. nurse is assisting with the care of a client with PROM and is receiving magnesium sulfate IV at 2 g/hr. Which of the following findings indicates that it is safe for the nurse to continue the infusion?

Heart rate of 55/min

Urine output of 50 mL in 4 hr

Diminished deep-tendon reflexes

Respiratory rate of 16/min

Answer and Explanation

The Correct Answer is D

A. Heart rate of 55/min. A heart rate of 55/min is bradycardia, which may indicate magnesium toxicity. This is a concerning sign and does not indicate safety to continue.

B. Urine output of 50 mL in 4 hr. A urine output of only 50 mL in 4 hours is too low (less than 30 mL/hr is concerning) and may indicate toxicity, since magnesium sulfate is excreted via the kidneys.

C. Diminished deep-tendon reflexes. Diminished deep-tendon reflexes (DTRs) may indicate magnesium toxicity. DTRs are monitored to assess for toxicity.

D. Respiratory rate of 16/min. A normal respiratory rate (12-20 breaths per minute) indicates that the magnesium sulfate has not caused respiratory depression, a sign of magnesium toxicity.

Correct Answer is A

Explanation

A. Weakened uterine contractions: Terbutaline is a tocolytic medication used to relax the uterus and reduce or stop preterm uterine contractions.

B. Maternal glucose 63 mg/dL: Terbutaline can cause hyperglycemia, not hypoglycemia. Therefore, a glucose level of 63 mg/dL would not be an expected finding.

C. Enhanced fetal lung surfactant: Betamethasone, not terbutaline, is used to enhance fetal lung maturity by increasing surfactant production.

D. Fetal heart rate 100/min:Terbutaline can cause tachycardia, so a fetal heart rate of 100/min (bradycardia) would be unexpected.

Correct Answer is ["6"]

Explanation

Using the formula:

Dose= (Prescribedamount ÷ Availablestrength) × Volume

= (300 mg ÷ 250 mg) × 5 mL

= 6mL

The nurse should administer 6 mL of the solution.
