The nurse administers ophthalmic timolol to a client with glaucoma. The client routinely takes carvedilol, spironolactone, and ibuprofen daily. Which medication(s) should the nurse withhold? Select all that apply.
Explanation & Rationale
Rationale: A. Any antianxiety medications: Antianxiety medications are not contraindicated with ophthalmic timolol. Unless they directly impact heart rate or blood pressure significantly, they are generally safe to continue in clients with glaucoma using topical beta blockers. B. Over-the-counter oral antipyretics: Oral antipyretics like acetaminophen are not known to interact adversely with timolol. These medications can be used safely unless otherwise contraindicated for specific patient conditions like liver disease. C. Nonsteroidal antiinflammatory drugs: NSAIDs such as ibuprofen, when used long-term with beta blockers like timolol or carvedilol, may blunt the antihypertensive effect and increase renal risk, especially in clients on diuretics like spironolactone. This triple combination increases the chance of nephrotoxicity. D. Other beta-adrenergic blocker agents: Using timolol with systemic beta blockers like carvedilol increases the risk of bradycardia, hypotension, and heart block. Though timolol is topical, systemic absorption can still occur, requiring caution when combining with other beta-blockers. E. Oral and subcutaneous anticoagulants: There is no direct contraindication between timolol and anticoagulants. Unless the client has bleeding risks associated with other therapies or conditions, concurrent use is generally acceptable.
