A patient is ordered a phenothiazine antiemetic for treatment of nausea and vomiting associated with chemotherapy. The nurse will be evaluating for a positive effect. At what time should the nurse administer the drug?
as requested by the patient.
1 hour after chemotherapy administration.
The night before the treatment, the day of the treatment, and for 24 hours after the treatment.
the day of treatment.
The Correct Answer is C
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.

Correct Answer is ["125"]
Explanation
`To calculate the rate of infusion in mL/h, you need to divide the total volume of fluid by the total time of infusion.
In this case, you have 1,000 mL of normal saline (NS) to infuse in eight hours.
Therefore, the rate of infusion is 1,000 mL / 8 h = 125 mL/h.
Correct Answer is B
Explanation
A. "It will help your baby gain weight faster."
This statement is not accurate. Caffeine citrate is not given to help with weight gain; its primary use is to stimulate the respiratory center in preterm infants and improve breathing.
B. "Caffeine can help your baby breathe better."
This is the correct response. Caffeine citrate is commonly used in premature infants to stimulate the respiratory center, leading to improved breathing. It is a standard treatment to reduce the risk of apnea of prematurity.
C. "This isn't the same substance that is in coffee."
While caffeine citrate is derived from caffeine, this statement might be confusing and does not directly address the specific benefits of caffeine citrate for preterm infants.
D. "The baby's temperature will be warmer with caffeine."
This statement is not accurate. Caffeine citrate is not used to affect the baby's temperature; its primary effect is on the respiratory system.
