Title of Access to HE Diploma: Nursing, Nursing in Work and Health and Human Sciences
Unit title: Nutrition, Digestion and Excretion
Unit code: CBB040 (6 credits)
Description of Assignment:
Task 1 (AC 1.1, 2.1, 2.2, 2.3, 2.4) – Review the attached case study.
a) Write a letter to Mrs Smith explaining the importance of good nutrition for optimum health,
ensuring that you distinguish the varying functions of the main nutrient groups. In your letter you
should also explain to Mrs Smith why she might need to take supplements of vitamins and minerals
and the need to drink a suitable amount of water for her weight. The letter should be around
700 words (+/- 10%).
b) Attach a one-day diet plan for her and, in the space below the table, explain how the body
uses carbohydrates, lipids, proteins, vitamins, minerals and water
(use no more than 700 words for your explanation). Evaluate each meal in your chart by showing its
nutritional content. Use the food plate chart to help you.
c) In the chart provided, evaluate through comparisons the three disorders that are caused as a result of malnutrition, specifically calcium and vitamin D deficiency (rickets, tetany and osteoporosis).
Your letter should follow formal letter writing conventions (e.g. address, formal greeting, paragraphs
and ending). All parts of the task should be referenced in-text using the Harvard system and you will
need to attach a reference list separately to cover all three parts of Task 1.
Task 2 (AC 3.1, 3.2)
Produce an explanatory leaflet for an Access to HE learner on another course who does not
understand how the digestive system works. In it, you will need to describe the main organs
involved in digestion and then explain their function in relation to the digestion of food.
You will need to reference your work in-text and attach a reference list using the Harvard System.
You may use images or your own drawings in your leaflet to illustrate and support your own explanations,
do not use them instead of your own explanations. Ensure that you acknowledge the source of the images.
You should write in an academic tone using the 3rd person, avoid the use of the
1st and 2nd person (I or you).
Task 3 (AC 4.1)
Explain the three metabolic processes of cellular respiration: glycolysis, the tricarboxylic
acid cycle (TCA) and oxidative phosphorylation in a flow chart format. Include other ways the
body breaks down nutrients into usable products together with the process of lipolysis and
how triglycerides are stored and used in the body; protease enzymes in breaking down
proteins; deamination of amino acids and how ammonia is converted to urea.
Task 4 (AC 5.1, 5.2, 5.3)
Complete an in-class viva voce (oral examination) on the liver. This task will help you to
demonstrate how you can recall factual information and relevant scientific terminology.
To prepare for the task, you should draw or find a diagram of the liver, which you will bring
into the viva. The assessor will give you clear initial instructions and may prompt you
as required and ask questions that are relevant to the aspects that you are discussing.
Your viva will be recorded.
· The viva will be approximately 12 minutes and will take place on w/b 25th November 2019
· You will not be permitted to take your own notes into the viva.
Task 5 (AC 6.1, 6.2, 6.3)
End of Unit Controlled Assessment of 1½ hours’ duration on the structure and role of the
kidneys in excretion.
The controlled assessment will take place on w/b 9th December 2019. If you require extra time
or other assistance for the controlled assessment, this should be brought to the attention of
your tutor by the 29th November 2019 so that the request can be considered and, if agreed,
suitable arrangements made.
Examination rules and procedures
- Arrive for the controlled assessment early. If you arrive after the controlled assessment
- has started, you will not be permitted to enter the examination room as it would disturb
- your fellow students.
- Mobile telephones must be switched off and placed out of reach.
- You will be provided with a question and answer booklet.
- You are permitted to use some pens, pencils, a ruler and a rubber. You may have a
- bottle of water on your desk.
- All your other personal belongings need to be left at the front of the room away from
- the desks. You are not permitted to bring any notes into the examination.
- Once the controlled assessment has started you must not communicate with anyone
- except the invigilator. If you need to communicate with the invigilator, you should raise
- your hand and wait for her/him to come to you.
- You need permission from the invigilator to leave the examination room (e.g. to go to the toilet).
- If you leave the room then you may not take the question paper or your answer booklet
- with you. If you leave without permission then you will not be permitted to re-enter
- the examination.
- You should not leave your desk until all your papers/scripts have been collected.
- You should not speak to your peers until you have left the examination room.
- Any learners found to have broken the rules of examination will have their scripts
- automatically invalidated. This means that you will have to undertake
- a resubmission examination.
Preparing for the examination
· Make sure that you have read the assessment criteria (6.1, 6.2 and 6.3) and grade guidance
so that you know what to revise and what is expected from your answers.
· If you normally need to be contactable by phone, ensure that those who may contact you
are aware of the times that you will be in the examination and will not have access to your phone.
- If you require special conditions for sitting tests (e.g. extra time), inform your tutor by the
- 29th November days before the test so that they can confirm whether you are eligible for these accommodations and make appropriate arrangements.

These explanations need to be written in an academic style, avoiding use of the first and
second personal pronouns, whereas the letter to Mrs Smith will be addressed to her.
Make sure you fully reference your work in text and include a reference list using the
Harvard System of Referencing.
