D) Peroxide contamination

Quizplus · Accepted Answer

The positive reagent strip reaction for blood indicates the presence of either hemoglobin or myoglobin. However, since the patient experienced an adverse reaction during surgery, it is more likely that the blood in the urine is due to hemoglobin, which is commonly released from damaged red blood cells in the bloodstream. Myoglobin, on the other hand, is released from damaged muscle tissue and is less likely to be present in the urine of a patient who experienced an adverse surgical event. Choice C is incorrect as RBCs would not cause a positive reagent strip reaction for blood, but would be detected separately on the urine microscopy portion of the urinalysis. Choice D is incorrect as peroxide contamination would not cause a positive reagent strip reaction for blood.
