Question

Alcohol Abuse Disorder Nurse Stacy is preparing to administer an intermittent IV bolus of ranitidine (Zantac) 50 mg in 0.9% sodium chloride 100 mL over 20 min. Stacy should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number.)

Answer 1

Stacy should set the IV pump to deliver 300 mL/hr for the intermittent IV bolus of ranitidine (Zantac) 50 mg in 100 mL of 0.9% sodium chloride over 20 minutes, ensuring precise administration.

Step-by-step explanation:

In administering an intermittent IV bolus of ranitidine (Zantac) at 50 mg in 100 mL of 0.9% sodium chloride over 20 minutes, the IV pump rate is crucial for accurate dosage.

The calculation involves dividing the total volume (100 mL) by the infusion time (20 minutes) and converting the result to hours. Therefore, 100 mL / 20 minutes equals 5 mL/min. To convert this to hours, multiply by 60, resulting in 300 mL/hr.

This calculated rate ensures a controlled and steady administration of ranitidine, allowing the patient to receive the prescribed dosage over the specified 20-minute timeframe.

Precision in IV pump settings is paramount to prevent under or overdosing, emphasizing the importance of accurate calculations in nursing practice.
