Correct Answer: A

Rationale: Victims of domestic violence are often correct at predicting their risk of harm. It is crucial for the nurse to ensure that the client is expressing herself authentically and not downplaying any potential danger. While victims can be insightful about their risk, it's essential to involve proper authorities, such as the police, in situations of intimate partner violence to ensure safety and provide necessary support. Choice B is incorrect because victims may not necessarily overestimate their safety risk. Choice C is incorrect as not all victims are in a state of denial; some may recognize the dangers they face. Choice D is incorrect because victims may not believe that keeping peace with their partner is the best way to prevent future attacks, as each individual's situation and mindset vary.

Correct Answer: D

Rationale: Quinidine can cause widened Q-T intervals and heart block, leading to a prolonged QT interval on the ECG. Other signs of myocardial toxicity associated with quinidine include notched P waves and widened QRS complexes. Common side effects of quinidine include diarrhea, nausea, and vomiting, while less common effects may include tinnitus, vertigo, headache, visual disturbances, and confusion. Monitoring for a prolonged QT interval is crucial due to the potential risk of serious arrhythmias. Choices A, B, and C are not typically associated with the use of quinidine and are therefore incorrect in this context.

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. Choice A is incorrect because male victims of sexual abuse can indeed have long-term psychological problems. Choice C is incorrect as not all male sex abuse survivors grow up to abuse other children. Choice D is incorrect as the needs of sexually abused children can vary based on gender and individual circumstances.

Correct Answer: A

Rationale: The correct answer is 0.9% sodium chloride. Normal saline is 0.9% sodium chloride, which has the same osmolarity as blood and does not cause cell lysis. Choices 2 and 3, 5% dextrose in water solution and sterile water, are hypotonic solutions that can lead to cell lysis. Choice 4, Heparin sodium, is an anticoagulant and is not routinely used to flush an IV device before and after the administration of blood.

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.
