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.)
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 D
Explanation
A. "I will reduce my intake of sodium." - This statement is correct. High sodium intake can lead to increased calcium excretion through the urine, which can weaken bones. Reducing sodium intake can help prevent osteoporosis.
B. "I will limit my intake of soft drinks." - This statement is correct. Soft drinks, especially cola beverages, contain phosphoric acid, which can leach calcium from bones, leading to decreased bone density. Limiting soft drink consumption is advisable for bone health.
C. "I will decrease my intake of caffeine." - This statement is correct. Excessive caffeine consumption can interfere with calcium absorption and increase calcium excretion. It is advisable to limit caffeine intake to prevent osteoporosis.
D. "I will reduce my intake of vitamin K-rich foods." - This statement is incorrect. Vitamin K is essential for bone health as it helps in bone mineralization and reduces the risk of fractures. Foods rich in vitamin K, such as leafy green vegetables, are beneficial for bone health and should not be reduced unless there are specific medical reasons to do so.
Correct Answer is D
Explanation
A. Void every 6 to 8 hours:This interval may not be frequent enough. It is generally recommended to void every 2 to 3 hours to help flush out bacteria and reduce the risk of infection.
B. Avoid voiding immediately after sexual intercourse.This is not recommended. It is actually advised to void immediately after sexual intercourse to help flush out any bacteria that may have entered the urethra.
C. Take a bubble bath daily and keep the perineal region clean:
While keeping the perineal region clean is important for general hygiene, taking bubble baths and using heavily scented products can irritate the urethra and potentially increase the risk of UTIs. The nurse should advise against frequent bubble baths and suggest using mild, unscented soaps for the perineal area.
D. Increase the daily amount of water consumed:
Drinking more water helps increase urine output, which helps flush out bacteria from the urinary tract and can reduce the risk of recurrent UTIs.
