A nurse is caring for a client who is receiving intravenous magnesium sulfate for preeclampsia.
Which assessment finding would alert the nurse to suspect magnesium toxicity?

A.

Rapid pulse.

B.

Tingling in toes.

C.

Cool skin temperature.

D.

Absent deep tendon reflexes.

Answer and Explanation

The Correct Answer is D

Choice A rationale

A rapid pulse is not typically associated with magnesium toxicity. Magnesium toxicity more commonly affects the nervous and muscular systems.

 

Choice B rationale

Tingling in toes can be a sign of early magnesium sulfate effects but not necessarily toxicity. It may indicate that the medication is starting to affect the nervous system.

 

Choice C rationale

Cool skin temperature is not a common sign of magnesium toxicity. Symptoms of magnesium toxicity are more related to neuromuscular and respiratory function.

 

Choice D rationale

Absent deep tendon reflexes are a key indicator of magnesium toxicity. This finding suggests that magnesium levels are high enough to depress neuromuscular function, requiring immediate medical intervention. .

Correct Answer is ["A","B","C"]

Explanation

Choice A: Give betamethasone 12 mg IM now and repeat in 24 hr.

Rationale: Betamethasone is administered to accelerate fetal lung maturity in cases of preterm labor. Given the client's gestational age of 31 weeks, this intervention is appropriate to help reduce the risk of respiratory distress syndrome in the newborn.

Choice B: Begin loading dose of magnesium sulfate 9 g over 30 min.

Rationale: Magnesium sulfate is used for neuroprotection of the fetus in preterm labor to reduce the risk of cerebral palsy. The loading dose is typically given to achieve therapeutic levels quickly.

Choice C: Position the client in a lateral position.

Rationale: Positioning the client in a lateral position helps improve uteroplacental blood flow and can reduce the intensity of contractions, which is beneficial in managing preterm labor.

Correct Answer is B

Explanation

Choice A rationale

Accidental lacerations are possible during a cesarean delivery, but they are typically managed quickly and are not the most critical issue immediately after birth.

Choice B rationale

Respiratory distress is the priority assessment for a newborn following a cesarean delivery because cesarean births can increase the risk of transient tachypnea or other respiratory complications due to the lack of labor-induced respiratory adaptation.

Choice C rationale

Hypothermia is a concern for all newborns, but respiratory distress takes precedence in the immediate post-delivery period, especially following cesarean delivery.

Choice D rationale

Acrocyanosis is a common and typically benign condition in newborns, not requiring immediate intervention compared to respiratory distress.
