C
The mechanism of action of penicillin allergy toxicity is best described as:
A) Cell walls in human skin are destroyed by penicillin resulting in the characteristic rash seen in penicillin allergy
B) Penicillin breakdown products form haptens which bind to cell surface proteins to form an antigen. The major breakdown product results from the degradation of the 4 member ring structure, and the minor breakdown product results from the degradation of the 5 member ring
C) Penicillin breakdown products act to release beta lactamase which results in the allergic reaction
D) Susceptible bacteria release allergic components in an effort to convince the patient to stop taking their medicine
B
NSAIDs and opioids promote histamine release via:
A) IgE mediated type I reaction
B) Direct pharmacologic effect
C) Promotion of prostaglandin synthesis
D) Activation of central pathways that promote appreciation of pain
B
When selecting an opioid for a patient claiming an allergy to codeine:
A) Choose morphine, the active metabolite of codeine
B) All patients claiming an allergy to codeine should not receive an analgesic
C) If there is a compelling reason to use an opioid you should choose an opioid such as fentanyl or meperidine because these opioids are chemically distinct from codeine
D) There is no risk of allergic reactions from opioids
C
An allergic reaction to a nonantibacterial sulfonamide such as celecoxib in a patient with an allergy to sulfamethoxazole may be due to:
A) Both drugs have an arylamine group at the N4 position of the sulfonamide moiety
B) Both drugs have a 5 or 6 member nitrogen containing ring at the N1 nitrogen
C) A predisposition to drug-induced allergic reactions
D) Circulating IgE antibodies to sulfamethoxazole
C
Your patient today has a serious bacterial infection that is best treated with a penicillin or a cephalosporin. Your patient also reports a penicillin allergy. Use the recommendations found in the teachable moment table in slide 23. Match the following patient reports with the best course of action. A match should only be used once.
A type II-IV HSR
A) OK to use a third or fourth generation cephalosporin but only by test dose procedure. Other penicillins and cephalosporins should only…
B) Use third or fourth generation cephalopsorin, or carbapenem, or if necessary use a penicillin by test dose procedure
C) Avoid using a penicillin or a cephalosporin or a carbapenem. If there is a strong indication for penicillin or cephalopsorin consult with allergy and infectious disease
