A client with heart failure (HF) is receiving an IV infusion of 0.9% normal saline 250 mL at a keep-vein-open (KVO) rate of 40 mL/hour. The IV tubing has a mini drip chamber that delivers 60 micro drops/mL. The nurse should regulate the micro drop gravity IV infusion to deliver how many micro drops/minute?
(Enter numeric value only.)
The Correct Answer is ["40"]
A client with heart failure (HF) is receiving an IV infusion of 0.9% normal saline 250 mL at a keep-vein-open (KVO) rate of 40 mL/hour.
The IV tubing has a minidrip chamber that delivers 60 microdrops/mL.
To calculate the infusion rate in microdrops/minute, we need to multiply the infusion rate in mL/hour (40 mL/hour) by the number of microdrops/mL (60 microdrops/mL) and divide by the number of minutes in an hour (60 minutes/hour).
The nurse should regulate the microdrop gravity IV infusion to deliver 40 microdrops/minute (40 mL/hour * 60 microdrops/mL / 60 minutes/hour).

Correct Answer is ["0.75"]
Explanation
The healthcare provider prescribes interferon beta-1b 0.1875 mg every other day for a client with multiple sclerosis.
The nurse reconstitutes the single-use vial of powder labeled 0.3 mg with 1.2 mL of sterile water, so the concentration of interferon beta-1b in the solution is 0.25 mg/mL (0.3 mg / 1.2 mL).
Since the healthcare provider prescribes 0.1875 mg of interferon beta-1b, the nurse should administer 0.75 mL of medication (0.1875 mg / 0.25 mg/mL).
Correct Answer is ["2"]
Explanation
The bottle is labeled "Ibuprofen for Oral Suspension, USP 100 mg per 5 mL." This means that for every 5 mL (or 1 teaspoon) of the suspension, there is 100 mg of ibuprofen.
To administer a dose of 200 mg, the parent should give the child 2 teaspoons (10 mL) of the suspension.
