ADULT MEDI CAL SURGICAL DOSAGE CALCULATION ATI DOSAGE CALCULATION PN ADULT MEDICAL SURGICAL PROCT ORED ASSESSMENT 3.1 COMPLETE QUESTIONS AND CORRECT ANSWERS|ALREADY GRADED A+ 1) The physician orders metoprolol 25 mg, b.i.d for one week initially, then decrease to metoprolol 12.5 mg PO t.i.d. for a patient with high blood pressure. Available is metoprolol 12.5 mg/tab. How many tablets should the patient initially receive per dose for the first week? 2 Points ANSWER Since the physician prescribed b.i.d., the patient has to take 25 mg twice per day. 25 mg x 2 = 50 mg/day This means the patient has to take 50 mg/day x 7 days = 350 mg/week To count how many tablets the patient sho uld receive, we can divide the total dose per week by the available dose per tablet. That is 350 mg/12.5 mg = 28 tablets. 2)A client with Raynaud’s disease has orders to receive pentoxifylline (Trental) 600 mg by mouth daily. The label reads 400mg/tablet. How many tablet(s) should the nurse give for each dose? 2 Points ANSWER To count how many tablets the patient should receive, we can divide the daily dose by the available dose per tablet. That is 600 mg/400 mg = 1 ½ tablets. 3) A patient is to receive mep hobarbital (Mebaral) 150 mg by mouth four times daily for seizure disorder. Available is mephobarbital (Mebaral) 300 mg/5mL. How many mL of the drug will the client receive in a 24-hour period? 4 Points ANSWER Since the patient has to take the drug four ti mes, we have to calculate 150 mg by 4 which gives us 600 mg daily. Then dividing that by the available dose, we can get the mL of drug the client will receive in a 24-hour period. That is 600 mg/300 mg = 2 x 5 mL = 10 mL ADULT MEDI CAL SURGICAL DOSAGE CALCULATION ATI DOSAGE CALCULATION PN ADULT MEDICAL SURGICAL PROCT ORED ASSESSMENT 3.1 COMPLETE QUESTIONS AND CORRECT ANSWERS|ALREADY GRADED A+ 4) The physician gives the followin g order for a client with chronic biventricular heart failure: ‘Digoxin 0.025mg/kg IV bolus’ NOW!’ If the patient weighs 176 lbs, how many mg of digoxin should the nurse give this patient? 4 Points ANSWER First, we have to convert the weight of the patient from lbs to kg. 1 kg is equivalent to 2.205 lbs. Therefore, 176 lbs/2.205 lbs/kg = 79.82 kg. Multiplying that by the dose of Digoxin per kg, we get 79.82 kg x (0.025 mg/kg) = 1.9955 mg or 2.00 mg 5) The physician orders amoxicillin/clavulanate potassium (Augmentin) 500 mg PO, b.i.d. for ten days. The label reads 125mg/5ml. How many milliliters (mL) of the drug should the client receive per dose? 4 Points ANSWER We can calculate the dose by dividing the pr escribed dose by the available dose per volume of drug. That is 500 mg/125mg = 4 x 5 mL = 20 mL 6) The physician has ordered heparin 2000 units subcutaneously twice daily. The label reads 5000 units/ml. How many mL will the nurse administer? 2 Points ANSWE R To calculate the volume needed to be administered, we can divide the prescribed units by the available units/mL. That is 2000 units/5000 units = 0.4 mL/dose. Since it has to be taken twice daily, we get 0.4 mL x 2 = 0.8 mL daily. 7) Order: ‘Lorazepam 2mg IM STAT for status epilepticus. The vial of lorazepam contains 20mg/10ml. How much will the nurse draw into the syringe to administer the prescribed dose? 4 Points
