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: 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: B

Rationale: The correct answer is B: Gastritis may cause bleeding. In patients with hiatal hernia, gastritis can occur due to the reflux of stomach acid into the esophagus. This gastritis can lead to gastrointestinal bleeding, resulting in anemia. Choice A is incorrect because iron absorption is not necessarily reduced in hiatal hernia. Choice C is incorrect as iron stores turnover rate is not directly related to the development of anemia in this context. Choice D is incorrect as an aversion to iron-rich foods is not a common reason for anemia in patients with hiatal hernia.

Correct Answer: B

Rationale: Weighing the client daily at the same time each day is the most accurate method for monitoring fluid balance. Changes in body weight can reflect fluid retention or loss. Measuring and recording fluid intake and output (Choice A) is important but may not provide immediate changes in fluid status. Assessing vital signs (Choice C) can offer some information but may not be as specific to fluid status as daily weighing. Checking the client's lungs for crackles (Choice D) is more related to assessing respiratory status rather than direct fluid monitoring.

Correct Answer: C

Rationale: The correct answer is C. Smoking, especially in clients over 30, increases the risk of thromboembolic events, making oral contraceptives contraindicated. Choice A (More than 30 years of age) is not a direct contraindication for oral contraceptives. Choice B (Had two multiple pregnancies) is not a factor that contraindicates the use of oral contraceptives. Choice D (Has a history of borderline hypertension) is not a specific contraindication for oral contraceptives unless it is severe or uncontrolled hypertension.
