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.)

A. Stretching exercises:

Stretching exercises involve gently elongating muscles and tendons, promoting flexibility and range of motion. For individuals with osteoporosis, stretching exercises can improve balance and reduce the risk of falls, which is crucial as osteoporosis weakens bones and makes individuals more prone to fractures.
B. Riding a bicycle:

Bicycling is a low-impact cardiovascular exercise that is easy on the joints. It can help improve cardiovascular health, but it might not specifically address the balance and flexibility issues often associated with osteoporosis. However, it's a good option for overall fitness and joint health.
C. Walking briskly:

Brisk walking is an excellent low-impact aerobic exercise. It improves cardiovascular health, strengthens muscles, and aids in weight management. Walking can be adapted to various fitness levels, making it a suitable exercise for many older adults. While it doesn't specifically focus on flexibility, it promotes overall health and well-being.
D. High-impact aerobics:

High-impact aerobics involve activities like jumping, running, or intense dancing. These exercises can stress the bones and joints, potentially leading to injuries, especially for individuals with osteoporosis. High-impact exercises are generally discouraged for people with osteoporosis due to the increased risk of fractures.

To calculate the number of hours required to infuse two 1L bags of normal saline at a rate of 80 ml/hr, you can use the following formula:

Time (hours) = Total volume (ml) / Infusion rate (ml/hr)

First, calculate the total volume of normal saline to be infused:

Total volume = 2 bags x 1L/bag x 1000 ml/L = 2000 ml

Now, plug this into the formula:

Time (hours) = 2000 ml / 80 ml/hr

Time (hours) = 25 hours

So, it will take 25 hours to infuse the total amount of normal saline at a rate of 80 ml/hr, assuming no interruptions in the infusion. Rounded to the nearest whole number, it will take 25 hours.
