Nursing Elites

1. When describing urticaria, what would an instructor include?

• A. It is a type IV hypersensitivity reaction.
• B. Histamine release leads to vasodilation.
• C. Wheals appear first followed by erythema.
• D. The nonpruritic rash blanches with pressure.

Correct answer: B

Rationale: The correct answer is B. Urticaria is a type I hypersensitivity reaction where histamine release leads to vasodilation and the formation of characteristic wheals. Choice A is incorrect as urticaria is associated with type I hypersensitivity, not type IV. Choice C is incorrect because in urticaria, erythema typically appears before the development of wheals. Choice D is incorrect as urticaria is typically pruritic and does not blanch with pressure.

2. Why is the infant scheduled to receive the intramuscular polio vaccine instead of the oral vaccine, as asked by the parents?

• A. The American Academy of Pediatrics recommends the intramuscular vaccine because it is safer.
• B. Both vaccines produce the same results and are equally safe, according to consensus.
• C. The intramuscular vaccine is preferred over the oral vaccine due to cost considerations, unless contraindicated.
• D. The U.S. Centers for Disease Control and Prevention recommends the intramuscular vaccine unless the infant or a family member is immunocompromised.

Correct answer: A

Rationale: The American Academy of Pediatrics recommends the intramuscular polio vaccine over the oral vaccine due to its superior safety profile. Intramuscular administration ensures better immunogenicity and protection against poliovirus. Choice B is incorrect as the intramuscular vaccine is preferred for safety reasons. Choice C is incorrect because the recommendation is based on safety, not cost. Choice D is incorrect as the CDC recommendation is not solely based on immunocompromised status but rather on the overall safety and efficacy of the vaccine.

3. After a cardiac catheterization, what is the priority nursing care for a 3-year-old child?

• A. Encouraging early ambulation
• B. Monitoring the site for bleeding
• C. Restricting fluids until the blood pressure is stabilized
• D. Comparing the blood pressure of both lower extremities

Correct answer: B

Rationale: The priority nursing care after a cardiac catheterization in a 3-year-old is to monitor the site for bleeding. This is essential to promptly detect and manage any potential complications, such as hematoma or hemorrhage. Encouraging early ambulation, as mentioned in choice A, may not be safe immediately post-procedure and should be guided by the healthcare provider's instructions. Restricting fluids until blood pressure is stabilized, as in choice C, is not typically necessary after a cardiac catheterization. Comparing blood pressure in both lower extremities, as in choice D, is not the priority immediate nursing care following this procedure.

4. A nurse is providing care to a child diagnosed with sickle cell anemia. What is the priority nursing intervention?

• A. Administering pain medication
• B. Ensuring adequate hydration
• C. Providing nutritional support
• D. Monitoring vital signs

Correct answer: A

Rationale: In sickle cell anemia, pain management is a priority due to vaso-occlusive crises that cause severe pain. Administering pain medication helps alleviate discomfort and improve the child's quality of life. Ensuring adequate hydration, although important, is secondary to addressing the immediate pain issue. Providing nutritional support is beneficial for overall health but does not address the acute pain experienced. Monitoring vital signs is essential but not the immediate priority when managing pain in sickle cell anemia.

5. The parents of a 6-week-old infant who was born without an immune system ask a nurse why their baby is still so healthy. How should the nurse reply?

• A. Exposure to pathogens during this time can be limited.
• B. Some antibodies are produced by the infant’s colonic bacteria.
• C. Antibodies are passively received from the mother through the placenta and breast milk.
• D. Fewer antibodies are produced by the fetal thymus during the eighth and ninth months of gestation.

Correct answer: C

Rationale: The correct answer is C. Infants receive passive immunity through antibodies from the mother during pregnancy and breastfeeding, which protect them initially. Choice A is incorrect because a 6-week-old infant born without an immune system would not be able to limit exposure to pathogens effectively. Choice B is incorrect as antibodies produced by colonic bacteria are not a significant source of immunity in infants. Choice D is incorrect as the fetal thymus primarily plays a role in T cell development rather than antibody production during gestation.
