Mastery ensures effective nutritional support, medication administration, or gastric decompression, while prioritising patient dignity, safety, and professional accountability.
Assessment criteria
Topic Overview
The TQUK Level 3 Diploma in Healthcare Support Work (RQF) is designed for individuals working or aspiring to work in healthcare settings such as hospitals, care homes, or community health services. This qualification covers essential knowledge and skills for providing high-quality, person-centred care and support to patients, clients, and their families. It includes topics like communication, health and safety, infection control, and supporting individuals with their physical and emotional needs, ensuring you are well-prepared to work effectively as a healthcare support worker.
This diploma is crucial because it equips you with the practical and theoretical understanding needed to assist registered healthcare professionals, such as nurses and midwives, in delivering safe and compassionate care. It aligns with the Care Certificate and national standards, making it a recognised pathway into the healthcare sector. By mastering this content, you will be able to contribute to improving patient outcomes, promoting dignity and independence, and working within legal and ethical frameworks.
Within the broader Health & Social Care curriculum, this diploma sits at Level 3, indicating a more advanced understanding compared to Level 2 qualifications. It builds on foundational knowledge and prepares you for supervisory roles or further study, such as nursing or allied health professions. The qualification emphasises reflective practice and continuous professional development, ensuring you can adapt to the evolving demands of the healthcare environment.

Learning Objectives
What you need to know and understand
- 1. Understand current legislation, national guidelines, policies, procedures, and protocols in relation to inserting and securing nasogastric tubes.2. Understand purpose and functions of nasogastric tubes and associated procedures.3. Be able to prepare for the insertion of a nasogastric tube.4. Be able to insert a nasogastric tube.5. Be able to measure, record and dispose of nasogastric aspirate following policies, procedures, and protocols.
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for demonstrating a thorough understanding of relevant legislation, including the Mental Capacity Act 2005, and national guidelines, such as those from the National Patient Safety Agency, before the procedure.
- Award credit for accurately explaining the purpose of nasogastric intubation, including for nutrition, medication, or gastric drainage, and the associated potential complications.
- Award credit for performing thorough hand hygiene, selecting appropriate personal protective equipment, and preparing the patient and equipment in line with infection control policies.
- Award credit for correctly measuring and lubricating the tube, gently inserting it to the predetermined depth, and checking for initial correct placement using aspiration and pH testing, not auscultation.
- Award credit for securely fixing the tube with a suitable dressing, documenting the procedure accurately, and disposing of aspirate according to local protocols.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always treat practical assessments as real clinical encounters; narrate your actions to demonstrate underpinning knowledge, such as explaining why you are discarding the first aspirate sample if it is not pH-adequate.
- 💡Before the assessment, mentally rehearse emergency protocols for complications like respiratory distress or inadvertent tube misplacement, and be ready to articulate your actions.
- 💡Use the assessment to showcase person-centred care by discussing how you maintained the patient’s comfort and dignity, for example, by offering mouth care after the procedure.
- 💡Familiarise yourself with your organisation’s specific policies on nasogastric tube care, as evidence of following local protocols is often a key assessment criterion.
- 💡When answering questions about legislation, always link the law to a practical example from your workplace or case study. For instance, explain how the Health and Safety at Work Act 1974 applies to manual handling tasks.
- 💡Use the acronym 'PIES' (Physical, Intellectual, Emotional, Social) to structure answers about holistic care. This shows you understand the full range of needs and can demonstrate comprehensive support planning.
- 💡In reflective accounts, use the Gibbs Reflective Cycle (Description, Feelings, Evaluation, Analysis, Conclusion, Action Plan) to demonstrate deep learning and professional growth. Avoid simply describing what happened; analyse why and how you can improve.
Common Mistakes
Common errors to avoid in your coursework
- Using the 'whoosh test' (air auscultation) as the sole method to confirm tube placement, which is unreliable and not endorsed by guidelines.
- Failing to check that the patient has provided valid, informed consent, or not appropriately assessing capacity for individuals who may lack it.
- Measuring the tube from the tip of the nose to the earlobe and then to the xiphisternum incorrectly, leading to an unsafe insertion depth.
- Not securing the tube with a purpose-designed nasal dressing, causing displacement and potential harm, such as aspiration pneumonia.
- Overlooking the importance of checking gastric residual volumes before each feed or medication administration, which can indicate intolerance.
- Misconception: Healthcare support workers can diagnose conditions or prescribe treatments. Correction: Support workers work under the supervision of registered professionals and must not exceed their scope of practice; they observe and report changes but do not diagnose.
- Misconception: Confidentiality means never sharing any information. Correction: Confidentiality can be breached if there is a risk of harm to the individual or others, or if required by law (e.g., safeguarding concerns). You must follow your organisation's information governance policies.
- Misconception: Person-centred care is just being nice to patients. Correction: It involves actively involving individuals in decisions about their care, respecting their choices, and adapting support to their unique circumstances, not just being polite.
