After Hepatitis B vaccination, what is a typical nursing consideration?

• A. Avoid giving fluids for 24 hours
• B. Monitor for fever or redness at the injection site and observe for rare allergic reactions
• C. Administer analgesics only if patient requests
• D. Do not document any reaction

Answer: (B)

Monitoring for adverse reactions after vaccination is essential. After a Hepatitis B vaccine, most issues are local—redness, swelling, and soreness at the injection site—and a mild fever can occur. The nurse should inspect the injection site and monitor temperature and other vital signs, while educating the patient to report systemic signs such as hives, facial or throat swelling, or breathing trouble, which would indicate a rare allergic reaction. Because serious reactions are uncommon but possible, an observation period after administration helps catch any immediate anaphylaxis, and any reaction should be documented. Analgesics or antipyretics may be used to relieve symptoms if they arise, following protocol.
