Impaired hepatic function:
Causes a deficiency of intrinsic factor and pernicious anemia
Causes lactose intolerance
Causes gastric reflux
Causes blood drug levels to reach toxic levels
The Correct Answer is D
A. Causes a deficiency of intrinsic factor and pernicious anemia: Intrinsic factor is produced in the stomach, not the liver. Its deficiency leads to pernicious anemia.
B. Causes lactose intolerance: Lactose intolerance is due to lactase deficiency in the small intestine.
C. Causes gastric reflux: Gastroesophageal reflux is typically due to lower esophageal sphincter dysfunction.
D. Causes blood drug levels to reach toxic levels: The liver metabolizes drugs. Impaired hepatic function reduces drug clearance, leading to accumulation and potential toxicity.

Correct Answer is D
Explanation
A. Glucose is used up by the metabolizing nephron units: Nephrons do not metabolize all glucose; their role is to filter and reabsorb.
B. Glucose cannot be filtered: Glucose is a small molecule and is easily filtered by the glomerulus.
C. Glucose is converted to ammonia and excreted as urea: This describes protein metabolism, not glucose.
D. All filtered glucose is reabsorbed: In healthy kidneys, 100% of filtered glucose is reabsorbed in the proximal tubule, so none appears in urine unless blood levels are too high (e.g., diabetes).
Correct Answer is A
Explanation
A. Stomach: The esophagus carries food from the pharynx and empties it into the stomach via the lower esophageal sphincter.
B. Cecum: The cecum is part of the large intestine and is much further along in the digestive tract.
C. Common bile duct: This duct transports bile, not food. It is not directly connected to the esophagus.
D. Duodenum: The duodenum is the first part of the small intestine, which comes after the stomach, not directly after the esophagus.
