Correct Answer: D

Rationale: The correct answer is D: Elevated temperature. Cocaine is a stimulant drug that can lead to increased body temperature. Hypotension (Choice A) is less likely as cocaine tends to elevate blood pressure. Memory loss (Choice B) and slurred speech (Choice C) are more commonly associated with depressant drugs rather than stimulant drugs like cocaine.

Correct Answer: A

Rationale: The correct answer is A: "I will avoid aspirin while taking this medication." Clients taking warfarin should avoid aspirin due to the increased risk of bleeding. Choice B is incorrect because increasing the intake of green leafy vegetables high in Vitamin K can interfere with the effects of warfarin. Choice C is incorrect because warfarin should not be taken with antacids as they can decrease its absorption. Choice D is incorrect because mild bruising is a common side effect of warfarin due to its anticoagulant properties.

Correct Answer: A

Rationale: The correct answer is A. When a client receives antibiotics 2 hours late, it constitutes a medication error, requiring the completion of an incident report. Choice B, a client vomiting within 20 minutes of taking medications, does not necessarily require an incident report unless it is suspected to be related to a medication error. Choice C, a client requesting a statin at a specific time, and choice D, a client asking for pain medication an hour early, are not incidents that mandate the completion of an incident report unless there are specific circumstances indicating otherwise.

Correct Answer: C

Rationale: The correct answer is C: Previous violent behavior. This is the best predictor of future violence as individuals who have a history of violent behavior are more likely to engage in violent acts in the future. While experiencing delusions and being male may contribute to an increased risk of violence in certain situations, they are not as strong predictors as a history of violence. Similarly, having a history of being in prison may indicate a higher likelihood of violence, but it is not as directly linked to future violent behavior as previous violent actions.
