Correct Answer: B

Rationale: The correct answer is B: Preventing the onset of disease. Health promotion activities aim to prevent illnesses and promote overall well-being through education, lifestyle changes, and preventive measures. Choice A is incorrect as health promotion is not primarily about treating existing health conditions but rather preventing them. Choice C is incorrect because palliative care focuses on providing relief and comfort to patients with serious illnesses, not on preventing diseases. Choice D is also incorrect as conducting clinical trials is a research activity to test new treatments or interventions, not a focus of health promotion.

Correct Answer: A

Rationale: The correct answer is A: Hepatotoxicity. Isoniazid (INH) can lead to hepatotoxicity, necessitating the monitoring of liver function tests. This adverse effect is characterized by liver damage and dysfunction. Choices B, C, and D are incorrect because isoniazid is not typically associated with hyperglycemia, hypotension, or hypokalemia. Therefore, the nurse should focus on assessing for signs and symptoms of hepatotoxicity in a client receiving isoniazid.

Correct Answer: C

Rationale: Tertiary care is the correct answer because it involves specialized care provided by medical centers and regional or provincial hospitals. Primary care (Choice B) refers to basic healthcare services usually delivered by general practitioners, nurses, and other healthcare professionals. Secondary care (Choice A) involves specialized services provided by medical specialists and other health professionals who generally do not have first contact with patients. Intermediate care (Choice D) is not a recognized level of care in the typical healthcare system hierarchy; it may cause confusion as it's not a standard term used to describe levels of care.

Correct Answer: B

Rationale: An occupational therapist is the most appropriate professional to refer the client to in this situation. Occupational therapists can provide assistance with techniques and tools to help the client manage insulin administration despite arthritis. Referring the client to a social worker (Choice A) may not directly address the client's difficulty with insulin. While physical therapists (Choice C) focus on mobility and strength, they may not specialize in techniques for insulin administration. Referring the client to another client with diabetes (Choice D) is not a professional or appropriate solution to address the client's difficulty.

Correct Answer: C

Rationale: In community health nursing practice, nurses are trained as generalists in nursing. They receive education that equips them to address a wide range of health concerns in the community. Choice A, nurse-midwife, is incorrect as it refers to a specific role focusing on childbirth and maternal health. Choice B, practice nursing, is vague and does not specifically describe the training of community health nurses. Choice D, midwife, is also incorrect as it refers to a specialized role in maternal and newborn care, different from the generalist training of community health nurses.
