This guide covers the Unit 14 Health and Social Care BTEC Level 3 assignment – Unit 14: Physiological Disorders and their Care in the Pearson BTEC Nationals in Health and Social Care (2016 specification). It explains all four learning aims, what each Pass, Merit and Distinction criterion asks for, how to structure your information pack and treatment plan, and gives model paragraphs and a worked case study based on type 2 diabetes.
Related brief: BTEC International Level 3 Health and Social Care Unit 10 Physiological Disorders and their Care – Assignment Brief — this is the International version of the same topic; the learning aims match Unit 14 closely, so it is useful practice, but always work from the brief your own centre issues.
What the Unit 14 assignment asks you to do
Unit 14 asks you to study physiological disorders – conditions caused by a fault in how a body system works – and how people with them are diagnosed, treated and supported. Most centres set it as two assignments.
- Assignment 1 (learning aims A, B and C): a report or information pack on two different physiological disorders, for example as material for a healthcare course interview or a staff training session. You explain causes, signs and symptoms, compare how each is investigated and diagnosed, and explain the treatment, support, carers and care settings involved.
- Assignment 2 (learning aim D): a treatment plan for one service user with a physiological disorder, using a case study or anonymised person. You assess their care needs, plan treatment and explain how it will improve their health and wellbeing.
Disorders are often chosen from body systems such as the endocrine system (type 1 or type 2 diabetes), respiratory system (asthma, COPD), circulatory system (coronary heart disease), nervous system (Parkinson’s disease, multiple sclerosis), musculoskeletal system (osteoarthritis) or cancers. Choose two from different systems so your comparisons have something to work with.
Learning aims for Unit 14 Physiological Disorders and their Care
| Learning aim | What it covers |
|---|---|
| A: Investigate the causes and effects of physiological disorders | Genetic, lifestyle and environmental causes; signs (what others can observe or measure) and symptoms (what the person experiences); effects on body systems and on physical, intellectual, emotional and social wellbeing. |
| B: Examine the investigation and diagnosis of physiological disorders | Measurements and tests such as blood tests, blood pressure, peak flow and spirometry, imaging (X-ray, CT, MRI), biopsies and ECG; how results confirm or rule out a diagnosis. |
| C: Examine treatment and support for service users with physiological disorders | Medication, surgery, therapies and lifestyle changes; formal carers (GP, specialist nurse, physiotherapist) and informal carers (family, friends); care settings such as home, GP surgery, hospital and residential care. |
| D: Develop a treatment plan for service users with physiological disorders to meet their needs | Assessing a person’s needs, planning treatment and support, setting goals, review points, and explaining how the plan improves health and wellbeing. |

How to answer Learning aim A: causes and effects
Keep causes, signs and symptoms separate – mixing them up is one of the most common reasons A.P1 is not met. For A.M1, start from how the body system normally works, then explain exactly what changes.
- Causes: genetic, lifestyle (diet, smoking, inactivity), environmental, age-related.
- Signs: measurable or visible, such as raised blood glucose, wheezing, high blood pressure.
- Symptoms: reported by the person, such as tiredness, breathlessness or pain.
- Effects: on the system itself, on other systems, and on PIES wellbeing.
Example paragraph: In type 2 diabetes the pancreas still produces insulin, but body cells – particularly in muscle, fat and the liver – respond to it less well. This insulin resistance means glucose stays in the bloodstream instead of entering cells, so blood glucose rises. Over time the beta cells in the pancreas struggle to keep up with demand and insulin output can fall. Persistently high glucose damages small blood vessels, which explains why the disorder affects other systems: the retina in the eye, the kidneys and the nerves in the feet. This is why a disorder of the endocrine system also becomes a circulatory and nervous system problem.
How to answer Learning aim B: investigation and diagnosis
For B.P2, compare rather than describe – a side-by-side table followed by a paragraph on key differences works well. For B.M2, focus on the procedure that actually confirms the diagnosis and explain why other findings alone are not enough.
Example paragraph: Both asthma and type 2 diabetes can be suspected from symptoms, but neither should be diagnosed on symptoms alone. For diabetes, an HbA1c blood test is particularly important because it reflects average blood glucose over roughly the previous two to three months, so a single high reading after a meal does not lead to a wrong diagnosis. Asthma relies more on tests of airway function, such as spirometry, peak flow monitoring or FeNO testing. These are less straightforward than a blood test because results vary from day to day, which is why more than one test is often needed before a diagnosis is confirmed.
How to answer Learning aim C: treatment, support and care
- Treatment: medication, surgery, physiotherapy, dietary change, exercise programmes.
