A nurse is preparing to administer buspirone 7.5 mg PO every 12 hr to a client. The amount available is buspirone 15 mg/tablet. How many tablets should the nurse administer per dose?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

To calculate the infusion rate in mL/hr for total parenteral nutrition (TPN) we divide the total volume by the total infusion time.

Given: Total volume of TPN = 1800 mL Total infusion time = 24 hours

Infusion rate (mL/hr) = Total volume / Total infusion time

Substituting the given values: Infusion rate = 1800 mL / 24 hr ≈ 75 mL/hr

Rounded to the nearest whole number, the nurse should set the IV pump to deliver approximately 75 mL/hr of TPN.

B. Shake the container vigorously:

This is the correct action. Phenytoin suspension tends to settle over time, leading to non-uniform distribution of the medication in the suspension. Therefore, shaking the container vigorously before administering each dose ensures proper dispersion of the medication and helps maintain consistent drug concentration, thus promoting therapeutic efficacy.

A. Check the child's blood pressure:

Checking the child's blood pressure is not directly related to the administration of phenytoin suspension. Monitoring blood pressure may be indicated in certain clinical situations or with certain medications, but it is not specifically required before administering phenytoin suspension.

C. Be sure the child has not eaten within the hour:

While it's important to consider food-drug interactions with certain medications, such as those affected by food intake, there are no specific dietary restrictions associated with phenytoin suspension administration. Therefore, checking whether the child has eaten within the hour is not a necessary step before administering phenytoin suspension.

D. Perform mouth care:

Performing mouth care is not directly related to the administration of phenytoin suspension. However, oral hygiene is important for overall health, especially in children who may have difficulty performing adequate mouth care independently. While mouth care should be encouraged, it is not specifically required before administering phenytoin suspension.
