Drugs with prominent hepatic and gastrointestinal effects in overdose are: ( Select one that does not apply)

Correct Answer: B

Rationale: The correct answer is B: Co-trimoxazole. Co-trimoxazole is primarily eliminated through the kidneys and does not have prominent hepatic or gastrointestinal effects in overdose. In contrast, A (Co-phenotrope), C (Co-proxamol), and D (Co-codamol) can cause significant hepatic and gastrointestinal effects in overdose due to the presence of opioids or paracetamol. Co-phenotrope contains diphenoxylate (an opioid), Co-proxamol contains dextropropoxyphene (an opioid), and Co-codamol contains codeine and paracetamol. Therefore, B is the correct answer as it does not apply to drugs with significant hepatic and gastrointestinal effects in overdose.

Correct Answer: C

Rationale: The correct answer is C: The body's food-processing system. The digestive system is responsible for processing and breaking down food into nutrients that can be absorbed by the body. This process involves various organs such as the stomach, intestines, and liver. It is not the body's breathing system (A), nervous system (B), or blood-transporting system (D) because those systems have different functions and are not directly involved in food processing.

Correct Answer: B

Rationale: The correct answer is B: Kidneys. The kidneys do not manufacture digestive juices. The liver produces bile to aid in digestion, the stomach produces gastric juices, and the pancreas produces digestive enzymes. The kidneys, however, are responsible for filtering blood, regulating fluid balance, and producing urine, not digestive juices. Therefore, option B is the correct answer.

Correct Answer: B

Rationale: The correct answer is B: pepsin. Pepsin is a digestive enzyme that breaks down proteins into smaller peptides. In this demonstration, the decrease in mass of the meat from 10g to 3g suggests protein digestion occurred. Bile (A) emulsifies fats, maltose (C) breaks down carbohydrates, and amylase (D) also breaks down carbohydrates, so they wouldn't cause the observed mass change.

Correct Answer: C

Rationale: The correct answer is C: pepsin. Pepsin is an enzyme produced in the stomach that breaks down proteins into peptides. It functions in an acidic environment, which is characteristic of the stomach. Amylase (A) breaks down carbohydrates, lipase (B) breaks down fats, and trypsin (D) breaks down proteins in the small intestine, not in structure W.
