- Chain of infection
- Related: Standard precautions, Healthcare-associated 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.
- Healthcare-associated infection

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.
- 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.

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.
- Intradermal injection
- Related: Subcutaneous injection, Intramuscular 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.
- Venipuncture
- Related: Order of draw, Capillary puncture
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.
- Order of draw
- Related: Venipuncture, Hemolysis
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.
- Capillary puncture
- Related: Venipuncture
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.
- Hemolysis
- Related: Venipuncture, Order of draw
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.
