Correct Answer: D

Rationale: In a client with AIDS and impaired gas exchange from a respiratory infection, pain when swallowing can indicate esophageal involvement, such as esophagitis or an esophageal infection like candidiasis. These conditions can significantly impact the client's ability to take in nutrition and medications, leading to complications like dehydration and malnutrition. Therefore, immediate intervention is required to address the underlying cause and prevent further complications. Elevated temperature (choice A) may indicate infection but does not directly address the impaired gas exchange. Generalized weakness (choice B) and diminished lung sounds (choice C) are concerning but do not directly relate to the immediate need for intervention in the context of esophageal involvement in a client with impaired gas exchange.

Correct Answer: D

Rationale: The correct answer is D. An elevated serum creatinine level indicates kidney damage, which significantly increases the risk of complications from hypertension. High blood pressure can damage the kidneys over time, leading to impaired kidney function. Choices A, B, and C do not directly correlate with increased risk of complications related to hypertension. Choice A focuses on obesity and overeating, Choice B on anemia and alcohol consumption, and Choice C on a diet high in sodium and nitrates, none of which are as directly related to hypertension complications as kidney damage.

Correct Answer: B

Rationale: The correct guidance the nurse should provide is that sexually active females must use contraception while taking Accutane and for 1 month after the 20 weeks it is prescribed. Choice A is incorrect because Accutane is typically taken for a longer duration than 10 weeks. Choice C is incorrect because Accutane does not lower hemoglobin levels quickly. Choice D is incorrect as Accutane is known for having many side effects, including the risk of birth defects.

Correct Answer: B

Rationale: Placing the child on the affected side after a myringotomy facilitates ear drainage. This position helps prevent accumulation of fluids in the ear canal, aiding in the healing process. Placing the child in the supine position (Choice A) or on the unaffected side (Choice C) may not be as effective in promoting drainage. The Trendelenburg's position (Choice D) with the head lower than the body is used for conditions requiring increased venous return, not for post-myringotomy care.

Correct Answer: C

Rationale: The correct answer is C: 'Assist the child to develop effective communication.' Children with cerebral palsy often face challenges with communication skills. Therefore, priority nursing interventions aim to help them improve their communication abilities. Choice A is incorrect because while education is important, the priority for a child with cerebral palsy is to address immediate needs. Choice B is incorrect as toileting, although important, is not the priority in this case. Choice D is incorrect as ambulation may not be feasible or the most critical concern for a child with cerebral palsy.
