Patellar Reflex Assessment Techniques

In this video, Sarah from Registered Nurse RN demonstrates how to check the patella deep tendon reflex, which involves assessing the L2 to L4 spinal nerves. The process includes locating the tendon just below the kneecap, supporting the knee, and tapping briskly to observe the lower leg's extension. The video concludes with an invitation to explore other videos on deep tendon reflexes and to subscribe to the channel.

Which spinal segments are assessed when checking the patella deep tendon reflex?

• L4 to L6

• L2 to L4

• L1 to L3

• L3 to L5

What is the first step in locating the patellar tendon for the reflex test?

• Check the thigh muscle

• Locate the kneecap

• Find the ankle

• Identify the hip joint

How should the patient's leg be positioned to make the patellar tendon more prominent?

• Flex the leg

• Bend the knee

• Rotate the leg

• Extend the leg

What is the purpose of placing your hand behind the knee during the reflex test?

• To stabilize the foot

• To support the knee

• To apply pressure

• To measure the reflex

What is the expected response when the patellar tendon is tapped briskly?

• The knee bends

• The thigh muscle contracts

• The foot curls inward

• The lower leg extends outward

What should you do if you want to learn about other deep tendon reflexes?

• Read a textbook

• Watch more videos

• Consult a doctor

• Attend a workshop
