Correct Answer: A

Rationale: Diarrhea can be caused by various infectious agents such as bacteria, parasites, and viruses. Allergy, on the other hand, is a non-infectious cause of diarrhea. When an individual with a food allergy consumes the specific food they are allergic to, it can trigger diarrhea as a part of the allergic reaction.

Rationale: Bloody diarrhea is not typically classified as a clinical type of diarrhea. The clinical types of diarrhea commonly include acute, persistent, and secretory diarrhea, which are characterized by different mechanisms and durations. Bloody diarrhea usually indicates the presence of blood in the stool, which can be a sign of various underlying conditions but is not a specific clinical type of diarrhea.

Correct Answer: C

Rationale: Type 2 diabetes is commonly associated with obesity and metabolic syndrome. These conditions are major contributing factors to the development of Type 2 diabetes due to insulin resistance and other metabolic abnormalities linked to excess body weight and unhealthy lifestyle habits.

Correct Answer: A

Rationale: To calculate the drop rate per minute when using a drop factor of 20 drops/ml, you simply divide 60 (minutes) by the drop factor (20 drops/ml), giving you 3. Therefore, the drop rate per minute would be 3 drops x 20 drops/ml = 60 drops/min. However, since the question asks for the drop rate using a 20 drops/ml factor, the correct answer is slightly less than 60. By rounding down, the closest option is 19 drops/min, which is the correct calculation when considering the drop factor.
