on their behalf if they become unable to do so. This option allows the client to choose someone they trust to act in their best interests. Choice A, 'a living will,' is a legal document that outlines a person's wishes regarding medical treatment in case they are unable to communicate their decisions. While it is important, it does not involve appointing someone to make decisions. Choice B, 'informed consent,' is a process where a healthcare provider explains a treatment or procedure, including its risks and benefits, to a patient who can then decide whether to proceed. This is not about appointing someone to make decisions on the patient's behalf. Choice D, 'non-informed consent,' is not a valid concept in healthcare. Informed consent is crucial for respecting a patient's autonomy and decision-making capacity.

4. The LPN is preparing to clean a client's PEG tube.The following tasks should the nurse perform EXCEPT?

Correct answer: B

Rationale: When cleaning a client's PEG tube, the nurse should perform tasks that focus on gentle cleaning and avoiding potential irritants. Choice A is correct as gently removing crusty drainage helps maintain hygiene. Choice C is important to prevent skin irritation and infection. Choice D is appropriate for cleaning the area. Choices B and D are incorrect. Choice B is incorrect because pulling the tube in multiple directions can lead to dislodgement or injury. Choice B is incorrect as talcum powder may irritate the stoma, and it is generally not recommended near PEG tubes.

5. In which of the following conditions might increased cortisol levels be found?

Correct answer: A

Rationale: Cushing's syndrome is characterized by increased cortisol levels due to the overproduction of cortisol by the adrenal glands. This excess cortisol can lead to various symptoms and complications. Addison's disease is associated with decreased cortisol levels as it results from adrenal insufficiency, making it an incorrect choice in this context. Renal failure and congestive heart failure are not typically linked to abnormal cortisol levels, further indicating that they are not the conditions where increased cortisol levels are found.
