1. How can preserving skin integrity impact the circular chain of infection?
- A. Host
- B. Reservoir
- C. Mode of transmission
- D. Portal of entry
Correct answer: D
Rationale: Preserving skin integrity plays a key role in breaking the chain of infection by eliminating the portal of entry for pathogens. When the skin is intact, it acts as a natural barrier that prevents pathogens from entering the body. By maintaining skin integrity through proper hygiene and wound care, the risk of infection is significantly reduced, disrupting the cycle of infection transmission.
2. Which of the following actions will most likely lead to a break in the sterile technique for respiratory isolation?
- A. Opening the patient’s window to the outside environment
- B. Turning on the patient’s room ventilator
- C. Opening the door of the patient’s room leading into the hospital corridor
- D. Failing to wear gloves when administering a bed bath
Correct answer: D
Rationale: Failure to wear gloves during a bed bath can potentially introduce pathogens, compromising the sterile technique necessary for respiratory isolation. Proper hand hygiene and personal protective equipment are crucial to prevent the transmission of infectious agents in such settings.
3. Which of the following patients is at greater risk for contracting an infection?
- A. A patient with leukopenia
- B. A patient receiving broad-spectrum antibiotics
- C. A postoperative patient who has undergone orthopedic surgery
- D. A newly diagnosed diabetic patient
Correct answer: A
Rationale: Leukopenia, characterized by low white blood cell count, significantly reduces the body's ability to fight infections. Patients with leukopenia are at a higher risk of contracting infections due to compromised immune defenses.
4. What is required for effective hand washing?
- A. Soap or detergent to promote emulsification
- B. Hot water to destroy bacteria
- C. A disinfectant to increase surface tension
- D. All of the above
Correct answer: A
Rationale: To effectively wash hands, soap or detergent is essential as they help emulsify fats and oils, allowing them to be rinsed away. Hot water alone cannot effectively destroy bacteria, and a disinfectant is not typically required for routine hand washing.
5. After routine patient contact, how long should hand washing last at least?
- A. 30 seconds
- B. 1 minute
- C. 2 minutes
- D. 3 minutes
Correct answer: A
Rationale: Proper hand washing for 30 seconds is recommended after routine patient contact as it effectively removes pathogens. This duration ensures thorough cleaning without excessive time consumption, promoting infection control and prevention.
