FINAL EXAM!!! Flashcards
Aseptic
Free from infection
Surgical Asepsis
Practices that keep objects and areas sterile or free from microorganisms
Transient Flora
Microorganisms that reside on the superficial skin layers and are picked up in the course of daily activities
Often pathogenic but can be removed easily from the skin by sanitizing the hands
Malaise
A vague sense of discomfort, weakness, and fatigue that often marks the onset of a disease and continues through the coarse of illness
Bradycardia
An abnormally slow heart rate (less than 60 bpm)
Pulse Pressure
The difference between the systolic and diastolic pressures
External Respiration
Exchange of gases between the lungs and the blood
Apnea
The temporary cessation of breathing
Hypoxia
Reduction in the oxygen supply to the tissues of the body
Prognosis
The probable course and outcome of a patient’s condition and the patient’s prospects for recovery
Risk Factor
Anything that increases an individual’s chance of developing a disease
(Some can be avoided and some can’t)
Hyperopia
Farsightedness
Presbyopia
A decrease in the elasticity of the lens that occurs with aging, resulting in a decreased ability to focus on close objects
Pathogen
Disease producing microorganism
Nonpathogen
A microorganism that does not normally produce disease
Opportunistic Infection
An infection that results from a defective immune system that cannot defend the body from pathogens normally found in the environment
Febrile
Pertaining to fever
Tachypnea
An abnormal increase in the respiratory rate of or more than 20 breaths per min
Bounding Pulse
A pulse with an increased volume that feels very strong and full
Orthopnea
The condition in which breathing is easier when an individual is in a sitting or standing position
Cyanosis
A bluish discoloration of the skin and mucous membranes
Systole
The phase in the cardiac cycle in which the ventricles contract, sending blood out of the heart and into the aorta and pulmonary aorta; opposite of diastole
Chronic
Existing over a long period of time
Myopia
Nearsightedness
Edema
The retention of fluid in the tissues, resulting in swelling
Astigmatism
A refractive error that causes distorted and blurred vision for both near and far objects due to a cornea that is oval shaped
Normal Flora
Harmless, nonpathogenic microorganisms that normally reside in many parts of the body but do not cause disease
Medical Asepsis
Practices that are employed to inhibit the growth and hinder the transmission of pathogenic microorganisms to prevent the spread of infection
Sterilization
The process of destroying all forms of microbial life, including bacterial spores
Detergent
An agent that cleanses by emulsifying dirt and oil
Afebrile
without fever; normal body temperature
Tachycardia
An abnormally fast heart rate; more than 100 bpm
Internal Respiration
Exchange of gases between the blood and tissue cells
Dyspnea
Shortness of Breath or Difficulty breathing
Hypoxemia
A decrease in the oxygen saturation of the blood. Hypoxemia may lead to hypoxia.
Diastole
The phase in the cardiac cycle in which the heart relaxes between contractions; opposite of systole
Erythema
Reddening of the skin caused by dilation of superficial blood vessels in the skin
Crepitus
A grating sensation caused by fractured bone fragments rubbing against each other
Right Eye Abbreviation
