The nurse is caring for a client prescribed IV heparin. The client is prescribed 18 units/kg/hr. The client weighs 111.8 kg (245.96 Ibs). The heparin is labeled with 25,000 units in 250 mL of D5W. How many mL/hr should this client receive? Fill in the blank. Round to the nearest whole number.
Correct Answer: 20 mL/hr
Rationale: Calculate dose: 18 units/kg/hr × 111.8 kg = 2012.4 units/hr. Flow rate: (2012.4 units/hr ÷ 25,000 units) × 250 mL = 20.12 mL/hr, rounded to 20 mL/hr.
The primary healthcare provider (PHCP) prescribes 150 mL of sterile water to be administered over one hour. The drop factor is 15 gtts/mL. How many drops per minute will the nurse set the flow rate at? Fill in the blank. Round your answer to the nearest whole number.
Correct Answer: 38 gtts/minute
Rationale: Calculate: (150 mL × 15 gtts/mL) ÷ 60 min = 2250 gtts ÷ 60 = 37.5 gtts/min, rounded to 38 gtts/min.
The primary healthcare provider (PHCP) prescribes 500 mg of intravenous (IV) metronidazole to be administered over thirty minutes. The pharmacy supplies the medication in a bag labeled 500 mg of metronidazole in 100 mL of 0.9% saline. How many mL/hour should the nurse administer to the client? Fill in the blank.
