Free UNAR Infection Control Practices Questions and Answers 1 — Questions and Answers
Question 1: Which of the following are the components of the chain of infections?
- Mode of transmission, Host, Infectious agent, Portal of entry, Portal of exit
- Portal of entry, Infectious agent, Host, Reservoir, Portal of exit, Mode of transmission (Correct answer)
- Host, Infectious agent, Reservoir, portal of exit
- Portal of exit, Host, Infectious agent, Reservoir
Correct answer: Portal of entry, Infectious agent, Host, Reservoir, Portal of exit, Mode of transmission
The chain of infection describes the sequential process by which an infectious agent is transmitted from one host to another. Its components include the infectious agent (pathogen), reservoir (where it lives), portal of exit (how it leaves the reservoir), mode of transmission (how it travels), portal of entry (how it enters a new host), and a susceptible host. Breaking any link in this chain can prevent the spread of infection.
Question 2: Which of the following is an infection ,that is acquired in the hospital that was not present or incubating at the time of hospitalization?
- Primary infection
- Nosocomial infection (Correct answer)
- Community acquired infection
- Secondary infection
Correct answer: Nosocomial infection
A nosocomial infection, also known as a Hospital-Acquired Infection (HAI), is an infection that a patient acquires while receiving medical care in a healthcare facility. Crucially, these infections were not present or incubating at the time of the patient's admission. They often arise due to exposure to pathogens within the hospital environment or during medical procedures.
Question 3: Which of the following is the infection that only affects the immune-suppressed?
- Nosocomial infection
- Primary infection
- Opportunistic infection (Correct answer)
- Secondary infection
Correct answer: Opportunistic infection
An opportunistic infection is an infection that primarily affects individuals with compromised immune systems. Pathogens that are typically harmless to healthy individuals can cause severe disease when the host's immune defenses are weakened, such as in patients with HIV/AIDS, those undergoing chemotherapy, or transplant recipients. These infections "take advantage" of the opportunity presented by a suppressed immune response.
Question 4: Which of the following HAI’s are commonly seen in your Hospital?
- Urinary Tract Infection (UTI) (Correct answer)
- Surgical wound infection
- Respiratory tract infection (RTI)
- Skin infection
Correct answer: Urinary Tract Infection (UTI)
Urinary Tract Infections (UTIs) are among the most common hospital-acquired infections (HAIs), particularly in hospitalized patients. They are frequently associated with the use of indwelling urinary catheters, which can introduce bacteria into the urinary tract. Proper catheter care and early removal are crucial strategies to prevent these infections.
Question 5: Which population is most susceptible to Hospital acquired infections?
- Inpatients (Correct answer)
- Outpatients
- Nurses
- Doctors
Correct answer: Inpatients
Inpatients are the population most susceptible to Hospital-Acquired Infections (HAIs) because they are admitted to the hospital for medical care. Their susceptibility stems from factors such as prolonged exposure to healthcare environments, undergoing invasive procedures, having weakened immune systems due to illness, and the presence of multiple comorbidities.
