Nursing Elites

1. 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.

2. The nurse is assessing the 'resilience' of a 16-year-old boy. Which exemplifies an external protective factor that may help to promote resiliency in this child?

• A. His ability to take control of his own decisions
• B. His ability to accept his own limitations
• C. His caring relationship with members of his family
• D. His knowledge of when to continue or stop with goal achievement

Correct answer: C

Rationale: A caring relationship with family members is an external protective factor that promotes resilience. It provides emotional support, stability, and a sense of belonging, which are crucial elements in building resilience. Choices A, B, and D are more related to internal factors and individual traits rather than external factors like family relationships, which play a significant role in promoting resilience. Taking control of decisions, accepting limitations, and knowing when to stop or continue with goals are internal factors that contribute to personal resilience but do not directly represent external protective factors like family relationships.

3. The nurse is implementing care for a school-age child admitted to the pediatric intensive care unit with diabetic ketoacidosis (DKA). Which prescribed intervention should the nurse implement first?

• A. Begin 0.9% saline solution intravenously as prescribed
• B. Administer regular insulin intravenously as prescribed
• C. Place child on a cardiac monitor
• D. Place child on a pulse oximetry monitor

Correct answer: A

Rationale: Initiating intravenous saline solution is the initial priority in managing diabetic ketoacidosis to address dehydration and electrolyte imbalances. Administering insulin without addressing dehydration first can lead to potential complications. While monitoring cardiac status and oxygen saturation are important, addressing the fluid and electrolyte imbalances takes precedence in the management of DKA.

4. When teaching a class about trisomy 21, the instructor would identify the cause of this disorder as:

• A. nondisjunction.
• B. X-linked recessive inheritance.
• C. genomic imprinting.
• D. autosomal dominant inheritance.

Correct answer: A

Rationale: Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division that leads to the presence of an extra chromosome 21. This additional chromosome alters the normal genetic makeup, resulting in the characteristics associated with Down syndrome. Therefore, the correct answer is nondisjunction (Choice A). Choices B, C, and D are incorrect because Trisomy 21 is not caused by X-linked recessive inheritance, genomic imprinting, or autosomal dominant inheritance. Understanding the specific genetic mechanism involved in Trisomy 21 is crucial for grasping the basis of this chromosomal disorder.

5. The mother of a 5-year-old boy with a myelomeningocele, who has developed a sensitivity to latex, is being taught by the nurse. Which response from his mother indicates a need for further teaching?

• A. He needs to wear a medical alert identification.
• B. I will need to inform his caregivers about his latex sensitivity.
• C. A product's label always indicates whether it is latex-free.
• D. He must avoid any contact with latex.

Correct answer: C

Rationale: Choice C, 'A product's label always indicates whether it is latex-free,' indicates a need for further teaching. Not all products are clearly labeled as latex-free; therefore, it is essential to verify with manufacturers and healthcare providers. Choices A, B, and D demonstrate appropriate understanding of managing latex sensitivity in the child. Wearing a medical alert identification (Choice A), informing caregivers (Choice B), and avoiding all contact with latex (Choice D) are all important aspects of managing a child's latex sensitivity.
