CPCT Certification Study Guide Review

These flashcards cover key terms and definitions related to the Certified Patient Care Technician (CPCT) certification, focusing on EKG interpretation, infection control, patient care, and fundamental medical concepts.

Electrocardiogram (EKG)

A graphic representation of changes in electrical energy of the heart over time.

Electrocardiography

The process of recording the electrical activity of the heart using an EKG machine.

Einthoven’s Triangle

An imaginary equilateral triangle formed by the limb leads used to measure the heart’s electrical activity.

P Wave

Represents atrial depolarization in the EKG.

QRS Complex

Represents ventricular depolarization in the EKG and is characterized by a wide and bizarre shape in cases of ventricular dysfunction.

J Point

The point where ventricular depolarization ends and repolarization begins on the EKG.

ST Segment

Represents the early phase of ventricular repolarization on the EKG.

PR Interval

The time it takes for electrical impulses to travel from the SA node through the AV node, measured from the beginning of the P wave to the start of the Q wave.

Gain (Amplitude)

A standard measure in EKG of 10 mm per 1 mV to ensure accurate recording of electrical activity.

Blood Cultures

Laboratory tests used to identify the presence of bacteria or micro-organisms in a blood sample.

Personal Protective Equipment (PPE)

Protective clothing and equipment designed to protect a worker from exposure to biological hazards.

Standard Precautions

A set of guidelines designed to prevent the transmission of infectious agents in healthcare settings.

Isolation Precautions

Additional precautions taken to prevent the spread of infections that are more virulent or transmitted easily.

Surgical Asepsis

The complete removal of micro-organisms and their spores from the surface of an object, used in invasive procedures.

Medical Asepsis

Techniques that reduce the number and transfer of pathogens, known as clean technique.

Vital Signs

Key indicators of homeostasis including temperature, heart rate, respiratory rate, and blood pressure.

Ambulation

The act of walking or moving about, important for patient mobility and health.

Postmortem Care

Care provided after a patient's death, ensuring respect and dignity for the deceased.

Wound Infection Indicators

Signs such as redness, swelling, warmth, and foul odor that suggest an infection in a wound.

Contracture

Abnormal shortening of muscle or tendons, leading to limited movement around a joint.

First Aid and CPR

Basic life support techniques, including chest compressions and rescue breaths, to provide care in emergencies.

Kübler-Ross Stages of Grief

A model outlining the stages faced by individuals dealing with loss: denial, anger, bargaining, depression, and acceptance.
