A nurse is preparing to administer dextrose 5% in water (DSW) 1,200 ml. IV to infuse over 24 hr. The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round 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 ["13"]

To calculate the infusion rate in drops per minute (gtt/min), we can use the following formula: Infusion rate (gtt/min) = (Volume to be infused (ml) * Drop factor) / Time (min) Given:

Volume to be infused: 1,200 ml

Drop factor: 15 gtt/ml

Time: 24 hr

First, we need to convert the time from hours to minutes:

24 hr * 60 min/hr = 1,440 min

Now, we can calculate the infusion rate:

Infusion rate (gtt/min) = (1,200 ml * 15 gtt/ml) / 1,440 min

Simplifying the equation:

Infusion rate (gtt/min) = 18,000 gtt / 1,440 min

Dividing both sides:

Infusion rate (gtt/min) ≈ 12.5 gtt/min

Rounding the answer to the nearest whole number, the nurse should set the manual IV infusion to deliver approximately 13 gtt/min.

Correct Answer is B

Explanation

Furosemide is a loop diuretic commonly prescribed for conditions such as hypertension and edema. One of the side effects of furosemide is the increased excretion of potassium in the urine, which can lead to low potassium levels in the body, known as hypokalemia. The other medications mentioned do not typically place the client at risk for hypokalemia: Acyclovir 400 mg PO twice daily: Acyclovir is an antiviral medication used to treat viral infections, such as herpes. It does not have a direct effect on potassium levels. Cimetidine 300 mg PO four times per day: Cimetidine is a histamine H2 receptor antagonist commonly used to reduce stomach acid production. It does not have a direct effect on potassium levels.

Meloxicam 5 mg PO once daily: Meloxicam is a nonsteroidal anti-inflammatory drug (NSAID) used for pain relief. It does not have a direct effect on potassium levels.

Correct Answer is ["100"]

Explanation

To calculate the IV flow rate in drops per minute (gtt/min), you can use the following formula: Flow rate (gtt/min) = (Volume to be infused in mL) x (Drop factor) / (Time in minutes) In this case, the volume to be infused is 100 mL, the drop factor is 60 gtt/mL, and the time is 60 minutes.

Flow rate (gtt/min) = (100 mL) x (60 gtt/mL) / (60 min)

Canceling out the mL and min units, the formula becomes:

Flow rate (gtt/min) = 100 x 60 / 60

Flow rate (gtt/min) = 100

Therefore, the nurse should set the IV flow rate to deliver 100 gtt/min.
