◉A nurse is preparing to administer 2 Tbsp of ibuprofen to a client.
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: Answer: 30 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 2 Tbsp
Step 3: What is the dose available? Dose available = Have 1 mL
Step 4: Should the nurse convert the units of measurement? Yes
(Tbsp does not equal mL)
1 Tbsp / 15 mL = 2 Tbsp / X mL
X mL = 30 mL
Step 5: Round if necessary.
, Step 6: Determine whether the amount to administer makes sense. If
the prescription reads 2 Tbsp and 1 Tbsp equals 15 mL, it makes
sense to administer 30 mL. The nurse should administer ibuprofen
30 mL.
◉A nurse is preparing to administer prednisone 50 mg PO to a
patient. Available is prednisone 20 mg/tablet. How many tablets
should the nurse administer?
(Round answer to nearest tenth. Use a leading zero if it applies. Do
not use a trailing zero.). Answer: Answer: 2.5 tablets
Follow these steps for the Ratio and Proportion method of
calculation:
Step 1: What is the unit of measurement the nurse should calculate?
tablet(s)
Step 2: What is the dose the nurse should administer? Dose to
administer = Desired 50 mg
Step 3: What is the dose available? Dose available = Have 20 mg
Step 4: Should the nurse convert the units of measurement? No
Step 5: What is the quantity of the dose available? 1 tablet
Step 6: Set up an equation and solve for X.
Have/Quantity = Desired/X
20 mg/ 1 tablet = 50 mg / X tablet(s)
