A nurse is to infuse two 1L bags of normal saline to a patient at 80ml/hr. How many hours will it take to infuse the total amount of normal saline?
(Round to the whole number. Assume no interruptions in the infusion.)
Answer and Explanation

The Correct Answer is ["25"]

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.

Correct Answer is B

Explanation

A. Use Echinacea to manage joint pain:
Echinacea is a natural supplement, but its effectiveness in managing joint pain related to osteoarthritis is not well-established. It's important for individuals to consult their healthcare provider before using any supplements, as they may interact with medications or have other adverse effects.

B. Maintain a recommended body weight.
Maintaining a healthy body weight is an important recommendation for managing osteoarthritis. Excess weight puts additional stress on weight-bearing joints, such as knees and hips, which can worsen osteoarthritis symptoms. Losing weight, if necessary, or maintaining a healthy weight can help reduce joint pain and improve mobility in individuals with osteoarthritis.

C. Apply ice to the joint before exercising:
Applying ice can help reduce inflammation and provide pain relief, but it's typically used after exercising or during acute flare-ups, not necessarily before exercising. Heat is often recommended before exercise to warm up the joint and improve flexibility.

D. Reduce the amount of purine in the diet:
This recommendation is more relevant for managing gout, a different type of arthritis caused by the buildup of uric acid crystals in the joints. Purine-rich foods can trigger gout attacks but are not directly related to osteoarthritis. Osteoarthritis is primarily related to wear and tear of the joints over time.

Correct Answer is ["200"]

Explanation

To calculate the rate at which the nurse should program the pump in milliliters per hour, you can use the following formula:

Rate (mL/hour) = Volume (mL) / Time (hours)

In this case, the volume is 1,000 mL (1 liter), and the time is 5 hours. Plugging these values into the formula:

Rate (mL/hour) = 1,000 mL / 5 hours = 200 mL/hour

So, the nurse should program the pump to administer the normal saline at a rate of 200 milliliters per hour.
