Assessment Guidance
Guidance for achieving higher grades
- 💡Always follow the 'right patient, right test, right sample' principle and re-check details against wristband and request form.
- 💡Demonstrate comprehensive understanding of aseptic non-touch technique (ANTT) and articulate its importance during observed assessments.
- 💡Refer to local policies and manufacturer’s instructions for the specific central line type to ensure safe practice.
- 💡In written or reflective accounts, explicitly link your actions to relevant legislation and guidelines (e.g., Health and Safety at Work Act, local infection control policy).
- 💡Use the SPECS acronym (Situation, Problem, Effect, Cause, Solution) to structure answers on problem-solving scenarios.
- 💡Always link theory to practice by giving real-world examples from placements or case studies.
- 💡In 6-mark questions, allocate time to plan: aim for 3 developed points with explanations and examples.
Common Mistakes
Common errors to avoid in your coursework
- Failing to flush the line adequately before and after collection, leading to clotted samples or line occlusion.
- Using an incorrect order of draw when multiple tubes are required, causing cross-contamination of additives.
- Incorrectly identifying the patient or mislabeling tubes, breaching positive patient identification protocols.
- Re-sheathing needles or improper disposal of sharps, increasing the risk of needlestick injury.
- Forgetting to remove the tourniquet (if used for peripheral collection) or not releasing pressure on the central line hub before sample aspiration, causing haemolysis or backflow.
- Misconception: Healthcare support workers can diagnose conditions. Correction: They are not qualified to diagnose; they report observations to registered professionals.
- Misconception: Hand hygiene is only necessary after contact with bodily fluids. Correction: Hand hygiene must be performed before and after every patient contact, even if gloves are worn.
- Misconception: Confidentiality means never sharing information. Correction: Information can be shared with the care team on a need-to-know basis, and in cases of risk, with relevant authorities.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A patient has a fluid intake of 1500 ml over 24 hours and an output of 1200 ml. Calculate the fluid balance and state whether it is positive or negative.
- 1.Step 1: Identify the given values: intake = 1500 ml, output = 1200 ml.
- 2.Step 2: Subtract output from intake: 1500 - 1200 = 300 ml.
- 3.Step 3: Since intake exceeds output, the balance is positive. State the result with units: +300 ml.
Question: Describe how you would correctly measure and record a patient's blood pressure using a manual sphygmomanometer.
- 1.Step 1: Ensure the patient is relaxed and seated with arm supported at heart level.
- 2.Step 2: Wrap the cuff around the upper arm, aligning the artery marker with the brachial artery.
- 3.Step 3: Inflate the cuff to 30 mmHg above the palpated radial pulse, then slowly deflate while listening with a stethoscope over the brachial artery.
- 4.Step 4: Record the systolic pressure (first Korotkoff sound) and diastolic pressure (point where sounds disappear) as mmHg, e.g., 120/80 mmHg.
