Question 1 of 5
Phenytoin (Dilantin) suspension 200 mg is prescribed for a client with epilepsy. The suspension contains 125 mg/5 ml. How much solution should the nurse administer? Record your answer using a whole number.
Correct Answer: 8 mL
Rationale: The document's explanation is incorrect.
To find the volume: (200 mg / 125 mg) * 5 mL = 8 mL. The suspension is 125 mg per 5 mL, so 200 mg requires 8 mL. The explanation's calculation (200 / 125 = 1.6 mL) and subsequent rounding to 8 mL are inconsistent with the proportion method and clinical practice. The correct volume, based on the proportion, is exactly 8 mL, which aligns with the answer provided.
