Correct Answer: B

Rationale: Male children are sexually abused nearly as often as female children. Perpetrators are usually men but can be women. Needs of male children who have been sexually abused might be different from the needs of female survivors. Male survivors might respond in anger, question their sexuality, use alcohol and other drugs, and might try to prove their masculinity by performing daring acts. It is crucial for the nurse to consider these potential outcomes, making choice B the correct answer. Choice A is incorrect because male victims of sexual abuse can indeed have long-term psychological problems, so the nurse should be aware of this issue. Choice C is incorrect as not all male sex abuse survivors grow up to abuse other children, which is a misconception. Choice D is incorrect because the needs of children who have been sexually abused can vary based on various factors, including gender, so it is important to consider individual differences.

Correct Answer: B

Rationale: A persistent cough might be related to an adverse reaction to captopril (Capoten). Tinnitus (choice A) and diarrhea (choice D) are not commonly associated adverse reactions of captopril. Muscle weakness (choice C) might occur initially but is not considered a common adverse effect of captopril. Therefore, the correct answer is B, persistent cough, as it is a known adverse reaction to captopril.

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: After a lung resection, such as the removal of the left lower lobe for lung cancer, closed chest drainage is a common post-operative measure to help drain any excess air or fluid from the chest cavity. A tracheostomy is not typically needed for this procedure, so choice B is incorrect. Similarly, a mediastinal tube is not routinely inserted following a left lower lobe lung resection, making choice C incorrect. Percussion vibration and drainage are not indicated for this type of surgery, so choice D is also incorrect. Therefore, the correct answer is closed chest drainage.

Correct Answer: C

Rationale: Medication bound to protein reduces the availability of the drug to produce desired medicinal effects because only unbound drugs can effectively bind to active receptor sites. When a drug is bound to protein, it cannot bind with receptor sites, limiting its therapeutic impact. Choice A is incorrect because drug availability is reduced when it is bound to protein. Choice B is incorrect as rapid distribution to receptor sites is not possible if the drug is bound to protein and cannot bind with receptors. Choice D is incorrect as metabolism does not increase when the drug is bound to protein; the liver first needs to separate the drug from the protein before metabolism can occur.
