A nurse is assisting with the care of a postoperative client who is receiving a unit of packed RBCs. Which data should the nurse recognize as an indication of a septic reaction to the blood transfusion?

Choice A reason: Isoniazid is an antitubercular drug that can cause urine to turn dark yellow or brown, not red-orange.

Choice B reason: Metoprolol is a beta-blocker that can cause urine to turn blue-green, not red-orange.

Choice C reason: Rifampin is an antitubercular drug that can cause urine to turn red-orange, as well as other body fluids such as saliva, sweat, and tears.

Choice D reason: Furosemide is a diuretic that can cause urine to become more concentrated and darker in color, but not red-orange.

Choice A: This is incorrect because feeling bloated after the procedure is not a reason to call the doctor. Feeling bloated after a colonoscopy is normal due to air being introduced into the colon during the procedure. The client can relieve bloating by passing gas or walking.

Choice B: This is correct because making arrangements for a ride home indicates an understanding of the procedure. The client will receive sedation during a colonoscopy, which can impair their judgment and coordination. The client should not drive or operate machinery until fully recovered from sedation.

Choice C: This is incorrect because eating a light breakfast the morning of the procedure indicates a lack of understanding of the procedure. The client should have nothing by mouth after midnight before a colonoscopy, unless instructed otherwise by the provider. The client should follow a clear liquid diet and take bowel preparation agents as prescribed before the procedure.

Choice D: This is incorrect because having a sore throat from the breathing tube indicates a lack of understanding of the procedure. The client will not have a breathing tube during a colonoscopy, as it does not involve intubation or ventilation. The client may have a mouth guard or bite block to protect their teeth and prevent biting on the endoscope.
