A nurse needs to convert 2.5 grams to milligrams. How should the nurse move the decimal point?
Move the decimal point three places to the right
Move the decimal point two places to the right
Move the decimal point three places to the left
Move the decimal point two places to the left
The Correct Answer is A
A. Move the decimal point three places to the right: Converting grams to milligrams requires multiplying by 1,000 because 1 gram = 1,000 milligrams. Moving the decimal three places to the right converts 2.5 g to 2,500 mg accurately.
B. Move the decimal point two places to the right: Moving the decimal only two places would convert 2.5 g to 250 mg, which is ten times less than the correct amount, leading to underdosing.
C. Move the decimal point three places to the left: Moving the decimal left would convert 2.5 g to 0.0025 mg, which is drastically smaller than the intended dose, risking ineffective treatment.
D. Move the decimal point two places to the left: This would convert 2.5 g to 0.025 mg, which is far below the correct dose and would result in severe underdosing.

Correct Answer is A
Explanation
Calculation:
Desired Dose (D): 50 mg
Available Dose (H): 100 mg
Quantity (Q): 1 tablet
- Apply the desired over have formula
Tablets to administer = (Desired Dose ÷ Available Dose) × Quantity
Tablets to administer = (50 ÷ 100) × 1
Tablets to administer = 0.5 tablets
Correct Answer is B
Explanation
A. Administer the medication immediately upon receiving it: Immediate administration without verification increases the risk of errors, particularly with high-alert medications that require precise dosing and careful checks.
B. Double-check all rights of medication administration independently with another nurse: High-alert medications carry a higher risk of causing significant harm if administered incorrectly. Independent double-checks of all rights—including drug, dose, route, time, and patient—ensure safe administration and reduce the likelihood of errors.
C. Rely on the automated dispensing system for accuracy: While automated systems aid safety, they are not foolproof. Human verification is essential, especially for high-alert medications, to prevent misfills, incorrect dosing, or patient-specific errors.
D. Skip the bedside verification to save time: Omitting bedside verification eliminates a critical safety step and increases the risk of administering the wrong drug or dose, which can result in serious patient harm.
