2. Which of the following methods is the best method for determining nasogastric tube placement in the stomach?

• A. X-ray
• B. Observation of gastric aspirate
• C. Testing of pH of gastric aspirate
• D. Placement of external end of tube under water

3. Each of the following is a function of the liver except one. Which one is the exception?

• A. Regulatory control of nutrients in the bloodstream
• B. Conversion of monosaccharides to triglycerides
• C. Breakdown of polysaccharide glycogen into glucose
• D. Oxidation of digestive end products to provide energy

Correct answer: B

Rationale: The correct answer is B. The liver does not convert monosaccharides to triglycerides; instead, it converts monosaccharides to glucose or glycogen. Choice A is correct because the liver plays a role in regulating the levels of various nutrients in the bloodstream. Choice C is correct as the liver breaks down stored glycogen into glucose to maintain blood sugar levels. Choice D is correct as the liver oxidizes digestive end products to provide energy. Therefore, only choice B is incorrect as the liver does not convert monosaccharides to triglycerides.
