A client receives a prescription for 1 liter of lactated Ringer’s intravenously (IV) to be infused over 8 hours.

The IV administration set delivers 15 gtt/mL. How many mL/hr should the nurse program the infusion pump to deliver?

Answer and Explanation

The Correct Answer is ["125"]

Step 1 is to convert the volume of the prescription from liters to milliliters. 1 liter is equal to 1000 mL. So, the prescription is for 1000 mL of lactated Ringer’s.

Step 2 is to divide the total volume by the total time. The prescription is to be infused over 8 hours. So, 1000 mL ÷ 8 hours = 125 mL/hr. Therefore, the nurse should program the infusion pump to deliver 125 mL/hr.

Correct Answer is ["42"]

Explanation

Step 1: Convert the volume from liters to milliliters. 1 liter = 1000 mL. Step 2: Convert the time from hours to minutes. 4 hours = 240 minutes.

Step 3: Calculate the rate in mL per minute. Rate = Volume ÷ Time = 1000 mL ÷ 240 min = 4.17 mL/min.

Step 4: Calculate the drops per minute. Drops per minute = Rate × Drop factor = 4.17 mL/min

× 10 gtt/mL = 41.7 gtt/min.

Step 5: Round off the result to the nearest whole number. 41.7 gtt/min rounds off to 42 gtt/min.

A. Brown, rough, greasy, wart-like papules on the face. B. Thick skin plaques topped by silvery white scales. C. Requires sunglasses because sunlight hurts eyes. D. Tenderness upon palpation and generalized erythema.

Correct Answer is D

Explanation

Choice A rationale
Brown, rough, greasy, wart-like papules on the face are not typically associated with overexposure to PUVA treatment. These symptoms could be indicative of a different skin condition.
Choice B rationale
Thick skin plaques topped by silvery-white scales are characteristic of psoriasis vulgaris, not overexposure to PUVA treatment. PUVA is used to treat these symptoms, not cause them.
Choice C rationale
Needing sunglasses because sunlight hurts the eyes is not a typical sign of overexposure to PUVA treatment. This could be a sign of a different issue, such as an eye condition or side effect from a different medication.
Choice D rationale
Tenderness upon palpation and generalized erythema are signs of overexposure to PUVA treatment. If a patient is overexposed to PUVA, they may experience a burning sensation, discomfort, and redness at the treatment site.
