Contraindications to performing suprapubic bladder aspiration include which condition?

• A. Colostomy
• B. Distended urinary bladder
• C. Uncorrected thrombocytopenia or bleeding diathesis
• D. Normal coagulation profile

Answer: (C)

Bleeding risk with invasive bladder procedures is the critical factor here. Suprapubic bladder aspiration involves piercing the abdominal wall and entering the bladder, so any condition that impairs normal hemostasis raises the chance of significant bleeding, hematoma, or other hemorrhagic complications. Uncorrected thrombocytopenia or a bleeding diathesis compromises the body's ability to form clots and stop the bleeding after the needle passes through tissues, making this procedure contraindicated until hemostasis is corrected.

Colostomy itself does not introduce a bleeding risk that would universally prohibit the procedure, though care may be needed around the stoma site. A distended urinary bladder is actually a reason to perform decompression, not a contraindication. A normal coagulation profile indicates adequate clotting capability, so there is no contraindication from a bleeding standpoint.
