Question 1
When performing medical handwashing, what is the minimum recommended duration for
vigorous rubbing with soap and water?
A) 5–10 seconds
B) 15–20 seconds
C) 30–45 seconds
D) 1 minute
E) 2 minutes
Correct Answer: B) 15–20 seconds
Rationale: Standard medical handwashing requires at least 15 to 20 seconds of vigorous
rubbing to create the friction necessary to remove transient microorganisms. Longer
durations are required for surgical scrubs, but 15–20 seconds is the baseline for clinical
practice.
Question 2
During handwashing, which position should the nurse maintain to prevent contaminated water
from flowing back toward the clean areas?
A) Hands held higher than the elbows
B) Hands held at the same level as the elbows
C) Hands held lower than the elbows
D) Hands folded in front of the chest
E) Hands resting on the edge of the sink
Correct Answer: C) Hands held lower than the elbows
Rationale: Water should flow from the least contaminated area (the forearms/elbows) to the
most contaminated area (the hands). Keeping the hands lower than the elbows ensures that
gravity carries microorganisms and soap residue away from the cleaner upper arms and
into the sink.
Question 3
Which motion is most effective for removing microorganisms from the skin surfaces during
handwashing?
A) Back-and-forth scrubbing
B) Firm rubbing in a circular motion
C) Gentle patting with a towel
D) Rapid vertical strokes
E) Light rinsing with hot water
Correct Answer: B) Firm rubbing in a circular motion
Rationale: Firm, circular motions create the friction needed to mechanically loosen dirt and
, 2
microbes from the various grooves and folds of the skin on the palms, backs of hands, and
fingers.
Question 4
A nurse is preparing to wash their hands before a procedure. What is the standard protocol
regarding jewelry?
A) Rings with stones may be kept on if covered by gloves
B) All jewelry, including watches and rings, should be removed
C) Only the wedding band should be kept on
D) Jewelry only needs to be removed for sterile procedures
E) Bracelets can remain if they are pushed up the arm
Correct Answer: B) All jewelry, including watches and rings, should be removed
Rationale: Microorganisms can become trapped under rings and watches, making effective
hand hygiene impossible. Removing jewelry allows the nurse to clean all skin surfaces
thoroughly.
Question 5
When performing a bed bath, which technique should the nurse use to promote venous return?
A) Short, rapid strokes toward the feet
B) Long, firm strokes from distal to proximal areas
C) Circular motions over the joints only
D) Gentle patting with a damp cloth
E) Light strokes from the shoulder to the wrist
Correct Answer: B) Long, firm strokes from distal to proximal areas
Rationale: Applying firm pressure while moving from the distal part of an extremity (the
hand or foot) toward the proximal part (the shoulder or hip) assists in pushing blood back
toward the heart, thereby improving circulation and venous return.
Question 6
A patient is confined to bed but is able to wash their own face and chest. The nurse assists by
washing the patient’s back and feet. This type of bath is classified as a:
A) Complete bed bath
B) Self-help bed bath
C) Partial bath
D) Bag bath
E) Towel bath
Correct Answer: B) Self-help bed bath
Rationale: A self-help bath is used for patients who are confined to bed but can manage
much of the bathing themselves with some assistance from the nurse for hard-to-reach
areas like the back and feet.

Question 7
A nurse is using commercially prepared, pre-moistened washcloths that do not require rinsing to
bathe a patient. This is known as a:
A) Sponge bath
B) Towel bath
C) Bag bath
D) Tub bath
E) Complete bed bath
Correct Answer: C) Bag bath
Rationale: A bag bath utilizes a package of soft cloths pre-soaked in a no-rinse
surfactant/cleanser. It is efficient, reduces the risk of cross-contamination from basins, and
is gentler on the skin of elderly patients.
Question 8
Which patient would be categorized as "moderately dependent" regarding hygiene?
A) A patient who requires no assistance at all
B) A patient who requires help from another person and the use of a specialized device
C) A patient who can bathe themselves but needs the nurse to set up the supplies
D) A patient who is comatose and cannot participate
E) A patient who only needs help washing their hair
Correct Answer: B) A patient who requires help from another person and the use of a
specialized device
Rationale: The levels of dependency range from independent (0) to totally dependent (4).
Moderate dependency (Level 2 or 3 depending on the scale used) typically implies the need
for both human assistance and assistive equipment.
Question 9
When performing foot care for a diabetic patient, which action is a priority safety measure?
A) Cutting the nails in a rounded shape
B) Applying lotion between the toes to prevent dryness
C) Cutting the nails straight across
D) Soaking the feet in hot water for 30 minutes
E) Using a sharp razor to remove calluses
Correct Answer: C) Cutting the nails straight across
Rationale: Diabetic patients are at high risk for infection and slow healing. Cutting nails
straight across prevents ingrown toenails and accidental skin nicks. Lotion should never be
applied between the toes as the moisture can lead to skin breakdown and fungal growth.
Question 10
A nurse is providing oral care for an unconscious patient. Which of the following is an essential
safety precaution?
