MOBILITY ATI ACTUAL 25 QUESTION AND LATEST
ANSWER 2026.
1. A nurse is caring for a client who is at risk for developing atelectasis.
Which of the following actions should the nurse take?
Correct Answer: Remind the client to use incentive spirometer
Expert Rationale: Atelectasis is the collapse of alveoli, which can occur when
patients are immobile, postoperative, or have shallow breathing due to pain. The
incentive spirometer encourages deep breathing and sustained maximal
inspiration, which helps to expand the lungs, prevent alveolar collapse, and
mobilize secretions. The use of an incentive spirometer is a standard prophylactic
measure for preventing atelectasis in at-risk patients. The client should be
instructed to use the incentive spirometer 10 times every hour while awake,
performing slow, deep breaths to achieve maximal lung expansion. Other
interventions to prevent atelectasis include early mobilization, coughing and deep
breathing exercises, and adequate pain management to facilitate deep breathing.
The incentive spirometer is a simple, noninvasive, and highly effective tool that
empowers the patient to participate actively in their own pulmonary hygiene. The
nurse should demonstrate proper technique and monitor the client's use to
ensure effectiveness.
2. A nurse is preparing a poster presentation about the musculoskeletal
system. The nurse should include that which of the following is responsible
for body posture?
Correct Answer: Muscles
,Expert Rationale: Muscles are the primary structures responsible for body
posture. Skeletal muscles maintain posture through sustained, low-level
contractions known as muscle tone. These contractions counteract the force of
gravity and maintain the body's position against external forces. While bones
provide the structural framework and joints allow for movement, it is the muscles
that actively maintain posture and enable the body to remain upright. Proper
posture requires balanced muscle tone, and postural muscles, particularly those of
the back, abdomen, and legs, work continuously to maintain alignment. When
muscle tone is lost due to paralysis, prolonged immobility, or neuromuscular
disorders, posture becomes compromised, and contractures may develop.
Ligaments and tendons also contribute to joint stability, but they are passive
structures that do not actively maintain posture. The nurse should include in the
teaching that skeletal muscles are essential for both movement and postural
maintenance, and that immobility can lead to muscle atrophy and postural
abnormalities.
3. A nurse is teaching a client who has an unsteady gait about how to use a
walker. Which of the following instructions should the nurse include?
Correct Answer: The top of the walker should be at the level of your wrist
Expert Rationale: The proper fit of a walker is essential for safety and
effectiveness. When the client stands upright with arms relaxed at the sides, the
top of the walker handles should be at the level of the client's wrist crease. This
allows the client to walk with approximately 15-30 degrees of elbow flexion,
which provides optimal mechanical advantage, reduces strain on the shoulders
and wrists, and promotes a more natural gait pattern. A walker that is too high or
too low can cause the client to lean forward or backward, increasing the risk of
, falls and contributing to fatigue and back pain. The nurse should also instruct the
client to place the walker approximately one step ahead of the body, to keep the
walker close to the body when walking, and to advance the affected extremity
first when using a standard walker. When sitting down, the client should back up
until the chair is felt, reach back with one hand, and then slowly lower into the
chair. The client should be observed using the walker to ensure proper technique
and safety before ambulating independently.
4. A nurse is caring for a client who has pneumonia. In which of the
following positions should the nurse place the client to promote postural
drainage?
Correct Answer: Prone
Expert Rationale: Postural drainage uses gravity to assist in mobilizing and
removing secretions from the lungs. The position used depends on which lung
segments need to be drained. For the posterior segments of the lungs,
particularly the lower lobes, the prone position (lying on the abdomen) is often
used to facilitate drainage. In the prone position, gravity assists in the movement
of secretions from the dependent lung segments toward the larger airways where
they can be coughed out. The nurse should place the client in the prone position
with the head lower than the chest to promote drainage from the lower lobes
(Trendelenburg position). Postural drainage is often combined with percussion
and vibration (chest physiotherapy) to further loosen secretions. Before
performing postural drainage, the nurse should auscultate the lungs to identify
areas of congestion. The client should be positioned for 10-15 minutes in each
position. Postural drainage is contraindicated in clients with increased intracranial
pressure, recent spinal surgery, or unstable cardiovascular status. The client
