Nursing Fundamentals: Patient Positioning, Safety, and Infection Control

Vocabulary flashcards covering core concepts of patient positioning, room safety (SWIPES), standard and transmission-based precautions, stages of infection, types of immunity, diagnostic testing, and multidrug-resistant organisms (MDROs) from Chapter 1 to Chapter 10.

High Fowler's Position

A bed position where the head of the bed is elevated to approximately $90^\circ$; frequently used for patients experiencing shortness of breath.

Trendelenburg Position

A bed position where the bed is flat but tilted head-down; used to allow gravity to assist when boosting heavy patients up in bed.

Reverse Trendelenburg Position

A bed position where the bed frame is flat but tilted with the head elevated higher than the feet.

Supine Position

A postural position where the patient lies completely flat on their back facing upward.

Prone Position

A postural position where the patient lies flat on their belly facing downward.

Dorsal Recumbent Position

A postural position where the patient lies on their back with knees bent; provides visual access for procedures like urinary catheter insertion.

Sims' Position (Semi-Prone)

A posture where the patient lies on their side (commonly left side) with the top knee flexed; optimal for administering suppositories, enemas, or rectal exams.

Orthopnea Position (Tripod Position)

A sitting position assumed by short-of-breath patients (e.g., COPD) who lean forward with arms or elbows supported on a surface to facilitate breathing.

Lithotomy Position

A positioning posture used for gynecologic, pelvic, cervical (pap smear), and male rectal trauma exams with the pelvis accessible and legs supported.

SWIPES

A memory acronym for essential patient interaction steps: Supplies, Wash hands, Introduce & Identify, Privacy, Explain & Educate, Scan for safety.

Line Reconciliation

The systematic process of checking every medical tube and IV line to verify where it goes, how it is labeled, and that it is unkinked and functioning safely.

Four Bed Rails

Raising all four side rails on a patient's bed, which is legally defined as a physical restraint unless explicitly ordered and approved.

Standard Precautions

Universal infection control measures applied to all patients at all times, including hand hygiene, proper PPE selection, sharp safety, and respiratory etiquette.

Contact Precautions

Transmission-based precautions required for direct/indirect contact pathogens (e.g., lice, MRSA); requires mandatory glove use and gowns as needed.

Contact Enteric Precautions

Contact precautions mandatory for spore-forming organisms (e.g., C. diff); requires handwashing using soap and water rather than alcohol sanitizer.

Droplet Precautions

Transmission-based precautions required for pathogens carried in large respiratory drops ($3\text{ to }6\,\text{feet}$); requires a standard surgical mask.

Airborne Precautions

Transmission-based precautions required for small respiratory pathogens ($< 5\,\mu\text{m}$) suspended in air; requires an N95 respirator and negative-pressure isolation.

Maceration

The softening, whitening, and breakdown of skin caused by prolonged exposure to excess moisture; prevented by keeping skin dry and avoiding lotion between toes.

Incentive Spirometer

A pulmonary exercise device measuring patient inspiration (inhalation) to expand lung volume, maximize alveolar expansion, and prevent atelectasis or pneumonia.

Bacteremia

The clinical presence of bacteria within the patient's bloodstream.

Septicemia

A systemic infection resulting from pathogens actively multiplying in the blood, leading to severe clinical manifestations.

Exogenous Infection

A healthcare-acquired infection caused by an infectious agent originating outside the patient's body from contact with external sources or staff.

Endogenous Infection

A healthcare-acquired infection caused by overgrowth of the patient's own resident microflora, often following broad-spectrum antibiotic treatment.

Latent Infection

An infection where the pathogen remains dormant inside host cells without causing active symptoms until reactivated later (e.g., shingles, herpes simplex).

CAUTI

Catheter-Associated Urinary Tract Infection; recognized as the most common hospital-acquired infection.

Prodromal Stage

The early interval of an infection characterized by non-specific, vague onset symptoms before full characteristic disease manifestations appear.

Convalescence

The final recovery period of an infection where the pathogen load decreases and normal health returns, though immunity and stamina remain temporarily weakened.

Active Immunity

Immune protection formed when the host's own body produces antibodies in response to an antigen, either naturally (prior infection) or artificially (vaccination).

Passive Immunity

Temporary immune protection gained by receiving pre-formed antibodies from another source, naturally (placental/breast milk transfer) or artificially (IVIG).

Culture and Sensitivity (C&S)

A laboratory test identifying the specific infectious microorganism (culture) and its antimicrobial susceptibilities (sensitivity); must be drawn before initiating antibiotics.

MRSA

Methicillin-Resistant Staphylococcus Aureus; a resistant bacterial pathogen commonly presenting as swollen skin lesions or wound infections, managed with contact precautions and specific antimicrobials like clindamycin.

Clostridium difficile (C. diff)

A spore-forming bacterial infection of the colon causing severe, foul-smelling diarrhea after normal flora is destroyed by antibiotics; requires contact enteric precautions, vancomycin or flagyl, and soap-and-water handwashing.

VRE

Vancomycin-Resistant Enterococci; a drug-resistant bacterial pathogen commonly responsible for severe, persistent urinary tract infections.

Fecal Microbiota Transplantation (FMT)

A medical procedure transferring healthy donor stool into a patient's GI tract to restore normal colon microflora in severe or recurrent C. diff cases.

OPIM

Other Potentially Infectious Materials; OSHA term for non-intact biological fluids and tissues (such as semen, vaginal secretions, amniotic fluid, and unfixed tissues) requiring protective barriers.
