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 ["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.
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.
