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 caring for a patient who has been immobile for several days. Which of the
following findings should the nurse identify as a complication of immobility?
A. Increased muscle mass
B. Increased cardiac output
C. Improved respiratory gas exchange
D. Decreased range of motion
Correct Answer: D
Explanation: Immobility leads to several physiological changes including contractures and
decreased range of motion due to muscle disuse. Inactivity causes the muscle fibers to
shorten and joint capsules to become stiff. The nurse must implement passive or active
range of motion exercises to prevent these musculoskeletal complications.
2. When performing a sterile procedure such as urinary catheterization, which action by the
nurse would break the sterile field?
A. Opening the sterile pack away from the body
B. Touching only the outer 1-inch border of the sterile drape
C. Keeping sterile gloved hands above the waist
,D. Reaching over the sterile field to pick up a component
Correct Answer: D
Explanation: Reaching over a sterile field is a breach of sterile technique because
microorganisms can fall from the nurse’s non-sterile clothing or skin onto the field. To
maintain sterility, the nurse should always move around the perimeter of the field rather
than across it. A sterile object remains sterile only when touched by another sterile object.
3. A nurse is assessing a patient’s wound and notes the presence of thick, yellow drainage.
How should the nurse document this type of exudate?
A. Serous
B. Purulent
C. Serosanguineous
D. Sanguineous
Correct Answer: B
Explanation: Purulent drainage is thick and often indicates an infection; it can be yellow,
green, or brown in color. Serous drainage is clear and watery, while sanguineous is bright
red and indicates active bleeding. Documentation of wound drainage is a critical nursing
responsibility to track the healing process and detect early signs of infection.
4. The nurse is preparing to administer a cleansing enema to a patient. In which position
should the nurse place the patient to facilitate the flow of fluid into the colon?
A. Right lateral position
, B. Sims’ position
C. High-Fowler’s position
D. Lithotomy position
Correct Answer: B
Explanation: The Sims’ position (left side-lying with the right knee flexed) allows the
enema solution to flow by gravity into the sigmoid colon and rectum. This anatomical
positioning is standard for rectal procedures and medication administration. Placing the
patient in this position also minimizes discomfort and the risk of immediate expulsion.
5. A patient with a stage 3 pressure injury is being treated. Which of the following
characteristics defines a stage 3 pressure injury?
A. Non-blanchable erythema of intact skin
B. Full-thickness skin loss with exposed bone or tendon
C. Partial-thickness skin loss with exposed dermis
D. Full-thickness skin loss involving damage to subcutaneous tissue
Correct Answer: D
Explanation: A stage 3 pressure injury is characterized by full-thickness loss of skin in
which adipose tissue is visible in the ulcer. Bone, tendon, and muscle are not yet exposed,
which would distinguish it from a stage 4 injury. The nurse must monitor for slough or
eschar which may be present but does not obscure the depth of tissue loss.
