Which is a common adverse effect of magnesium-based antacid preparations?

A.

Constipation

B.

Diarrhea

C.

Heartburn

D.

Rebound indigestion

Answer and Explanation

The Correct Answer is B

A. Constipation: This is a common side effect of calcium-based or aluminum-based antacids, not magnesium-based.

B. Diarrhea: Magnesium-based antacid preparations, such as magnesium hydroxide, commonly cause diarrhea because magnesium has an osmotic effect in the intestines, drawing water into the bowel and increasing motility.

C. Heartburn: Magnesium-based antacids are used to treat heartburn, not cause it.

D. Rebound indigestion: This is more commonly associated with calcium-based antacids, such as calcium carbonate.

A. "No. The color will fade gradually as liver inflammation decreases.": This response provides accurate information and reassurance, addressing the patient's concerns about her appearance while being supportive.

B. "Yes, but cosmetics can disguise the color.": This dismisses the patient’s concerns and is not empathetic or accurate, as jaundice usually resolves when liver function improves.

C. "Yes, but your sclera will return to their previous white color.": While the sclera may clear up, this does not address the entire issue of jaundice affecting skin color.

B. Urinary infections: Liver disease does not directly increase the risk of urinary infections.
