Question

The nurse reviews the phenytoin level of a client who is taking phenytoin. The nurse notes that the plasma drug level is 9 mcg/mL. What should the nurse anticipate to be prescribed for the client?

a. Increase the present dosage.

b. Decrease the present dosage.

c. Maintain the current dosage.

d. Switch to a different anticonvulsant.

Answer 1

Phenytoin is a medication used to treat seizures. A plasma drug level of 9 mcg/mL is subtherapeutic. The nurse should anticipate a dosage increase to achieve a therapeutic level.

Step-by-step explanation:

Phenytoin is a medication used to treat seizures. The therapeutic range for phenytoin levels is generally considered to be between 10 to 20 mcg/mL. A level of 9 mcg/mL is subtherapeutic, meaning it is below the desired range. Therefore, the nurse should anticipate that the client may be prescribed an increase in the current dosage of phenytoin to achieve a therapeutic level.

Answer 2

The nurse anticipate to increase the present dosage to be prescribed for the client .

Therefore, correct option is a. Increase the present dosage.

Step-by-step explanation:

A plasma drug level of 9 mcg/mL for phenytoin is below the therapeutic range (usually 10-20 mcg/mL). To achieve optimal therapeutic effects, the nurse should anticipate an increase in the present dosage (a). This adjustment aims to bring the drug level within the therapeutic range, ensuring adequate seizure control while minimizing the risk of adverse effects.

Phenytoin has a narrow therapeutic range, and maintaining a consistent therapeutic level is crucial for its effectiveness. Regular monitoring of drug levels helps healthcare providers make dosage adjustments to optimize therapeutic outcomes while avoiding toxicity.

Therefore, correct option is a. Increase the present dosage.
