SECTION 1: ROLE OF THE NURSING ASSISTANT (Questions 1-8)
**Question 1**
A nursing assistant's role in the care of a resident with Alzheimer's disease includes:
A) Diagnosing the stage of the disease
B) Prescribing medications for behavioral symptoms
C) Providing a calm, structured environment and assisting with activities of daily living
D) Determining when the resident needs to be hospitalized
**Answer:** C) Providing a calm, structured environment and assisting with activities of daily
living
**Rationale:** The nursing assistant (CNA) works under the supervision of licensed nurses and
provides hands-on care, including ADLs, maintaining a safe environment, and reporting changes
to the nurse. Diagnosis, medication prescription, and decisions about hospitalization are outside
the CNA's scope of practice and must be performed by licensed professionals (physicians, NPs,
RNs).

**Question 2**
Which of the following tasks is within the scope of practice for a certified nursing assistant?
A) Inserting a urinary catheter
B) Administering medications
,C) Measuring and recording vital signs
D) Changing a sterile dressing
**Answer:** C) Measuring and recording vital signs
**Rationale:** Measuring and recording vital signs (temperature, pulse, respiration, blood
pressure, pain level) is a standard task within the CNA scope of practice after proper training.
Catheter insertion, medication administration, and sterile dressing changes require licensed
nursing supervision and are not permitted for CNAs in most states.

**Question 3**
A nursing assistant notices that a resident's oxygen tubing has become disconnected. The CNA
should:
A) Reconnect the tubing immediately
B) Ignore it and continue with other tasks
C) Call the nurse and wait for instructions
D) Remove the oxygen completely
**Answer:** A) Reconnect the tubing immediately
**Rationale:** Oxygen tubing disconnection is a safety issue that requires immediate correction.
The CNA should reconnect the tubing to ensure the resident continues to receive oxygen. After
reconnecting, the CNA should report the incident to the nurse. Waiting to call the nurse delays
necessary oxygen delivery and could harm the resident.

**Question 4**
A nursing assistant is caring for a resident who is confused and attempts to get out of bed
frequently. The best action is to:
, A) Apply wrist restraints to prevent falls
B) Ask the nurse for a sedative medication
C) Check the resident frequently and offer toileting, fluids, and reassurance
D) Ignore the behavior; it is normal for confused residents
**Answer:** C) Check the resident frequently and offer toileting, fluids, and reassurance
**Rationale:** Restraints should be avoided unless absolutely necessary and ordered by a
physician. The best approach is to identify the cause of restlessness (pain, need to toilet, hunger,
thirst) and address it. Frequent checks, offering toileting, and providing reassurance can reduce
restlessness without restraints. Restraints can cause injury and are a last resort.

**Question 5**
A nursing assistant is asked to perform a task that she has not been trained to do. The CNA
should:
A) Perform the task anyway to be helpful
B) Refuse to perform the task and explain that she has not been trained
C) Ask another CNA to perform the task
D) Perform the task and hope nothing goes wrong
**Answer:** B) Refuse to perform the task and explain that she has not been trained
**Rationale:** CNAs must only perform tasks for which they have received proper training and
that are within their scope of practice. Performing untrained tasks could harm the resident and
could result in disciplinary action or loss of certification. The CNA should politely refuse and
notify the nurse.
