MISSED MEDICATION DOSES

Whenever a medication dose has been missed, the nurse should contact the physician to clarify what is best for the patient.

When a medication dose is missed eg. the patient is off the unit, the nurse should not assume that the patient can wait until the next dose is due. The decision about the missed dose belongs to the physician.

V. Some Helpful Hints: Exam candidates may bring one nursing drug reference book and a calculator (extra batteries recommended) to use during the exam. Example: Mosby’s Nursing Drug Reference by Linda Skidmore-Roth; Cost: approx. $38.00. No cell phones may be brought into the exam area or used during the test.

VI. Sample Conversions and Calculations : The problems below represent the types of calculations that will be presented on the nursing pharmacology exam. The answers are found at the end of this review guide.

7/

Conversions:

a. 2 tsp = _____ mL f. 2 oz = _____ mL b. 450 mcg = _____ mg g. 150 lbs = _____ kg c. .048 gm = _____ mg h. 65 kg = _____ lbs d. 475 mg = _____ gm i. 4.1 mg = _____ mcg e. 3 tablespoons = _____ mL j. 2.5 inches = _____ cm

Calculations:

  1. A child is to receive amoxicillin 50 mg po. The medication in oral suspension is labeled 125 mg per 5 ml. How many mls should the child receive?
  2. The liquid medication label reads 100 mg per 2 ml. The order is for the patient to receive 200 mg of the medication. How many mls will be administered?
  3. The patient is to receive digoxin 0.25 mg IV. Digoxin is in prefilled syringes of 0.5 mg per 2 mls. How many mls will be administered by syringe?
  4. The physician orders dynapen 125 mg po stat. The bottle is labeled 25 mg per ml. How many mls should be given?
  5. Penicillin G sodium for injection contains 250,000 units per ml. How many units are there in 3.5 mls?
  6. The doctor orders 1000 ml of D 5 W every 6 hours. How many mls per hour should the patient receive?
  7. Calculate the drip rate for an IV of D 5 ½ NS to run at 20 ml per hour using a microdrip set (60 gtts per ml).
  8. The patient is to receive Keflex 1 gm P.O. On hand is Keflex 250 mg per tablet. How many tablets should be administered?
  9. Garamycin comes in a concentration of 80 mg per 2ml. How many mls would be needed for a dose of 40 mg?
  10. The physician orders 1 liter of NS every 8 hours. How many mls per hour should the patient receive? Using macrodrip tubing (15 gtts per ml) what is the flow rate in gtts per minute?
