Reveal the answer and explanation

Correct answer: C — Prepared CSCI syringes should ideally be used immediately and should NOT be stored for more than 24 hours — stability data apply to freshly prepared solutions

Explanation lettering: D = shown as A · E = shown as B · B = shown as C · A = shown as D · C = shown as E

Option B is correct. Current UK palliative care guidance mandates preparation of a new syringe every 24 hours, noting that chemical and physical stability data only support 24‑hour use of freshly prepared solutions ([rightdecisions.scot.nhs.uk](https://www.rightdecisions.scot.nhs.uk/shared-content/palliative-care-syringe-pumps/practice-points-syringe-pumps-syringe-drivers/?utm_source=openai)). The BodyGuard T protocol specifies that medications should be made up immediately before use and are stable for 24 hours ([rightdecisions.scot.nhs.uk](https://www.rightdecisions.scot.nhs.uk/nhs-borders-clinical-guidelines/adult-acute-services/in-patient-guidelines/nursing/bodyguard-t-syringe-pump-protocol/?utm_source=openai)). Distractors: A (1 month refrigerated) and C (7 days room temperature) far exceed supported stability data; D is clearly incorrect (no expiry) and E incorrectly restricts to diamorphine when the principle applies to all CSCI preparations.
