Correct Answer: A

Rationale: The correct answer is to instruct the client to walk 15 to 20 minutes three times a day. Walking is beneficial as it helps improve circulation and reduces the risk of complications following sclerotherapy. Choice B is incorrect because keeping the legs in the dependent position when sitting can lead to increased venous pressure, worsening varicose veins. Choice C is incorrect as compression bandages should typically be worn continuously, especially during the initial healing phase. Choice D is incorrect as Berger-Allen exercises are not commonly associated with post-sclerotherapy care.

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: B

Rationale: The correct answer is B. Weighing the client daily at the same time each day is the most accurate method for monitoring fluid balance. Changes in body weight can indicate fluid retention or loss. Measuring and recording fluid intake and output (choice A) is important but may not reflect total body fluid status accurately. Assessing vital signs (choice C) and checking the client's lungs for crackles (choice D) are important assessments but do not directly provide the most accurate monitoring of fluid status.

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: C

Rationale: In nursing care, implementation involves putting the nursing care plan into action. This step includes safeguarding the rights and privacy of the patient and their family by providing care in a respectful and confidential manner. Evaluation (A) is about assessing the effectiveness of the care provided. Planning (B) is the stage where specific interventions are designed. Assessment (D) is the initial step where data is collected to identify the patient's needs.
