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 C
Explanation
Choice A rationale
Reduction of fever is not the primary goal of albumin therapy. Albumin's role in nephrotic syndrome is to manage severe edema, not to reduce fever, which might be managed by antipyretics if present.
Choice B rationale
Weight gain is typically undesirable in nephrotic syndrome patients due to fluid retention and edema. Albumin therapy aims to reduce edema, potentially decreasing weight as fluid balance improves.
Choice C rationale
Albumin infusion helps reduce edema by increasing plasma oncotic pressure, drawing fluid back into the vascular system. A reduction in edema indicates the therapy’s effectiveness in managing nephrotic syndrome symptoms.
Choice D rationale
Improved caloric intake is not directly affected by albumin infusion. While managing edema might improve overall well-being, albumin’s primary function in this context is fluid balance and reducing swelling.
