A nurse is preparing to administer cimetidine 300 mg IV over 15 min to a client. Available is cimetidine 300 mg/100 mL of 0.9% sodium chloride. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Done use a trailing zero.)
The Correct Answer is ["400"]
Step 1: Determine the Total Volume Needed
- Supplied concentration: 300 mg/100 mL
- Prescribed dose: 300 mg
- Total volume needed = 100 mL
Step 2: Convert Time to Hours
- Prescribed infusion time = 15 minutes
- 15 minutes ÷ 60 minutes/hour = 0.25 hours
Step 3: Calculate the Infusion Rate (mL/hr)
- Infusion rate = Total volume (mL) ÷ Time (hours)
- Infusion rate = 100 mL ÷ 0.25 hours
- Infusion rate = 400 mL/hr
The nurse should set the IV pump to deliver cimetidine at 400 mL/hr (rounded to the nearest whole number).

Correct Answer is D
Explanation
A. INR 1.0: The International Normalized Ratio (INR) is a measure of blood clotting. A value of 1.0 is within the normal range, so there is no immediate concern related to furosemide administration based on this INR value.
B. WBC count 8,000/mm³: The white blood cell count is not directly related to furosemide administration, and the value of 8,000/mm³ is within the normal range. There is no immediate concern based on this WBC count.
C. Sodium 141 mEq/L: The sodium level is within the normal range, and it is not a contraindication for furosemide administration.
D. Potassium 2.5 mEq/L: A potassium level of 2.5 mEq/L is significantly below the normal range. Furosemide is a loop diuretic that can lead to potassium loss, and administering it when the potassium level is already low can further decrease potassium levels, potentially leading to serious complications such as cardiac arrhythmias. Therefore, the nurse should withhold the medication and contact the provider to address the low potassium level before administering furosemide.
Correct Answer is D
Explanation
A. Inform the client there is a prescription available if needed:
This response does not address the urgency indicated by the prescription stating "NOW." It is essential to take immediate action when the prescription indicates an urgent administration.
B. Notify the pharmacy to send the medication immediately:
While timely medication administration is crucial, contacting the pharmacy directly without clarification from the provider may lead to misinterpretation or errors. It's important to confirm the prescription details first.
C. Administer the medication within 90 minutes:
The prescription indicating "NOW" suggests a need for more immediate administration than within 90 minutes. Waiting for 90 minutes may not be in line with the urgency implied by the prescription.
D. Contact the provider to clarify the prescription:
This is the correct action. The prescription is ambiguous, and the nurse should seek clarification from the provider regarding the urgency of administration, the reason for the medication, and any other pertinent details to ensure safe and appropriate care.
