A Level Health & Social Care/Schemes of work/Version 1.0
Unit Title HSC10: Diagnosis, Treatment and Preventative Strategies (Optional)
This unit aims to introduce a variety of diagnostic techniques and the principles and key points of practice of a range of common medical
treatments. This unit also looks into ways in which common diseases and disorders can be prevented.
Method of assessment – written examination

Diagnosing
disease
Learning objectives / understanding
Key terms /
definitions
Understand that diagnosis is the identification
by a health care professional of a disease
process that is causing a person’s ill health or
other complaint, and that this is essential in
order to begin appropriate treatment. This will
include identifying both the disease process
and the agent responsible. There are several
steps to the process and these may include:


Diagnostic
techniques to
include
screening
tests
Screening tests
Screening
Understand that early detection of a disease or
disorder, often in presymptomatic stages, will
allow treatment to be more effective. Screening
tests may be suitable for the whole population
or for specific groups of people at special risk,
e.g. people over a certain age, people with a
family history of a particular disorder or people
employed in hazardous occupations.
Presymptomatic
Antenatal
Genetic
Down’s
syndrome
Know who the client group is, how each test is
performed, what is being looked for and how
positive or negative results are recognised. The
tests to be covered are:
Cystic fibrosis
Antenatal screening tests:
Sickle cell
anaemia


Amniocentesis for genetic disorder
Down’s syndrome, spina bifida and
sickle cell anaemia
Chorionic villus sampling for genetic
disorder cystic fibrosis and muscular
dystrophy and sickle cell anaemia
Blood tests for anaemia and blood
groupings to include the rhesus factor.

different client groups and their importance and
success rates in the UK.

tests may be needed to make a diagnosis.

Strategies to
Prevent
Disease:
Immunisation
Understand how different dangerous diseases
can be avoided through immunisation, i.e. the
artificial creation of immunity against infection.
The difference between active and passive
immunity must also be understood. Understand
how immunisation works by attacking invading
micro-organisms through the use of antibodies.
Immunisation

Active immunity

Passive
immunity

Antibody
Understand that infants and children are
immunised against:




Diphtheria
Pertussis (whooping cough)
Tetanus
Measles, mumps, rubella (triple MMR
vaccine).
The following vaccinations are recommended
for people of any age who travel to different
countries which have specific health risks.
Common examples include protection against:





Cholera
Hepatitis A
Hepatitis B
Typhoid
Rabies
For each of the vaccinations know about the:


Disease which the vaccine protects
against
Causes of the disease, i.e. an organism,
e.g. bacteria or virus and its name

and short term

Symptom
Progression
Side effect
Understand that many illnesses and injuries are
not serious and most clear up without any
treatment being necessary. Self-treatment may
be required in other cases to relieve symptoms
and help the person feel more comfortable.
Self-treatment includes bed rest, drinking plenty
of fluids and/or taking over-the-counter
medications for common diseases such as
coughs and colds. Understand, however, that
where symptoms persist, a health care
professional should be consulted and this may
lead to treatments of different kinds.
Self- treatment
Understand the principles of home nursing for
sick people and of hospital nursing including
intensive care.
Chemical name
Drug treatment
Brand name
This is the use of a chemical substance that
alters the function of one or more body organs
or changes the process of disease. Each drug
normally has three names, i.e. a detailed
descriptive chemical name, a shorter generic
name (official medical name) and a specific
brand name chosen by the manufacturer.

Drugs are either licensed for prescription or
available over-the-counter and may be from
naturally occurring substances or artificially
produced, sometimes by genetic engineering.
surgery
Know that drugs are classified, firstly according
to chemical make-up, secondly to the disorder
treated and thirdly by their specific effects on
the body.
Aseptic
techniques
All new drugs are tested for efficacy and safety.
The different methods of administering drugs,
i.e. by mouth, injection, creams, suppositories
or sprays should be known, and the reasons for
administration in each case. Appreciate that
drugs can produce adverse side-effects and a
drug is only useful if its overall benefit
outweighs any risk and severity of these sideeffects.
Surgical treatment as a minor or major
direct physical intervention
Operative surgery involves incision and the
inspection and removal of diseased tissues or
organs and/or replacement or redirection of
body channels and/or implantation of electronic
or medical devices.
Understand the broad principles of transplant
surgery including the need for aseptic
techniques and general/local anaesthesia. The
broad principles of endoscopic surgery,
microsurgery and laser surgery should also be
understood.

HSC10 Scheme of Work V1
Radiotherapy is the treatment of cancer and
other diseases using ionising radiation to
destroy or slow down abnormal cell growth.
Understand that this is sometimes used on its
own and sometimes in conjunction with surgical
techniques. Radiotherapy can be administered
from a machine outside the body or by
introducing radioactive material into the body.
Understand that the relative benefits of using
this treatment must be weighed against the
side-effects it produces.
Other techniques
Other techniques, including the broad principles
of dialysis and lithotripsy in relation to the
kidney.
3.10.6
Factors
affecting
treatment
Understand that individuals may be affected
differently by a particular treatment and may
wish to make other choices about treatment
and quality of life. Appreciate the
consequences of delayed treatment and
understand that ethical issues are associated
with the treatment of disease and dysfunction,
e.g. where lifestyle choices relating to physical
exercise, diet, alcohol consumption and
smoking may reduce the effectiveness of
treatment.

3.10.7 Assessment
You will be assessed on your knowledge, understanding and skills relating to diagnosis and treatment through a written examination of two
hours.
There will be four compulsory structured questions which will include a mixture of short item and free response items. These will require you to
demonstrate and apply your knowledge, understanding and skills of diagnosis and treatment.
You will also be required to analyse relevant data, including numerical data, relating to diagnosis and treatment and to evaluate the evidence,
make judgements and draw conclusions.
The questions will be drawn from the following four areas of the unit:




diagnosing disease
diagnostic techniques to include screening tests
strategies to prevent disease – immunisation
treating disease
To gain high marks in your written examination you should ensure that:





your answers show a good level of detail, depth relevance and accuracy
you apply knowledge, understanding and skills top the material presented in the questions successfully
data analysis is thorough and produces clear, logical reasoning and judgements;
suggestions and opinions are supported by the data and the material covered in all areas of the unit
conclusions are consistent with the data and level of detail.
