A nurse is preparing to administer Ringer lactate 500 mL intravenous (IV) bolus to infuse over 3 hours. The drop factor of the manual IV tubing is 2 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 ["56"]

To calculate the infusion rate, we'll use the following formula:

Infusion rate (gtt/min) = (Volume to be infused (mL) / Time (min)) Drop factor (gtt/mL)

First, calculate the total time in minutes:

3 hours 60 minutes/hour = 180 minutes

Then, calculate the volume per minute:

500 mL / 180 minutes = 2.78 mL/min

Finally, multiply the volume per minute by the drop factor:

2.78 mL/min 20 gtt/mL = 55.6 gtt/min

Therefore, the nurse should set the manual IV infusion to deliver 56 gtt/min.

Correct Answer is D

Explanation

A. A client who has a fractured fibula and tibia: This is incorrect. While serious, this injury does not require immediate life-saving intervention and is generally categorized as less urgent.
B. A client who has sustained a major burn to their upper torso and extremities: This is incorrect. Although severe, if the client is stable and responsive, they may be categorized as yellow (delayed) unless there are immediate life-threatening complications.
C. A client who has a sprained ankle and laceration to the lower leg: This is incorrect. These injuries are considered less severe and would typically be tagged as green (minor).
D. A client who has an open traumatic brain injury and agonal breaths: This is correct. Agonal breaths and severe head injury indicate a need for immediate life-saving intervention, so this client should receive a red tag for the highest priority.

Correct Answer is ["675"]

Explanation

To calculate the appropriate dose of vancomycin, follow these steps:

Convert pounds to kilograms:
- 198 lb (1 kg / 2.2 lb) = 90 kg
Calculate the total daily dose:
- 15 mg/kg/day 90 kg = 1350 mg/day
Determine the dose per administration:
- 1350 mg/day / 2 doses/day = 675 mg/dose
