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 ["20.1"]

Explanation

To calculate the dosage of methylprednisolone, first convert the client's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds.

The client weighs 184 pounds, which is approximately 83.64 kilograms (184 lb / 2.2).

Next, multiply the client's weight in kilograms by the dosage prescribed, which is 30 mg/kg.

This results in a total dosage of 2509.2 mg (83.64 kg * 30 mg/kg).

Finally, divide the total dosage by the concentration of the available medication to find out how many milliliters to administer.

The available medication is 125 mg/mL,

so you would administer 20.07 mL (2509.2 mg / 125 mg/mL).

Rounded to the nearest tenth, the nurse should administer 20.1 mL.

Correct Answer is ["3.5"]

Explanation

To convert pounds to kilograms, divide by 2.2: 154 lb / 2.2 = 70 kg. Then multiply by the dosage per kilogram: 70 kg x 50 mcg/kg = 3500 mcg. Next, convert micrograms to milligrams by dividing by 1000: 3500 mcg / 1000 = 3.5 mg. Finally, use the formula D/H x Q to find the volume to administer, where D is the dose, H is the strength of the solution, and Q is the quantity of the solution. Plug in the values: 3.5 mg / 1 mg/mL x 1mL = 3.5 mL. Round to the nearest tenth: 3.5 mL. Therefore, the nurse should administer 3.5 mL of milrinone.
