Medication Dosage Calculations - NCLEX-PN

$17,\text{gtt/min}$. Applies the drip rate formula and rounds to the nearest whole number for manual regulation.

$70,\text{kg}$. Converts pounds to kilograms by dividing by 2.2, yielding an exact result in this case.

$200,\text{mg}$. Multiplies the dosage rate per kilogram by the patient's weight to calculate the total dose.

$1,\text{mL}$. Proportions the volume by dividing the desired dose by the concentration and multiplying by the vial's volume per dose.

$200,\text{mcg}$. Converts milligrams to micrograms by multiplying by 1000 according to metric prefixes.

$\text{mL/hr} = \frac{\text{mL}}{\text{hr}}$. Provides the hourly infusion rate by dividing the total volume by the total number of hours for infusion.

$\text{gtt/min} = \frac{\text{mL} \times \text{gtt/mL}}{\text{min}}$. Determines the drip rate by multiplying the volume in milliliters by the drop factor and dividing by the time in minutes.

$\text{Give} = \frac{D}{H} \times Q$. Calculates the amount to administer by dividing the desired dose by the available dose and multiplying by the quantity per unit.

$30,\text{gtt/min}$. Multiplies volume by drop factor and divides by total minutes to find the drip rate.

$125,\text{mL/hr}$. Divides the total volume by the infusion duration to obtain the hourly rate.

$4,\text{mL}$. Converts the ordered dose to matching units and proportions the volume based on concentration.

$3,\text{tablets}$. Determines the quantity by dividing the ordered dose by the strength per tablet.

$10,\text{mL}$. Scales the volume proportionally using the ratio of ordered dose to available concentration.

$\text{kg} = \frac{\text{lb}}{2.2}$. Converts pounds to kilograms by dividing by the standard factor of 2.2 for weight-based calculations.

$\text{Dose} = (\text{mg/kg}) \times (\text{kg})$. Computes the total dose by multiplying the weight-based rate by the patient's body weight in kilograms.

Round to the nearest whole number: $\text{mL/hr}$. Aligns with IV pump programming that typically uses whole numbers for milliliters per hour.

Round to the nearest tenth: $\text{mL}$ to $0.1$. Provides precision in measuring oral liquids to the nearest tenth of a milliliter for accurate dosing.

Round to the nearest whole tablet. Ensures safe administration since tablets are indivisible unless scored, requiring whole unit dosing.

$1,\text{oz} = 30,\text{mL}$. Applies the approximate nursing conversion for fluid ounces to milliliters in dosage calculations.

$1,\text{tbsp} = 15,\text{mL}$. Utilizes the conventional conversion for tablespoons to milliliters in medication administration.

$1,\text{L} = 1000,\text{mL}$. Applies the metric volume conversion where one liter equals one thousand milliliters for fluid measurements.

$1,\text{kg} = 2.2,\text{lb}$. Uses the standard nursing approximation for converting patient weight between kilograms and pounds.

$1,\text{mg} = 1000,\text{mcg}$. Represents the metric conversion factor where one milligram equals one thousand micrograms in medication calculations.

$1,\text{g} = 1000,\text{mg}$. Reflects the metric system where one gram is equivalent to one thousand milligrams for dosage conversions.
