Pharmacology Exam 1& 2 ATI Detailed Answer Key OB (FOR BEST REESULTS) <100% CORRECT> GRADED A+ | LATEST SOLUTIONS | Pharmacology Exam 1 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 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 Proportion
STEP 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 mcg
X = 0.125 mg
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
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.

Desired Over Have
STEP 1: What is the unit of measurement the nurse 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 mg/tablet
STEP 4: Should the nurse convert the units of measurement? Yes (mcg does not equal mg)
1 mg/1000 mcg = x mg/125 mcg
X = 0.125 mg
STEP 5: What is the quantity of the dose available? 1 tablet
STEP 6: Set up an equation and solve for X.
Desired x Quantity/Have = X
0.125 mg x 1 tablet/0.25 mg = X tab
0.5 = X
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 0.125 mg, it makes sense to administer 1/2 tab. The nurse should administer digoxin tab PO daily.
