DaVita Patient Care Technician (PCT) 2025 – 400 Free Practice Questions to Pass the Exam

The indication of hemolysis in a patient can be observed when the blood in the venous line appears cherry red. Hemolysis refers to the breakdown of red blood cells, which can release hemoglobin into the plasma. This released hemoglobin can alter the color of the blood, leading to a bright red appearance due to the presence of oxyhemoglobin.

This is particularly significant during dialysis or when drawing blood, as it can be an important indicator of issues such as inappropriate vascular access, trauma during blood draws, or underlying hemolytic processes affecting the patient. Proper recognition of this coloration is crucial for the patient care technician in monitoring for potential complications.

Other indications, such as thick, dark blood, clear urine, or cold extremities, are not directly associated with hemolysis. Rather, they may relate to other physiological conditions and do not reflect the specific breakdown of red blood cells and their resultant effects on blood appearance. Understanding these nuances helps in accurate assessment and appropriate intervention when caring for patients.
