A nurse is preparing to administer lactated Ringer's 100 mL/hr by continuous IV infusion. The drop factor of the manual IV tubing is 15 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. De not use a trailing zero.)
The Correct Answer is ["25"]
To calculate the IV flow rate in gtt/min, use the formula: (mL/hr x drop factor) / 60 min. Plug in the values: (100 mL/hr x 15 gtt/mL) / 60 min = 25 gtt/min. Round to the nearest whole number: 25 gtt/min.

Correct Answer is ["286"]
Explanation
To solve this problem, the nurse needs to convert the client's weight from pounds to kilograms, and then use the formula:
mL = (mg/kg x kg) / (mg/mL)
The client's weight in kilograms is:
126 lb / 2.2 lb/kg = 57.27 kg
The concentration of foscarnet in mg/mL is:
6,000 mg / 500 mL = 12 mg/mL
Plugging these values into the formula, we get:
mL = (60 mg/kg x 57.27 kg) / (12 mg/mL)
mL = (3,436.2 mg) / (12 mg/mL)
mL = 286.35 mL
Therefore, the nurse should administer 286 mL of foscarnet.
Correct Answer is ["38"]
Explanation
To solve this problem, the nurse needs to find the concentration of lidocaine in the solution, which is 1 g / 250 mL = 0.004 g/mL.
Then, the nurse needs to convert the dosage of lidocaine from mg/min to g/hr, which is 2.5 mg/min x 60 min/hr x 0.001 g/mg = 0.15 g/hr. Finally, the nurse needs to divide the dosage by the concentration to get the infusion rate, which is 0.15 g/hr / 0.004 g/mL = 37.5 mL/hr.
Rounding to the nearest whole number, the nurse should set the IV pump to deliver 38 mL/hr.
