INSTANT PDF DOWNLOAD - This is the comprehensive Exam study guide for NR 224 Fundamentals of Nursing at Chamberlain University (Latest 2026/2027 Update), featuring verified exam questions with correct answers and detailed rationales covering Health Promotion, Infection Control, and Mobility/Safety. Health Promotion & Wellness – three levels of prevention (primary prevention aims to prevent disease through vaccines/healthy lifestyle, secondary prevention focuses on early detection via screenings, tertiary prevention manages existing disease to prevent complications) ; internal variables (biologic, psychologic, cognitive) vs external variables (environment, family/cultural beliefs) ; the 7 components of wellness (Environmental, Occupational, Intellectual, Spiritual, Physical, Emotional, Social) . Infection Control – chain of infection (causative agent, reservoir, portal of exit, mode of transmission, portal of entry, susceptible host) ; stages of infection (incubation, prodromal, illness, convalescence) ; standard precautions for all patients, transmission-based precautions (contact, droplet, airborne) ; hand hygiene is most effective infection prevention measure, four moments for hand hygiene (before patient contact, before aseptic procedure, after body fluid exposure, after patient contact) ; medical asepsis (clean technique) vs surgical asepsis (sterile technique) . Mobility, Body Mechanics & Safety – body alignment (neutral spine position reduces stress on muscles/joints), center of gravity (below umbilicus at top of pelvis, should be close to base of support) , proper body mechanics (lift with legs not back, keep objects close to body, avoid twisting) ; fall prevention in hospitals (bed alarm, fall risk bracelet, call light within reach, bed in low position, side rails up) ; Fall prevention in homes (remove throw rugs/loose carpets, install grab bars near toilet/tub, monitor gait/balance, provide assistive devices) . Assistive devices: canes (hold on strong side, measure to greater trochanter with elbow flexed 15°, cane moves with weak leg) ; walkers, crutches (crutches placed 2-3 finger widths below axilla to prevent brachial nerve damage) . Range of motion terminology – abduction (movement away from midline), adduction (movement toward midline), circumduction, flexion, extension, rotation . Benefits of regular exercise on Cardiovascular system (improves pumping action, decreases HR/BP, improves venous return) ; Respiratory system (improves pulmonary circulation and gas exchange, dilates bronchioles, reduces pneumonia risk) ; Musculoskeletal system (increases muscle strength/flexibility, improves bone density) ; Psychosocial benefits (improves self-esteem, provides nonpharmacological anxiety/depression management) . Patient positioning – Fowler's (semi-sitting 45-60°), High-Fowler's (head raised 90°), supine, prone, lateral, Sims, Trendelenburg . INSTANT DIGITAL DOWNLOAD (PDF) immediately upon purchase.

HEALTH PROMOTION, INFECTION, MEDICATIONS, WOUNDS & Questions 1 –
MOBILITY 120+

1. Define health promotion.
A. Treating disease after it occurs.
B. Helping individuals maintain or enhance their present health.
C. Preventing all forms of illness.
D. Only providing immunizations.
CORRECT ANSWER B — Helping individuals maintain or enhance their present health

RATIONALE Health promotion is proactive — it focuses on helping individuals, families, and communities maintain or
improve their current level of wellness. It includes activities such as health education (physical awareness,
stress management, self-responsibility), lifestyle modification, and creating environments that support
health. This differs from illness prevention, which focuses on avoiding specific diseases.

, 2. What are the three levels of preventive care?
A. Acute, subacute, and chronic.
B. Primary, secondary, and tertiary.
C. Individual, family, and community.
D. Assessment, intervention, and evaluation.
CORRECT ANSWER B — Primary, secondary, and tertiary

RATIONALE Primary prevention is true prevention — reducing the incidence of disease (immunizations, health education,
seatbelt use). Secondary prevention focuses on early detection and prompt treatment to prevent disease
spread or complications (screenings — mammogram, colonoscopy, BP checks). Tertiary prevention occurs
when a defect or disability is permanent; it minimizes the long-term effects and maximizes function
(rehabilitation, support groups, cardiac rehab after MI).


3. Which of the following is NOT one of the five steps of the nursing process?
A. Planning.
B. Evaluation.
C. Assessment.
D. Hypothesis testing.
CORRECT ANSWER D — Hypothesis testing

RATIONALE The nursing process consists of five steps: Assessment, Diagnosis (Analysis), Planning, Implementation, and
Evaluation (ADPIE). Hypothesis testing is a component of the scientific method and critical thinking but is not
one of the five formal steps of the nursing process. The nursing process is the systematic framework guiding
all nursing care.


4. Which is the most significant and commonly found infection-causing agent in healthcare institutions?
A. Bacteria.
B. Fungi.
C. Viruses.
D. Mold.
CORRECT ANSWER A — Bacteria

RATIONALE Bacteria are the most prevalent infectious agents in healthcare settings. They cause a wide range of HAIs
including: Staphylococcus aureus (surgical site infections, bacteremia), Clostridium difficile (antibiotic-
associated colitis), Escherichia coli (UTIs), and Pseudomonas aeruginosa (ventilator-associated pneumonia).
Bacteria are classified by shape (cocci, bacilli, spirilla), Gram stain (positive/negative), and oxygen
requirements (aerobic/anaerobic).


5. Standard precautions should be used when caring for a noninfectious, postoperative patient who is vomiting
blood.
A. True.
B. False.
CORRECT ANSWER A — True

RATIONALE Standard precautions (Tier 1) are applied to ALL patients regardless of diagnosis or presumed infection status.
They apply to contact with blood, all body fluids, non-intact skin, and mucous membranes. Vomiting blood
(hematemesis) involves blood exposure, which requires standard precautions including gloves, and
potentially gown/face protection if splashing is anticipated. A patient does not need to have a known
infection for standard precautions to apply.
