Correct Answer: B

Rationale: The correct answer is B: "Have you had any unexplained weight loss?" Unexplained weight loss can be a significant symptom of various endocrine disorders, such as hyperthyroidism and diabetes. Weight changes are often closely linked to endocrine dysfunction due to the hormonal imbalances affecting metabolism. Choices A, C, and D are less specific to endocrine dysfunction. Pain in the legs, changes in bowel movements, and joint pain or discomfort are symptoms that can be related to various health conditions but are not as indicative of endocrine disorders as unexplained weight loss.

Correct Answer: A

Rationale: The correct answer is A: 'Managing patients' legal affairs.' Practical nurse management responsibilities are typically categorized into managing work center operations, managing personnel, and overseeing patient care. Legal affairs management is not a standard responsibility for practical nurse management. Choice B is incorrect as it introduces information about the hypothalamus, which is unrelated to the question. Choice C and D are both common areas of concern in practical nurse management, involving the operations of the work center and managing personnel, respectively.

Correct Answer: D

Rationale: In a sickle cell crisis, morphine is the preferred analgesic due to its potency and effectiveness in managing severe pain. Choice A is incorrect because aspirin is contraindicated in sickle cell disease due to its potential to cause a further decrease in blood flow. Choice B, Motrin (ibuprofen), is also not the ideal choice as NSAIDs can exacerbate renal complications in sickle cell patients. Choice C, Demerol (meperidine), is not recommended for sickle cell pain management due to its toxic metabolite accumulation which can cause seizures and other complications.

Correct Answer: C

Rationale: The correct answer is to wear extra warm clothing during cold exposure. This instruction is crucial for managing Raynaud's phenomenon as it helps prevent vasospasms triggered by cold temperatures. Choice A is incorrect because exacerbations can occur in any season. Choice B is not directly related to managing Raynaud's phenomenon. Choice D is also irrelevant as direct sunlight exposure does not typically worsen symptoms of Raynaud's phenomenon.

Correct Answer: C

Rationale: When conducting a Clinitest for testing urinary glucose levels, it is essential to add the correct amounts of urine and Clinitest reagent as instructed. Adding more water than urine could dilute the sample, leading to inaccurate test results. It's important to follow the correct ratio of drops specified in the instructions for an accurate reading. Choice A is incorrect as the specimen should be collected before meals for accurate results. Choice B is incorrect as it should be the Clinitest tablet, not the clingiest tablet. Choice D is incorrect as the statement is incomplete and lacks clarity.
