In which situation is hand hygiene with soap and water preferred over an alcohol-based hand rub?
Before donning sterile gloves for a procedure.
After removing gloves.
When hands are visibly soiled.
After touching a patient's intact skin.
The Correct Answer is C
A. Before donning sterile gloves, an alcohol-based hand rub is generally acceptable if hands are not visibly soiled, as it effectively reduces microbial load.
B. After removing gloves, an alcohol-based hand rub is typically sufficient unless hands are contaminated with visible dirt or bodily fluids.
C. Hand hygiene with soap and water is preferred when hands are visibly soiled or contaminated with dirt, blood, or other bodily fluids. Soap and water mechanically remove debris and reduce microbial load more effectively than alcohol-based rubs in these situations.
D. After touching a patient’s intact skin, alcohol-based hand rub is usually sufficient, as the risk of transmission is lower and hands are not visibly dirty.

Correct Answer is B
Explanation
A. There is no indication of equipment malfunction; the nurse is able to hear Korotkoff sounds, which indicates proper functioning of the sphygmomanometer and stethoscope.
B. The first faint, clear tapping sound heard when inflating and then slowly deflating the cuff represents the systolic blood pressure. In this scenario, the systolic pressure is 110 mm Hg, indicating the pressure at which the heart is pumping blood into the arteries.
C. The diastolic blood pressure is recorded when the sounds disappear, not when they first appear. Therefore, 110 mm Hg is not the diastolic value.
D. While a cuff that is too loose can affect accuracy, the presence of clear tapping sounds suggests that the cuff fit is adequate for obtaining a measurement.
Correct Answer is A
Explanation
A. The nurse should rub the alcohol-based hand sanitizer over all surfaces of the hands, including around rings and between fingers, to ensure thorough coverage and effective microbial reduction.
B. Alcohol-based hand sanitizer does not require rinsing with water; rinsing would reduce its effectiveness.
C. The recommended duration for rubbing hands with alcohol-based sanitizer is 15–30 seconds, not specifically 20 seconds as with soap and water, but the key is complete coverage rather than timing alone.
D. Hands do not need to be dried with a towel after using alcohol-based sanitizer; the product evaporates naturally. Using a reusable towel could introduce contaminants.
