Correct Answer: D

Rationale: The correct answer is a five-year-old in skeletal traction. This task is within the scope of practice for an LPN and would need minimal assistance from an RN. The children with diabetic ketoacidosis, sickle cell crisis, and dehydration require close observation, good assessment skills, IVF needs, and medications that would be better managed by an RN. Reassigning the child in skeletal traction to an LPN ensures appropriate care while allowing the RN to focus on the more critical cases.

Correct Answer: C

Rationale: The correct action is to immediately discontinue the use of the IVAC pump and obtain a replacement because the frayed cord poses a safety risk to the client. Continuing to use the pump with visible wiring could lead to electric shock or other serious harm to the client. Notifying maintenance to come and check the pump immediately (Choice A) may cause unnecessary delays in ensuring the client's safety. Continuing with the administration of the antibiotic and filling out an equipment maintenance request (Choice B) is unsafe as it ignores the immediate danger. Tagging the equipment for maintenance (Choice D) does not address the urgent need to protect the client from harm.

Correct Answer: D

Rationale: The correct answer is to attend to the care needs of the returning postoperative client just exiting the elevator first. In a healthcare setting, patient care should always take precedence, especially for complex or unstable clients requiring immediate assessment and care. The physician's loud verbal direction, the nursing supervisor going to a meeting, and unit staff leaving on a break are important but do not involve direct patient care. Therefore, the nurse should prioritize responding to the returning postoperative client to ensure their immediate needs are met.

Correct Answer: A

Rationale: The hypothalamus is responsible for regulating sleep patterns among other functions. Injury to the hypothalamus can disrupt the sleep-wake cycle, leading to excessive sleepiness or changes in sleep patterns. Choices B, C, and D are incorrect as they do not primarily control sleep regulation. The thalamus is involved in relaying sensory information, the cortex is responsible for higher brain functions, and the medulla controls vital functions such as heartbeat and breathing.

Correct Answer: D

Rationale: When a client with a nasogastric (NG) tube begins vomiting, the nurse should first check the NG tube placement. Vomiting can be a sign of tube displacement, which can lead to serious complications. Retaping the tube (Choice A), clamping it (Choice B), or removing it (Choice C) without first assessing its placement can be harmful or ineffective. Checking the NG tube placement is crucial as it ensures that the tube is in the correct position and prevents potential complications. Retaping the NG tube (Choice A) is incorrect because the priority is to check the placement first. Clamping the NG tube (Choice B) or removing it (Choice C) without verifying the placement can be dangerous if the tube is dislodged. Thus, these actions should not be taken before confirming the tube's position.
