Which formula is used to calculate the correct dosage of a medication based on a doctor's order? Desired Dose / Stock Dose x Volume of Stock Stock Dose / Desired Dose x Volume of Stock Desired Dose / Volume of Stock x Stock Dose Volume of Stock / Desired Dose x Stock Dose

Desired Dose / Stock Dose x Volume of Stock

What is the primary purpose of double-checking medication calculations? To verify the accuracy and safety of the dose To reduce the time spent on calculations To ensure compliance with pharmacy policies To increase the efficiency of drug administration

To verify the accuracy and safety of the dose

Which of the following best describes the concept of bioavailability in medication dosage? The proportion of the drug that enters circulation when introduced into the body The time it takes for a drug to reach its peak concentration The rate at which a drug is metabolized by the liver The amount of drug excreted unchanged in urine

The proportion of the drug that enters circulation when introduced into the body

What is the importance of understanding drug half-life in dosage calculations? To determine the frequency of dosing To calculate the initial dose To assess the drug's potency To evaluate the drug's side effects

To determine the frequency of dosing

What is the primary formula used to calculate dosage based on weight? Dosage = Weight × Dose per unit weight Dosage = Volume × Concentration Dosage = Weight / Volume Dosage = Concentration × Time

Dosage = Weight × Dose per unit weight

Which unit is commonly used to express medication dosages for infants? Milligrams per kilogram (mg/kg) Liters per hour (L/hr) Grams per liter (g/L) Millimoles per liter (mmol/L)

Milligrams per kilogram (mg/kg)

Which formula is used for calculating the correct dosage when the concentration is provided in mg/mL? Dosage (mg) = Volume (mL) × Concentration (mg/mL) Dosage (mg) = Volume (L) ÷ Concentration (mg/mL) Dosage (mg) = Concentration (mg/mL) ÷ Volume (mL) Dosage (mg) = Volume (mL) + Concentration (mg/mL)

Dosage (mg) = Volume (mL) × Concentration (mg/mL)

What is the formula for calculating the infusion rate in mL/hr for a given medication? Infusion Rate (mL/hr) = Total Volume (mL) ÷ Time (hr) Infusion Rate (mL/hr) = Total Volume (mL) × Time (hr) Infusion Rate (mL/hr) = Time (hr) ÷ Total Volume (mL) Infusion Rate (mL/hr) = Total Volume (mL) + Time (hr)

Infusion Rate (mL/hr) = Total Volume (mL) ÷ Time (hr)

In pediatric dosing, the Clark's rule is used. What is the formula for Clark's rule? Child's Dose = (Weight in lbs ÷ 150) × Adult Dose Child's Dose = (Weight in lbs ÷ 100) × Adult Dose Child's Dose = (Weight in lbs ÷ 200) × Adult Dose Child's Dose = (Weight in lbs ÷ 300) × Adult Dose

Child's Dose = (Weight in lbs ÷ 150) × Adult Dose

What must be considered when calculating medication doses for patients with renal impairment? Glomerular Filtration Rate (GFR) Patient's BMI Patient's blood type Patient's eye color

Glomerular Filtration Rate (GFR)

Which equation is used to calculate the Body Surface Area (BSA) for medication dosing? BSA (m²) = sqrt[(Height (cm) × Weight (kg)) ÷ 3600] BSA (m²) = (Height (cm) + Weight (kg)) ÷ 2 BSA (m²) = (Height (cm) × Weight (kg)) ÷ 1000 BSA (m²) = sqrt[(Height (cm) + Weight (kg)) ÷ 3600]

BSA (m²) = sqrt[(Height (cm) × Weight (kg)) ÷ 3600]

Which principle ensures that calculations for medication dosages are checked for accuracy? Double-check by two healthcare professionals Single verification by a nurse Rely on the physician's prescription only Use of automated software only

Double-check by two healthcare professionals

When adjusting doses for drugs with narrow therapeutic indices, what is crucial? Frequent monitoring of drug levels Adjust based on patient's diet Administer as a single daily dose Disregard patient's age

Frequent monitoring of drug levels

What is the formula to calculate dosage when given in mg/kg? Dosage = \[ rac{mg}{kg} \] imes weight Dosage = weight imes \[ rac{kg}{mg} \] Dosage = \[ rac{weight}{mg} \] imes \[ rac{kg}{mg} \] Dosage = \[ rac{kg}{weight} \] imes mg

Dosage = \[ rac{mg}{kg} \] imes weight

Which method helps ensure the accuracy of medication dosage calculations? Use mental math Verify calculations with a colleague Estimate the dose Skip double-checking

Verify calculations with a colleague

What is the primary reason for converting patient weight from pounds to kilograms? Most dosage calculations use kilograms Kilograms are easier to calculate Pounds are less accurate To simplify the process

Most dosage calculations use kilograms

What is the role of a 'dose conversion factor' in calculations? To simplify calculations To adjust dosages between different units To make estimates To speed up the process

To adjust dosages between different units
