A nurse needs to infuse three 1L bags over 12 hours. At what rate should the nurse program the pump to run in millilitres per hour?
(Round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["250"]

To calculate the infusion rate, you first need to determine the total volume to be infused and the total time over which the infusion will occur.

Three 1L bags need to be infused over 12 hours.

Total volume = 3 bags * 1000 mL/bag = 3000 mL

Total time = 12 hours

Now, to find the rate in milliliters per hour (mL/h), divide the total volume by the total time:

Infusion rate = Total volume / Total time

Infusion rate = 3000 mL / 12 hours = 250 mL/h

Correct Answer is C

Explanation

A. Avoiding the use of ice packs to treat muscle pain - While ice packs can cause skin damage in older adults with thinning skin, it is not the most appropriate response to the question. Protecting against shearing injuries is a more direct and specific concern related to thinning skin.

B. Protecting older adults against excessive sweat accumulation - Excessive sweat accumulation can lead to skin irritation, but this option does not directly address the issue of thinning skin as the primary concern in the question.

C. By protecting older adults against shearing injuries
Thinning skin in older adults makes them more vulnerable to skin injuries, especially shearing injuries. Shearing occurs when the skin is pulled in one direction while the underlying bone and tissues are pulled in the opposite direction. This can lead to skin tears and other wounds, which can be painful and slow to heal in older adults. Nurses should take special precautions to prevent shearing injuries, such as using lift sheets or sliding devices when moving patients, and ensuring that patients are repositioned frequently to reduce friction and shearing forces.

D. Avoiding the use of lotion on older adults' skin - Proper moisturization of the skin is important, especially in older adults, to prevent dryness and skin breakdown. Avoiding lotion is not a recommended practice; instead, choosing appropriate, non-irritating lotions can help maintain skin integrity.

Correct Answer is ["165"]

Explanation

To calculate the low range of the dosage, we need to use the lower end of the dosage range provided (1.5 mg/kg) and the client's weight in kilograms.

1 lb is approximately equal to 0.45 kg. So, to convert the client's weight from pounds to kilograms:

245 lbs * 0.45 kg/lb = 110.25 kg

Now, to calculate the low range dosage:

Low range dosage = 1.5 mg/kg * 110.25 kg = 165.375 mg

Rounding to the nearest whole number, the nurse should administer 165 mg for the low range of the dosage.
