NSG 122 Final Exam V2 | NSG 122 Nursing
Fundamental Concepts | Herzing | 2026 Q&A with
Rationale (Herzing NSG122 Final Exam 2026)
1. A nurse is preparing to assess a client’s blood pressure. Which action by the nurse would
result in a falsely high blood pressure reading?
A. Using a cuff that is too wide for the client’s arm
B. Deflating the cuff at a rate of 2 to 3 mmHg per second
C. Supporting the client’s arm at the level of the heart
D. Using a cuff that is too narrow for the client’s arm
Correct Answer: D
Explanation: Using a blood pressure cuff that is too narrow or too small for the client’s
arm size will result in a falsely high reading. This occurs because the small bladder cannot
evenly distribute pressure, requiring more inflation to occlude the artery. Conversely, a cuff
that is too wide would result in a falsely low reading.
2. A nurse is caring for a client with a history of falls. Which of the following is the priority
nursing intervention to ensure client safety?
A. Keep all four side rails in the upright position
B. Administer a mild sedative to keep the client in bed
C. Place the call bell within the client’s reach
,D. Encourage the client to use the bathroom independently
Correct Answer: C
Explanation: Ensuring the call bell is within reach is a fundamental safety intervention
that allows the client to request assistance before attempting to get up alone. Keeping four
side rails up is often considered a restraint and requires a specific order. The priority is
always to provide the means for communication and assistance to prevent unassisted
ambulation.
3. When performing hand hygiene with an alcohol-based hand rub, the nurse should continue
rubbing the hands together until:
A. At least 10 seconds have passed
B. The alcohol rub has completely dried
C. The hands are visibly clean
D. The nurse reaches the sink to rinse
Correct Answer: B
Explanation: For alcohol-based hand rubs to be effective, the nurse must rub all surfaces
of the hands until the solution has completely evaporated and the skin is dry. This process
typically takes about 20 to 30 seconds depending on the volume used. Drying ensures that
the antimicrobial properties of the alcohol have had sufficient contact time with the skin.
, 4. A nurse is preparing to administer an intramuscular (IM) injection to an adult client. Which
site is preferred for its lack of large blood vessels and nerves?
A. Ventrogluteal
B. Dorsogluteal
C. Vastus lateralis
D. Deltoid
Correct Answer: A
Explanation: The ventrogluteal site is the preferred site for IM injections in adults and
children over 7 months of age. It is situated away from major blood vessels and nerves,
such as the sciatic nerve, which reduces the risk of injury. Research consistently supports
this site as the safest option for deep muscle injections.
5. Which of the following describes the ‘Evaluation’ phase of the nursing process?
A. Collecting subjective and objective data from the client
B. Determining if the client’s goals and outcomes were met
C. Setting measurable goals with the client
D. Carrying out nursing interventions to meet client needs
Correct Answer: B
Explanation: Evaluation is the final step of the nursing process where the nurse compares
the client’s current status with the desired outcomes. This step determines if the nursing
