I'm assuming you don't want any other session to be able to read the row while this specific query is running...

Wrapping your SELECT in a transaction while using WITH (XLOCK,READPAST) locking hint will get the results you want. Just make sure those other concurrent reads are NOT using WITH (NOLOCK). READPAST allows other sessions to perform the same SELECT but on other rows.

BEGIN TRAN
  SELECT *
  FROM  WITH (XLOCK,READPAST) 
  WHERE RowId = @SomeId

  -- Do SOMETHING

  UPDATE 
  SET =@somevalue
  WHERE RowId=@SomeId
COMMIT
