A nurse is preparing to administer phenytoin. Which of the following information should the nurse identify as correct according to the medication label?

The medication is for IV administration.

The total amount available per container is 4 mL.

The nurse should avoid shaking the medication.

The medication should not be stored below 30 C(86 F)

Answer and Explanation

The Correct Answer is B

A. The medication is for IV administration: This cannot be assumed unless the label specifically states “for intravenous use.” Phenytoin comes in multiple formulations (oral suspension, tablets, IV), so route must be verified.
B. The total amount available per container is 4 mL: This is label-specific information. If the label indicates that each vial contains 4 mL, this is a factual and critical point to ensure accurate dosing.
C. The nurse should avoid shaking the medication: While some medications (e.g., suspensions) should not be shaken vigorously, phenytoin IV solution is not a suspension, and this instruction may not apply to all forms.
D. The medication should not be stored below 30°C (86°F): This is incorrect. Phenytoin should be stored at controlled room temperature, typically 20°C to 25°C (68°F to 77°F), and protected from excessive heat or cold.

Correct Answer is ["3.5"]

Explanation

Convert the client's weight from pounds to kilograms:
- 154 lb ÷ 2.2 lb/kg = 70 kg
Calculate the total dose required:
- 0.25 mg/kg × 70 kg = 17.5 mg
Determine the volume to administer:
- Given concentration: 5 mg/mL
- 17.5 mg ÷ 5 mg/mL = 3.5 mL
Rounding to the nearest tenth:
- The answer remains 3.5 mL

So the nurse should administer 3.5 mL of diltiazem IV injection.

which is 17.5 mg / 5 mg/mL = 3.5 mL. Rounding to the nearest tenth, the nurse should administer 3.5 mL of diltiazem IV injection.

Correct Answer is ["1"]

Explanation

To calculate the volume of medication to administer, use the formula: (desired dose / available dose) x available volume. Plug in the values: (50 mcg / 0.05 mg) x 1 mL = 1 mL. Round to the nearest whole number: 1 mL.
