Nursing Elites

1. 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: The correct answer is A: nondisjunction. Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division leading to an extra copy of chromosome 21. This additional genetic material alters the course of development and causes the characteristics associated with Down syndrome. Choices B, C, and D are incorrect. X-linked recessive inheritance refers to genetic disorders carried on the X chromosome, genomic imprinting involves gene expression based on parental origin, and autosomal dominant inheritance relates to disorders caused by a dominant gene on one of the non-sex chromosomes. In the case of trisomy 21, the cause is specifically related to the error in chromosome division, making nondisjunction the most appropriate answer.

2. Parents of a sick infant talk with a nurse about their baby. One parent says, “I am so upset; I didn’t realize our baby was ill.” What major indication of illness in an infant should the nurse explain to the parent?

• A. Grunting respirations
• B. Excessive perspiration
• C. Longer periods of sleep
• D. Crying immediately after feedings

Correct answer: C

Rationale: The correct answer is C. Longer periods of sleep than usual can be a sign of illness in infants. When an infant sleeps more than usual, it can indicate that the baby is conserving energy due to an underlying condition. Grunting respirations (choice A) can be a sign of respiratory distress, not just an indication of illness. Excessive perspiration (choice B) can occur due to various reasons and is not a specific major indication of illness. Crying immediately after feedings (choice D) is a common behavior in infants and not necessarily a major indication of illness.

3. A child with sickle cell anemia develops severe chest pain, fever, a cough, and dyspnea. The nurse's first action is to

• A. administer 100% oxygen to relieve hypoxia
• B. administer pain medication to relieve symptoms
• C. notify the practitioner because chest syndrome is suspected
• D. notify the practitioner because the child may be having a stroke

Correct answer: C

Rationale: In a child with sickle cell anemia experiencing severe chest pain, fever, cough, and dyspnea, the priority action is to suspect acute chest syndrome, a life-threatening complication. The nurse's first action should be to notify the practitioner for immediate evaluation and intervention. Administering 100% oxygen (Choice A) may be necessary later but is not the initial priority. Administering pain medication (Choice B) should not precede notifying the practitioner, as addressing the underlying cause is crucial. The symptoms described are more indicative of acute chest syndrome than a stroke, so notifying the practitioner for chest syndrome (Choice C) takes precedence over suspecting a stroke (Choice D).

4. The healthcare provider is assessing the 'resilience' of a 16-year-old boy. Which exemplifies an external protective factor that may help promote resilience 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 in individuals, especially in adolescents. This support system provides a sense of security, stability, and emotional connection, which can help the teenager navigate challenges and setbacks. Choices A, B, and D allude to internal factors related to personal decision-making, self-awareness, and goal management, which are important but do not directly represent external protective factors involving external relationships or resources.

5. The nurse is assessing a child with a possible fracture. What would the nurse identify as the most reliable indicator?

• A. Lack of spontaneous movement
• B. Point tenderness
• C. Bruising
• D. Inability to bear weight

Correct answer: B

Rationale: Point tenderness is the most reliable indicator of a possible fracture in a child. It is a localized tenderness experienced when pressure is applied to a specific area, suggesting a potential fracture. This tenderness is considered more specific to a fracture than other symptoms such as lack of spontaneous movement, bruising, or inability to bear weight. Lack of spontaneous movement and inability to bear weight can be present in various musculoskeletal injuries, while bruising may not always be immediate or specific to a fracture.
