A client is to receive LR 1000 ml over 8 hours. The IV tubing drop rate is 60 gtts/ml. What is the correct rate (gtts/min)? DOCUMENT ANSWER AS: RATE gtts/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 ["125"]

Calculate the total volume to be infused in drops.

Total drops = Total volume (mL) × Drop factor (gtts/mL)

= 1000 mL × 60 gtts/mL

= 60000 gtts

Calculate the total infusion time in minutes.

Total infusion time (minutes) = Total hours × 60 minutes/hour

= 8 hours × 60 minutes/hour

= 480 minutes

Calculate the IV flow rate in drops per minute (gtts/min).

IV rate (gtts/min) = Total drops / Total infusion time (minutes)

= 60000 gtts / 480 minutes

= 125

=125 gtts/min

Correct Answer is E

Explanation

A. contact the prescriber to decrease the rate of the D51/2NS during the blood transfusion: There's no need to alter the rate of maintenance fluids unless there's a fluid volume concern. Additionally, decreasing the rate would not address the need for a dedicated blood transfusion line if another lumen is available.

B. stop the D51/2NS, check the client's vitals & notify the prescriber: Stopping necessary fluids without cause may compromise fluid balance. Unless there's a compatibility issue or no other lumen, stopping the infusion is not the safest or most efficient action.

C. Fluids cannot be given through a CVC: Central venous catheters are routinely used for administering fluids, medications, and blood products, especially in critical care settings.

D. Insert a 22 gauge peripheral IV to administer the transfusion: While blood can be given through a peripheral IV, using an existing central venous catheter is safer and more efficient, especially when multiple lumens are available. Inserting a new IV unnecessarily increases infection and complication risks.

E. transfuse the unit of packed red blood cells through a separate lumen of the CVC: This is the safest and most appropriate action. Triple-lumen CVCs allow for simultaneous infusions through separate channels without mixing. Blood should be transfused through a dedicated lumen to avoid incompatibility or dilution by other fluids.

Correct Answer is ["2.5"]

Explanation

Convert the available dose from grams (Gm) to milligrams (mg):

0.15 Gm × 1000 mg/Gm = 150 mg

Desired dose = 75 mg

Available dose = 150 mg

Volume = 5 mL

Formula:

Volume to administer = Desired dose / Available dose × Volume

= 75 mg / 150 mg × 5 mL

= 0.5 × 5 mL

Volume to administer = 2.5 mL
