Which one of the following is not a causative agent for infection?
- A.
Protozoa
- B.
Spores
- C.
Parasites
- D.
Viruses
Correct Answer
B. SporesExplanation
Spores are not a causative agent for infection because they are simply a dormant form of certain microorganisms, such as bacteria or fungi, that enable them to survive in unfavorable conditions. While spores can germinate and give rise to active infectious agents, they themselves do not directly cause infections. On the other hand, protozoa, parasites, and viruses are all capable of causing infections in humans and other organisms.Rate this question:

. A condition commonly found in reservoirs is:
- A.
Moisture.
- B.
Light.
- C.
Density.
- D.
Air.
Correct Answer
A. Moisture.Explanation
Reservoirs are bodies of water that are used to store and supply water for various purposes. Moisture is a common condition found in reservoirs because they are filled with water. Reservoirs are designed to hold and retain water, so it is natural for them to have moisture present. Other conditions such as light, density, and air may also be present in reservoirs, but moisture is the most common and essential condition for a reservoir to function properly.Rate this question:

An example of a human reservoir for infectious agents is:
- A.
a. Drainage from a wound.
- B.
b. The respiratory tract.
- C.
c. Urine and feces.
- D.
d. Saliva and vomitus.
Correct Answer
B. b. The respiratory tract.Explanation
The correct answer is b. The respiratory tract. The respiratory tract serves as a human reservoir for infectious agents because it is the pathway through which respiratory infections are transmitted. Infectious agents such as viruses and bacteria can be present in respiratory secretions, such as mucus and saliva, and can be expelled into the air through coughing, sneezing, or talking. This allows for easy transmission of respiratory infections from person to person.Rate this question:

Portals of exit from the human reservoir include:
- A.
Gastrointestinal and urinary tracts.
- B.
Intact skin.
- C.
Dirty hands.
- D.
Nose, mouth, and anus.
Correct Answer
D. Nose, mouth, and anus.Explanation
The portals of exit from the human reservoir refer to the routes through which infectious agents can leave the body. The gastrointestinal and urinary tracts can serve as portals of exit because they can contain pathogens that are excreted in feces and urine. Intact skin can act as a barrier to prevent the escape of pathogens, so it is not considered a portal of exit. Dirty hands can carry pathogens from one person to another, but they are not a direct portal of exit. On the other hand, the nose, mouth, and anus are openings in the body that can allow infectious agents to be expelled, making them the correct answer.Rate this question:

Which of the following is a mode of transmission?
- A.
Radioactivity
- B.
Body fluids
- C.
Fomites
- D.
Canned food
Correct Answer
C. FomitesExplanation
Fomites are objects or surfaces that can become contaminated with infectious organisms and can serve as a mode of transmission for diseases. This can include items such as clothing, utensils, doorknobs, and furniture. When a person comes into contact with a contaminated fomite and then touches their face or mouth, they can introduce the infectious organisms into their body. Therefore, fomites can play a role in the spread of diseases.Rate this question:

Portals of entry include all but which one of the following?
- A.
Anatomical openings
- B.
Intact skin
- C.
Open wounds
- D.
Needle sticks
Correct Answer
B. Intact skinExplanation
The question asks for the exception among the given options regarding portals of entry. Portals of entry refer to the routes through which pathogens can enter the body. Anatomical openings, open wounds, and needle sticks are all examples of portals of entry as they provide direct access for pathogens. However, intact skin acts as a protective barrier and does not allow pathogens to enter the body easily, making it the exception among the given options.Rate this question:

Immunocompetence can protect a susceptible host.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Immunocompetence refers to the ability of the immune system to effectively respond to and defend against pathogens. A susceptible host is someone who is at risk of getting an infection or disease. Therefore, if a host is immunocompetent, their immune system is strong and capable of protecting them from pathogens, reducing their susceptibility to infections. Hence, the statement "Immunocompetence can protect a susceptible host" is true.Rate this question:
-
- 11.
The host can be protected in which one of the following ways?
- A.
Protecting the immune systems of both patients and healthcare workers
- B.

In certain situations, isolation may be achieved by:
- A.
Moving the patient to the far side of a double room.
- B.
Cohorting with another patient infected by the same microorganism.
- C.
Eliminating hand washing and toileting facilities, which only serve to spread infection.
- D.
Installing a separate room air conditioner.
Correct Answer
B. Cohorting with another patient infected by the same microorganism.Explanation
Cohorting with another patient infected by the same microorganism can help achieve isolation because it reduces the risk of spreading the infection to other patients. By keeping patients with the same infection together, healthcare providers can implement specific infection control measures for that particular microorganism, such as using dedicated equipment and following strict protocols. This helps in preventing the transmission of the infection to other patients and reducing the overall spread of the disease.Rate this question:
