After completing a medication history the nurse is concerned that an older patient is at risk for drug toxicity. What did the nurse most likely assess in this patient? (Select all that apply.)
A) Takes medication for glaucoma
B) Experiences transient dizziness after taking anticonvulsant medication
C) Has blood work done every 3 months to check anticonvulsant drug levels
D) Takes digoxin for a cardiac dysrhythmia and carbamazepine for seizures once a day
E) Takes prescribed gabapentin for peripheral neuropathy with grapefruit juice every day
D, E
Feedback:
Anticonvulsant and digitalis preparations taken concurrently significantly increase the risk of toxicity from both drugs. Grapefruit increases the risk of toxicity when taken with an anticonvulsant medication. Medication for glaucoma does not increase the patient's risk of toxicity. Transient dizziness does not indicate toxicity. Having blood work done every 3 months would help reduce the risk of toxicity.
