An older female client comes to the clinic for a regular check- up

An older female client comes to the clinic for a regular check- up. The client tells the nurse that she has increased her daily doses of acetaminophen (Tylenol) for the past month to control joint pain. Based on this client's comment, which previous lab values should the nurse compare with today's report?

a.     Determine if there a decrease in serum potassium due to renal compromise

b.    Look for an increase in today's LDH compared to the previous one to assess for possible liver damage

c.     Expect to find an increase in today's APTT as compared to last quarter's due to bleeding
