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. Omit over-the-counter medications from the at-home medication list:
Over-the-counter medications should be included in the medication reconciliation process to provide a comprehensive overview of all medications the client is taking. These can have interactions or implications for the client's overall health.
B. Include medications the client received in the acute setting but will no longer need after transfer:
Medications that the client will no longer need after transfer should be excluded from the reconciliation list to avoid confusion and unnecessary continuation of those medications.
C. Compare the current list of medications to medications the client will receive after transfer:
This is part of the medication reconciliation process. It is important to ensure continuity of care by comparing the current list of medications with the medications the client will receive after transfer. Any discrepancies or changes should be addressed.
D. Remove duplicate medications of different dosages from the reconciliation list:
This is the correct answer. Duplicate medications with different dosages can lead to confusion and errors. The reconciliation process involves identifying and resolving discrepancies, including duplicates, to ensure accuracy and safety in medication administration
Correct Answer is B
Explanation
A. BUN 15 mg/dL (Blood Urea Nitrogen):
BUN is a measure of kidney function, and an elevated BUN may suggest impaired kidney function. However, it is not a specific marker for azathioprine adverse effects.
B. WBC 3,000/mm² (White Blood Cell count):
This is the correct answer. Azathioprine can suppress bone marrow function, leading to leukopenia (low white blood cell count). A WBC count of 3,000/mm² indicates a lower-than-normal white blood cell count, which can increase the risk of infection.
C. Hct 45% (Hematocrit):
Hematocrit measures the percentage of red blood cells in the blood. While it can be affected by various factors, it is not a specific marker for azathioprine adverse effects.
D. Platelets 250,000/mm²:
Platelets are involved in blood clotting, and a platelet count of 250,000/mm² is within the normal range. Azathioprine is not typically associated with adverse effects on platelet counts.
