A nurse is preparing to administer a loading dose of phenytoin 10 mg/kg by IV bolus to a client who weighs 154 lb. Available is phenytoin50 mg/mL. How many mL should the nurse administer?
(Round the answer to the nearest whole number. Use a leading zero if it applies t use a trailing zero.)
The Correct Answer is ["14"]
To answer this question, the nurse needs to perform the following steps:
Convert the client's weight from pounds to kilograms by dividing it by 2.2. 154 lb / 2.2 = 70 kg.
Multiply the client's weight by the loading dose of phenytoin to get the total dose in milligrams. 70 kg x 10 mg/kg = 700 mg.
Divide the total dose by the concentration of phenytoin to get the volume in milliliters. 700 mg / 50 mg/mL = 14 mL.
Round the volume to the nearest whole number. The nurse should administer 14 mL of phenytoin by IV bolus.

Correct Answer is A
Explanation
Choice A rationale: The medication can be used for IV administration or IM administration as indicated in the label. Methylprednisolone is a corticosteroid that can be given intravenously to treat inflammatory conditions such as asthma, allergic reactions, rheumatoid arthritis, and multiple sclerosis. The medication label should indicate the route of administration, the concentration, the expiration date, and the storage conditions.
Choice B rationale: According to the label, the medication should not be used for more than 48 hours after reconstitution, and it should be stored in a refrigerator.
Choice C rationale: The vial contains multiple doses, and each dose should be withdrawn with a sterile syringe.
Choice D rationale: The medication should be reconstituted with bacteriostatic water for injection, not with 0.9% sodium chloride.
Correct Answer is ["67"]
Explanation
To solve this problem, the nurse needs to use the formula:
gtt/min = (Volume in mL x Drop factor in gtt/mL) / Time in min
Plugging in the given values, we get:
gtt/min = (100 x 10) / 15
gtt/min = 66.67
Rounding to the nearest whole number, we get:
gtt/min = 67
Therefore, the nurse should set the manual IV infusion to deliver 67gtt/min.
