1. A nurse is caring for a client who has heart failure and a prescription for digoxin 125 mcg PO daily. Available is
digoxin PO
... [Show More] 0.25 mg/tablet. How many tablets should the nurse administer per dose? (Round the answer to the
nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
0.5 tablet(s)
Correct Rationale: Ratio and ProportionSTEP 1: What is the unit of measurement the nuse should
calculate? tablet
STEP 2: What is the dose the nurse should administer? Dose to
administer= Desired 125 mcg
STEP 3: What is the dose available? Dose available =
Have 0.25
STEP 4: Should the nurse convert the units of measurement? Yes (mcg
does not equal mg)
1 mg/1000 mcg = x mg/125 mcgX = 0.125 mgSTEP 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
0.25 mg/1 tablet = 0.125 mg/X tablet
X = 0.5
STEP 7: Round if necessary.
STEP 8: Reassess to determine
whether the amount to administer makes sense. If there are 0.25 mg/tab and the provider
prescribed 0.025 mg, it makes sense to administer 1/2 tab. The nurse should administer
digoxin tab PO daily.
