(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["20"]

To calculate the volume of medication to administer, use the formula: (desired dose / available dose) x available volume. Plug in the values: (25 mg / 6.25 mg) x 5 mL = 20 mL. Round to the nearest whole number: 20 mL.

Correct Answer is C

Explanation

Choice A rationale: Phenytoin is an anticonvulsant medication that is used to treat seizures. It can be given orally or intravenously, but the IV route requires careful preparation and monitoring. According to the medication label, the phenytoin is in form of an oral suspension hence it should be administered orally.

Choice B rationale: the total amount available per container is usually 5 mL not 4 mL. Choice C rationale: Phenytoin suspension should not be shaken, as it may cause the drug to precipitate. Shaking it could lead to inaccurate dosing.

Choice D rationale: The medication should also be stored at room temperature and protected from light.

Correct Answer is ["20.1"]

Explanation

To calculate the dosage of methylprednisolone, first convert the client's weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds.

The client weighs 184 pounds, which is approximately 83.64 kilograms (184 lb / 2.2).

Next, multiply the client's weight in kilograms by the dosage prescribed, which is 30 mg/kg.

This results in a total dosage of 2509.2 mg (83.64 kg * 30 mg/kg).

Finally, divide the total dosage by the concentration of the available medication to find out how many milliliters to administer.

The available medication is 125 mg/mL,

so you would administer 20.07 mL (2509.2 mg / 125 mg/mL).

Rounded to the nearest tenth, the nurse should administer 20.1 mL.
