Correct Answer: B

Rationale: The most effective intervention when working with clients who have a history of self-harm, like the client diagnosed with Borderline Personality Disorder, is to involve them actively in their treatment. By enlisting the client to define and describe the harmful behaviors, the client becomes an integral part of identifying triggers and understanding the underlying causes of their actions. This approach empowers the client, promotes self-awareness, and fosters a sense of control over their behaviors. Constantly observing the client (Choice A) may lead to a lack of trust and hinder the therapeutic relationship. Checking on the client every 15 minutes (Choice C) may disrupt the client's sense of autonomy and privacy. Removing all items from the environment that could be used for self-harm (Choice D) is a temporary solution and does not address the root causes of the behavior.

Correct Answer: C

Rationale: The correct answer is the kidney(s) because most drugs are excreted in the urine, either as the parent compound or as drug metabolites. The skin is not the primary organ for drug elimination; only a few drugs are excreted in sweat. The lung(s) primarily excrete volatile gases with expiration, not drugs. While the liver metabolizes drugs, it is the kidney(s) that primarily eliminate drugs through urine, especially those with a molecular weight above 300.

Correct Answer: C

Rationale: Estrogen antagonists are commonly used to treat estrogen hormone-dependent cancers such as breast carcinoma. One well-known estrogen antagonist used in breast cancer therapy is Tamoxifen (Nolvadex). This drug, in combination with surgery and other chemotherapeutic drugs, reduces breast cancer recurrence by 30%. Estrogen antagonists can also be administered to prevent breast cancer in women who have a strong family history. Thyroxine is a thyroid hormone used to treat hypothyroidism, not thyroid cancer. ACTH is an anterior pituitary hormone that stimulates the adrenal glands to release glucocorticoids; it does not treat adrenal cancer. Glucagon is a pancreatic alpha cell hormone that stimulates glycogenolysis and gluconeogenesis; it does not treat pancreatic cancer.

Correct Answer: D

Rationale: When a patient's central venous access device (CVAD) becomes infected, administering antibiotics through the line is essential to attempt to eliminate microorganisms within the catheter. The goal is to prevent the necessity of removing the catheter, which might be required if the infection persists. Choice A, 'To prevent infiltration of the peripheral line,' is incorrect as the priority is addressing the catheter infection, not preventing issues with a peripheral line. Choice B, 'To reduce the pain and discomfort associated with antibiotic administration in a small vein,' is not relevant to the rationale for choosing the CVAD for antibiotic administration. Choice C, 'To lessen the chance of an allergic reaction to the antibiotic,' is also incorrect as the main focus is managing the catheter-associated infection rather than allergy prevention.

Correct Answer: D

Rationale: A complication of a tonsillectomy is bleeding, and constant swallowing may indicate bleeding. Decreased appetite is expected after a tonsillectomy, as is a low-grade fever; thus, answers A and B are incorrect. Chest congestion, as mentioned in answer C, is not typical of tonsillectomy complications, making it an incorrect choice.
