Some drugs are excreted into bile and delivered to the intestines. Prior to elimination from the body, the drug might be absorbed. This process is known as:

Correct Answer: C

Rationale: The correct answer is 'enterohepatic cycling.' This process involves drugs being excreted into bile, delivered to the intestines, reabsorbed into the circulation, and can prolong the drug's presence in the body. 'Hepatic clearance' (Choice A) refers to the amount of drug eliminated by the liver. 'Total clearance' (Choice B) is the sum of all types of clearance including renal, hepatic, and respiratory. 'First-pass effect' (Choice D) is the amount of drug absorbed from the GI tract and metabolized by the liver before entering circulation, reducing the amount of drug available for systemic circulation.

Correct Answer: D

Rationale: Client education should be conducted by individuals with acknowledged expertise in the subject area and appropriate credentials to support their activities within the healthcare community. Choices A, B, and C involve reputable entities or professionals who can provide accurate and reliable client education. The American Heart Association, parish nurses, and home health care agencies are recognized for their healthcare-related knowledge and qualifications. However, unlicensed massage therapists lack the necessary qualifications and expertise to deliver appropriate healthcare-related education, making them unsuitable for referrals when it comes to client education in the community.

Correct Answer: C

Rationale: The correct answer is fidelity. Fidelity is the ethical principle that refers to keeping professional promises or obligations. Veracity, however, relates to truth-telling. Autonomy is about client self-determination and decision-making. Beneficence, on the other hand, involves doing good and is crucial in the provision of nursing care.

Correct Answer: B

Rationale: The primary goal of family education is to improve the quality of life. Family education aims to enhance the overall well-being and functioning of both the individual with the condition and their family members. While increased knowledge about mental illness may be a beneficial outcome, it is not the primary objective of family education. Symptom reduction is more commonly associated with psychoeducation rather than family education. Improving caregiving skills is a component of family education, but the primary focus is on improving the quality of life for everyone involved in the caregiving process.

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.
