COC Anatomy and Pathophysiology for Coding 2 — Questions and Answers
Question 1: Chronic obstructive pulmonary disease (COPD) is primarily characterized by:
- Persistent airflow limitation that is not fully reversible (Correct answer)
- Acute, fully reversible bronchoconstriction
- Restrictive lung pattern with reduced lung volumes
- Increased diffusion capacity
Correct answer: Persistent airflow limitation that is not fully reversible
COPD is defined by persistent, not fully reversible airflow limitation, distinguishing it from asthma, which is typically reversible.
Question 2: Which layer of the gastrointestinal wall contains blood vessels, lymphatics, and the submucosal nerve plexus?
- Submucosa (Correct answer)
- Mucosa
- Muscularis propria
- Serosa
Correct answer: Submucosa
The submucosa layer of the GI wall contains blood vessels, lymphatics, and Meissner's (submucosal) nerve plexus, which regulates secretion.
Question 3: A patient is diagnosed with deep vein thrombosis (DVT) of the popliteal vein. The popliteal vein is located in which body region?
- Behind the knee (Correct answer)
- In the upper thigh
- In the groin
- In the lower leg calf
Correct answer: Behind the knee
The popliteal vein runs through the popliteal fossa, located posterior to (behind) the knee joint.
Question 4: The gallbladder stores and concentrates which digestive fluid?
- Bile (Correct answer)
- Pancreatic juice
- Gastric acid
- Chyme
Correct answer: Bile
The gallbladder stores and concentrates bile produced by the liver; bile is released into the duodenum to aid in the digestion and absorption of fats.
Question 5: Which nerve is most commonly compressed in carpal tunnel syndrome, causing numbness and tingling in the hand?
- Median nerve (Correct answer)
- Ulnar nerve
- Radial nerve
- Musculocutaneous nerve
Correct answer: Median nerve
Carpal tunnel syndrome results from compression of the median nerve as it passes through the carpal tunnel at the wrist.
Question 6: Osteoporosis is defined as a decrease in:
- Bone mineral density, increasing fracture risk (Correct answer)
- Bone marrow production of red cells
- Calcium absorption in the intestine only
- Osteoclast activity in the periosteum
Correct answer: Bone mineral density, increasing fracture risk
Osteoporosis is characterized by reduced bone mineral density and deterioration of bone microarchitecture, substantially increasing the risk of fragility fractures.
