The following is/are true about 4C Men B protein vaccine (Bexsero®):

Correct Answer: D

Rationale: The correct answer is option D: "Is licensed for use from 2 months of age." This is the correct answer because the 4C Men B protein vaccine (Bexsero®) is indeed licensed for use in infants as young as 2 months of age, as per the recommendations from regulatory agencies and medical authorities. Option A: "Bexsero® may protect up to 98% of circulating Men B strains in England and Wales" is incorrect. While Bexsero® is effective against many strains of Men B, the specific percentage can vary based on geographical location and circulating strains. Option B: "Bexsero® may also protect against infection by other capsular groups of meningococcus" is incorrect. Bexsero® primarily targets Men B strains and does not provide broad protection against other capsular groups of meningococcus. Option C: "Is currently recommended for all household contacts of an index case of invasive group B meningococcal disease" is incorrect. While close contacts of individuals with meningococcal disease may be recommended to receive prophylactic treatment, the specific recommendation for Bexsero® may vary depending on the situation and guidelines in place. Educational Context: Understanding the specifics of the 4C Men B protein vaccine (Bexsero®) is crucial for healthcare providers, especially those preparing for exams like the NCLEX. Knowing the age indication for the vaccine, its efficacy, and its limitations can help healthcare professionals make informed decisions when it comes to preventing and managing meningococcal disease in clinical practice.

Correct Answer: B

Rationale: The correct answer is option B) People with chronic heart disease should receive pneumococcal vaccines. Pneumococcal vaccines are especially important for individuals with underlying health conditions that put them at higher risk for developing serious complications from pneumococcal infections, such as chronic heart disease. These individuals have weakened immune systems and are more susceptible to severe illness or even death from pneumococcal diseases. Option A) is incorrect because children over 2 years of age who are at risk should receive a dose of PPV but not in addition to primary PCV doses. Option C) is incorrect because diabetics controlled by diet do not have the same level of immune compromise as those on medications such as insulin. Option D) is incorrect because people with cochlear implants do not specifically require pneumococcal vaccines unless they have other underlying health conditions that warrant it. In an educational context, it is crucial for healthcare providers to understand the specific populations that require pneumococcal vaccines to provide appropriate care and prevent the spread of infectious diseases. Understanding the rationale behind vaccine recommendations helps in improving patient outcomes and reducing the burden of preventable diseases in vulnerable populations.

Correct Answer: A

Rationale: The correct answer is A because an internal disaster refers to an emergency situation that directly impacts the facility itself. A tornado touching down on the healthcare facility falls under this category as it affects the facility's operations and infrastructure. B is incorrect because a severe cyclone destroying nearby homes is an external disaster, not directly impacting the facility itself. C is incorrect as a massive train accident bringing victims to the facility is an external disaster affecting the community, not an internal disaster for the facility. D is incorrect as an act of bioterrorism in a nearby factory is also an external disaster unless it directly affects the healthcare facility.

Correct Answer: B

Rationale: The correct answer is B: System variance. This is because the lack of necessary supplies and equipment is a systemic issue related to the healthcare system's operations and resource management. It reflects a deviation from the standard processes and protocols in place for ensuring patient safety. A: Sentinel event refers to a serious adverse event that results in patient harm. C: Adverse effect typically refers to a negative outcome resulting from a specific treatment or intervention. D: Provider variance relates to variations in individual provider performance. Therefore, the lack of necessary supplies and equipment is best categorized as a system variance as it points to a broader issue within the healthcare system rather than individual actions or specific patient outcomes.

Correct Answer: D

Rationale: Correct Answer: D - Bar coded client identification bands to insure proper identification Rationale: 1. Bar coded identification bands provide a secure way of identifying clients accurately. 2. This helps prevent unauthorized access and ensures proper identification of individuals. 3. It enhances security measures and helps in tracking patients within the facility. 4. It is important for maintaining patient safety and confidentiality. Summary: A: Training nurses may be helpful, but it is not as effective as implementing proper identification measures. B: Clerical staff may not be directly involved in security response and may not be best suited for this role. C: Restricting visitors is important for security, but it does not address the issue of proper identification.
