Anaesthesia · Analgesia: NSAIDs
Sample itemWhy might ketorolac be avoided in a patient with active gastrointestinal bleeding?
Original practice item, not a recalled exam question. Nothing here is recorded.
The answer and the reasoning
A. It inhibits platelet cyclooxygenase and impairs aggregation
Ketorolac is a nonselective NSAID that inhibits platelet thromboxane production and can increase bleeding risk while also causing gastrointestinal and renal toxicity.
Option by option
A. It inhibits platelet cyclooxygenase and impairs aggregation (correct)
Correct. Reduced thromboxane-mediated platelet function can worsen bleeding.
B. It antagonises opioid receptors
NSAIDs do not antagonise opioid receptors.
C. It causes profound respiratory depression
Respiratory depression is an opioid effect.
D. It blocks neuromuscular transmission
Neuromuscular transmission is not its target.
