nurse is preparing to administer pantoprazole 80 by intermittent IV bolus every 12h. dium chloride (0.9%NaCl) 100 to infuse over 15min. The nurse should set the IV pump arest whole number. Use a leading zero if it applies. Do not use a trailing zero.
The Correct Answer and Explanation is:
To calculate the IV pump rate:
Given:
- Medication: Pantoprazole 80 mg
- Diluent: 100 mL of 0.9% Sodium Chloride (NaCl)
- Time: Infuse over 15 minutes
- Route: Intermittent IV bolus (IVPB)
- Need to set IV pump in mL/hr
Step-by-step calculation:
Step 1: Use the formula
$$
\text{IV pump rate (mL/hr)} = \left( \frac{\text{Volume (mL)}}{\text{Time (min)}} \right) \times 60
$$
$$
= \left( \frac{100\ \text{mL}}{15\ \text{min}} \right) \times 60
$$
$$
= 6.67\ \text{mL/min} \times 60 = 400\ \text{mL/hr}
$$
✅ Correct Answer: 400
Explanation (300+ words):
Pantoprazole is a proton pump inhibitor (PPI) commonly administered to manage conditions such as GERD, peptic ulcers, and Zollinger-Ellison syndrome. When given via IV, it is usually diluted in a compatible solution like 0.9% sodium chloride and administered over a specific time period to ensure safe and effective delivery while minimizing potential side effects, such as phlebitis or irritation at the infusion site.
In this scenario, the nurse is instructed to administer 80 mg of pantoprazole diluted in 100 mL of 0.9% NaCl over 15 minutes. Since the IV pump administers fluid in mL per hour, a conversion is necessary.
The key formula used here is:
$$
\text{Rate (mL/hr)} = \left( \frac{\text{Total Volume}}{\text{Minutes}} \right) \times 60
$$
The nurse calculates:
$$
\left( \frac{100\ \text{mL}}{15\ \text{min}} \right) \times 60 = 400\ \text{mL/hr}
$$
This result is rounded to the nearest whole number, which is 400. Importantly, this rate ensures the full 100 mL is delivered exactly over 15 minutes.
The instruction also notes to use a leading zero if it applies, such as 0.5 (not .5), and not to use a trailing zero, such as 1.0, because doing so can lead to medication errors. These are part of safe medication practices set by the Joint Commission and other nursing standards.
Understanding these calculations ensures safe drug delivery, prevents overdosing or underdosing, and reflects core nursing competencies in pharmacology and IV therapy.
