Correct Answer: C

Rationale: Lentils are an excellent source of protein, suitable for a vegan diet, and promote wound healing. Brown rice (Choice A) is a carbohydrate-rich food and lacks sufficient protein for wound healing. Pureed avocado (Choice B) is a healthy fat source but low in protein. Orange juice (Choice D) is a source of vitamin C but lacks protein needed for wound healing.

Correct Answer: C

Rationale: An elevated creatinine level indicates potential kidney dysfunction, which is crucial when administering gentamicin as it can be nephrotoxic. Reporting a high creatinine level to the provider is essential to prevent further kidney damage. Choice A (Hematocrit 45%) is within the normal range and not directly related to gentamicin administration. Choice B (Sodium 140 mEq/L) and Choice D (Potassium 4.0 mEq/L) are also within normal limits and do not directly impact the administration of gentamicin.

Correct Answer: C

Rationale: The correct answer is C, Oxybutynin. Oxybutynin can worsen urinary retention, so the nurse should verify this prescription with the provider. Trimethoprim-sulfamethoxazole (Choice A) is a common antibiotic used to treat UTIs and does not require verification. Hyoscyamine (Choice B) is an anticholinergic medication used for bladder spasms and does not typically worsen UTI symptoms. Phenazopyridine (Choice D) is a urinary analgesic that helps relieve pain, burning, and discomfort caused by a UTI, which may not necessarily require verification in this scenario.

Correct Answer: C

Rationale: The correct answer is C because taking two medications together helps prevent the development of drug resistance in HIV treatment. Choice A is incorrect because the primary goal of combination therapy is not necessarily a faster recovery. Choice B is incorrect as the main purpose of combining medications in HIV treatment is to prevent resistance rather than improving the immune system. Choice D is incorrect because while it is true that the medications may target different parts of the virus, the main reason for using both together is to prevent resistance.

Correct Answer: B

Rationale: After a flexible bronchoscopy, it is essential to withhold food and liquids until the client's gag reflex returns. This precaution helps prevent aspiration, as the gag reflex protects the airway from foreign material. Irrigating the client's throat every 4 hours (Choice A) is unnecessary and may increase the risk of aspiration. Suctioning the client's oropharynx frequently (Choice C) can cause trauma and is not indicated unless there is a specific medical reason for it. Having the client refrain from talking for 24 hours (Choice D) is not necessary after a flexible bronchoscopy.
