1. When washing your hands, which of the following is the most
important action to prevent the spread of infection?
A) Using hot water
B) Applying lotion immediately after
C) Rubbing your hands together vigorously for at least 20 seconds
D) Drying your hands on a paper towel
Answer: C
Rationale: Friction is the most critical element in mechanical
handwashing to remove microorganisms. The CDC recommends
rubbing hands vigorously with soap and water for at least 15 to 20
seconds. Hot water can damage the skin, and lotion should only be
applied after hands are completely dry if facility policy permits.
2. A patient has a Foley catheter. The PCA notices that the urinary
drainage bag is resting on the floor. What is the correct action?
A) Leave it there to prevent backflow
B) Hang the bag on the side rail of the bed
C) Place the bag below the level of the bladder but off the floor
D) Raise the bag above the patient's abdomen to increase flow
Answer: C
Rationale: The drainage bag must always be kept below the level of
the bladder to prevent backflow of urine into the bladder, which can
cause infection. However, it must never rest on the floor due to the
high risk of bacterial contamination. Hanging it on the side rail is
unsafe if the bed is lowered.
3. Which of the following is considered a Standard Precaution?
A) Wearing a mask only when a patient is coughing
B) Wearing gloves when handling blood, body fluids, and non-intact
skin
, C) Placing a patient in a negative pressure room
D) Wearing a gown only when entering a patient's room
Answer: B
Rationale: Standard Precautions apply to all patients regardless of
diagnosis. They include hand hygiene and the use of Personal
Protective Equipment (PPE) like gloves when there is a potential for
contact with blood, body fluids, secretions, excretions, and non-
intact skin.
4. When taking a patient's blood pressure, the PCA should ensure
the cuff is deflated completely and the patient's arm is supported at
heart level. Why is arm placement important?
A) To prevent the patient's arm from getting tired
B) To ensure an accurate reading
C) To make it easier to find the brachial artery
D) To prevent the cuff from rolling
Answer: B
Rationale: If the arm is above heart level, the blood pressure reading
will be falsely low. If the arm is below heart level, the reading will be
falsely high. Supporting the arm at heart level ensures the most
accurate measurement.
5. A patient is on contact precautions for Clostridioides difficile (C.
diff). Which type of PPE is strictly required upon entering the room?
A) N95 respirator
B) Gown and gloves
C) Face shield
D) Shoe covers
Answer: B
Rationale: C. diff is spread through spores in the feces that can
contaminate the environment. Contact precautions require a gown
and gloves to prevent the PCA from touching contaminated surfaces
and transferring the spores to other patients.
