The nurse is assessing a patient who is receiving metoprolol 2 days after an acute coronary syndrome (ACS), Which physiological action of metoprolol supports the desired or therapeutic response?

Increases contractility.

Increases preload.

Decreases afterload.

Decreases diastolic filing time.

Answer and Explanation

The Correct Answer is C

A) Increases contractility: Metoprolol, a beta-blocker, actually decreases contractility. It reduces the force of contraction of the heart muscle, which can help reduce myocardial oxygen demand and improve outcomes after ACS. Increasing contractility would counteract the therapeutic goals of metoprolol in managing ACS.
B) Increases preload: Preload refers to the volume of blood in the ventricles at the end of diastole. Metoprolol does not increase preload; rather, it reduces myocardial workload and oxygen demand, which does not directly affect preload but rather the heart's performance overall.
C) Decreases afterload: Metoprolol reduces afterload indirectly by lowering blood pressure and decreasing heart rate, which helps reduce the workload on the heart. This reduction in afterload supports the therapeutic goals of metoprolol in managing ACS by decreasing the heart's work and improving cardiac efficiency.
D) Decreases diastolic filling time: Metoprolol slows the heart rate, which can lead to increased diastolic filling time, not a decrease. Increased filling time can be beneficial as it allows the heart more time to fill with blood between beats, thereby improving cardiac output.

Correct Answer is A

Explanation

A. Mix the capsule granules with water: Lansoprazole capsules contain granules that are typically not intended to be crushed or chewed. The appropriate method for administering these granules via an NGT is to mix them with water to ensure they are delivered properly. This approach aligns with the medication’s guidelines for administration through a tube.
B. Request the pharmacist to provide tablets: While tablets might be a suitable alternative, it is not the immediate action required if the client already has capsules. The focus should be on appropriately administering the prescribed form.
C. Open the capsule to crush the granules: Crushing or opening capsules is generally not recommended unless specifically instructed by the manufacturer or pharmacist. This can alter the drug’s effectiveness and release properties.
D. Sprinkle the granules in applesauce: Lansoprazole granules are not meant to be mixed with food like applesauce. They should be mixed with water to ensure proper dissolution and administration.

A. Withhold the medication until the client's breakfast tray is available on the unit. B. Consult with a pharmacist about scheduling the dose one hour after the client eats. C. Instruct the client that it is necessary to take nothing but water with the medication. D. Assign an unlicensed assistive personnel (UAP) to bring the client a glass of low fat milk.

Correct Answer is C

Explanation

A. Withhold the medication until the client’s breakfast tray is available on the unit: Withholding the medication until food is available is not necessary, as risedronate should be taken on an empty stomach to ensure proper absorption. Food can interfere with the medication's effectiveness.
B. Consult with a pharmacist about scheduling the dose one hour after the client eats: This option is not suitable as risedronate should be taken on an empty stomach, and delaying the dose until after eating would compromise the medication's effectiveness.
C. Instruct the client that it is necessary to take nothing but water with the medication: Risedronate must be taken on an empty stomach with a full glass of water and the client should remain upright for at least 30 minutes afterward. Milk or other beverages can interfere with the absorption of risedronate.
D. Assign an unlicensed assistive personnel (UAP) to bring the client a glass of low-fat milk: This is not appropriate, as risedronate should be taken with water only to ensure proper absorption. Milk can reduce the effectiveness of the medication.
