Correct Answer: D

Rationale: Administering analgesics on a scheduled basis for the first 24 hours is crucial in managing postoperative pain for the child. This helps control pain levels effectively, promoting comfort and aiding in the recovery process. Offering small amounts of clear liquids 6 hours following surgery may not be appropriate as the child may need time to recover from anesthesia. Giving cromolyn nebulizer solution every 6 hours is not indicated for postoperative care following appendicitis surgery. Applying a warm compress every 4 hours to the operative site may not be recommended as it can potentially interfere with the surgical wound healing process.

Correct Answer: D

Rationale: The correct answer is D. Calf pain on dorsiflexion following knee surgery may indicate a complication such as deep vein thrombosis, which is a serious condition requiring medical attention. Reporting this finding promptly is crucial to prevent further complications. Choices A, B, and C are within normal range for a client post knee surgery and do not typically indicate immediate complications that require urgent reporting.

Correct Answer: D

Rationale: The correct answer is D: Aspartate aminotransferase (AST) 60 units/L. An elevated AST level indicates liver damage, which can be a side effect of methotrexate and should be reported. Elevated white blood cell count (choice A), platelet count (choice B), or normal hemoglobin level (choice C) are not directly related to methotrexate therapy for rheumatoid arthritis.

Correct Answer: C

Rationale: The correct statement the nurse should include is to advise the client to empty their bladder after intercourse to help prevent UTIs. Emptying the bladder after intercourse helps reduce the risk of UTIs by flushing bacteria from the urethra. Choice A is incorrect as drinking water before and after intercourse is not specifically related to preventing UTIs. Choice B is incorrect as there is no direct correlation between orange juice consumption and UTI risk. Choice D is incorrect as taking a hot bath can actually increase the risk of UTIs by promoting bacterial growth.

Correct Answer: B

Rationale: The correct answer is B. Levothyroxine should be taken every morning before breakfast to enhance absorption and maintain consistent thyroid hormone levels. Option A is incorrect because levothyroxine should be taken on an empty stomach. Option C is incorrect because chest pain is not a common side effect of levothyroxine and stopping the medication abruptly can be harmful. Option D is incorrect because taking levothyroxine at bedtime may result in decreased absorption due to interactions with food and other medications.
