15. Noah is asked about isolation / transmission-based precautions in a NCFE Healthcare Science paper.
16. Noah is asked about decontamination in a NCFE Healthcare Science paper.
17. Hand gel contact time 20 s. Gels in a 10-minute run if one every 2 min?
18. A bay of 6 beds, 2 isolated. Percentage isolated?

23. Noah carries out a T-Level occupational task on infection prevention and control. This is a typical NCFE required-practical style question.
(a) [2 marks]
- Independent: the factor being investigated
- Dependent: the measured result or quality check
(b) [2 marks]
- follow the SOP and keep other variables constant
- so the test is fair / only one variable is changed
(c) [2 marks]
- not recording the batch/lot number or operator ID
24. Noah carries out writing or following an SOP for infection prevention and control. This is a typical NCFE required-practical style question.
(a) [2 marks]
- Independent: a step in the method
- Dependent: whether the acceptance criteria are met
(b) [2 marks]
- same calibrated instrument
- so the test is fair / only one variable is changed
(c) [2 marks]
- skipping a verification check
25. Noah carries out a COSHH / risk-assessment review for infection prevention and control. This is a typical NCFE required-practical style question.
(a) [2 marks]
- Independent: hazard
- Dependent: control measure effectiveness
(b) [2 marks]
- same PPE and waste route
- so the test is fair / only one variable is changed
(c) [2 marks]
- using expired reagents or the wrong waste stream
26. Noah carries out data review in a LIMS or quality log for infection prevention and control. This is a typical NCFE required-practical style question.
(a) [2 marks]
- Independent: sample ID
- Dependent: result vs specification
(b) [2 marks]
- same calculation method
- so the test is fair / only one variable is changed
(c) [2 marks]
- transcription error between the instrument and the LIMS
