Answer :
Final answer:
The correct usage of a reflex hammer is demonstrated by striking the patient's relaxed knee and observing the knee-je_rk reflex. The reflex indicates the health of the nervous system. So the correct answer is Option B.
Explanation:
The correct technique for a nurse to use a reflex hammer is demonstrated through option b) Striking the patient's knee with the hammer and observing the reflex. In practice, a nurse or healthcare professional has the patient relax their leg completely. The healthcare professional then uses the reflex hammer to gently tap the patellar tendon, located slightly below the kneecap. If the technique is performed correctly, this induces a knee-je_rk reflex caused by an automatic response from the nervous system. Reflex tests play an essential role in physical examinations as they can indicate the health of the nervous system.
