EXAMINATION STUDY GUIDE
▸ This document contains verified Q&A for NR 224 Fundamentals of Nursing Exam 2 (2026/2027 Update).
▸ Covers mobility systems, immobility complications (respiratory, cardiovascular, musculoskeletal, integumentary,
urinary, metabolic, GI), patient positioning, oxygen delivery devices, hypoxia/hypoxemia differentiation, urinary
elimination, urinary terms, I&O calculations, and catheter care.
▸ Each answer includes clinical rationale based on evidence-based practice and Chamberlain University nursing
curriculum standards.
▸ Use this guide to prepare for the exam and for clinical application in foundational nursing practice.
SECTION I — MOBILITY SYSTEMS & IMMOBILITY COMPLICATIONS Q1–Q17
1. What systems are involved in mobility?
CORRECT ANSWER: Musculoskeletal and Neurological systems.
RATIONALE: The musculoskeletal system provides structure and movement. The neurological system controls and
coordinates movement.
2. What factors impact immobility?
CORRECT ANSWER: Congenital defects, bone/joint/muscle disorders, inflammatory joint disease, central
nervous system disorder, musculoskeletal trauma.
RATIONALE: Any condition affecting bones, joints, muscles, or nerves can limit mobility. Immobility leads to
multisystem complications.
, 3. What are possible respiratory complications of immobility?
CORRECT ANSWER: Atelectasis, mucous/sputum build-up, pneumonia, hypoxia.
RATIONALE: Atelectasis is collapse of alveoli from shallow breathing. Secretions pool in dependent lung areas,
increasing infection risk.
4. What assessments are performed for respiratory complications of immobility?
CORRECT ANSWER: Perform respiratory assessment every 2 hours or more frequent. Inspect chest wall
movement and cough. Auscultate lung sounds (diminished breath sounds). Monitor vital signs.
RATIONALE: Early detection of respiratory changes prevents serious complications. Diminished breath sounds
indicate inadequate ventilation.
5. What are implementations to prevent respiratory complications of immobility?
CORRECT ANSWER: Deep breathing and coughing, incentive spirometer, positioning changes, oxygen
therapy, chest physiotherapy (Chest PT), suctioning, hydration (oral or IV fluids).
RATIONALE: Incentive spirometry encourages deep breathing to prevent atelectasis. Hydration thins secretions for
easier expectoration.
6. What are possible cardiovascular complications of immobility?
CORRECT ANSWER: Orthostatic hypotension, increased cardiac workload, venous thromboembolism (VTE) -
blood clot.
RATIONALE: VTE includes deep vein thrombosis (DVT) and pulmonary embolism (PE). Venous stasis from immobility
increases clot risk.
7. What are implementations to prevent cardiovascular complications of immobility?
CORRECT ANSWER: Anti-embolic stockings (TED hose), change position q2hr, anticoagulants (heparin,
Lovenox, etc.), dangle patient when sitting or prior to standing.
RATIONALE: TED hose promote venous return. Dangling prevents orthostatic hypotension.
8. The effects of immobility on the cardiac system include which of the following? (Select all that apply)
CORRECT ANSWER: A, B, E. Thrombus formation, increased cardiac workload, orthostatic hypotension.
RATIONALE: Venous stasis leads to thrombus formation. Decreased venous return increases cardiac workload.
Orthostatic hypotension occurs from vasodilation and decreased fluid volume.
