A patient is instructed to take 3/4 cup of a liquid medication daily. Convert this to milliliters.
A. 220 ml
Calculation: Ordered Dose = 3/4 cup Conversion:1 cup = 240 mL Volume in mL = Number of cups × 240 mL = 3/4 × 240 = 180 mL
B. 200 mL
Calculation: Ordered Dose = 3/4 cup Conversion:1 cup = 240 mL Volume in mL = Number of cups × 240 mL = 3/4 × 240 = 180 mL
C. 180 mL
Calculation: Ordered Dose = 3/4 cup Conversion:1 cup = 240 mL Volume in mL = Number of cups × 240 mL = 3/4 × 240 = 180 mL
D. 160 ml
Calculation: Ordered Dose = 3/4 cup Conversion:1 cup = 240 mL Volume in mL = Number of cups × 240 mL = 3/4 × 240 = 180 mL
Full Explanation
Calculation:
Ordered Dose = 3/4 cup
Conversion:1 cup = 240 mL
Volume in mL = Number of cups × 240 mL
= 3/4 × 240
= 180 mL
When using the formula method for medication calculations, what does 'D' represent?
A. Desired dose
Desired dose: In the formula D/H × Q, "D" represents the desired dose prescribed for the patient. It is the amount of medication that the nurse aims to administer, which is essential for accurate and safe dosing.
B. Quantity
Quantity: Quantity ("Q") refers to the amount of the medication form available, not the desired dose.
C. Dose on hand
Dose on hand: The dose on hand ("H") represents the concentration or strength of the available medication, not the prescribed amount.
D. Dilution factor
Dilution factor: Dilution factor is used when adjusting concentrations for administration but is not represented by "D" in the standard formula method.
