Your patient is receiving Heparin via a continuous IV infusion at a rate of 1600 units per hour.
The bag is labeled N/S 500 mLs and contains Heparin 40,000 units.
What rate should the IV pump be set at to deliver this ordered amount of Heparin? mLs/hr.
The Correct Answer is ["mLs\/hr."]
Answer and explanation
Step 1 is to calculate the total units of Heparin in 1 mL of the solution. This is done by dividing the total units of Heparin in the bag (40,000 units) by the total volume of the bag (500 mL). So, 40,000 units ÷ 500 mL = 80 units/mL. Step 2 is to calculate the rate at which the IV pump should be set. This is done by dividing the ordered amount of Heparin per hour (1600 units) by the units of Heparin per mL (80 units/mL). So, 1600 units/hr ÷ 80 units/mL = 20 mL/hr.
So, the correct answer is 20 mL/hr.

Correct Answer is A
Explanation
Choice A rationale:
Estrogen deficiency is the primary cause of hot flashes and night sweats in postmenopausal women. As estrogen levels decrease, it affects the hypothalamus, which is responsible for regulating body temperature, leading to these symptoms.
Choice B rationale:
Changes in vaginal pH occur during menopause due to estrogen deficiency, but this is not the primary cause of hot flashes and night sweats.
Choice C rationale:
An active lifestyle can help manage symptoms of menopause, but it is not the primary cause of hot flashes and night sweats.
Choice D rationale:
Poor dietary intake can exacerbate symptoms of menopause, but it is not the primary cause of hot flashes and night sweats.
