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.
Question 2 of 5
A client with a history of seizures is being admitted to the emergency room after experiencing a partial seizure. Which question would be most appropriate for the nurse to ask the client?
Correct Answer: C
Rationale: Asking about the last dose of seizure medication identifies potential non-adherence, a common cause of breakthrough seizures.
Question 3 of 5
A clinic nurse is performing a physical assessment on a client who has systemic lupus erythematosus (SLE). Which of the following findings should the nurse expect?

Correct Answer: B
Rationale: A CD4+ T cell count below 200 cells/mm defines AIDS, indicating severe immune suppression and susceptibility to opportunistic infections.
