A nurse is preparing to administer recommended immunizations to an 11-year-old child who is up-to-date with current immunizations. Which of the following immunizations should the nurse plan to administer?

Choice A rationale:
This statement reflects an accurate understanding of varicella (chickenpox) transmission and infection control. The lesions of varicella contain the virus and are contagious until they have crusted over. Allowing the child to go to the playroom only after the lesions have crusted helps prevent the spread of the virus to other individuals.
Choice B rationale:
This statement is incorrect because waiting for the crusts to fall off the lesions before bathing the child is not necessary. In fact, keeping the lesions clean and maintaining proper hygiene through gentle bathing can help prevent secondary bacterial infections.
Choice C rationale:
This statement is incorrect because bedrest for 3 days is not necessary for a child with varicella. While it's important to minimize contact with others during the contagious phase, physical activity can be gradually resumed as long as the lesions have crusted to prevent transmission.
Choice D rationale:
This statement is incorrect. Once a person has had chickenpox (varicella), they develop immunity to the virus and do not need to wear a mask when visiting someone with active varicella. This is because they are already immune to the virus due to their prior infection.

Choice A rationale:
Decrease daily oral fluid intake. Rationale: This choice is not appropriate for a client experiencing a vaso-occlusive crisis in sickle cell anemia. In this crisis, there is a risk of dehydration due to increased fluid loss, and decreasing oral fluid intake would exacerbate this issue. Adequate hydration is important to prevent further sickling of red blood cells and maintain organ perfusion.
Choice B rationale:
Maintain bed rest to prevent hypoxemia. Rationale: This is the correct choice. During a vaso-occlusive crisis in sickle cell anemia, blood flow to certain tissues is restricted, leading to tissue hypoxia and pain. Bed rest is recommended to reduce metabolic demands and oxygen consumption, helping to prevent further tissue damage and improve oxygenation. It also reduces the risk of complications such as thrombosis and respiratory compromise.
Choice C rationale:
Apply cold compresses to painful joints. Rationale: Applying cold compresses is not a recommended intervention for vaso-occlusive crisis in sickle cell anemia. Cold can exacerbate vasoconstriction and further compromise blood flow to the affected tissues. Warm compresses or warm baths might be more appropriate to promote vasodilation and alleviate pain.
Choice D rationale:
Administer meperidine to eliminate a fever. Rationale: Administering meperidine solely to eliminate a fever is not the primary focus of care for a vaso-occlusive crisis. The priority is to manage pain and improve tissue perfusion. Meperidine is an opioid analgesic that can be used to manage severe pain associated with sickle cell crises, but it should be given with caution due to the risk of respiratory depression and the potential for addiction.
