Ati Pharmacology Exam1Detailed Answer Key OB 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</br>STEP 1: What is the unit of measurement the nuse should calculate? tablet <br/>STEP 2: What is the dose the nurse should administer?

Yes (mcg does not equal mg) <br/>1 mg/1000 mcg = x mg/125 mcg</br>X = 0.125 mg</br>STEP 5: What is the quantity of the dose available? 1 tablet <br/>STEP 6: Set up an equation and solve for X. <br/>Have/Quantity = Desired/X <br/>0.25 mg/1 tablet = 0.125 mg/X tablet <br/>X = 0.5 <br/>STEP 7: Round if necessary. <br/>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.
