Correct Answer: C

Rationale: To reduce the risk of a needlestick injury, it is essential to keep a sharps container nearby where it can be easily accessed. This practice ensures quick and safe disposal of needles after use, minimizing the chances of accidental needlesticks. Recapping needles should be avoided as it increases the risk of injuries. Passing needles between workers should also be avoided to prevent accidental needle pricks during handovers. Therefore, the best practice to prevent needlestick injuries is to maintain a sharps container nearby for safe and immediate disposal of needles.

Correct Answer: C

Rationale: When a patient laughs due to anxiety during an EKG, it is likely to cause tachycardia, which is a rapid heart rate. This increased heart rate can lead to poor EKG graph quality as the electrical signals from large moving muscles can interfere with data collection from the chest leads. Therefore, in this scenario, the EKG is expected to show tachycardia with poor graph quality. Choices A, B, and D are incorrect because a patient laughing out of anxiety is more likely to result in an increased pulse rate (tachycardia) rather than a decreased pulse rate (bradycardia) or a normal EKG.

Correct Answer: C

Rationale: Denial is a defense mechanism where a patient rejects a reality that is too painful or difficult to accept. In the context of a terminal diagnosis, the patient may refuse to believe it in order to avoid facing the harsh truth. Regression (choice A) involves reverting to earlier, more childlike behaviors and is not applicable in this scenario. Mourning (choice B) is the process of grieving a loss, which typically occurs after acceptance of the diagnosis. Rationalization (choice D) is creating logical explanations to justify unacceptable behaviors, which is not the case when a patient denies a terminal diagnosis.

Correct Answer: C

Rationale: When assigning a floated nurse from another unit to a client in the emergency department, the goal is to choose a patient with minimal anticipated immediate complications. In this scenario, the adolescent with terminal cancer who has been on pain medications and presents with pinpoint pupils and a relaxed respiratory rate of 11 is the most stable option. These assessment findings indicate opioid toxicity, which, while serious, has the least risk of immediate complications compared to the other clients. Choice A involves a middle-aged client experiencing symptoms of possible cardiac issues due to diet pill overdose, which requires urgent intervention. Choice B presents a young adult with concerning symptoms of potential psychosis or substance withdrawal, requiring immediate attention. Choice D involves an elderly client who recently used crack, posing a high-risk situation that requires prompt evaluation and intervention. Therefore, the correct choice is the adolescent with opioid toxicity, as this client has the least immediate risk of complications among the options provided.

Correct Answer: C

Rationale: The correct answer is 'Please describe your symptoms.' This question is considered open-ended because it encourages the respondent to provide a detailed and descriptive answer, fostering a more elaborate response. Open-ended questions are designed to prompt thoughtful and detailed responses. Choice A is a closed-ended question since it seeks a specific time for the medication intake. Choice B is also closed-ended as it can be answered with a simple 'yes' or 'no,' limiting the response. Choice D is closed-ended as it requests a specific day for the follow-up appointment, restricting the range of possible responses.
