Correct Answer: D

Rationale: When assessing a client's self-expectations about weight loss, it is crucial to inquire about what the client considers a realistic weekly weight loss goal. This question helps in understanding the client's perception and expectations regarding the weight loss journey, enabling the establishment of achievable goals. Choices A, B, and C do not directly address the aspect of setting realistic goals for weight loss. While questioning about changing eating habits, feelings about losing weight, or the importance of weight loss are relevant, they do not specifically focus on setting achievable goals, which is essential for effective weight management.

Correct Answer: A

Rationale: During suctioning, a vagal response can be triggered leading to bradycardia. It is crucial for the nurse to monitor for this potential dysrhythmia. Tachycardia (Choice B) is less likely during suctioning and is not the priority. Premature ventricular beats (Choice C) and heart block (Choice D) can occur but are less common compared to bradycardia in this situation.

Correct Answer: C

Rationale: The therapeutic index is the ratio between the median lethal dose and median effective dose of a drug, indicating the safety margin. Narrow therapeutic index medications have a small difference between minimum toxic levels and minimum effective concentration in the blood, making them high-risk drugs that require close monitoring to avoid toxicity. Choice A is incorrect because pharmacokinetics refer to drug absorption, distribution, metabolism, and elimination, not the therapeutic index. Choice B is incorrect because narrow therapeutic index drugs necessitate monitoring due to their narrow margin of safety. Choice D is incorrect because narrow therapeutic index drugs do not necessarily have limited potency but are characterized by a small window between efficacy and toxicity.

Correct Answer: A

Rationale: The correct answer is naloxone (Narcan). Naloxone is an opioid antagonist used to reverse opioid-induced respiratory depression and somnolence. In this scenario, the client's extreme somnolence and respiratory depression suggest an opioid overdose, making naloxone the appropriate choice to counteract these effects. Labetalol (Normodyne) is a nonselective beta-blocker used to treat hypertension, not opioid overdose. Neostigmine (Prostigmin) is a cholinesterase inhibitor used to reverse neuromuscular blockade, not opioid-induced respiratory depression. Thiothixene (Navane) is an antipsychotic medication used to treat schizophrenia and is not indicated for opioid overdose.
