CERTIFICATION EXAM 2026/2027:
150 VERIFIED PRACTICE QUESTIONS
WITH ANSWERS & RATIONALES (DC
HEALTH BOARD OF NURSING HHA
PREP)
Role & Scope of Practice
1. What is the primary role of a Home Health Aide (HHA)?
A. Diagnose medical conditions
B. Prescribe medications
C. Provide supportive personal care and assistance with activities of daily living
(ADLs)
D. Perform independent nursing assessments
Answer: C
Rationale: An HHA primarily assists clients with ADLs, personal care, comfort, safety,
and other assigned supportive services. HHAs do not independently diagnose
conditions, prescribe medications, or perform duties reserved for licensed healthcare
professionals.
2. A client asks the HHA for advice about which foods to eat for a new diabetes
diagnosis. What should the aide do?
A. Provide a list of recommended foods
B. Explain that dietary advice must come from the healthcare provider or dietitian
and report the question to the supervising nurse
C. Tell the client to search the internet for a diabetes diet
D. Adjust the client’s meal plan based on the aide’s knowledge
Answer: B
Rationale: Home health aides are not qualified to provide dietary advice or counseling.
This is outside the scope of practice. The aide should report the client’s question to the
supervising nurse or dietitian. Providing dietary advice without proper training could
harm the client and is a violation of professional boundaries.
,3. An HHA is asked by a client to perform a task that is outside the HHA’s scope
of practice. What should the HHA do?
A. Perform the task anyway to please the client
B. Politely refuse and explain the task is outside the scope of practice, then report the
request to the supervisor
C. Ask another aide to do it instead
D. Tell the client to do it themselves
Answer: B
Rationale: HHAs must know their scope of practice and refuse tasks that are not within
it. Performing tasks outside the scope of practice can endanger the client and place the
HHA at risk for legal action. The nurse should be notified so that a licensed person can
perform the task.
Infection Control
4. What is the single most effective way to prevent the spread of infection in a
home health setting?
A. Wearing gloves at all times
B. Frequent and thorough handwashing
C. Using bleach to clean all surfaces
D. Isolating the patient in their room
Answer: B
Rationale: Hand hygiene (handwashing) is the most effective single method for
reducing the spread of infection. Gloves are not a substitute for hand hygiene, and
isolation and bleach are not appropriate as a universal first-line measure.
5. When washing your hands before providing client care, how long should you
scrub your hands with soap and water?
A. 5 seconds
B. 10–15 seconds
C. At least 20 seconds
D. 1 minute
Answer: C
Rationale: The CDC recommends scrubbing hands with soap and water for at least 20
seconds to effectively remove pathogens. Shorter durations are insufficient for proper
hand hygiene.
,6. Which action best ensures proper disinfection of a reusable blood pressure
cuff between patients in a home setting?
A. Wipe with soap and water only
B. Spray with hydrogen peroxide and air dry
C. Use an EPA-registered disinfectant wipe and allow to dry completely
D. Soak in bleach solution for 10 minutes
Answer: C
Rationale: EPA-registered disinfectant wipes are specifically designed for medical
equipment and effectively kill pathogens when used according to manufacturer
instructions. Soap and water clean but do not disinfect; hydrogen peroxide may
damage materials; bleach soaking can corrode components and is not recommended
for cuffs.
7. Which statement about gloves is correct?
A. Gloves eliminate the need for hand hygiene
B. The same gloves can be used for multiple clients
C. Gloves are required for every activity
D. Gloves should be changed between clients and when contaminated during care
Answer: D
Rationale: Gloves provide a barrier against exposure to potentially infectious materials,
but they do not replace hand hygiene. Gloves must be changed appropriately to
prevent cross-contamination between clients and whenever they become contaminated
during care.
Patient Safety & Emergency Procedures
8. A client complains of intense chest pain that goes down the arm and is
sweating profusely. What should the HHA do?
A. Call for emergency help immediately
B. Massage the chest and arm
C. Assist the client back to bed
D. Call the agency office and wait for instructions
Answer: A
Rationale: Chest pain radiating to the arm with profuse sweating is a classic sign of a
heart attack (myocardial infarction). The HHA must activate emergency medical
services (911) immediately. Massaging, resting, or delaying for agency instructions
could waste critical time.
, 9. A patient with COPD reports increased shortness of breath and use of
accessory muscles. What is the HHA’s priority action?
A. Administer prescribed rescue inhaler
B. Place the patient in a supine position
C. Encourage pursed-lip breathing and notify the nurse
D. Increase oxygen flow rate to 4 L/min
Answer: C
Rationale: Pursed-lip breathing helps reduce air trapping and dyspnea in COPD. The
HHA should also notify the supervising nurse for further assessment. Administering
inhalers or adjusting oxygen is outside HHA scope; a supine position can worsen
breathing.
10. A client in your care has just received news of a death in the family. What is
the best way to assist them with the grieving process?
A. Remind the client that death is inevitable
B. Suggest that the client get their mind off of things by thinking of something
pleasant
C. Tell the client about an experience you had with death and what helped you cope
D. Spend some time with the client, particularly offering support if they wish to talk
about it
Answer: D
Rationale: The most supportive approach is to be present and allow the client to
express feelings if they choose. Dismissing the loss, minimizing it, or making the
conversation about the aide’s own experience does not provide client-centered
emotional support.
Personal Care & Activities of Daily Living
11. Which of the following is an example of an activity of daily living (ADL)?
A. Managing a healthcare agency
B. Scheduling medical appointments for other clients
C. Bathing
D. Diagnosing an illness
Answer: C
Rationale: ADLs are basic self-care activities such as bathing, dressing, toileting, eating,
grooming, and transferring. HHAs commonly assist clients with these activities
according to the care plan.
