A patient is being administered magnesium sulfate for preterm labor. The patient's serum magnesium level is elevated at 11 mg/dL. With what sign or symptom will the patient likely present?
A) Tachypnea
B) Muscle rigidity
C) Tachycardia
D) Depressed deep tendon reflexes
D
Feedback:
Hypermagnesemia will cause depressed deep tendon reflexes. The serum magnesium level of 11 mg/dL would result in depressed respirations. The serum magnesium level of 11 would result in decreased muscle strength. The serum level of 11 mg/dL would result in bradycardia, not tachycardia.
