9 What is the main challenge of antibiotic resistance?

A. Increased vaccine efficacy
B. Limited treatment options
C. Higher hospital costs
D. Improved hygiene practices
Explanation

Antibiotic resistance leads to limited treatment options for infections, making them harder to manage.

D. Handwashing before surgery
Explanation

Maintaining a sterile field is crucial for preventing infections during surgical procedures.

11 What is the primary goal of infection control in healthcare?

A. Improving patient comfort
B. Reducing hospital costs
C. Preventing infections
D. Increasing staff efficiency
Explanation

The main goal of infection control is to prevent infections in patients and healthcare workers.

12 What type of waste is considered biohazardous?

A. Regular trash
B. Contaminated sharps
C. Recyclable materials
D. Food waste
Explanation

Contaminated sharps pose a risk of infection and must be disposed of as biohazardous waste.

13 What is the significance of cohorting patients?

A. To increase hospital capacity
B. To provide better food
C. To minimize infection transmission
D. To reduce staff workload
Explanation

Cohorting patients with similar infections helps limit the spread of pathogens among different patient groups.

14 Which infection control measure is most effective in preventing HAIs?

A. Routine cleaning
B. Use of antiseptics
C. Hand hygiene
D. Patient education
Explanation

Hand hygiene is the single most effective measure to prevent the transmission of infections in healthcare settings.

15 What is the rationale behind using PPE?

A. To look professional
B. To reduce infection risk
C. To comply with regulations
D. To save costs
Explanation

PPE provides a protective barrier against infectious agents, reducing the risk of transmission.

16 What is the role of patient education in infection control?

A. To ensure compliance with regulations
B. To empower patients with knowledge
C. To reduce hospital stays
D. To improve hospital ratings
Explanation

Educating patients about infection prevention enhances their understanding and compliance with safety practices.

17 When should healthcare workers perform hand hygiene?

A. Only before meals
B. Only after using the restroom
C. Before and after patient contact
D. Only when hands are visibly dirty
Explanation

Hand hygiene should be performed before and after any patient contact to prevent infection transmission.

18 What is an example of an airborne infection?

A. Chickenpox
B. Hepatitis
C. Strep throat
D. C. difficile
Explanation

Chickenpox is transmitted through airborne particles, while the others have different routes of transmission.

19 Which of the following is a key factor in controlling outbreaks?

A. Increasing hospital beds
B. Monitoring infection rates
C. Enhancing meal quality
