A nurse is preparing to administer 0.9% sodium chloride 1,000 mL IV to infuse over 4 hr. The drop factor on the manual tubing is 12 gtt/mL. The nurse should regulate the 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.)

Answer and Explanation

The Correct Answer is ["50"]

To calculate the flow rate in drops per minute (gtt/min), you can use the formula:

Flow rate (gtt/min) = Volume (mL) × Drop factor (gtt/mL) ÷ Time (min)

Given:
Volume = 1000 mL
Drop factor = 12 gtt/mL
Time = 4 hours

Convert 4 hours to minutes:
4 hours × 60 minutes/hour = 240 minutes

Then

Flow rate (gtt/min) = 1000 mL × 12 gtt/mL ÷ 240 min

Flow rate (gtt/min) = 12000 gtt ÷ 240 min

Flow rate (gtt/min) = 50 gtt/min

Therefore, the nurse should regulate the flow rate to deliver 50 gtt/min.

Correct Answer is ["6.5"]

Explanation

To answer this question, we need to perform some calculations. First, we need to convert the client's weight from pounds to kilograms. We can do this by dividing 143 by 2.2, which gives us 65 kg. Next, we need to multiply the dose of cyclosporine by the client's weight to get the total amount of medication needed. We can do this by multiplying 5 mg/kg by 65 kg, which gives us 325 mg. Finally, we need to divide the total amount of medication by the concentration of the injection to get the volume to administer. We can do this by dividing 325 mg by 50 mg/mL, which gives us 6.5 mL. Therefore, the nurse should administer 6.5 mL of cyclosporine injection to the client.

Correct Answer is ["1.5"]

Explanation

To calculate the amount of phenobarbital to administer per dose after the initial dose, the nurse should use the following formula:

mL = (dose in mg) / (concentration in mg/mL)

The dose in mg is 200 mg, and the concentration in mg/mL is 130 mg/mL. Plugging these values into the formula, we get:

mL = (200 mg) / (130 mg/mL)

mL = 1.5385

Rounding to the nearest tenth, the nurse should administer 1.5 mL per dose after the initial dose.
