The practical nurse (PN) is helping with the care plan for a client who is taking the nonsteroidal anti-inflammatory drug ketorolac for painful back muscle spasms. What intervention should the PN include in the client’s care plan?

Observe the client for development of involuntary movements of the lips and tongue.

Administer the medication at least 30 minutes before the client’s meals.

Assess the skin daily for areas of ecchymosis or other signs of bleeding.

Ensure peak and trough serum levels are collected with the third dose of medication.
