Question
A 74-year-old man with COPD and BPH starting umeclidinium reports new difficulty starting urination and a sensation of incomplete bladder emptying. Which is the nurse's most appropriate action?
1Notify the provider — anticholinergic effects from umeclidinium can worsen BPH-related urinary retention; alternative therapy may be needed✓ Correct answer
2Discontinue all asthma/COPD medications and observe
3Encourage limiting fluids to less than 1 liter/day
4Reassure the client that this is unrelated to the medication
Explanation
Correct (2): Long-acting antimuscarinics (umeclidinium, tiotropium, aclidinium, glycopyrronium) can worsen urinary retention in BPH via M3 receptor blockade on the bladder. Cautioned/contraindicated when severe BPH or pre-existing retention. Provider may switch to a LABA-only regimen or LABA/ICS. (1) Real adverse effect. (3) Fluid restriction harms COPD. (4) Discontinuing all therapy risks COPD exacerbation.
In-depth explanation
Memory Tip LAMA + BPH = caution — anticholinergic relaxes detrusor and contracts internal sphincter, worsening retention. Screen BPH/glaucoma history before initiation.
Clinical scenario
Scenario 74-year-old male with COPD and BPH on umeclidinium 62.5 mcg daily × 2 weeks. New urinary hesitancy, weak stream, sensation of incomplete emptying.
Key concepts
LAMA cautions — Narrow-angle glaucoma, BPH/urinary retention, severe milk protein allergy (for some DPI carriers).
Urinary retention — Inability to empty bladder; worsened by anticholinergic medications in BPH.
