A nurse is caring for a client who is in pre-term labor and receiving magnesium sulfate therapy.

The nurse should monitor the client for which of the following adverse effects of magnesium sulfate?

Hypertension

Hyperreflexia

Respiratory depression

Tachycardia

Answer and Explanation

The Correct Answer is C

Magnesium sulfate is a drug that is used to prevent seizures associated with pre-eclampsia and to stop preterm labor. However, it can also cause adverse effects such as respiratory depression, which is a condition where the breathing rate becomes too slow and shallow.

Respiratory depression can be life-threatening for both the mother and the baby, so the nurse should monitor the client’s respiratory rate and oxygen saturation closely.

Choice A is wrong because magnesium sulfate can cause hypotension, not hypertension. Hypotension is low blood pressure, which can lead to dizziness, fainting, and shock.

Choice B is wrong because magnesium sulfate can cause hyporeflexia, not hyperreflexia. Hyporeflexia is a reduced or absent reflex response, which can indicate magnesium toxicity.

The nurse should check the client’s deep tendon reflexes regularly and stop the infusion if they are absent.

Choice D is wrong because magnesium sulfate can cause bradycardia, not tachycardia.

Bradycardia is a slow heart rate, which can reduce the blood flow to vital organs.

Correct Answer is D

Explanation

“I will call my doctor if I have more than four contractions in an hour.” This statement indicates that the client understands the signs of preterm labor and when to seek medical attention.Preterm labor is defined as having regular contractions and cervical changes before 37 weeks of gestation.More than four contractions in an hour may indicate that preterm labor is occurring and requires prompt evaluation.

Choice A is wrong because drinking at least eight glasses of water every day is not a specific instruction for preventing preterm labor.However, dehydration can trigger contractions and should be avoided.

Choice B is wrong because lying on the back with a pillow under the knees can reduce blood flow to the uterus and the baby.This position can also increase the risk of blood clots in the legs.A better position is lying on the left side, which improves circulation and reduces pressure on the cervix.

Choice C is wrong because avoiding sexual intercourse until reaching term is not necessary for most women with a history of preterm labor.Sexual activity does not cause preterm labor or premature rupture of membranes (PROM).However, some women may be advised to abstain from sex if they have certain conditions, such as placenta previa or a short cervix.

A. The client reports decreased uterine contractions B. The client’s blood pressure decreases to within normal limits C. The client’s deep tendon reflexes are 2+ D. The client’s urine output increases to more than 30 mL/hr

Correct Answer is A

Explanation

Magnesium sulfate is a tocolytic drug that inhibits uterine activity and relaxes smooth muscles.The goal of magnesium sulfate therapy for a client who is in pre-term labor is to stop or reduce the frequency and intensity of contractions.

Choice B is wrong because the client’s blood pressure decreases to within normal limits.

Magnesium sulfate is not an antihypertensive drug and does not lower blood pressure.It is used to prevent seizures in clients with preeclampsia or eclampsia.

Choice C is wrong because the client’s deep tendon reflexes are 2+.

This is a normal finding and does not indicate the effectiveness of magnesium sulfate therapy.A decrease or loss of deep tendon reflexes may indicate magnesium toxicity, which is a serious complication that requires immediate intervention.

Choice D is wrong because the client’s urine output increases to more than 30 mL/hr.

This is also a normal finding and does not indicate the effectiveness of magnesium sulfate therapy.A decrease in urine output may indicate renal impairment or magnesium toxicity, which are both adverse effects of the drug.

The normal range for serum magnesium level is 1.5 to 2.5 mEq/L or 1.8 to 3 mg/dL.The therapeutic range for magnesium sulfate management is 5 to 8 mg/dL.
