A nurse is preparing to administer lactated Ringer's IV to infuse at 60 mL/hr. The drop factor on the manual IV tubing is 60 gtt/mL. The nurse should set the IV flow rate to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["60"]
To calculate the IV flow rate in gtt/min, you can use the following formula:
Flow rate (gtt/min) = (Volume to be infused (mL) x Drop factor) / Time (min)
In this case, the volume to be infused is 60 mL/hr, the drop factor is 60 gtt/mL, and we want to find the flow rate in gtt/min.
Flow rate (gtt/min) = (60 mL/hr x 60 gtt/mL) / 60 min
Flow rate (gtt/min) = (3600 gtt/hr) / 60 min
Flow rate (gtt/min) = 60 gtt/min

Explanation
To calculate the dose of metronidazole for a client who weighs 212 lb, the nurse needs to convert the weight to kilograms and multiply it by the prescribed dose of 7.5 mg/kg.
One kilogram is equal to 2.2 lb, so the client's weight in kilograms is 212/2.2 = 96.36 kg. The dose of metronidazole in milligrams is 96.36 x 7.5 = 722.7 mg.
The nurse needs to find out how many mL of the available solution contain this amount of metronidazole.
The available solution has a concentration of 500 mg/100 mL, so the nurse can use a proportion to solve for the volume: 500/100 = 722.7/x.
Cross-multiplying and solving for x gives x = 722.7 x 100 / 500 = 144.54 mL.
The nurse should round the answer to the nearest whole number, so the final answer is 145 mL.
The nurse should administer 145 mL of metronidazole via intermittent IV bolus to the client.
Correct Answer is ["150"]
Explanation
To calculate the IV pump rate, you need to divide the total volume (1,200 ml) by the total infusion time (8 hours). Here's the calculation:
IV Pump Rate (ml/hr) = Total Volume (ml) / Total Infusion Time (hr)
IV Pump Rate (ml/hr) = 1,200 ml / 8 hr
IV Pump Rate (ml/hr) = 150 ml/hr
So, the nurse should set the IV pump to deliver 150 ml/hr.
