Correct Answer: B

Rationale: The correct action for the nurse to take when finding that the TPN solution is infusing too rapidly is to stop the TPN infusion. This is crucial to prevent fluid overload and ensure the client's safety. Sitting the client upright (Choice A) or turning the client on their left side (Choice C) are not appropriate responses to a rapidly infusing TPN solution and do not address the immediate issue of preventing complications from the rapid infusion. Adding insulin to the TPN infusion (Choice D) is not indicated unless specifically prescribed by the healthcare provider for the client's condition. Therefore, the priority action is to stop the TPN infusion to prevent potential harm.

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: C

Rationale: The correct action in the medication reconciliation process is to compare prescriptions with the client's medications. This step ensures that there are no conflicting medications prescribed, reducing the risk of adverse drug interactions. Discontinuing current medications or writing new prescriptions without comparing them can lead to errors and potential harm. Asking the client to decide is not appropriate in this context as it is the nurse's responsibility to ensure medication safety based on professional judgment and knowledge.

Correct Answer: D

Rationale: The correct answer is D: Tachycardia, hypotension, and decreased urine output are classic clinical manifestations of hypovolemic shock. In hypovolemic shock, the body tries to compensate for low blood volume by increasing the heart rate (tachycardia) to maintain cardiac output, leading to hypotension and decreased urine output. Prompt fluid replacement is necessary to restore intravascular volume. Choices A, B, and C are incorrect because they do not represent the typical manifestations of hypovolemic shock.