- Support: specialist nurses, education programmes, charities and support groups.
- Carers: formal (GP, practice nurse, consultant, dietitian, physiotherapist) and informal (family members, friends, neighbours).
- Settings: own home, GP surgery, outpatient clinic, hospital, residential or nursing home.
For C.M3, assess how well this provision actually works for service users. Consider waiting times, access in rural areas, the role of informal carers and how well services co-ordinate with each other.
How to answer Learning aim D: the treatment plan
- Service user profile (anonymised – use a pseudonym)
- Assessment of needs under physical, intellectual, emotional and social headings (D.P5)
- Treatment plan table: need, goal, action, who is responsible, timescale (D.P6)
- How each action improves health and wellbeing (D.P7)
- Review points with measurable indicators and planned adjustments (D.M4)
- Justification of recommendations against alternatives (D.D3)
Example paragraph: Mr A’s main physical need is to lower his HbA1c and reduce his risk of complications. The plan recommends a structured diabetes education course as the first step, rather than adding a second medication straight away. This is because Mr A said he does not understand which foods raise his blood glucose, and education addresses that gap directly, while also supporting his emotional need to feel in control. The disadvantage is that results will take several months to show, so the plan includes a review with the practice nurse after three months, when his HbA1c will be checked and medication reconsidered if it has not improved.
Worked example: a mini case analysis
Case: Mr A, aged 58, has recently been diagnosed with type 2 diabetes. He works as a delivery driver, lives with his wife, and is overweight. He feels tired, worries about losing his job and does not enjoy exercise.
| Need area | Identified need | Planned action | Expected benefit |
|---|---|---|---|
| Physical | Lower blood glucose and weight | Medication as prescribed by GP, dietitian referral, walking during breaks | Lower HbA1c, reduced risk of eye, kidney and nerve damage |
| Intellectual | Understand the condition | Structured education course and reliable NHS information | Confident self-management |
| Emotional | Anxiety about job and health | Discussion with practice nurse; guidance from GP on any driving-related requirements | Reduced worry, better engagement with treatment |
| Social | Wife does the cooking; meals out with colleagues | Include his wife in dietitian sessions | Support at home makes changes easier to sustain |
Analysis: the plan works because each action targets a specific need, and several actions meet more than one need – including his wife helps both physically (diet) and socially (shared change). The main weakness is that it depends on Mr A’s motivation, so a review point and a named professional to follow up are essential. That judgement is the type of reasoning D.M4 and D.D3 reward.
Common mistakes that cost marks
- Confusing signs with symptoms, or listing them without explaining their causes.
- Choosing two disorders from the same body system, which weakens the comparisons in B.P2 and C.P4.
- Describing tests one after another instead of comparing them.
- Writing about treatment in general terms rather than for the specific disorder.
- Treatment plans with no review dates or measurable goals, which blocks D.M4.
- Using a real person’s name or identifiable details – always anonymise.
- Copying medical websites; assessors expect explanation in your own words with references.
How to move from Merit to Distinction
- A.D1: do not just list effects – weigh them. Which impact matters most for this person and why, and how do impacts interact (for example, pain leading to inactivity, isolation and low mood)?
- BC.D2: justify each investigation and treatment by setting its benefits against risks, cost, invasiveness and the person’s preferences.
- D.D3: for each recommendation, compare it with at least one alternative and explain why yours suits this service user better.
- Use current UK sources such as NHS and NICE guidance, and reference them consistently.
FAQs
Which disorders should I choose for Unit 14?
Pick two disorders from different body systems that have clear diagnostic tests and a range of treatments – for example type 2 diabetes and asthma, or coronary heart disease and osteoarthritis. Check whether your brief restricts the choice.
Is Unit 14 the same as the old Unit 14 Physiological Disorders?
The older QCF BTEC Nationals (2010) also had a Unit 14 Physiological Disorders with P1–P5 style criteria. The current 2016 specification, which this guide follows, uses learning aims A–D and codes such as A.P1 and BC.D2.
What is the difference between a sign and a symptom?
A sign can be observed or measured by someone else, such as a high temperature or raised blood pressure. A symptom is experienced and reported by the person, such as pain, dizziness or fatigue.
Can I use a real person for the treatment plan?
Many centres provide a case study. If you base it on someone you know, you must have permission, change their name and remove identifying details to respect confidentiality.
How many sources should I reference?
There is no set number, but using recognised UK sources such as NHS, NICE and relevant charities, and referencing them consistently, makes your explanations more credible.
