Try this with join query statements

CREATE PROCEDURE [dbo].[deleteItem]
@ItemId int = 0 
AS
 Begin
 DECLARE @cnt int;

SET NOCOUNT ON
SELECT @cnt =COUNT(ttm.Id) 
    from ItemTransaction itr INNER JOIN ItemUnitMeasurement ium 
        ON itr.Id = ium.ItemTransactionId  INNER JOIN ItemMaster im 
        ON itr.ItemId = im.Id INNER JOIN TransactionTypeMaster ttm 
        ON itr.TransactionTypeMasterId = ttm.Id 
        where im.Id = @ItemId

if(@cnt = 1)
    Begin
    DECLARE @transactionType varchar(255);
    DECLARE @mesurementAmount float;
    DECLARE @itemTransactionId int;
    DECLARE @itemUnitMeasurementId int;

        SELECT @transactionType = ttm.TransactionType,  @mesurementAmount = ium.Amount, @itemTransactionId = itr.Id, @itemUnitMeasurementId = ium.Id
        from ItemTransaction itr INNER JOIN ItemUnitMeasurement ium 
            ON itr.Id = ium.ItemTransactionId INNER JOIN TransactionTypeMaster ttm 
            ON itr.TransactionTypeMasterId = ttm.Id 
            where itr.ItemId = @ItemId  
        if(@transactionType = 'Close' and @mesurementAmount = 0)
            Begin
                delete from ItemUnitMeasurement where Id = @itemUnitMeasurementId;

            End
        else
            Begin
                delete from ItemTransaction where Id = @itemTransactionId;
            End
