Correct Answer: D

Rationale: In this scenario, the correct action is to apply a water-soluble lubricant to the lips, oral mucosa, and nares. This helps in keeping the mucous membranes moist, which is essential for a client with a dry mouth due to the nasogastric tube and oxygen therapy. Choice A, applying a petroleum-based lubricant to the lips, is not suitable as it may not be safe for internal use. Choice B, giving sips of water, is contraindicated as the client has a nasogastric tube in place for suction. Choice C, providing ice chips, is also not recommended as the client needs proper lubrication to address dryness, not cold stimulation.

Correct Answer: A

Rationale: Recognizing signs of infant dehydration is crucial for ensuring the health and well-being of infants. Dehydration can be life-threatening for infants if not addressed promptly. Proper diaper changing techniques, while important for hygiene, can be learned incrementally. The immunization schedule and breastfeeding positions are also essential topics, but identifying signs of dehydration takes precedence as it requires immediate attention to prevent serious complications.

Correct Answer: D

Rationale: The correct answer is D. Documentation of client education in the nursing record provides information on the implementation and progress of the educational program, which is crucial for evaluating its process. Choices A and B focus on individual client assessment rather than program evaluation. Choice C, community census data, is not directly related to evaluating the process of the prevention education program for older adults at risk for substance abuse.

Correct Answer: B

Rationale: Prioritizing the topic of how to childproof the home is crucial as it provides a holistic approach to safeguarding children from various injuries within the home environment. Childproofing the home addresses a wide range of hazards such as falls, burns, poisoning, and choking incidents. While topics like the benefits of car seats, the importance of helmet use, and ways to prevent drowning are important, childproofing the home covers a broader spectrum of safety measures that can significantly reduce the risk of injuries for children.

Correct Answer: A

Rationale: The correct answer is A, Graves' disease. The symptoms described in the client are classic manifestations of hyperthyroidism, which is commonly caused by Graves' disease, an autoimmune condition affecting the thyroid. Weight loss, racing heart rate, difficulty sleeping, moist skin with fine hair, prominent eyes, lid retraction, and a staring expression are all indicative of hyperthyroidism. Choice B, Cushing's syndrome, is characterized by weight gain, hypertension, and a rounded face due to excess cortisol. Choice C, Addison's disease, presents with symptoms such as weight loss, fatigue, and hyperpigmentation due to adrenal insufficiency. Choice D, hypothyroidism, typically features symptoms opposite to those described in the client, such as weight gain, bradycardia, and dry skin.
