Adverse reactions to anthrax vaccine can include:

Correct Answer: A

Rationale: In this question regarding adverse reactions to the anthrax vaccine, the correct answer is A) Swelling at the injection site. This reaction is a common local adverse effect of the anthrax vaccine. Swelling at the injection site is expected due to the body's immune response to the vaccine components. It is usually mild and self-limiting. Option B) Urticaria, and option C) Regional lymphadenopathy are less common adverse reactions to the anthrax vaccine. Urticaria refers to hives or a rash on the skin, which can occur as a hypersensitivity reaction. Regional lymphadenopathy is the swelling of lymph nodes near the injection site, which can also be a response to the vaccine components. Option D) Generally, a higher risk of a reaction after subsequent doses if there was a reaction to the first dose is incorrect. Adverse reactions to the first dose of a vaccine do not necessarily mean an increased risk of reaction to subsequent doses. Each dose of the vaccine is administered independently based on the individual's health status and previous reactions. Understanding adverse reactions to vaccines is crucial in nursing practice, especially in infection control. Nurses need to recognize and manage these reactions effectively to ensure patient safety and promote compliance with vaccination protocols. Educating patients about common and rare adverse reactions can help alleviate fears and misunderstandings about vaccines, ultimately enhancing public health outcomes.

Correct Answer: B

Rationale: The correct answer is B) They should have 1 further dose of hep B vaccine. This is because an anti-HBs level of 10 mIU/mL is considered inadequate for long-term protection against hepatitis B. A level below 10 mIU/mL indicates a non-protective response to the vaccine. By administering one further dose of the hepatitis B vaccine, the healthcare worker has a better chance of achieving a protective anti-HBs level. Option A is incorrect because an anti-HBs level of 10 mIU/mL is not considered satisfactory protection. Option C is incorrect as a single further dose is recommended rather than a full course of vaccination. Option D is incorrect because a single booster dose after 5 years is typically recommended for those with adequate initial response and not for individuals with an inadequate immune response like in this case. In an educational context, it is crucial for healthcare workers to understand the significance of serologic testing post-vaccination. This case highlights the importance of monitoring antibody levels to ensure adequate protection against hepatitis B. It also emphasizes the need for timely interventions, such as additional doses of the vaccine, to boost immunity when necessary. Healthcare professionals must stay informed about vaccination protocols to safeguard both themselves and their patients from infectious diseases.

Correct Answer: A

Rationale: The correct answer is A) Pain and swelling at the injection site. Inactivated flu vaccines are typically well-tolerated, with the most common adverse reactions being localized to the injection site. Pain and swelling at the injection site are common reactions that usually resolve on their own within a few days. Option B) High grade fever is less likely to be an adverse reaction to the inactivated flu vaccine. While low-grade fevers can occur as a response to the vaccine, a high-grade fever is not a typical adverse reaction. Option C) Myalgia (muscle pain) can occur as a systemic reaction to the flu vaccine but is less common than pain and swelling at the injection site. Option D) Shivering is not a typical adverse reaction to the inactivated flu vaccine. Shivering may occur in response to a fever, but it is not a direct result of the vaccine. In an educational context, it is important for healthcare providers to be knowledgeable about possible adverse reactions to vaccines to provide accurate information to patients. Understanding the common and uncommon reactions to vaccines can help in distinguishing normal side effects from potential allergic reactions, ensuring patient safety and comfort.

Correct Answer: A

Rationale: In the context of infection control nursing, understanding the characteristics of meningococci is crucial for preventing the spread of meningococcal disease. The correct answer, Option A, states that meningococci are most often harmless commensals colonizing the nasopharynx. This is important to know because many individuals can carry these bacteria without showing any signs of illness. This colonization is considered normal and asymptomatic in most cases. Option B is incorrect because while it is true that a significant proportion of adolescents can carry meningococci without symptoms, it is not accurate to say that about a quarter of adolescents carry them. This overestimation could lead to unnecessary alarm or interventions. Option C is incorrect because meningococci are primarily transmitted through respiratory secretions, such as droplets from the nose or mouth of an infected person, rather than through aerosol transmission. Understanding the mode of transmission is essential for implementing appropriate infection control measures. Option D is incorrect because meningococci are typically spread through close contact, such as respiratory droplets or direct contact with respiratory secretions, rather than being transmitted with minimal contact. This distinction is crucial for healthcare providers to effectively implement infection prevention protocols. Educationally, this question highlights the importance of accurate knowledge about the characteristics and transmission of meningococci in the context of infection control nursing. It underscores the need for healthcare professionals to understand the nuanced details of pathogen behavior to implement targeted prevention strategies effectively.

Correct Answer: B

Rationale: Infection control in nursing is crucial for preventing the spread of diseases, especially in vulnerable populations like pregnant women and newborns. Pertussis, or whooping cough, is a highly contagious respiratory disease that can be severe for infants. Prenatal pertussis vaccination is recommended to provide passive immunity to newborns until they are old enough to be vaccinated themselves. Option B, "Vaccine should be offered in every pregnancy," is correct because giving the vaccine during each pregnancy maximizes protection for each newborn. This strategy ensures that maternal antibodies are transferred to the fetus, offering protection during the vulnerable early months of life. Option A, "Vaccination should be offered starting from 26 weeks of gestation," is incorrect because the recommendation is to administer the vaccine between 27-36 weeks of gestation to optimize transfer of antibodies to the fetus. Option C, "It should not be offered after 32 weeks of pregnancy as it is unlikely to offer any protection," is incorrect because vaccination can still provide some protection even if given later in pregnancy, although earlier administration is preferred. Option D, "Both Boostrix and Repevax are suitable for use in the prenatal program," is incorrect because only Boostrix is recommended for prenatal use, not Repevax. Educationally, understanding the timing and choice of vaccines in prenatal care is essential for nurses to provide evidence-based care to pregnant women. By knowing the correct recommendations for pertussis vaccination, nurses can help protect both the mother and her newborn from this preventable disease.
