The nurse is providing care to a postpartum patient after an emergency cesarean due to eclampsia. The patient received spinal anesthesia before delivery. Magnesium sulfate is infusing 2 g/hr in 100 mL of IV fluid.
Which assessment finding will cause the nurse to administer calcium gluconate to the patient via IV push?

A.

Respiratory rate is 18 breaths/min.

B.

Urinary output remains at 30 mL/hr.

C.

Patella reflexes are rated at one.

D.

Serum magnesium level is 10 mg/dL. . .

Answer and Explanation

The Correct Answer is D

Choice A rationale

A respiratory rate of 18 breaths/min is normal and does not indicate magnesium toxicity or the need for calcium gluconate.

 

Choice B rationale

Urinary output of 30 mL/hr is within the acceptable range and does not suggest magnesium toxicity. This indicates adequate renal function.

 

Choice C rationale

Patellar reflexes rated at one indicate mild hyporeflexia, which can be a side effect of magnesium sulfate but does not necessitate immediate intervention.

 

Choice D rationale

Serum magnesium level of 10 mg/dL is significantly elevated, indicating magnesium toxicity. Calcium gluconate is the antidote for magnesium toxicity and should be administered

promptly to prevent severe complications.

Correct Answer is B

Explanation

Choice A rationale

Swaddling provides warmth but doesn't address jitteriness, which may be due to hypoglycemia.

Choice B rationale

Jitteriness in a newborn can indicate hypoglycemia. Prompt glucose assessment is crucial for early detection and management.

Choice C rationale

Feeding could help with glucose levels, but without knowing the glucose status, it might not be the immediate priority.

Choice D rationale

Routine medications are important but not as urgent as addressing possible hypoglycemia in a jittery baby.

Correct Answer is B

Explanation

Choice A rationale

While massaging the fundus and ensuring IV access are correct initial actions, methylergonovine (Methergine) is typically used for patients without hypertensive history due to its

potential to raise blood pressure.

Choice B rationale

This option correctly identifies initial steps and appropriate medication. Carboprost-tromethamine (Hemabate) is effective in controlling postpartum hemorrhage and can be safely

used in patients with hypertension when oxytocin is insufficient.

Choice C rationale

Quantifying blood loss is essential but it is not an immediate priority when the patient is showing signs of significant bleeding and instability. Immediate intervention to control bleeding

takes precedence.

Choice D rationale

Assisting the patient to the restroom and then massaging the fundus overlooks the immediate need to control bleeding. This approach may delay necessary treatment and increase

the risk of further hemorrhage.

Choice E rationale

Straight catheterization and oxytocin maintenance are part of the management of postpartum hemorrhage but do not address the immediate need to ensure uterine contraction and

control active bleeding as effectively as the initial steps outlined in Choice B. .
