Rounding Rule for Drops (gtt)

Round to the nearest whole drop.

Rounding Rule for Milligrams (mg)

Round to the nearest whole mg.

Rounding Rule for Milliliters (mL) Under 1 mL

If the final answer is under $1\,\text{mL}$, round to the nearest hundredth (for example, $0.98$).

Rounding Rule for Milliliters (mL) Over 1 mL

If the final answer is over $1\,\text{mL}$, round to the nearest tenth (for example, $1.9$).

Rounding Rule for Kilograms (kg)

When strictly asked for $\text{kg}$, round to the nearest hundredth (for example, $75.12\,\text{kg}$).

Leading Decimal Rule in Medical Math

Always include a zero before the decimal point (for example, $0.9$ is correct, not $.9$).

Trailing Zero Rule in Medical Math

Do not include trailing zeros after a decimal point (for example, $0.9$ is correct, but not $0.90$).

Rounding Rule for Infusion Questions in mL

Round to whole $\text{mL}$ unless directions specify otherwise.
