NSG 122 Exam 3 V1 | NSG 122 Nursing
Fundamental Concepts | Herzing | 2026
Q&A with Rationale (Herzing NSG122
Exam 3 2026)
1. A nurse is preparing to administer an intramuscular injection to an adult client. Which of
the following sites is considered the safest and most preferred for this procedure?
A. Dorsogluteal site
B. Ventrogluteal site
C. Vastus lateralis
D. Deltoid muscle
Correct Answer: B
Rationale: The ventrogluteal site is the preferred site for intramuscular injections in adults
because it is situated away from major blood vessels and nerves. This site provides a large
muscle mass that is capable of absorbing significant medication volumes safely. Using the
dorsogluteal site is no longer recommended due to the high risk of hitting the sciatic nerve.
2. When performing a sterile dressing change, the nurse drops a sterile gauze pad onto the
edge of the sterile field. Which action should the nurse take next?
A. Consider the gauze contaminated and discard it.
B. Pick up the gauze with sterile forceps and use it.
,C. Spray the gauze with normal saline to re-sterilize.
D. Ask another nurse to verify if the gauze touched the non-sterile area.
Correct Answer: A
Rationale: A one-inch border around the edge of a sterile field is considered contaminated.
Any item that touches this border or falls outside the field is no longer sterile and must be
discarded immediately. Maintaining strict surgical asepsis is critical to prevent healthcare-
associated infections in surgical wounds.
3. A nurse is caring for a client who is at high risk for falls. Which of the following nursing
interventions is the priority?
A. Place the client’s bed in the lowest position.
B. Keep all four side rails in the up position.
C. Apply soft wrist restraints to prevent the client from getting up.
D. Instruct the client to call for help only if they feel dizzy.
Correct Answer: A
Rationale: Keeping the bed in the lowest position reduces the distance of a potential fall
and is a standard safety measure. Four side rails are often considered a restraint and
require a specific order and clinical justification. Continuous assessment and utilizing call
lights for all transfers are safer alternatives than physical restraints.
, 4. A client is diagnosed with Clostridium difficile (C. diff). Which infection control precaution
must the nurse implement?
A. Droplet precautions with a surgical mask.
B. Airborne precautions with an N95 respirator.
C. Contact precautions with soap and water handwashing.
D. Standard precautions with alcohol-based hand rub.
Correct Answer: C
Rationale: C. diff requires contact precautions because the spores are spread through
direct and indirect contact with contaminated surfaces. Alcohol-based hand sanitizers are
ineffective against C. diff spores, so handwashing with soap and water is mandatory. Gowns
and gloves must be worn when entering the room to prevent cross-contamination.
5. The nurse is assessing a pressure injury and notes full-thickness skin loss with visible
subcutaneous fat, but no bone or muscle is exposed. How should the nurse stage this injury?
A. Stage 1
B. Stage 2
C. Stage 4
D. Stage 3
Correct Answer: D
