HAI Quiz: Can You Stop CAUTI, CLABSI & VAP?

1. Which type of urinary catheter material is preferred to reduce biofilm formation in CAUTI prevention?

Latex

Silicone or hydrogel-coated

Plastic

Rubber

2. The most common portal of entry for VAP pathogens is:

Bloodstream

Gastrointestinal tract aspiration

Urinary system

Skin flora only

3. Central line placement should be performed using ultrasound guidance primarily to:

Reduce insertion time

Decrease mechanical complications and infection risk

Allow faster blood draws

Reduce cost of placement

4. Which sign or symptom is NOT typical of CAUTI?

Dysuria

Suprapubic tenderness

Bradycardia

Cloudy urine

5. How should the urinary catheter drainage bag be positioned relative to the bladder?

Above bladder level

At the same level as bladder

Below bladder level

Leg-bag only, never bedside bag

6. Which intervention directly reduces bacterial colonization in the oropharynx for VAP prevention?

Nasogastric feeding

Oral chlorhexidine rinse

Prophylactic antibiotics

Frequent suctioning only

7. The most significant modifiable risk factor for VAP is:

Patient age

Duration of mechanical ventilation

Underlying disease severity

Hospital size

8. Which catheter securement method is recommended to prevent CLABSI?

Sutures only

Transparent dressing with stabilization device

Tape only

No securement needed

9. Spontaneous awakening and breathing trials are part of which HAI prevention bundle?

CAUTI bundle

CLABSI bundle

VAP bundle

Surgical site infection bundle

10. What does the acronym CLABSI stand for?

Catheter-linked bloodstream infection syndrome

Central line-associated bloodstream infection

Contaminated line bacterial sepsis incident

Central laboratory-associated bacterial source infection

11. Which of the following is the primary risk factor for developing CAUTI?

Duration of catheterization

Patient age over 65

Female gender

Antibiotic use

12. Hand hygiene compliance is most critical at which moment for CLABSI prevention?

Before touching the patient

Before aseptic procedures

After exposure to body fluids

At shift change

13. Which organism is the most common causative agent of CAUTI?

Staphylococcus aureus

Escherichia coli

Pseudomonas aeruginosa

Candida albicans

14. What is the recommended frequency for central line dressing changes?

Daily

Every 2 days

Every 7 days or when soiled or loose

Weekly only

15. Oral hygiene with chlorhexidine is primarily aimed at reducing which HAI?

CAUTI

CLABSI

VAP

Surgical site infection

16. Which intervention is part of the VAP bundle to reduce aspiration risk?

Head of bed elevation 30–45 degrees

Supine positioning

Continuous sedation

Nasogastric tube placement

17. VAP is most likely to develop after how many days of mechanical ventilation?

Within 24 hours

After 48 hours

After 7 days

Only after 2 weeks

18. Which aseptic technique is critical during central line insertion to prevent CLABSI?

Sterile gloves and mask only

Full sterile precautions including sterile field and drape

Standard precautions with hand hygiene

Clean gloves and antiseptic wipe

19. CLABSI most commonly originates from which source?

Infusion fluid contamination

Microorganisms from the patient's skin or catheter hub

Healthcare worker hand contamination

Environmental air in the ICU

20. What is the most effective intervention to prevent CAUTI?

Daily catheter cleaning with antiseptic

Prompt removal of unnecessary catheters

Routine catheter replacement every 7 days

Antibiotic prophylaxis for all patients
