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 ["30"]
Explanation
To administer potassium gluconate 40 mEq PO, the nurse should use the following formula: mL = (mEq / mEq/mL) x mL. Plugging in the values from the question, we get: mL = (40 / 20) x 15. Simplifying, we get: mL = 30.
Therefore, the nurse should administer 30 mL of potassium gluconate liquid.
Correct Answer is ["0.25"]
Explanation
To convert micrograms to milligrams, divide by 1000: 250 mcg / 1000 = 0.25 mg. Round to the nearest hundredth: 0.25 mg. Therefore, the nurse should administer 0.25 mg of filgrastim.
