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: The correct response is 'Tell me more about your feelings on this issue.' This answer is the most therapeutic as it encourages the client to express his emotions and concerns, fostering a supportive and open dialogue between the client and the nurse. Option A may come across as dismissive and does not directly address the client's emotional state. Option B, while positive, oversimplifies the client's complex feelings. Option C focuses only on physical appearance, missing the opportunity to delve deeper into the client's emotional well-being. Therefore, the most therapeutic response is to encourage further discussion about the client's feelings.

Correct Answer: A

Rationale: The transplacental transfer of maternal antibodies supplements the infant's weak response to infection until approximately 3 to 4 months of age. While the infant starts producing immunoglobulin (Ig) soon after birth, it only reaches about 60% of the adult IgG level, 75% of the adult IgM level, and 20% of the adult IgA level by 1 year of age. Breast milk provides additional IgA protection. Although the immune system matures during infancy, full protection against infections is not achieved until early childhood, putting the infant at risk for infections. Choice B is incorrect because maternal antibody protection typically lasts around 3 to 4 months, not until the infant is 12 months old. Choice C is incorrect as infants are not shielded from all infections due to their immature immune system. Choice D is incorrect because while breastfeeding offers extra protection, it does not guarantee complete immunity against infections.

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.

Correct Answer: A

Rationale: The correct answer is 'grief work facilitation' because it is a nursing intervention classification specifically designed to address disturbed body image in burn clients. The expected outcome of this intervention is grief resolution, which can help the client cope with the body image changes resulting from the burn. Choice B, 'vital signs monitoring,' is not the appropriate intervention for body image disturbance in burn clients. Vital signs monitoring is typically used for assessing physiological parameters like blood pressure, pulse rate, and temperature. Choice C, 'medication administration: skin,' is more focused on treating skin-related issues rather than addressing body image disturbance. It involves the administration of medications to promote skin healing and integrity. Choice D, 'anxiety reduction,' is aimed at managing anxiety in clients with major burns and is not specifically targeted at addressing body image disturbance. While anxiety may be a common emotional response to burns, the most appropriate intervention for body image disturbance in this scenario is 'grief work facilitation.'
