The figure below shows the generic sequence of spaces and direction of movement of users to and from an operation theatre after entering from a common corridor. The spaces are marked as \(P\), \(Q\), \(R\), \(S\). Choose the correct option(s). Arrows indicate flow of different users
Show Hint
Trace each arrow's direction and zone: one way in before surgery = pre-operative, two way through the change area = dress change, one way out to soiled area = dirty utility, one way out to corridor after surgery = post-operative.
Step 1: Read the zoning and the arrows.
The plan is split into a semi-sterile zone and a sterile zone by the dashed line, with the sterile zone holding the Operation Theatre itself.
Three separate arrows connect the common corridor to the block: one goes straight in to \(Q\) and then down into the Operation Theatre, one is a two way arrow through \(P\) into the Operation Theatre, and one comes out of the Operation Theatre through \(S\) back to the corridor. \(R\) sits outside the sterile boundary with a one way arrow leading out of the Operation Theatre.
Step 2: Work out what each space does.
\(Q\) is entered straight from the corridor, crossing both zones in one direction only, before the user reaches the theatre. This is the route a patient takes on a trolley before surgery, so \(Q\) is the pre-operative holding space.
\(P\) sits in the semi-sterile zone and has a two way arrow both to the corridor and to the theatre, because staff go there to change into sterile OT clothing before entering the theatre and pass through it again afterwards, so \(P\) is the dress change room.
\(R\) is reached only by a one way arrow leading out of the theatre, and it sits outside the controlled zone altogether, matching the space where soiled instruments, linen and waste leave the theatre without re-entering the sterile area, so \(R\) is the dirty utility.
\(S\) is reached by a one way arrow out of the theatre that leads straight back to the corridor, matching the route a patient takes after the operation is done, so \(S\) is the post-operative space.
Step 3: Test the options.
Option (A) keeps \(Q\) as pre-operative and \(R\) as dirty utility, both right, but calls \(S\) "dress change", which is wrong since \(S\) is the post-operative exit route, so (A) fails.
Option (B) gives \(P\) - Dress change, \(Q\) - Pre-operative, \(R\) - Dirty utility, all three matching Step 2, so (B) is correct.
Option (C) gives \(P\) - Dirty utility, \(R\) - Dress change, \(S\) - Pre-operative, all three swapped against Step 2, so (C) fails.
Option (D) gives \(P\) - Dress change, \(R\) - Dirty utility, \(S\) - Post-operative, all three matching Step 2, so (D) is correct.
Final Answer:
Options (B) and (D) give the correct labelling of the operation theatre suite.
\[ \boxed{(B), (D)} \]
