A nurse is preparing to administer Ringer's lactate 500 mL IV bolus to infuse over 3 hr. The drop factor of the manual IV tubing is 20 gtt/mL. The nurse should set the manual IV infusion 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.)
Answer and Explanation

The Correct Answer is ["56gtt\/min"]

To calculate the infusion rate in gtt/min, we need to know the total number of drops (gtt) needed

for the entire infusion and the time it takes to complete the infusion. Given:

  • Ringer's lactate: 500 mL
  • Infusion time: 3 hours
  • Drop factor: 20 gtt/mL

First, let's calculate the total number of drops needed for the entire infusion: Total drops = Volume (mL) × Drop factor (gtt/mL)

Total drops = 500 mL × 20 gtt/mL Total drops = 10,000 gtt

Next, we need to determine the infusion rate in gtt/min. Since the infusion time is given in hours, we need to convert it to minutes:

Infusion time (min) = Infusion time (hours) × 60 min/hour Infusion time (min) = 3 hours × 60 min/hour

Infusion time (min) = 180 min

Now, we can calculate the infusion rate in gtt/min:

Infusion rate (gtt/min) = Total drops / Infusion time (min) Infusion rate (gtt/min) = 10,000 gtt / 180 min

Infusion rate (gtt/min) ≈ 55.6 gtt/min (Rounded off- 56 gtt/min)

Correct Answer is ["2ml"]

Explanation

To calculate the amount of potassium chloride suspension the nurse should administer, we can use the formula:

Amount of medication (mL) = Desired dose (mEq) / Concentration (mEq/mL)

In this case, the desired dose is 20 mEq, and the concentration of the potassium chloride suspension is 10 mEq/mL.

Amount of medication (mL) = 20 mEq / 10 mEq/mL Amount of medication (Ml) = 2 mL

Therefore, the nurse should administer 2 mL of the potassium chloride suspension.
