Medical asepsis

Practices that reduce the number and spread of microorganisms, such as hand hygiene, gloves, and cleaning surfaces. It does not destroy all organisms and is used in routine patient care areas.

Related: Surgical asepsis, Standard precautions
Surgical asepsis

Techniques that keep an area and objects completely free of all microorganisms, including spores. Used for sterile procedures like catheter insertion, dressing changes, and assisting with minor surgery.

Related: Medical asepsis, Sterile field
Standard precautions

Infection-control measures applied to every patient regardless of diagnosis, including hand hygiene, gloves, gowns, masks, and eye protection when contact with blood or body fluids is likely.

Related: Personal protective equipment, Transmission-based precautions
Transmission-based precautions

Extra precautions used in addition to standard precautions for patients with known or suspected contagious infection. Categories are airborne, droplet, and contact, each with specific room, mask, and equipment rules.

Related: Standard precautions, Personal protective equipment
Personal protective equipment

Barrier items worn to protect the wearer from exposure to infectious agents or hazardous materials, including gloves, gowns, masks, respirators, and eye protection. Must be removed in the correct order to avoid contamination.

Related: Standard precautions, Transmission-based precautions
Sterile field

A work area kept free of all microorganisms, created with a sterile drape and sterile supplies. Only sterile items may touch it, and the medical assistant must not reach over it or turn away from it.

Related: Surgical asepsis, Autoclave
Autoclave

Device that sterilizes instruments using pressurized steam at high temperature. Items must be cleaned first, packaged properly, and allowed to dry; indicators confirm that sterilization conditions were met.

Related: Sterile field, Sanitization
Sanitization

The lowest level of decontamination: physically removing debris and reducing microorganism counts on surfaces and equipment, usually with soap, water, and friction. It does not kill all organisms.

Related: Autoclave, Medical asepsis
Chain of infection

Model describing the six steps required for infection to spread: infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. Breaking any link prevents transmission.

Related: Standard precautions, Healthcare-associated infection
Healthcare-associated infection

An infection a patient acquires while receiving care in a health facility that was not present or incubating at admission. Prevention relies on hand hygiene, asepsis, and proper equipment cleaning.

Related: Chain of infection, Medical asepsis
Needlestick injury

Accidental puncture of the skin with a used needle or other sharp. The assistant should wash the site, report immediately, and follow the facility's post-exposure protocol for evaluation and testing.

Related: Sharps container, Bloodborne pathogens
Bloodborne pathogens

Microorganisms present in blood that can cause disease when they enter the body, notably hepatitis B, hepatitis C, and HIV. Occupational exposure is governed by workplace exposure-control plans and vaccination offers.

Related: Needlestick injury, Standard precautions
Sharps container

Puncture-resistant, labeled, leakproof receptacle for used needles, lancets, and broken glass. It is filled only to the marked fill line and closed and replaced by trained staff according to policy.

Related: Needlestick injury
Vital signs

Core measurements of body function: temperature, pulse, respiration, blood pressure, and often oxygen saturation and pain. Values are compared with the patient's baseline and normal ranges and reported when abnormal.

Related: Blood pressure, Pulse oximetry
Blood pressure

Force of blood against artery walls, recorded as systolic pressure over diastolic pressure in millimeters of mercury. Technique requires correct cuff size, patient rest, and arm support at heart level.

Related: Vital signs, Korotkoff sounds
Korotkoff sounds

Sounds heard through the stethoscope over the brachial artery while the blood pressure cuff deflates. The first clear tapping sound marks systolic pressure and the point where sounds disappear marks diastolic.

Related: Blood pressure
Pulse oximetry

Noninvasive measurement of oxygen saturation in arterial blood using a clip or probe on a finger or earlobe. Nail polish, cold hands, and poor circulation can produce inaccurate readings.

Related: Vital signs
Orthostatic hypotension

A drop in blood pressure when a person stands up from lying or sitting, causing dizziness or fainting. The assistant measures pressure and pulse in more than one position to detect it.

Related: Blood pressure, Vital signs
Intramuscular injection

Injection of medication deep into a muscle, commonly the deltoid or ventrogluteal site. Needle length and gauge depend on site, patient size, and medication volume and viscosity.

Related: Subcutaneous injection, Intradermal injection
Subcutaneous injection

Injection of medication into fatty tissue beneath the skin, often the abdomen, thigh, or upper arm. Short needles are used, and sites are rotated to prevent tissue damage.

Related: Intramuscular injection, Intradermal injection
Intradermal injection

Injection of a small volume of medication just under the top layer of skin, usually on the inner forearm, creating a small wheal. Used for allergy and tuberculosis skin testing.

Related: Subcutaneous injection, Intramuscular injection
Venipuncture

Puncture of a vein to obtain blood, typically with a needle and collection tube system or butterfly set. Requires correct identification, site selection, tourniquet timing, and order of draw.

Related: Order of draw, Capillary puncture
Order of draw

Standardized sequence for filling blood collection tubes during venipuncture so that additive carryover between tubes does not alter test results. Tubes are filled in the order specified by the collection system.

Related: Venipuncture, Hemolysis
Capillary puncture

Collection of a small blood sample by pricking the skin, usually a fingertip or infant heel. The first drop is wiped away, and the site is warmed to improve blood flow.

Related: Venipuncture
Hemolysis

Breakdown of red blood cells that releases hemoglobin into the sample, giving plasma a red tint. It can be caused by rough handling, small needles, or shaking tubes and may make results unreliable.

Related: Venipuncture, Order of draw
Electrocardiogram

Recording of the heart's electrical activity through electrodes placed on the chest and limbs. It shows rate, rhythm, and conduction patterns, and the assistant must ensure clean, dry skin and correct lead placement.

Related: Artifact
Artifact

Interference on a tracing or reading that does not come from the patient's own physiology, such as movement, muscle tension, or a loose electrode. It must be corrected before results are interpreted.

Related: Electrocardiogram
Medical record

Legal, confidential document of a patient's care, including history, findings, orders, and treatment. Entries must be accurate, dated, timed, signed, and made promptly; errors are corrected without obscuring the original.

Related: Protected health information, Informed consent
Protected health information

Individually identifiable health information held or transmitted by a covered entity. Access is limited to those with a need to know, and disclosures require patient authorization or a permitted exception.
