Question

1) A nurse practitioner orders 0.4 ounces (oz) of liquid Tylenol every 4-6 hr. for a temperature greater than 101.5°F. You have a measuring cup in milliliter (mL) calibrations. How many mL will you administer to the patient? (1 oz = 30 mL)

2)An older physician orders Aspirin grain X (gr 10), by mouth (po), for a patient with a headache. The pharmacist provides you with Aspirin 325 mg tablets (tab). How many tab(s) will you administer to the patient? (1 gr = 60 mg)

3)An ER physician orders Amoxicillin suspension, 0.25 grams (g), by mouth (po) immediately (STAT) for a 9-year-old patient diagnosed with otitis media. The pharmacist provides you with Amoxicillin suspension: 125 mg/ 5 mL. How many teaspoon(s) (t) will you administer to the patient? (1 t = 5 mL)

Answer 1

1) 1 oz = 30 mL

Volume in ml = 0.4*30 = 12 ml

2) 1 gr = 60 mg

No of tablets = 10 gr* 60 mg/gr * 1/325 tablet/mg

                = 10*60*1/325 = 1.846 tablets

3)
     1 t = 5 ml

      5 ml = 125 mg

total amount of drug required = 0.25 grams

Volume of drug must be taken = 0.25*1000*5/125   = 10 ml

No of teaspoon(s) must be taken = 10/5 = 2
