1. What is the term for the tendency of a drug to combine with its receptor?

Correct answer: D

Rationale: The correct answer is 'affinity.' Affinity refers to the close relationship or mutual attraction between a drug and its receptor, indicating the strength of the drug-receptor bonding. Potency (Choice A) is related to the dose of a drug needed to produce a specific effect. Efficacy (Choice B) refers to a drug's ability to generate the desired effect. Kinetics (Choice C) deals with forces affecting the motion of material bodies or changes in a system, which is not directly associated with the bonding between a drug and its receptor.

2. All of the following tasks could be delegated to a nursing assistant or unlicensed assistive personnel (UAP) except:

Correct answer: A

Rationale: Monitoring an intravenous infusion involves assessing for complications, adjusting the flow rate, and monitoring the client's response, which requires the knowledge and skills of a licensed nurse (RN or LPN). Tasks that can be delegated to nursing assistants or unlicensed assistive personnel include assisting a client to the bathroom, offering fluids, and recording fluid intake. These activities are within the scope of practice for UAPs as they do not involve the specialized knowledge and training needed for intravenous infusion monitoring.

3. Which of the following lab values is associated with a decreased risk of cardiovascular disease?

Correct answer: B

Rationale: High HDL cholesterol is associated with a decreased risk of cardiovascular disease because HDL cholesterol is known as 'good' cholesterol. It helps remove other forms of cholesterol, like LDL cholesterol, from the bloodstream, reducing the risk of plaque buildup in the arteries. Low HDL cholesterol (Choice B) is actually a risk factor for cardiovascular disease because it means there is less of the 'good' cholesterol to perform its protective functions. Low total cholesterol (Choice C) and low triglycerides (Choice D) are not necessarily associated with a decreased risk of cardiovascular disease, as the balance and types of cholesterol play a more crucial role in heart health.

4. Which of the following are antiviral drug classes used in the treatment of HIV/AIDS?

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.

5. A client whose right leg is in skeletal traction complains of pain in the leg. Which action should the nurse take first?

Correct answer: C

Rationale: When a client in skeletal traction complains of pain, the priority action for the nurse is to realign the client. Severe pain may indicate the need for realignment or that the traction weights are too heavy. Realigning the client should be the initial response as it can help alleviate the pain by ensuring proper alignment. Asking the client to wiggle their toes may not address the underlying issue causing the pain. Removing traction weights should never be done unless specifically ordered by the healthcare provider as it can affect the traction's effectiveness. Medicating the client with analgesics should only be considered after attempting to address the cause of the pain, which in this case, is realignment.
