1. The word hormone is derived from the Greek 'hormao' meaning 'I excite or arouse.' Hormones communicate this effect through their unique chemical structures recognized by specific receptors on their target cells, their patterns of secretion, and their concentrations in the general or local circulation. Which of the following is NOT a function of hormones?

• A. Producing new offspring
• B. Promoting growth and enhancing beauty
• C. Maintaining body temperature
• D. Fighting infections

Correct Answer: A

Rationale: Hormones play a crucial role in various bodily functions such as regulating metabolism, growth, and maintaining homeostasis. However, producing new offspring involves reproductive processes controlled by other systems in the body, not directly by hormones.

2. A child of 3 years has been admitted to your pediatric ward. The doctor gave a provisional diagnosis of respiratory tract infection. After careful assessment and history, he gave a final diagnosis of lower respiratory infection. Which of the following signs will confirm the diagnosis?

• A. Cough
• B. Fever
• C. Inability to lie supine
• D. Inability to eat

Correct Answer: C

Rationale: Inability to lie supine is a specific sign of lower respiratory infection. This condition can cause discomfort or difficulty in breathing when lying flat, leading to a preference for an upright or semi-upright position. While cough and fever are common symptoms of respiratory infections, the inability to lie supine is more indicative of lower respiratory involvement.

3. Which of the following is an indication of lower respiratory infection?

• A. Cough
• B. Fever
• C. Inability to lie supine
• D. Shortness of breath

Correct Answer: C

Rationale: Inability to lie supine is a significant indication of lower respiratory infection. This symptom often occurs due to breathing difficulties and discomfort experienced by individuals with lower respiratory infections, such as pneumonia or bronchitis. It can be caused by lung inflammation, consolidation, or fluid buildup in the lungs, making lying flat uncomfortable or difficult. Monitoring a patient's ability to lie flat can provide valuable information about the severity and progression of a lower respiratory infection.

4. Which of the following is not a clinical type of diarrhea?

• A. Acute diarrhea
• B. Bloody diarrhea
• C. Persistent diarrhea
• D. Secretory diarrhea

Correct Answer: B

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.

5. Which of the following are not infectious causes of diarrhea?

• A. Allergy
• B. Bacteria
• C. Parasite
• D. Virus

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.
