IF :SYSTEM.CURRENT_ITEM = 'REMARKS' THEN
SET_ITEM_PROPERTY('VISITS.REMARKS', CURRENT_RECORD, HEIGHT, 30);
ELSE
SET_ITEM_PROPERTY('VISITS.REMARKS', CURRENT_RECORD, HEIGHT, 16);
END IF;

And if you check the form builder help topic for set_item_instance_property you'll see it can't modify height. Set_item_property can, if you supply the correct parameters.

Seriously?
The start of the help topic lists all the different ways you can call set_item_property with the full parameter lists.
Below that it explains what each parameter is and what values you can use.
At the end is actual examples of how to call it.
The help topic is as comprehensive as anyone can possibly need.
I suggest you take some time to read it.
If there's a particular point you don't understand don't hesitate to ask, but everything you need is there.

Since you are setting the properties of the Item and not an Instance of and Item, you do not pass the CURRENT_RECORD value to the SET_ITEM_PROPERTY() built-in. This variable is only valid with the Set_Item_Instance_Property() built-in. Consequently, by changing the height of the item using Set_Item_Property() you will be changing the height of ALL instances of the Item.
If you need to change the height of just one instance of the item, I'm afraid you can't do this. The typical work-around for this would be to create a Visual Attribute (VA) object and then assign the VA to the item during run time, but when I tested this, the "Add Property" button in the VA Property Pallet was disabled otherwise I would have suggested you add the Height property to the VA. Here is the problem with changing the height of just one instance of an item in a multi-record block - Forms would have to increase the spacing between the rest of the items in the row in order to accomodate the new height of the item or Forms would have to display the new height by overlaying the item on corresponding items in preceding and subsequent rows.
Perhaps you could display the text in your Text-Item in a Tooltip (bubble hint) or in a display text item instead of changing the height of your text-item object.
