A pre-eclampsia patient is on magnesium sulfate. The nurse understands that magnesium sulfate will relax the smooth muscles, and should be alert for the development of:
1. Hypotension.
2. Hypertension.
3. Hypoglycemia.
4. Hyperglycemia.
1
Rationale:
1. The relaxation of smooth muscle will cause decreased vascular resistance in the blood vessels, resulting in hypotension.
2. Hypertension would be caused by increased vascular resistance.
3. Glycemic control is not dependent on smooth muscle.
4. Glycemic control is not dependent on smooth muscle.
