How do I delete a row from a Parse object?

I have a class on Parse.com called "Hospital", which has a few rows on it. I want to query all the rows in this object, and then selectively delete some of them.

I figure I need to cycle through the object, gathering the objectIDs, and then look at the row associated with each ID to figure out which ones should be deleted. I can't find how to do this anywhere. I've tried this: 

PFQuery *query = [PFQuery queryWithClassName:@"Hospital"];

But this returns an object with 0 objects inside it, when there is definitely a row in the Parse.com database.

Once I get this part working, and get objectIDs, it seems I can delete a row with the following: 

PFObject *testObject = [PFObject objectWithoutDataWithClassName:@"Hospital" objectId:@"NMZ8gLj3RE"];
 [testObject deleteInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
 if (succeeded){
 NSLog(@"BOOOOOM"); // this is my function to refresh the data
 } else {
 NSLog(@"DELETE ERRIR");
 }
 }];

PFQuery *query = [PFQuery queryWithClassName:@"Hospital"];
[query findObjectsInBackgroundWithBlock:^(NSArray *hospitals, NSError *error) {
    if (!error)
    {
        for (PFObject *hospital in hospitals)
        {
            if ([hospital.objectId isEqualToString:@"NMZ8gLj3RE"])
            {
                [hospital deleteInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
                    if (succeeded){
                        NSLog(@"BOOOOOM"); // this is my function to refresh the data
                    } else {
                        NSLog(@"DELETE ERRIR");
                    }
                }];
            }
        }
    }
    else
    {
        NSLog(@"%@",error);
    }

}];
