Calculate the infusion time for an IV of 1,500 mL running at 25 gtt/min. if the drop factor is 15 gtt/mL.

A. As requested by the patient.

Administering the drug only when requested by the patient may not provide adequate prophylaxis against chemotherapy-induced nausea and vomiting. These medications are often prescribed on a schedule to prevent symptoms rather than treating them reactively.

B. 1 hour after chemotherapy administration.

Waiting until 1 hour after chemotherapy administration may not cover the full period during which nausea and vomiting are likely to occur. The administration schedule for antiemetics is often more extended to provide better coverage.

C. The night before the treatment, the day of the treatment, and for 24 hours after the treatment.

This is the correct choice. Administering phenothiazine antiemetics according to this schedule helps ensure continuous coverage during the critical period when chemotherapy-induced nausea and vomiting are most likely to occur.

D. The day of treatment.

Administering the drug only on the day of treatment may not provide sufficient coverage for the entire duration when chemotherapy-induced nausea and vomiting can occur. Again, the schedule mentioned in option C is more comprehensive for prevention.

A. Avoid caffeine-containing beverages before sleep

The highest priority teaching point to help relieve sleeplessness would be to advise the client to avoid caffeine-containing beverages before sleep. Caffeine is a stimulant that can interfere with the ability to fall asleep and maintain a restful sleep.

B. Perform strenuous exercise before bedtime

Strenuous exercise close to bedtime can actually stimulate the body and make it more difficult for the individual to relax and fall asleep. It is generally recommended to engage in exercise earlier in the day.

C. Drink lots of fluids before bedtime

Drinking excessive fluids before bedtime may lead to disrupted sleep as it can increase the need to wake up for bathroom trips during the night. It's advisable to limit fluid intake close to bedtime.

D. Eat a heavy meal before bedtime

Consuming a heavy meal before bedtime can cause discomfort and indigestion, potentially disrupting sleep. It is recommended to have a light, easily digestible meal if eating close to bedtime.
