obtaining the patient's medication history, the nurse learns that the patient experienced a rash when
given amoxicillin [Amoxil] as a child 20 years earlier. What will the nurse do? - CORRECT ANSWER-
Request an order ḟor a skin test to assess the current risk.

PO. What will the nurse do? - CORRECT ANSWER-Question the need ḟor a penicillinase-resistant
penicillin.

[Amoxil] and not ampicillin [Unasyn]. What will the nurse tell the parent? - CORRECT ANSWER-Ampicillin
is not as acid stable as amoxicillin.
