Penicillin Quiz: Can You Spot The Allergy Risk?

1. Which finding would contraindicate penicillin use in a patient with a history of penicillin allergy?

Mild rash without systemic symptoms

Previous urticaria with penicillin exposure

Family history of penicillin allergy

Intolerance to lactose in formulation

2. A patient reports a 'penicillin allergy' from childhood but cannot describe the reaction. What is the best nursing action?

Avoid all penicillins and beta-lactams

Obtain detailed allergy history and consider allergy evaluation

Administer penicillin under close monitoring

Assume the allergy is no longer relevant

Submit

4. Which statement best describes the risk of anaphylaxis in penicillin-allergic patients?

Risk is identical regardless of allergy type or timing

Immediate reactions carry higher anaphylaxis risk than delayed reactions

Anaphylaxis only occurs with intravenous administration

Previous rash eliminates anaphylaxis risk

5. True or False: Penicillin G is the preferred agent for treating syphilis in all patient populations.

True

False

Submit

7. Penicillin allergy skin testing is most reliable for detecting which type of hypersensitivity?

Type II cytotoxic reactions

Type I IgE-mediated reactions

Type III immune complex reactions

Type IV delayed-type reactions

8. A patient with a documented penicillin allergy needs a beta-lactam antibiotic. Which is the safest choice?

Cephalexin

Aztreonam

Cefotaxime

Cefazolin

9. True or False: Penicillins are safe to use during pregnancy across all trimesters.

True

False

10. Extended-spectrum penicillins are effective against which organism that ampicillin cannot cover?

Streptococcus pneumoniae

Pseudomonas aeruginosa

Staphylococcus aureus

Escherichia coli

11. What is the primary mechanism of action of penicillins?

Inhibit bacterial cell wall synthesis

Disrupt bacterial protein synthesis

Inhibit bacterial DNA replication

Interfere with bacterial metabolism

Submit

13. True or False: Patients with mononucleosis can safely receive ampicillin without risk of rash.

True

False

14. A patient develops fever and joint pain five days after starting penicillin. This suggests which reaction?

Immediate hypersensitivity

Serum sickness

Stevens-Johnson syndrome

Toxic epidermal necrolysis

15. Which penicillin-type antibiotic has the broadest spectrum of activity?

True

False

17. A patient with a documented penicillin allergy requires antibiotic therapy. Which alternative is safest?

First-generation cephalosporin

Fluoroquinolone or macrolide

Third-generation cephalosporin

Amoxicillin-clavulanate

18. Anaphylaxis after penicillin administration is mediated by which immunoglobulin?

IgG

IgE

IgM

IgA

19. Which statement about penicillin allergy cross-reactivity is accurate?

All beta-lactams cause cross-reactions in penicillin-allergic patients

Cephalosporins have minimal cross-reactivity with penicillins

Cross-reactivity risk depends on R-group similarity and patient history

Macrolides are contraindicated in penicillin-allergic patients

20. A patient reports a rash after taking amoxicillin. Which type of reaction is most likely?

IgE-mediated immediate hypersensitivity

Delayed-type hypersensitivity reaction

Cytotoxic reaction

Immune complex reaction
