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.

Rationale: Atherosclerosis is primarily caused by high blood cholesterol, high blood pressure, and cigarette smoking. These factors contribute to the buildup of plaque in the arteries.

Rationale: The correct answer is C: Increased fiber intake. A diet high in fiber is beneficial for patients with hypertension as it helps lower blood pressure. Increasing fiber intake can aid in managing hypertension by promoting heart health and overall well-being. Choices A, B, and D are incorrect. Increased sodium intake is not recommended for hypertension as it can elevate blood pressure. Decreasing potassium intake is also not advised as potassium is essential for regulating blood pressure. Lastly, increasing cholesterol intake is detrimental for hypertension as it can contribute to cardiovascular issues and worsen the condition.

Magnesium sulfate can depress the central nervous system and decrease deep tendon reflexes, so monitoring them is crucial. Assessing arterial blood gases, skin turgor, or capillary refill time is not directly related to the administration of magnesium sulfate in this scenario.
