A nurse is preparing to administer dextrose 5% in water 350 mL IV to infuse over 3 hr. The drop factor of the manual IV tubing is 10 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 ["19"]

Drip rate (gtt/min) = (Volume to be infused in mL × Drop factor) ÷ Time of infusion in minutes

Given:

Volume to be infused = 350 mL Drop factor = 10 gtt/mL
Time of infusion = 3 hours = 180 minutes

Plugging these values into the formula:

Drip rate = (350 mL × 10 gtt/mL) ÷ 180 min Drip rate ≈ (3500 gtt) ÷ 180 min
Drip rate ≈ 19.4 gtt/min

Rounding to the nearest whole number, the drip rate is approximately 19 gtt/min. Therefore, the nurse should set the manual IV infusion to deliver 19 gtt/min.

Correct Answer is ["7.5"]

Explanation

Convert the client's weight from pounds to kilograms. We can use the formula 1 kg = 2.2 lb. So, 132 lb / 2.2 = 60 kg.

Calculate the total daily dose of chloramphenicol for the client. We can use the formula Dose (mg) = Weight (kg) x Dosage (mg/kg). So, 60 kg x 50 mg/kg = 3000 mg.

Divide the total daily dose by 4 to get the dose for each administration. So, 3000 mg / 4 = 750 mg.

Calculate the volume of chloramphenicol solution needed for each dose. We can use the formula Volume (mL) = Dose (mg) / Concentration (mg/mL). So, 750 mg / 100 mg/mL =

7.5 mL.

Round the answer to the nearest tenth. So, the nurse should give 7.5 mL of chloramphenicol solution with each dose.

A. Have another nurse verify the medication for the secondary infusion. B. Flush the IV site with sterile water prior to connecting the secondary infusion. C. Hang the secondary infusion higher than the primary IV infusion. D. Disconnect the primary IV infusion to connect the secondary infusion. E. None F. None

Correct Answer is C

Explanation

A.While medication verification is important, this is not specific to administering an intermittent IV bolus. It is standard practice for high-alert medications, not routine antibiotics.

B. Flushing the IV site with sterile water prior to connecting the secondary infusion is not standard practice. Normal saline is typically used to maintain patency, but it is not necessary before connecting the secondary infusion.
C.To administer a secondary infusion (e.g., antibiotic), the secondary bag must be hung higher than the primary infusion. This allows gravity to prioritize the secondary infusion through the Y-site.

D. Disconnecting the primary IV infusion to connect the secondary infusion is not correct. The secondary infusion should connect to the primary line without disrupting the ongoing infusion unless otherwise indicated.
