A

FINGERS & HANDS

30
Q

Activities designed to protect patients and other members of the public from actual or potential health threats and their harmful consequences.

A

DISEASE PREVENTION

31
Q

Four levels of disease prevention

A

Primordial
Primary
Secondary
Tertiary

32
Q

Prevention of emergence or development of risk factor in countries or population groups in which they have not yet appeared.

A

PRIMORDIAL PREVENTION

33
Q

Action taken prior to onset of disease, which removes the possibility that a disease will ever occur.

A

PRIMARY PREVENTION

34
Q

Action which halts the progress of the disease at its incipient stage and prevents complication.

A

SECONDARY PREVENTION

35
Q

All measures available to reduce or limit impairments and disabilities and minimize suffering caused by existing departures from good health and to promote the patients adjustment to irremediable conditions.

A

TERTIARY PREVENTION

36
Q

INTERVENTION: Individual and mass education
EXAMPLES: national progammes and policies on food and nutrition, against smoking and drugs, and to promote regular physical exercise.

A

PRIMORDIAL PREVENTION

37
Q

INTERVENTION: Prepathogenesis stage of disease.
MODES OF INTERVENTION: health promotion and specific protection

A

PRIMARY PREVENTION

38
Q

INTERVENTION: Early pathogenesis stage MODES OF INTERVENTION: Early diagnosis and adequate/ prompt treatment.

A

SECONDARY PREVENTION

39
Q

INTERVENTION: Late pathogenesis
MODES OF INTERVENTION: Disability limitations and rehabilitation

A

TERTIARY PREVENTION

40
Q

also known as blood and body fluid exposure, is a common route of transmission for many infectious diseases.

A

41
Q

EXAMPLES OF BODY SUBSTANCES OR FLUIDS

A

Fluids that surround our internal organs

42
Q

Some of the diseases transmitted through body substances include:

A

-HIV/AIDS
-Hepatitis B and C
-Meningitis
-Sexually Transmitted Infections (STI)(e.g. syphilis)
-Respiratory Infections
-Other Infectious Diseases

43
Q

an essential practice that protects both patients and healthcare providers from infectious diseases like HIV, hepatitis, and other contagious illnesses. By isolating all body substances (blood, urine, feces, tears, etc.), we significantly reduce the chances of disease transmission.

A

44
Q

refers to the state of being free from disease-causing microorganisms, particularly bacteria, viruses, fungi, and parasites.

A

Asepsis

45
Q

DOES ASEPSIS PLAY A VITAL ROLE IN THE CYCLE OF INFECTION?

A

YES!

46
Q

-a state of being completely free from all living microorganisms
-having a complete absence of viable life that has the potential to reproduce

A

STERILE

47
Q

-the removal of visible dirt, dust, or contaminants from a surface or environment.
-to reduce the overall number of microorganisms or to prevent or reduce the risk of transmission of microorganisms

A

CLEAN

48
Q

encompasses a range of measures aimed at preventing the spread of infections and ensuring the safety of patients, healthcare workers, and visitors. This includes practices such as proper handwashing techniques, gloving techniques, sterile and aseptic techniques. Maintaining cleanliness and sterilization of medical equipment and surfaces, adhering to isolation protocols for patients with infectious diseases, and following established guidelines for the safe handling and disposal of medical waste. These practical precautions are essential for minimizing the risk of healthcare-associated infections and promoting a safe healthcare environment for all.

It is essential for preventing the spread of infections, including viruses and bacteria, particularly in healthcare settings, food preparation, and everyday activities.

A

Handwashing

51
Q

In medicine, “______” refers to the method used by healthcare professionals to properly don sterile gloves to prevent contamination during medical procedures. This technique is crucial for maintaining aseptic conditions and reducing the risk of infection for both the patient and the healthcare provider.

A

gloving technique

52
Q

is used for short invasive procedures. It involves
*hand hygiene
*sterile gloves
*use of clean dedicated area

A

A

STERILE TECHNIQUE

54
Q

a method used in laboratories or clinical setting to prevent the transmission of unwanted organisms.

A

Aseptic Technique

55
Q

Two types of Aseptic technique

A

Medical Asepsis
Surgical Asepsis

56
Q
  • the methods used in a general medical setting to reduce the spread of microbes and eliminate such contaminants.
A

Medical asepsis

57
Q
  • the methods used to eliminate microbes and maintain asepsis during an invasive or surgical procedure
A
