Nursing interventions and care ( 7 Questions)
A client who has a history of penicillin allergy is prescribed cefazolin for a bacterial infection. The client asks the nurse why they can take cefazolin if they are allergic to penicillin. Which of the following responses should the nurse give?
"Cefazolin is a different type of antibiotic than penicillin, so you will not have an allergic reaction to it." This is an incorrect answer because cefazolin is not a different type of antibiotic than penicillin; they both belong to
the beta-lactam class of antibiotics. Therefore, there is still a possibility that the client could have an allergic reaction to cefazolin if they are allergic to penicillin.
"Cefazolin is a synthetic version of penicillin, so it does not contain any of the allergens that cause your reaction." This is an incorrect answer because cefazolin is not a synthetic version of penicillin; they are both derived from natural sources. Therefore, cefazolin could still contain some of the allergens that cause the client's reaction to penicillin.
Cefazolin is a similar type of antibiotic to penicillin, but it has a lower risk of causing an allergic reaction than penicillin. This is the correct answer because cefazolin belongs to the same class of antibiotics as penicillin, which are called beta-lactams. However, cefazolin is a first-generation cephalosporin, which has less cross-reactivity with penicillin than other cephalosporins. This means that clients who are allergic to penicillin have a lower chance of having an allergic reaction to cefazolin than to other beta-lactam antibiotics. The nurse should explain this to the client and monitor them for any signs of an allergic reaction.
"Cefazolin is a newer type of antibiotic than penicillin, so it has fewer side effects and less potential for causing an allergic reaction." This is an incorrect answer because cefazolin is not a newer type of antibiotic than penicillin; they were both discovered in the 1940s. Therefore, the age of the antibiotic does not determine its side effects or potential for causing an allergic reaction.
Answer: C. Cefazolin is a similar type of antibiotic to penicillin, but it has a lower risk of causing an allergic reaction than penicillin. This is the correct answer because cefazolin belongs to the same class of antibiotics as penicillin, which are called beta-lactams. However, cefazolin is a first-generation cephalosporin, which has less cross-reactivity with penicillin than other cephalosporins. This means that clients who are allergic to penicillin have a lower chance of having an allergic reaction to cefazolin than to other beta-lactam antibiotics. The nurse should explain this to the client and monitor them for any signs of an allergic reaction.
A) "Cefazolin is a different type of antibiotic than penicillin, so you will not have an allergic reaction to it." This is an incorrect answer because cefazolin is not a different type of antibiotic than penicillin; they both belong to
the beta-lactam class of antibiotics. Therefore, there is still a possibility that the client could have an allergic reaction to cefazolin if they are allergic to penicillin.
B) "Cefazolin is a synthetic version of penicillin, so it does not contain any of the allergens that cause your reaction." This is an incorrect answer because cefazolin is not a synthetic version of penicillin; they are both derived from natural sources. Therefore, cefazolin could still contain some of the allergens that cause the client's reaction to penicillin.
D) "Cefazolin is a newer type of antibiotic than penicillin, so it has fewer side effects and less potential for causing an allergic reaction." This is an incorrect answer because cefazolin is not a newer type of antibiotic than penicillin; they were both discovered in the 1940s.
