Correct Answer: B

Rationale: The correct answer is B because focusing on the patient's presenting situation is the first step in the problem-oriented approach. This allows the nurse to gather relevant data related to the current health issue, which is crucial for identifying the problem and formulating a care plan. Option A is incorrect as chronological order may not prioritize the most critical data. Option C is incorrect as interpretations come after data collection. Option D is incorrect as observation typically follows data collection and analysis. Focusing on the patient's presenting situation ensures efficient and effective data collection for problem-solving.

Correct Answer: C

Rationale: Correct Answer: C - ACTH Rationale: 1. ACTH (adrenocorticotropic hormone) can help control symptoms and induce remission in multiple sclerosis by reducing inflammation. 2. ACTH stimulates the production of cortisol, a natural anti-inflammatory hormone. 3. By reducing inflammation in the central nervous system, ACTH can help manage symptoms and promote remission. Summary of other choices: A: Acyclovir - Antiviral medication used to treat herpes infections, not effective for multiple sclerosis. B: Thyrotropin - Hormone that stimulates thyroid function, not used in the treatment of multiple sclerosis. D: Benadryl - Antihistamine used for allergies and itching, not indicated for multiple sclerosis management.

Correct Answer: A

Rationale: The correct answer is A: Prostate-specific antigen, which is used to screen for prostate cancer. PSA is a protein produced by the prostate gland, and elevated levels may indicate prostate cancer. Choice B is incorrect as PSA is specific to the prostate, not protein levels. Choice C is incorrect as pneumococcal strep antigen is related to pneumonia, not PSA. Choice D is incorrect as Papanicolua-specific antigen is not a recognized term, and PSA is not used to screen for cervical cancer.

Correct Answer: C

Rationale: The correct answer is C: Trunk. The thoracic cord supplies nerves to the trunk region of the body. The thoracic spinal nerves innervate the chest, abdomen, and back. They control sensation and movement in these areas. The head (A) is mainly supplied by cranial nerves, the pelvis (B) is innervated by lumbar and sacral nerves, and the coccyx (D) is supplied by the sacral nerves. Therefore, the correct answer is C as it aligns with the anatomical distribution of the thoracic spinal nerves.
