A nurse is caring for a client who has severe pre-eclampsia and is receiving hydralazine IV.
Which of the following adverse effects should the nurse monitor for?
Tachycardia
Hyperglycemia
Hypokalemia
Constipation
The Correct Answer is A
Hydralazine can cause tachycardia (fast heart rate) as a common side effect.
This is because hydralazine lowers blood pressure by relaxing blood vessels, which can make the heart beat faster to compensate.
Choice B is wrong because hydralazine does not cause hyperglycemia (high blood sugar).
Hydralazine is not known to affect glucose metabolism or insulin secretion.
Choice C is wrong because hydralazine does not cause hypokalemia (low potassium levels).
Hydralazine is not a diuretic and does not increase potassium excretion.
Choice D is wrong because hydralazine does not cause constipation. Hydralazine can cause diarrhea as a common side effect, but not constipation.
