5 Weight-Based Dosage Calculations Online Quiz Questions

True or false: To convert a dose from milligrams to micrograms, multiply the number of milligrams by $1{,}000$.

A patient weighs $33\text{ lb}$. The order is $6\text{ mg/kg}$ per dose, with no stated dose limit. Using $2.2\text{ lb} = 1\text{ kg}$, what is the calculated dose?

True or false: A stated daily maximum can be treated as the maximum amount for each individual administration.

A patient weighs $24\text{ kg}$. The order is $7\text{ mg/kg}$ per dose, with a maximum of $180\text{ mg}$ per dose. The liquid contains $84\text{ mg}$ in $6\text{ mL}$. What volume is needed for one dose? Round to the nearest hundredth of a milliliter.

A patient weighs $25\text{ kg}$. The order is $9\text{ mg/kg}$ per dose, capped at $200\text{ mg}$ per dose. The liquid contains $100\text{ mg}$ in $5\text{ mL}$. What volume corresponds to the allowed dose?

A stated ceiling applies separately to every administration, rather than to the total amount given over 24 hours. What type of dose limit is this?

A patient weighs $22\text{ lb}$. The order is $30\text{ mg/kg/day}$, divided every 8 hours, with a maximum of $240\text{ mg/day}$. The liquid contains $120\text{ mg}$ in $5\text{ mL}$. Using $2.2\text{ lb} = 1\text{ kg}$, what volume is needed per administration? Round to the nearest hundredth of a milliliter.

A patient weighs $15\text{ kg}$. The order is $28\text{ mg/kg/day}$ divided every 6 hours, with a maximum of $360\text{ mg/day}$. The solution contains $240\text{ mg}$ in $8\text{ mL}$. Select all correct statements about the calculation.

A patient weighs $40\text{ kg}$. An infusion is ordered at $0.3\text{ mcg/kg/min}$, with a maximum of $15\text{ mcg/min}$. The prepared solution contains $1\text{ mg}$ in $100\text{ mL}$. Select all statements that correctly describe the dose, concentration, or pump rate.

A patient weighs $15\text{ kg}$. The order is $28\text{ mg/kg/day}$ divided every 6 hours, with a maximum of $360\text{ mg/day}$. The solution contains $240\text{ mg}$ in $8\text{ mL}$. Show the uncapped daily calculation, apply the limit, and determine the dose in milligrams and volume in milliliters for each administration.

Convert $0.08\text{ mg}$ to mcg. Enter the numerical value.

Using $2.2\text{ lb} = 1\text{ kg}$, what is the kilogram equivalent of $26.4\text{ lb}$?

True or false: A daily maximum applies to each individual administration, while a per-dose maximum applies to the total amount given over a day.

A solution contains $200\text{ mg}$ of medication in $8\text{ mL}$. What is its concentration?

A liquid contains $80\text{ mg}$ in $4\text{ mL}$. What volume provides a $240\text{ mg}$ dose? Enter the numerical value in mL.

A patient weighs $18\text{ kg}$ and is prescribed $12\text{ mg/kg}$ per dose, with a maximum of $300\text{ mg}$ per dose. What dose is calculated before converting to volume?

A patient weighs $44\text{ lb}$. The order is $8\text{ mg/kg}$ per dose, capped at $150\text{ mg}$ per dose. The vial contains $100\text{ mg/mL}$. Using $2.2\text{ lb} = 1\text{ kg}$, what volume corresponds to the allowed dose?

A $12\text{ kg}$ patient is prescribed $30\text{ mg/kg/day}$ divided every $8\text{ hours}$, with a maximum of $300\text{ mg/day}$. The liquid contains $180\text{ mg}$ per $5\text{ mL}$. What volume should be given per administration? Round to the nearest hundredth of a milliliter.
