How is reflex activity assessed during a physical examination?

• A. By observing the patient's walking pattern
• B. Using a stethoscope to listen to heart sounds
• C. Using a reflex hammer to elicit responses
• D. By checking the patient's pulse rate

Answer: (C)

Reflex activity is assessed using a reflex hammer to elicit responses from the patient's muscles and nervous system. This tool allows the practitioner to strike specific tendons at various locations on the body, such as the knee or Achilles tendon. When the hammer strikes the tendon, it sends a signal to the spinal cord, which in turn sends a signal back to the muscle to contract, resulting in a visible reflex response. Assessing reflexes provides valuable information about the integrity of the nervous system, including any potential lesions or dysfunctions along the reflex pathways. It helps to evaluate both the central and peripheral nervous systems and allows healthcare providers to identify abnormalities that may suggest underlying neurological conditions. Other methods of assessment, such as observing a patient's walking pattern or checking pulse rate, can provide useful information about overall health and circulation but do not specifically assess reflex activity. The use of a stethoscope to listen to heart sounds pertains to cardiovascular assessment rather than neurological evaluation. Therefore, using a reflex hammer is the specialized method specifically designed to measure and evaluate reflex activity.
