The healthcare provider prescribes magnesium sulfate 6 grams IV to be infused over 20 minutes for a 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"]
Step 1 is 6 grams ÷ (20 grams ÷ 500 mL) = 150 mL. Step 2 is (150 mL ÷ 20 min) × 60 min = 450 mL.
The final calculated answer is 450.

Correct Answer is D
Explanation
Choice A rationale
This choice suggests assessing if the child can administer the insulin. While it's important for children with diabetes to learn self-care skills, a 10-year-old may not yet be ready to take on the responsibility of injecting insulin regularly. The child might still rely on parental or caregiver support for this task. Moreover, it does not address the immediate issue of the mother's fear of needles.
Choice B rationale
This choice focuses on assessing the mother's parenting skills. It is not directly related to solving the issue of insulin administration. The mother's fear of needles does not necessarily reflect her overall parenting skills. Assessing parenting skills would not provide a practical solution to the child's need for insulin administration.
Choice C rationale
Encouraging the mother to handle the needles could help overcome her fear, but it might not be effective in the short term. The mother might need time and professional help to deal with her fear of needles. This choice does not provide an immediate solution for the child's need for insulin injections.
Choice D rationale
Asking if the father can help with the injections is a practical and immediate solution. If the father is available and comfortable with handling needles, he can take on the responsibility of administering insulin to the child. This ensures that the child's medical needs are met while giving the mother time to overcome her fear of needles.
Correct Answer is C
Explanation
Choice A rationale
Requesting extra staff to help with the nursing assessments may not be the most effective approach. It could increase the child's anxiety due to the presence of more unfamiliar people in the room. The primary goal is to create a calm environment that helps the child feel safe and more cooperative.
Choice B rationale
Explaining the reasons for the examination to the child may not be effective for a preschooler who may not fully understand or be comforted by such explanations. Young children often require more tangible and immediate means of reassurance and distraction.
Choice C rationale
Talking to the mother and gradually focusing on the child's toy is a practical approach. This strategy helps build rapport with both the mother and the child, and using the toy as a focal point can distract and comfort the child, making the examination process less intimidating and more cooperative.
Choice D rationale
Completing the assessment while allowing the child to cry may not be ideal. It can increase the child's distress and make the assessment more challenging. Addressing the child's emotional needs by providing comfort and distraction can lead to a more successful and less stressful examination.
