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 C
Explanation
A. Schedule an appointment for the client with the diabetic nurse educator:
This could be a helpful action. The diabetic nurse educator can provide valuable support and education on managing insulin needs during breastfeeding.
B. Counsel her to increase her caloric intake:
While adequate nutrition is essential, increasing caloric intake may not be the primary factor affecting insulin needs. It's important to consider the specific needs of the client, and any adjustments to insulin should be made based on careful monitoring.
C. Inform her that a decreased need for insulin occurs while breastfeeding:
This is accurate information. Breastfeeding can lead to a decreased need for insulin in some individuals. The nurse should provide education on this aspect of managing diabetes during breastfeeding.
D. Advise the client to breastfeed more frequently:
While breastfeeding frequency can impact insulin needs, it's essential to consider the overall picture. Simply increasing breastfeeding frequency may not be the only factor affecting insulin requirements.
Correct Answer is D
Explanation
A. Discuss options for intrauterine surgical correction of congenital defects:At this point, the AFP result is only an indicator, not a diagnosis. The client has not undergone sufficient diagnostic evaluation (such as ultrasound) to confirm any congenital defect that would warrant intrauterine surgery. Treatment options can only be discussed once a definitive diagnosis has been made.
B. Inform her that a repeat alpha-fetoprotein (AFP) should be evaluated:While a repeat AFP test could be done in some cases to rule out lab error or confirm the result, this is not typically the immediate next step. An ultrasound provides more definitive and comprehensive information than simply repeating the AFP test.
C. Reassure the client that the AFP results are likely to be a false reading:Providing false reassurance may lead to misunderstandings. While false positives can happen, it's crucial to follow up with further assessments to ensure the accuracy of the results.
D. Explain that a sonogram should be scheduled for definitive results:An elevated AFP level is a screening test, not a definitive diagnosis. A sonogram (ultrasound) is the next step to obtain more detailed information about the fetus. Ultrasound can help assess for neural tube defects, confirm gestational age, and check for other anomalies that could explain the elevated AFP levels. This provides the most accurate and non-invasive method for evaluating potential fetal abnormalities.
