cardiac scan
cardiac catheterization
treadmill stress test
doppler flow studies

hallux-
mano-
gnatho-
genu-

question 57
lou gehrigs disease is also known as:
cerebral palsy
amyotrophic lateral sclerosis
multiple sclerosis
parkinsons disease

• Question 55: Doppler Flow Studies use ultrasound to measure blood flow velocity. A cardiac scan (like an MRI or CT) gives anatomical images. Cardiac catheterization involves inserting a catheter into the heart. A treadmill stress test assesses heart function during exercise.
• Question 56: "Gnatho -" refers to the jaw. "Hallux -" is related to the big toe. "Mano -" pertains to the hand. "Genu -" is about the knee.
• Question 57: Lou Gehrig's disease is Amyotrophic Lateral Sclerosis (ALS). Cerebral Palsy is a motor disability. Multiple Sclerosis affects the central nervous system. Parkinson's Disease is a movement disorder.

Answer:

• Question 55: Doppler Flow Studies
• Question 56: gnatho -
• Question 57: Amyotrophic Lateral Sclerosis
