Question

Before administering an annual influenza vaccination, the nurse should question the client about past allergic reaction to: A. Eggs B. Milk C. Shellfish D. Nuts

Short answer

Short Answer: A nurse should question a client about a potential egg allergy before administering an annual flu vaccination. This is because the traditional manufacturing process of flu vaccines involves the use of chicken eggs which may result in trace amounts of egg proteins being present in the vaccine, potentially triggering allergic reactions in individuals with an egg allergy.

Step-by-step solution

Identify the correct allergen

Before administering an annual influenza vaccination, it is essential to know the client's history of food allergies. In this case, the correct allergen to question the client about is eggs.

Explain the importance of egg allergy in influenza vaccinations

The reason it is crucial to question a client about egg allergy before administering the flu vaccine is that the traditional manufacturing process of flu vaccines involves the use of chicken eggs. The virus is grown in fertilized chicken eggs where it multiplies, and then it is harvested, inactivated, and purified to produce the vaccine. Consequently, some vaccines may contain trace amounts of egg proteins, which might trigger allergic reactions in people with an egg allergy.

Present the correct answer

Given this information, the correct answer to this question is: A. Eggs

Key concepts

Egg Allergy and Immunizations

Understanding and meticulously addressing concerns with egg allergies is pivotal in the context of vaccinations. Immunizations, such as the traditional influenza vaccine, often utilize egg-based cultures during production; this means the vaccines could contain trace amounts of egg proteins. While exposure to these tiny amounts typically does not trigger severe reactions in individuals with egg allergies, it's a point of caution.

Healthcare professionals must ascertain a patient's allergy history, explicitly focusing on egg allergies, before administering certain vaccines. However, it's worth noting that advancements in vaccine technology have led to the development of egg-free flu vaccines, suitable for individuals with severe egg allergies. If a patient does have an egg allergy, the provider can take precautionary steps, including choosing an egg-free vaccine or administering a vaccine under medical supervision for patients with a history of severe reactions.

Flu Vaccine Contraindications

When it comes to the influenza vaccination, there are specific contraindications that health professionals must be aware of to prevent adverse reactions or worsening of a patient's condition. Besides egg allergy, a known severe allergic reaction to a flu vaccine in the past or to any of its components is a red flag.

Other contraindications include a history of Guillain-Barré Syndrome within six weeks following a previous flu vaccination. Caution is also advised in individuals who are feeling unwell, although those with mild illness can still be vaccinated. Vital considerations also include the vaccine’s appropriateness for certain age groups, and it is important to select the correct vaccination formulation accordingly. Patient education on potential mild side-effects such as soreness at the injection site or low-grade fever is also crucial for informed consent.

Nursing Considerations for Vaccinations

Nurses play a critical role in the vaccination process, and there are several considerations that must be taken into account to ensure the safety and effectiveness of immunization practices. First, nurses should review a patient’s medical history for contraindications and allergy profile, as mentioned earlier regarding egg allergies and influenza vaccinations.

Also, they need to assess the patient’s current health status, including any acute illness or fever that could impact the timing of the vaccination. Patient education is another cornerstone; this involves explaining the benefits and possible side effects of the vaccine, ensuring that patients can make an informed decision. Prioritizing aseptic technique to prevent infection and correct storage and handling of vaccines are also essential nursing practices. Post-vaccination, monitoring the patient for adverse reactions and providing proper documentation are fundamental tasks that nurses are responsible for. These considerations ensure patient safety and optimize the outcomes of vaccination programs.
