NURS 4073; ATI Dosage Calculation Fundamentals Proctored Exam

Question 19. A nurse is preparing to administer codeine 20 mL oral solution to a patient. How many tsp should the nurse administer? (Round answer to nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) Answer: 4 tsp Follow these steps for the Ratio and Proportion method of calculation: Step 1: What is the unit of measurement the nurse should calculate? tsp Step 2: What is the dose the nurse should administer? Dose to administer = Desired 20 mL Step 3: What is the dose available? Dose available =Have 1 tsp Step 4: Should the nurse convert the units of measurement? Yes (mL does not equal tsp) 5 mL / 1 tsp = 20 mL / X tsp X tsp = 4 tsp Step 5: Round if necessary. Step 6: Determine whether the amount to administer makes sense. If the prescription reads 20 mL and 5 mL equals 1 tsp, it makes sense to administer 4 tsp. The nurse should administer codeine oral solution 4 tsp Question 20.

Dose to administer = Desired20 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? 1 mL Step 6: Set up an equation and solve for X. Have/Quantity = Desired/X 10 mg/ 1 mL = 20 mg / X mL X mL = 2 mL Step 7: Round if necessary.
