Select distinct from a table foreach value from another - sql-server

Question

I have a view that gets the status for each category for each venue.
I need to display all of the above, but only the latest in the status for each category for each venue.
A general idea could be, for each item in a shop, there is a status. So for the cucumbers, letters, and tomatoes in shop A, the status would be good good bad respectively. Same for shop B, C etc. Now these statuses can be updated at any time - but only the latest update should be displayed.
I have tried to create a view such as the following:
SELECT
dbo.vwVenues.HospitalID
, dbo.vwVenues.Hospital AS hospitalName
, dbo.tblVenueStatus.id AS statusId
, dbo.tblVenueStatusName.statusName
, dbo.tblVenueStatusCategories.categoryName
, dbo.tblVenueStatus.dateAdded AS statusDateAdded
, dbo.tblVenueStatus.loggedBy AS statusLoggedBy
, dbo.tblVenueStatusNotes.noteContent
, dbo.tblVenueStatusNotes.dateAdded AS noteDateAdded
, dbo.tblVenueStatusNotes.removed AS noteRemoved
, dbo.tblVenueStatus.resolved AS statusResolved
, dbo.tblVenueStatus.resolveDate AS statusResolveDate
, dbo.tblVenueStatus.removed AS statusRemoved
, dbo.tblVenueStatus.dateRemoved AS statusRemovedDate
, dbo.tblVenueStatus.categoryId
FROM
dbo.tblVenueStatusName
RIGHT OUTER JOIN dbo.tblVenueStatusNotes
RIGHT OUTER JOIN dbo.tblVenueStatus
ON dbo.tblVenueStatusNotes.id = dbo.tblVenueStatus.noteId
LEFT OUTER JOIN dbo.tblVenueStatusCategories
ON dbo.tblVenueStatus.categoryId = dbo.tblVenueStatusCategories.id
ON dbo.tblVenueStatusName.id = dbo.tblVenueStatus.statusNameId
FULL OUTER JOIN dbo.vwVenues
ON dbo.tblVenueStatus.venuId = dbo.vwVenues.HospitalID
I get all the venues, but I get all the statuses for each category, instead of just the latest. Even trying to phrase the question right was hard - so my current search yeilded nothing.
Could anyone please help?

CREATE TABLE [dbo].[tblVenueStatus](
[id] [int] IDENTITY(1,1) NOT NULL,
[statusNameId] [int] NOT NULL,
[venuId] [int] NOT NULL,
[categoryId] [int] NOT NULL,
[loggedBy] [nvarchar](50) NOT NULL,
[noteId] [int] NOT NULL,
[dateAdded] [datetime] NOT NULL,
[resolved] [tinyint] NOT NULL,
[resolveDate] [datetime] NULL,
[removed] [tinyint] NOT NULL,
[dateRemoved] [datetime] NULL,
CONSTRAINT [PK_tblSiteVenuStatus] PRIMARY KEY CLUSTERED
CREATE TABLE [dbo].[tblVenueStatusCategories](
[id] [int] IDENTITY(1,1) NOT NULL,
[categoryName] [nvarchar](50) NOT NULL,
[categoryDescription] [nvarchar](150) NULL,
CONSTRAINT [PK_tblVenueStatusCategories] PRIMARY KEY CLUSTERED
CREATE TABLE [dbo].[tblVenueStatusName](
[id] [int] IDENTITY(1,1) NOT NULL,
[statusName] [nvarchar](50) NOT NULL,
[statusDescription] [nchar](150) NULL,
CONSTRAINT [PK_tblVenuStatusName] PRIMARY KEY CLUSTERED
CREATE TABLE [dbo].[tblVenueStatusNotes](
[id] [int] IDENTITY(1,1) NOT NULL,
[noteContent] [nvarchar](500) NULL,
[dateAdded] [datetime] NOT NULL,
[removed] [tinyint] NOT NULL,
[dateRemoved] [datetime] NULL,
CONSTRAINT [PK_tblVenueStatusNotes] PRIMARY KEY CLUSTERED
Desired Output will be:
Venu Name | Category 1 Status | Category 2 Status

Try something like this. It's largely sumerised because of what you said you needed to see in your sample. Try this and let me know if it helps. You can add other columns you need here, It is taking the latest status in each category for each hospital, and showing all hospitals and categories in a easily readable grid.
SELECT * FROM
(
SELECT VwV.HospitalID, vwV.Hospital, ISNULL(vStatusName.statusName, '') AS statusName, vStatusCategories.categoryName
FROM
(
SELECT topStatus.HospitalID, topStatus.categoryId, sta2.id
FROM
(
SELECT HospitalID, categoryId, MAX(sta.dateAdded) AS DateAdded
FROM vwVenues
INNER JOIN tblVenueStatus sta ON sta.venuId = dbo.vwVenues.HospitalID
GROUP BY HospitalID, categoryId
) topStatus
INNER JOIN tblVenueStatus sta2 ON sta2.dateAdded = topStatus.DateAdded AND sta2.venuId = topStatus.HospitalID) Statuss
FULL OUTER JOIN vwVenues vwV ON vwV.HospitalID = Statuss.HospitalID
LEFT OUTER JOIN tblVenueStatus vStatus ON vStatus.id = Statuss.id
LEFT OUTER JOIN tblVenueStatusName vStatusName ON vStatusName.id = vStatus.statusNameId
LEFT OUTER JOIN tblVenueStatusCategories vStatusCategories ON vStatus.categoryId = vStatusCategories.id AND vStatusName.id = vStatus.statusNameId
LEFT OUTER JOIN tblVenueStatusNotes vStatusNotes ON vStatusNotes.id = vStatus.noteId
) AS s
PIVOT (MIN(StatusName)
FOR [CategoryName] IN ([Category1],[Category2])) AS PTbl
