Correct Answer: C

Rationale: The correct answer is C because morning administration of prednisone mimics the body's natural corticosteroid secretion pattern. Cortisol, a natural corticosteroid, is typically highest in the morning and decreases throughout the day. By taking prednisone in the morning, the client aligns the drug's peak concentration with the body's natural cortisol levels, optimizing its therapeutic effects. Choice A is incorrect because while taking the drug at the same time daily is important for consistency, it does not specifically address the rationale for morning administration. Choice B is incorrect as the effectiveness of prednisone is not solely dependent on its half-life but also on alignment with the body's natural rhythm. Choice D is also incorrect as prednisone can be taken with food and does not necessarily require an empty stomach for optimal absorption.

Correct Answer: B

Rationale: The correct answer is B: Lung cancer. It causes the most deaths in women because it is often diagnosed at advanced stages when treatment options are limited. Breast cancer, although common, has a higher survival rate. Brain cancer is relatively rare compared to lung cancer. Colon and rectal cancer, while prevalent, do not surpass lung cancer in terms of mortality rates in women.

Correct Answer: C

Rationale: The correct answer is C. Wearing protective gear such as gown, mask, gloves, and goggles when entering the room is crucial to prevent infection in patients with AIDS. This intervention helps to minimize the risk of transmitting pathogens to the patient and vice versa. The protective gear acts as a barrier to prevent the spread of infectious agents. It also protects healthcare workers from exposure to potentially harmful pathogens. Prohibiting visitors who are severely immunodeficient (choice A) may be isolating for the patient and does not directly address preventing infection transmission. Prohibiting visitors with a cough (choice B) is important but does not cover all potential sources of infection. Ensuring protective barrier isolation precautions are in place (choice D) is a general statement and does not specify the practical steps needed to prevent infection transmission effectively.

Correct Answer: D

Rationale: The correct answer is D because antimetabolites interfere with the synthesis of nucleic acids (RNA and/or DNA), affecting multiple stages of RNA and DNA synthesis. This disruption hinders cell division and leads to cell death. Choices A and B are incorrect because antimetabolites do not specifically target cell division during the M phase or normal cellular processes during the S phase. Choice C is also incorrect because antimetabolites primarily target nucleic acid synthesis rather than altering the chemical structure of DNA or the binding between DNA molecules.

Correct Answer: A

Rationale: The correct answer is A: Moisture replacement. Sjogren's syndrome is an autoimmune disorder that primarily affects the moisture-producing glands, leading to dryness in the eyes, mouth, and other mucous membranes. Nursing care should focus on managing these symptoms by providing moisture replacement through artificial tears, lubricating eye drops, and hydrating mouthwashes. This helps prevent complications such as corneal damage and dental issues. Nutritional supplementation (B) may be needed if there are difficulties in eating due to dry mouth, but it is not the primary focus. Electrolyte balance (C) and arrhythmia management (D) are not directly related to the symptoms of Sjogren's syndrome and are therefore not the main priorities in nursing care for this condition.
