Correct Answer: D

Rationale: Correct. Effectively managing personnel is indeed the most crucial and difficult management skill required of a practical nurse. This skill involves supervising, motivating, and coordinating the work of other healthcare staff, ensuring optimal patient care. Choices A, B, and C are important tasks but do not necessarily involve the same level of complexity and interpersonal skills required for managing personnel in a healthcare setting.

Correct Answer: A

Rationale: The correct answer is A: Simple carbohydrates. Simple carbohydrates can cause rapid spikes in blood glucose levels, which can be problematic for patients with diabetes. These carbohydrates are quickly broken down and absorbed by the body, leading to sharp increases in blood sugar levels. In contrast, complex carbohydrates and fiber-rich carbohydrates are generally better choices for individuals with diabetes because they are digested more slowly, resulting in a more gradual rise in blood glucose levels. Choice B, complex carbohydrates, are a better option for diabetic patients compared to simple carbohydrates. Choice C, fiber-rich carbohydrates, can also be beneficial for individuals with diabetes as they help in regulating blood sugar levels. Choice D, all carbohydrates, is too broad of a statement as not all carbohydrates have the same impact on blood glucose levels.

Correct Answer: A

Rationale: Corrected Rationale: Insulinomas lead to excessive insulin production, causing hypoglycemia. Symptoms of hypoglycemia include nervousness, jitteriness, and diaphoresis. These symptoms result from the low blood sugar levels. Flushed skin, dry mouth, and tented skin turgor (choice B) are more indicative of dehydration. Polyuria, polydipsia, and polyphagia (choice C) are classic symptoms of diabetes mellitus, not insulinomas. Hypertension, tachycardia, and feeling hot (choice D) are not typical symptoms of insulinomas.

Correct Answer: D

Rationale: Enteral feedings are commonly utilized for patients experiencing acute exacerbations of Crohn's disease to provide necessary nutrition and rest the bowel. Choices A, B, and C are incorrect because enteral feedings are not typically indicated for acute cholecystitis, hepatic encephalopathy, or ulcerative colitis in remission.

Correct Answer: A

Rationale: The correct answer is to instruct the client to walk 15 to 20 minutes three times a day. Walking helps improve circulation and reduces the risk of complications following sclerotherapy. Choice B, keeping the legs in the dependent position when sitting, is incorrect as it can increase venous pressure. Choice C, removing compression bandages before going to bed, is incorrect as compression should be maintained as per healthcare provider's instructions. Choice D, performing Berger-Allen exercises four times a day, is incorrect as these exercises may not be specifically recommended post-sclerotherapy.
