The nurse is administering the angiotensin II receptor antagonist valsartan. Which physiological response causes its therapeutic effect?

Chronotropic effect.

Diuresis

Vasodilation.

Sympatholytic action.

Answer and Explanation

The Correct Answer is C

A) Chronotropic effect: This term refers to changes in heart rate. Angiotensin II receptor antagonists like valsartan primarily affect blood pressure and vascular tone, rather than directly altering heart rate.
B) Diuresis: Diuresis involves increased urine production. Although some antihypertensives can have a diuretic effect, valsartan primarily works through mechanisms other than increasing urine output.
C) Vasodilation: Angiotensin II receptor antagonists such as valsartan work by blocking the action of angiotensin II, which leads to vasodilation. This reduction in vascular resistance helps to lower blood pressure and is the primary therapeutic effect of valsartan.
D) Sympatholytic action: This refers to the suppression of sympathetic nervous system activity. Valsartan does not primarily act through sympathetic nervous system modulation but rather through direct vasodilation by blocking angiotensin II receptors.

Correct Answer is A

Explanation

A. Ensure that the client eats breakfast: Regular insulin is a fast-acting insulin that typically begins to work within 30 minutes to an hour after administration, peaks around 2-3 hours, and can last for up to 6 hours. Therefore, it is crucial that the client eats a meal, such as breakfast, shortly after the insulin is administered to prevent hypoglycemia.
B. Provide a mid-afternoon snack for the client: While snacks may be necessary depending on the client's overall meal and insulin schedule, it is more critical to ensure the client eats the meal immediately following insulin administration to manage blood glucose levels.
C. Assess the client for hypoglycemia around 1500: While monitoring for hypoglycemia is important, it is more critical to ensure the client eats their meal soon after insulin administration to prevent hypoglycemia in the first place.
D. Perform a glucometer reading at 1000: A glucometer reading at 1000 might be useful for monitoring blood glucose levels but ensuring that the client eats a meal promptly is a more immediate and critical action following insulin administration.

A. Maintain a cool, calm room environment. B. Provide the client with a soft toothbrush. C. Allow the client ample rest periods. D. Keep the head of the bed elevated.

Correct Answer is B

Explanation

A) Maintain a cool, calm room environment: While a calm environment can be beneficial for overall patient well-being, it is not specifically related to the care of a client on clopidogrel. This instruction does not address the direct needs or precautions associated with clopidogrel use.
B) Provide the client with a soft toothbrush: Clopidogrel is an antiplatelet medication that increases the risk of bleeding. To minimize gum bleeding and oral mucosal damage, it is crucial to use a soft toothbrush to prevent injury. This measure helps to reduce the risk of bleeding complications associated with the medication.
C) Allow the client ample rest periods: While rest is important for overall health, it is not specifically related to the precautions needed for a client on clopidogrel. The primary concern with clopidogrel is managing bleeding risks rather than providing rest.
D) Keep the head of the bed elevated: Elevating the head of the bed is generally useful for managing certain conditions like respiratory issues or gastrointestinal reflux but does not directly relate to the specific needs of a client taking clopidogrel. The focus for clients on clopidogrel should be on preventing bleeding complications.
