Correct Answer: B

Rationale: Uric acid levels are commonly assessed in patients with gout. Gout is a type of arthritis caused by the buildup of uric acid crystals in the joints, leading to inflammation and pain. Monitoring uric acid levels helps in diagnosing and managing gout. Asthma, diverticulitis, and meningitis are not conditions where blood tests for uric acid levels are typically necessary. Asthma is a respiratory condition, diverticulitis involves inflammation of the digestive tract, and meningitis is an infection of the meninges in the brain and spinal cord.

Correct Answer: A

Rationale: The correct criteria for Medicare-reimbursable home care services include the client being homebound and requiring a skilled service, such as physical therapy, occupational therapy, speech therapy, nursing, or social work. Choice A is correct because it aligns with these requirements. Choice B is incorrect as immediate previous hospitalization is not a prerequisite for home care services. Choice C is incorrect as age alone does not determine eligibility for Medicare-reimbursable home care services. Choice D is incorrect as the requirement of nursing and social work support alone is not sufficient for Medicare-reimbursable home care services.

Correct Answer: D

Rationale: The most appropriate nursing diagnosis for Mrs. Peterson is 'Sleep Pattern Disturbances (related to chronic leg pain).' Mrs. Peterson's sleep issues are directly linked to her chronic leg pain, which is a result of her arthritis. This nursing diagnosis addresses the primary cause of her sleep disturbances and allows for interventions that focus on managing the pain to improve her sleep. Choices A, B, and C are incorrect. Choice A correctly identifies the relationship between sleep disturbances and chronic leg pain, addressing the root cause. Choice B is incorrect as it only focuses on fatigue and does not encompass the broader sleep issues. Choice C is not relevant as there is no indication that Mrs. Peterson lacks knowledge about sleep hygiene measures.

Correct Answer: D

Rationale: The nurse should stand about 6 feet from the source of the fire. Getting closer might put the nurse in danger. Choice A, 1 foot, is incorrect because it is too close to the fire and can expose the nurse to unnecessary risk. Choice B, 2 feet, is also too close to the fire and may lead to potential harm. Similarly, choice C, 4 feet, is not the ideal distance as it is still within the range of potential danger. The correct answer is D, 6 feet, which is a safe distance for the nurse to extinguish the fire effectively without risking personal safety.

Correct Answer: A

Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.
