1. Which of the following is an example of a zoonotic disease?

• A. The common cold
• B. Influenza (the flu)
• C. Malaria
• D. HIV/AIDS

Correct answer: B

Rationale: Rationale: A zoonotic disease is a disease that can be transmitted from animals to humans. Influenza is an example of a zoonotic disease as it can be transmitted from animals such as birds and pigs to humans. The common cold (option A) is caused by human rhinoviruses and is not considered a zoonotic disease. Malaria (option C) is transmitted through the bite of infected mosquitoes and is not considered a zoonotic disease. HIV/AIDS (option D) is caused by the human immunodeficiency virus and is not considered a zoonotic disease.

2. An IV drip delivers 40 drops per minute, each containing 1mg of medication. How many milligrams are administered in 3 hours (180 minutes)?

• A. 360mg
• B. 720mg
• C. 7,200mg
• D. 14,400mg

Correct answer: C

Rationale: Rationale: In this scenario, we first calculated the total number of drops administered in 3 hours by multiplying the drops per minute by the total number of minutes. Then, we converted the drops to milligrams by multiplying the total drops by the amount of medication in each drop. This method ensures an accurate calculation of the total amount of medication administered over the given time period.

3. What type of bond forms between elements when they share electrons?

• A. Covalent bond
• B. Ionic bond
• C. Metallic bond
• D. Hydrogen bond

Correct answer: A

Rationale: In a covalent bond, atoms share electrons, creating a strong attraction that holds them together

4. Which element is used in fire extinguishers to smother flames by displacing oxygen?

• A. Nitrogen
• B. Carbon dioxide
• C. Helium
• D. Argon

Correct answer: B

Rationale: Carbon dioxide extinguishes flames by depriving them of oxygen, preventing the chemical reaction that sustains the fire.

5. What is kwashiorkor, a protein deficiency disease, characterized by?

• A. Muscle wasting
• B. Night blindness
• C. Scurvy
• D. Rickets

Correct answer: A

Rationale: Rationale: Kwashiorkor is a type of severe acute malnutrition caused by a deficiency of dietary protein. It is characterized by symptoms such as edema (swelling due to fluid retention), skin lesions, an enlarged liver with fatty infiltrates, and muscle wasting. Muscle wasting is a key feature of kwashiorkor due to the body breaking down muscle tissue to obtain essential amino acids for vital functions. Night blindness (option B) is a symptom of vitamin A deficiency, scurvy (option C) is caused by a lack of vitamin C, and rickets (option D) is a condition resulting from a deficiency of vitamin D, calcium, or phosphate.

6. Which respiratory structure is responsible for the humidification and warming of inhaled air?

• A. Trachea
• B. Larynx
• C. Nasal passages
• D. Bronchi

Correct answer: c

Rationale: The correct answer is C: Nasal passages. The nasal passages are lined with mucous membranes that produce mucus to humidify and warm the inhaled air before it reaches the lungs. This process helps to protect the delicate lung tissues from drying out and becoming irritated. The trachea, larynx, and bronchi play important roles in the respiratory system, but specifically, the nasal passages are primarily responsible for humidifying and warming the air as it enters the body.
