A nurse is preparing to administer lactated Ringer's 75 mL/hr by continuous IV infusion. The drop factor on the manual IV tubing is 20 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 ["25"]
To calculate the IV flow rate in gtt/min, you need to multiply the infusion rate in mL/hr by the drop factor in gtt/mL and divide by 60 min/hr. In this case, the formula is (75 mL/hr x 20 gtt/mL) / 60 min/hr = 25 gtt/min. Therefore, the nurse should set the IV flow rate to deliver 25 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 ["30"]
Explanation
To solve this problem, the nurse needs to convert the client's weight from pounds to kilograms, and then use the formula:
mL/hr = (mcg/kg/min x kg x 60 min) / (mg/mL x 1000 mcg/mg)
The client's weight in kilograms is:
110 lb / 2.2 lb/kg = 50 kg
The concentration of dobutamine in mg/mL is:
250 mg / 250 mL = 1 mg/mL
Plugging these values into the formula, we get:
mL/hr = (10 mcg/kg/min x 50 kg x 60 min) / (1 mg/mL x 1000 mcg/mg) mL/hr = (30,000 mcg/min) / (1000 mcg/mg)
mL/hr = 30 mg/min
mL/hr = 30 mL/hr
Therefore, the nurse should set the IV pump to deliver 30 mL/hr.
