Dosage Calculation R N Fundamentals Online Practice Assessment 3.0 Questions and Answers 100% Pass A nurse is preparing to administer codeine 20 mg PO every 6 hr PRN pain. Available is codeine oral solution 10 mg/ 5 mL. How many mL should the nurse administer per dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) ✔✔Answer: 10 mL Follow these steps for the Ratio and Proportion method of calculation: Step 1: What is the unit of measurement the nurse should calculate? mL Step 2: What is the dose the nurse should administer? Dose to administer = Desired 20 mg Step 3: What is the dose available? Dose available = Have 10 mg Step 4: Should the nurse convert the units of measurement? No Step 5: What is the quantity of the dose available? 5 mL Step 6: Set up an equation and solve for X. Have/Quantity = Desired/X 10 mg/ 5 mL = 20 mg/ X mL X mL = 10 mL Step 7: Round if necessary. Step 8: Determine whether the am ount to administer makes sense. If there are 10 mg/5 mL and the prescription reads 20 mg, it makes sense to administer 10 mL. The nurse should administer codeine oral solution 10 mL PO every 6 hr PRN pain. A nurse is preparing to administer eszopiclone 2, 000 mcg PO to a client. How many mg should the nurse administer? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) ✔✔Answer: 2 mg Follow these steps for the Ratio and Proportion method of calculation: Step 1: What is the unit of measurement the nurse should calculate? mg Step 2: What is the dose the nurse should administer? Dose to administer = Desired 2,000 mcg Step 3: What is the dose available? Dose available = Have 1 mg Step 4: Should the nurse convert the units of measurement? Yes (mcg does not equal mg) 1,000 mcg/1 mg = 2,000 mcg/X mg X mg = 2 mg Step 5: Round if necessary. Step 6: Determine whether the amount to administer makes sense. If the prescription reads 2,000 mcg and 1,000 mcg equals 1 mg, it makes sense to administer 2 mg. The nurse should administer eszopiclone 2 mg PO. A nurse is preparing to administer tobramycin 4 mg/kg/day IM divided in three equal doses to a patient who weighs 60 kg. Available is tobramycin 40 mg/mL. How many mL should the nurse administer per dose? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) ✔✔Answer: 2 mL Follow these steps for the Ratio and Proportion method of calculation: Step 1: What is the unit of measurement the nurse should calculate? mg Step 2: Set up an equation and solve for X. X = Dose per kg × Client's weight in kg X mg = 4 mg/kg × 60 kg X mg = 240 mg The dose is divided into three equal doses; therefore, divide X by 3. 240 mg = 80 mg3 Step 3: What is the unit of measurement the nurse should calculate? mL Step 4: What is the dose the nurse should administer? Dose to administer = Desired 80 mg Step 5: What is the dose available? Dose available = Have 40 mg Step 6: Sh ould the nurse convert the units of measurement? No Step 7: What is the quantity of the dose available? 1 mL Step 8: Set up an equation and solve for X. Have/Quantity = Desired/X 40 mg/1 mL = 80 mg/X mL X mL = 2 mL Step 9: Round if necessary. Step 10: Dete rmine whether the amount to administer makes sense. If there are 40 mg/mL and the prescription reads 4 mg/kg/day divided in three equal doses, it makes sense to administer 2 mL. The nurse should administer tobramycin 2 mL IM per dose. A nurse is preparing to administer meperidine 75 mg IM stat. Available is meperidine injection 100 mg/mL. How many mL should the nurse administer? (Round answer to nearest hundredth. Use a leading zero if it applies. Do not use a trailing zero.) ✔✔Answer: 0.75 mL
