A nurse is preparing to administer phenytoin 200 mg PO to a client. Available is phenytoin oral suspension 125 mg/5 mL. How many mL should the nurse administer? (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 ["8"]

To calculate the dose of phenytoin oral suspension, the nurse should use the following formula:

Dose (mL) = Desired dose (mg) / Concentration (mg/mL) x Volume (mL)

Plugging in the values from the question, we get:

Dose (mL) = 200 mg / 125 mg/5 mL x 5 mL

Simplifying the equation, we get:

Dose (mL) = 8 mL

Correct Answer is ["30"]

Therefore, 2 tbsp = 2 x 15 mL = 30 mL.

The nurse should administer 30 mL of magnesium hydroxide PO.

Correct Answer is ["1.8"]

Explanation

To calculate the correct dosage of gentamicin for a client who weighs 154 lb, the nurse needs to perform the following steps:

- Convert the client's weight from pounds to kilograms by dividing by 2.2. 154 lb / 2.2 = 70 kg.

- Multiply the client's weight in kilograms by the prescribed dose of 1 mg/kg. 70 kg x 1 mg/kg = 70 mg.

- Divide the total dose in milligrams by the concentration of the gentamicin solution, which is 40 mg/mL. 70 mg / 40 mg/mL = 1.75 mL.

Round the final answer to the nearest tenth of a milliliter. The nurse should administer 1.8 mL of gentamicin IM to the client.
