• Stimulants

• Anticholinergics

• NSAIDs

A patient with rheumatoid arthritis is not responding to NSAIDs. What is a logical next step in drug therapy?

• Prescribe a triptan

A patient with Alzheimer’s disease is started on donepezil. How would you explain the rationale for this therapy to the patient’s family?

• It increases dopamine to improve movement.

• It inhibits acetylcholinesterase to increase acetylcholine levels, which may help with memory and cognition.

• It blocks sodium channels to prevent seizures.

• It reduces inflammation in the joints.

A patient with a history of seizures is prescribed phenytoin. What considerations should be made regarding potential drug interactions and side effects?

• Phenytoin has minimal drug interactions and few side effects.

• Phenytoin can interact with many drugs and may cause side effects such as gingival hyperplasia and ataxia.

• Phenytoin is only used for muscle spasms and has no relevance to seizures.

• Phenytoin is safe in all populations without monitoring.
