Correct Answer: B

Rationale: The correct answer is B. Alendronate (Fosamax) should be taken with a full glass of water in the morning to prevent esophageal irritation and ensure proper absorption. Choice A is incorrect because taking alendronate at bedtime increases the risk of esophageal irritation due to lying down. Choice C is incorrect because patients should remain upright for at least 30 minutes after taking alendronate to prevent esophageal irritation. Choice D is incorrect because alendronate should be taken on an empty stomach, not with food, to enhance absorption.

Correct Answer: B

Rationale: The correct recommendation for a client with dry, peeling skin at a radiation therapy treatment site is to use mild soap and water to cleanse the area. This approach helps in preventing skin irritation and reduces the risk of infection. Applying lotion (Choice A) may further irritate the skin due to the chemicals present in the lotion. Covering the area with a sterile dressing (Choice C) is not necessary unless there is an open wound that needs protection. Allowing the skin to air dry after washing (Choice D) may lead to further dryness and peeling.

Correct Answer: A

Rationale: Lacerations, especially deep ones, are prone to bacterial contamination and may require immediate intervention to prevent infection. Abrasions, contusions, and ulcerations are not as likely to lead to immediate serious complications like infections as lacerations.

Correct Answer: D

Rationale: The correct intervention for a 5-week-old infant with hypertrophic pyloric stenosis presenting with projectile vomiting is to maintain intravenous fluid therapy. This is essential to maintain hydration before surgery. Instructing the mother to give sugar water only (Choice A) is inadequate and does not address the need for proper hydration. Offering oral rehydration every 2 hours (Choice B) may not be effective in cases of severe vomiting and could lead to further fluid loss. Providing Pedialyte feedings via nasogastric tube (Choice C) is an option, but in severe cases, intravenous fluid therapy is more effective in ensuring hydration and electrolyte balance.

Correct Answer: D

Rationale: The correct answer is D: 'Use sunscreen to prevent photosensitivity.' Methotrexate increases photosensitivity, so clients should be advised to use sunscreen to protect their skin from sun exposure. Choice A is incorrect because methotrexate is usually taken with food to reduce gastrointestinal side effects. Choice B may be important but is not specific to methotrexate therapy. Choice C is also important, but the primary reason for folic acid supplementation with methotrexate is to reduce the risk of certain side effects like anemia rather than preventing anemia itself.
