Correct Answer: D

Rationale: The correct answer is 'the neonatal and pediatric populations.' Syringe pumps are commonly used in neonatal and pediatric populations because they allow for precise infusion of small volumes of medications or fluids at controlled rates. This is crucial for ensuring safety and accuracy in these delicate populations. Choice A is incorrect because syringe pumps are not limited to obstetrics; they are used in various healthcare settings. Choices B and C are incorrect because syringe pumps are not typically used for dilute antibiotics or large volumes of IV solutions. Instead, they are preferred for delivering small volumes accurately, making them ideal for neonatal and pediatric care.

Correct Answer: A

Rationale: When an elderly client with cancer is receiving NSAID therapy, monitoring BUN (blood urea nitrogen) and creatinine levels is crucial. NSAIDs can cause renal toxicity, especially in the elderly. BUN and creatinine levels help assess renal function and detect early signs of renal impairment. Monitoring creatinine alone (Choice B) is not sufficient as BUN provides complementary information about renal function. Monitoring hemoglobin (Hgb) and hematocrit (Hct) (Choice C) is important for assessing anemia but not specific to NSAID therapy in the elderly. CFT (Choice D) is not a standard abbreviation in this context, and monitoring coagulation function is not directly related to NSAID therapy in this scenario.

Correct Answer: A

Rationale: When assessing a client's mobility status, it is crucial to start by examining their gait. Gait assessment is usually conducted as the client walks into the room. Normal gait is described as smooth, flowing, and rhythmic without the need for assistive devices. Choices B, C, and D are incorrect as they do not represent the standard practice of beginning the assessment of mobility status with gait examination.

Correct Answer: D

Rationale: The correct answer is 'All of the above.' Nucleoside reverse transcriptase inhibitors inhibit the enzyme reverse transcriptase, protease inhibitors block the activity of the HIV-1 protease enzyme, and HIV fusion inhibitors prevent HIV from entering human cells. Therefore, all the choices provided are valid antiviral drug classes for managing HIV/AIDS. Nucleoside reverse transcriptase inhibitors, protease inhibitors, and HIV fusion inhibitors play crucial roles in combating the virus at different stages. Nucleoside reverse transcriptase inhibitors target an early stage, protease inhibitors act on a later stage, and HIV fusion inhibitors prevent viral entry. Thus, 'All of the above' is the correct and comprehensive answer encompassing different mechanisms of action in managing HIV/AIDS.

Correct Answer: C

Rationale: Termination in the nurse-client relationship should first be addressed in the orientation phase. This is because the client has a right to know the parameters of the relationship from the beginning. During the orientation phase, it is important to discuss if the relationship is time-limited, inform the client about the number of sessions, or explain that it is open-ended with the termination date to be negotiated later. Addressing termination in the orientation phase helps establish transparency and clear communication. Choices A, B, and D are incorrect because termination discussions should ideally start at the beginning of the relationship to set appropriate expectations.
