A nurse is preparing a medication for a client and is converting grams to milligrams. Which of the following actions should the nurse take?
Move the decimal point 2 places to the right
Move the decimal point 3 places to the left.
Move the decimal point 3 places to the right
Move the decimal point 2 places to the left.
The Correct Answer is C
A. Move the decimal point 2 places to the right: To convert grams to milligrams, the decimal is moved 3 places to the right (1 gram = 1000 mg).
B. Move the decimal point 3 places to the left. This action would convert milligrams to grams, not the other way around.
C. Move the decimal point 3 places to the right.
When converting from grams (g) to milligrams (mg), the nurse must recognize that 1 gram = 1,000 milligrams. Grams to milligrams: To convert grams to milligrams, the nurse must multiply by 1,000, which involves moving the decimal point 3 places to the right.
D. Move the decimal point 2 places to the left. This would incorrectly convert from grams to a smaller unit.

Correct Answer is C
Explanation
A. "Stomach acid will inactivate some of the medication if I crush the medication." The purpose of the enteric coating is to protect the stomach lining from irritation, not to prevent inactivation by stomach acid.
B. "If I crush it you might experience a stomach ache or indigestion." While it’s true that crushing may cause stomach discomfort, the primary concern is that it would bypass the enteric coating.
C. "That would release all the medication at once, rather than over time." Crushing enteric-coated aspirin would cause the medication to be released all at once, potentially leading to side effects and reducing its intended effectiveness.
D. "I will crush it and mix it in some ice cream for you." Crushing enteric-coated medications is contraindicated, and it could cause harm.
Correct Answer is A
Explanation
A. Orange juice. Orange juice is high in vitamin C, which enhances the absorption of iron in the gastrointestinal tract.
B. Cheese: Dairy products, including cheese, can inhibit iron absorption due to the calcium content.
C. Milk: Similar to cheese, milk contains calcium, which can interfere with the absorption of iron.
D. Antacids containing magnesium: Antacids can decrease the absorption of iron, so they should not be taken together.
