Prescribed is 750 mL of IV fluids to infuse in 10 hours. What rate should the nurse program the IV infusion pump for?
The Correct Answer is ["75"]
To calculate the rate of IV infusion, the nurse should divide the volume of fluid by the time in hours.
In this case, 750 mL divided by 10 hours equals 75 mL per hour.
Therefore, the nurse should program the IV infusion pump for 75 mL per hour.

Correct Answer is C
Explanation
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 B
Explanation
A. Butorphanol
Butorphanol is a mixed opioid agonist-antagonist. It has both agonist and antagonist properties at opioid receptors. While it can be used for pain management, it is not commonly used for opioid overdose reversal.
B. Naloxone
Naloxone is an opioid receptor antagonist and is the drug of choice for reversing opioid overdose, including morphine overdose. It works by competitively binding to opioid receptors, blocking the effects of opioids.
C. Flumazenil
Flumazenil is a selective antagonist for benzodiazepines. It is used to reverse the effects of benzodiazepine overdose but does not have an effect on opioid overdose.
D. Pentazocine
Pentazocine is a mixed opioid agonist-antagonist. Like butorphanol, it has both agonist and antagonist properties at opioid receptors. It is used for pain management but is not commonly used for opioid overdose reversal.
