Practice Questions

Question 1

Which of the following actions is the most effective way to prevent healthcare-associated infections (HAIs)?

A. Wearing gloves for all patient interactions
B. Using hand sanitizer before and after patient care
C. Placing all patients in isolation rooms
D. Administering antibiotics prophylactically

Answer:
B. Using hand sanitizer before and after patient care

Explanation:
Hand hygiene, including the use of hand sanitizer or washing with soap and water, is the single most effective way to prevent healthcare-associated infections. While wearing gloves (option A) is important, it does not replace the need for proper hand hygiene. Placing all patients in isolation (option C) is unnecessary and impractical, and administering antibiotics prophylactically (option D) can contribute to antibiotic resistance rather than preventing infections effectively.

Question 2

What is the first step a nurse should take when a patient begins to fall?

A. Attempt to stop the fall by pulling the patient upright.
B. Move quickly to get assistance from another staff member.
C. Guide the patient to the floor while protecting their head.
D. Let the patient fall to avoid nurse injury.

Answer:
C. Guide the patient to the floor while protecting their head.

Explanation:
When a patient begins to fall, the priority is to protect the patient from injury. Guiding the patient to the floor while supporting their head helps minimize impact and prevent further harm. Attempting to stop the fall by pulling the patient upright (option A) may cause injury to both the nurse and the patient. Moving to get assistance (option B) or allowing the patient to fall (option D) are not safe or effective actions.

Question 3

Which personal protective equipment (PPE) is required when caring for a patient on airborne precautions?

A. Gloves and gown
B. Surgical mask
C. N95 respirator mask
D. Face shield

Answer:
C. N95 respirator mask

Explanation:
An N95 respirator mask is required when caring for a patient on airborne precautions, as it filters small particles that may carry infectious agents such as tuberculosis, measles, or varicella. Gloves and gowns (option A) are used for contact precautions, while a surgical mask (option B) is appropriate for droplet precautions. A face shield (option D) may be used for droplet precautions but is not sufficient alone for airborne pathogens.
