Certified Ambulatory Perianesthesia Nurse (CAPA) Practice Exam

What condition should a perianesthesia nurse notify the anesthesia provider about before assisting with a Bler block?

1. Horner's syndrome

2. Fibromyalgia

3. Sickle cell disease

4. Osteoarthritis

The correct answer is: Sickle cell disease

Notifying the anesthesia provider about sickle cell disease before assisting with a block is crucial due to the potential complications that can arise from this condition. Sickle cell disease is a genetic blood disorder characterized by the production of abnormal hemoglobin, leading to distorted, sickle-shaped red blood cells. These cells can cause blockages in small blood vessels, resulting in vaso-occlusive crises, which can occur during episodes of pain or due to stress in the body. When performing a regional anesthesia procedure such as a Bler block, there is a risk of triggering such complications in patients with sickle cell disease. The altered blood flow and potential for thrombosis can lead to an increased risk of serious issues, including pain exacerbation, organ damage, or even stroke. Hence, preemptive notification allows the anesthesia provider to take necessary precautions, such as adjusting the technique or monitoring protocols, to ensure the safety of the patient. Conditions like Horner's syndrome, fibromyalgia, and osteoarthritis may have implications for patient care and comfort, but they do not present the same immediate risk of complications during a regional anesthesia procedure that sickle cell disease does.
