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 ["14"]
Explanation
To answer this question, the nurse needs to perform the following steps:
Convert the client's weight from pounds to kilograms by dividing it by 2.2. 154 lb / 2.2 = 70 kg.
Multiply the client's weight by the loading dose of phenytoin to get the total dose in milligrams. 70 kg x 10 mg/kg = 700 mg.
Divide the total dose by the concentration of phenytoin to get the volume in milliliters. 700 mg / 50 mg/mL = 14 mL.
Round the volume to the nearest whole number. The nurse should administer 14 mL of phenytoin by IV bolus.
Correct Answer is ["60"]
Explanation
To calculate the infusion rate of lidocaine, we need to convert the dose from mg/min to mg/hr and then to mL/hr.
The prescribed dose is 4 mg/min, so the hourly dose is 4 x 60 = 240 mg/hr.
The concentration of the drug is 1 g in 250 mL, which is equivalent to 1000 mg in 250 mL or 4 mg in 1 mL.
Therefore, the volume per hour is 240 / 4 = 60 mL/hr.
Rounded to the nearest whole number, the nurse should set the IV pump to deliver 60 mL/hr.
