Practice Question
A nurse is preparing to administer phenytoin oral suspension. Which of the following information should the nurse identify as correct, according to the medication label? (Refer to the medication label below to answer the question.)
Answer Choices:
Correct Answer:
Shake the bottle well before each use.
Rationale:
🔹 Phenytoin oral suspension is a suspension, meaning the medication is not evenly dissolved and particles may settle over time. To ensure accurate dosing, shaking the bottle well before each use is essential to evenly distribute the medication.
🔹 Most oral suspensions must be shaken to avoid administering a subtherapeutic or toxic dose due to uneven distribution.
🔹 Storage in a refrigerator is not recommended for phenytoin; it should be kept at room temperature to avoid precipitation or changes in viscosity.
🔹 While phenytoin is often available as 125 mg/5 mL, a strength of 125 mg/mL is extremely high and incorrect for routine use.
🔹 The total volume of the bottle (e.g., 250 mL) is not the key safety instruction for administration, unlike shaking the suspension.
