TEST BANK CALCULATION OF DRUG DOSAGES

What strength of drug would be administered if 6 g of active ingredient is reconstituted with sterile water to a total volume of 300 ml? 2% strength 0.5% strength 20% strength 50% strength - correct answer-2% strength. 6 g of active ingredient in 300 ml represents 2 g for every 100 ml, which is a 2% solution. Normal saline in solution with albuterol is known as the solvent. True False - correct answer-True. A solution contains an active drug, which is the solute dissolved in a solvent, such as sterile water or normal saline. When calculating drug dosages based on a patient's weight in kilograms, a respiratory therapist can use the BSA nomogram to convert from pounds to kilograms. True False - correct answer-False. The nomogram used to determine body surface area (BSA) combines height and weight in a single measurement to determine a patient's overall body size. If a drug dosage requires a specific number of units per patient weight in kilograms, the factor-label method should be used to convert the patient's weight from the English system to the metric system. How many mg of active ingredient are there in 3 mL of a 0.083% solution of albuterol? - correct answer-3 x .83mg = 2.49 mg (convert 0.083g to .83mg) A metaproterenol sulfate unit dose contains 2.5 mL of a 0.6% solution. How many milligrams of active ingredient are present in this unit dose? - correct answer-2.5 x 6mg = 15 mg (convert 0.6g to 6mg) If a drug order is written for 0.25 mg/kg of body weight, what dosage would be administered to a patient weighing 88 lb? - correct answer-88/2.2=40, 40 x .25 = 10mg The physician order reads "Administer 5 mg metaproterenol via inhalation route with a small volume nebulizer." How many milliliters of a 1% solution should be used? - correct answer-5 x .1 = 0.5 mL A dosage of 4 mg of morphine sulfate is ordered for a patient. How many milliliters of the morphine solution needs to be taken from a vial of the medicine that contains 10 mg/ml? - correct answer-4 x .10 = 0.4 mL
