Which is a common adverse effect of magnesium-based antacid preparations?
Constipation
Diarrhea
Heartburn
Rebound indigestion
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.

Explanation
A. 1.25ml: The dosage of 20mg/5ml means 1ml contains 4mg. To get 25mg, you need more than 1.25ml.
B. 6.25ml: Since 20 mg is in 5ml, to administer 25mg, you can use the following calculation:
25mg*
= 6.25ml
C. 6.3mg: This is incorrect because the dosage needed is 25mg, not 6.3mg.
D. 6mg: The prescribed dose is 25mg, not 6mg.
Correct Answer is B
Explanation
A. Fats: Restricting fats is not typically indicated in cirrhosis, unless the patient has specific issues like gallbladder disease or pancreatitis.
B. Protein: When ammonia levels rise in cirrhosis (leading to hepatic encephalopathy), restricting protein intake can help reduce the production of ammonia, as proteins are broken down into ammonia in the body.
C. Carbohydrates: Carbohydrates are generally not restricted in cirrhosis. They are important for energy, especially in patients with liver disease.
D. Water-soluble vitamins: There is no need to restrict water-soluble vitamins in cirrhosis unless there is a specific deficiency or malabsorption.
