The healthcare provider prescribes magnesium sulfate 6 grams intravenously (IV) to be infused over 20 minutes for client with preterm labor. The IV bag contains magnesium sulfate 20 grams in dextrose 5% in water 500 mL. How many mL/hour should the nurse set the infusion pump?
(Enter numerical value only.)
The Correct Answer is ["450"]
- To calculate the infusion rate, use the formula:
(mL of solution / grams of drug) x (grams ordered / minutes to infuse) x 60
- In this case, the formula becomes: (500 mL / 20 g) x (6 g / 20 min) x 60
- Simplify and solve: (25 mL / g) x (0.3 g / min) x 60
- The answer is 450 mL/hour
- The nurse should set the infusion pump at 450 mL/hour

Correct Answer is B
Explanation
A. Request a return demonstration of a diaper change:While it's useful for parents to know how to change a diaper, feeding is more critical for the infant’s health and development in the early days.
B. Evaluate infant feeding techniques prior to discharge:Ensuring that the parents understand how to properly feed their newborn is crucial. Proper feeding techniques are essential for the infant's nutrition, growth, and development. Issues with feeding can lead to dehydration, weight loss, and other health problems. Therefore, this is the most important intervention.

B. Postprandial blood glucose test: This test measures blood sugar levels after meals. While it can provide information about how the body processes glucose after eating, it's not the primary test for diagnosing gestational diabetes.
C. Fasting blood glucose: This test measures blood sugar levels after a period of fasting. It is a standard test used to diagnose gestational diabetes.
