E/m hpi elements

Do you give HPI credit for the elements documented referring to the associated signs and symptoms? See example below

Mother states: no urination for the last 12 hours and fever today 100 F.

These are associated signs and symptoms that document Duration and Severity. Is this double dipping since we already give them credit for the associated sign and symptom?

How many HPI elements do you pull from the below scenario?

SUBJECTIVE
