Correct Answer: A

Rationale: When questioning an elder about suspected abuse, the nurse should keep the questions nonjudgmental. This approach helps the elder feel safe and more willing to share information. Probing questions might be perceived as invasive, confrontational questions can lead to defensiveness and denial, and indirect questions may not elicit the necessary information, resulting in confusion or misinterpretation.

Correct Answer: B

Rationale: When a client reports hallucinations or delusions, it is crucial to respond in a non-confrontational and empathetic manner. Choice B acknowledges the client's fear without confirming the delusion, showing understanding, and providing reassurance. This response validates the client's feelings without reinforcing the false belief. The other responses in choices A, C, and D dismiss the client's feelings or perceptions, which can escalate the situation and harm the therapeutic relationship.

Correct Answer: C

Rationale: The correct answer is '"Her gums look too big for her teeth."?' Hyperplasia of the gums is a known side effect associated with Dilantin therapy. Option A, '"She is very irritable lately,"?' is not a typical side effect of Dilantin. Option B, '"She sleeps quite a bit of the time,"?' is a common side effect of Dilantin but not specific to gum hyperplasia. Option D, '"She has gained about 10 pounds in the last 6 months,"?' is not typically associated with Dilantin therapy and is unrelated to the question.

Correct Answer: A

Rationale: To infuse a 50 ml bolus in 30 minutes, the rate should be calculated as follows: 50 ml / 30 min = 100 ml per hour. Therefore, the correct answer is to set the pump rate at 100 ml per hour for one hour. Choice A is the correct rate based on the calculation. Choices B, C, and D all provide incorrect rates that do not match the physician's order. Choice B would only deliver 30 ml in 30 minutes, not the ordered 50 ml. Choice C would deliver 120 ml in one hour, which is 20 ml more than ordered. Choice D would only provide 25 ml over 30 minutes, not the full 50 ml prescribed.

Correct Answer: C

Rationale: The correct answer is 'enterohepatic cycling.' This process involves drugs being excreted into bile, delivered to the intestines, reabsorbed into the circulation, and can prolong the drug's presence in the body. 'Hepatic clearance' (Choice A) refers to the amount of drug eliminated by the liver. 'Total clearance' (Choice B) is the sum of all types of clearance including renal, hepatic, and respiratory. 'First-pass effect' (Choice D) is the amount of drug absorbed from the GI tract and metabolized by the liver before entering circulation, reducing the amount of drug available for systemic circulation.
