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. A 1-month-old girl with low-set ears and severe hypotonia has been diagnosed with trisomy 18. Which nursing diagnosis would the nurse identify as most likely?

• A. Interrupted family process related to the child's diagnosis
• B. Deficient knowledge related to the genetic disorder
• C. Grieving related to the child's poor prognosis
• D. Ineffective coping related to the stress of providing care

Correct answer: C

Rationale: The most likely nursing diagnosis for a 1-month-old girl with trisomy 18, characterized by low-set ears and severe hypotonia, is 'Grieving related to the child's poor prognosis.' Trisomy 18 is associated with a poor prognosis, and families often experience grief as they come to terms with the challenges and uncertainties associated with the condition. 'Interrupted family process' may not be as relevant since the primary focus is on the child's condition. 'Deficient knowledge related to the genetic disorder' could be important but may not be the most likely initial concern, as emotional support for the family is crucial at this point. 'Ineffective coping related to the stress of providing care' is a broad diagnosis that does not specifically address the emotional response to the child's prognosis, which is the primary concern in this case.

3. A 3-year-old child is admitted to the hospital with a diagnosis of Kawasaki disease. What is the priority nursing intervention?

• A. Administering IV immunoglobulin
• B. Monitoring for coronary artery aneurysms
• C. Encouraging fluid intake
• D. Providing nutritional support

Correct answer: B

Rationale: The priority nursing intervention for a 3-year-old child with Kawasaki disease is monitoring for coronary artery aneurysms. Kawasaki disease can lead to the development of coronary artery aneurysms, which are one of the most serious complications of the disease. Early detection and monitoring of coronary artery changes are essential for prompt intervention and prevention of adverse outcomes. Administering IV immunoglobulin is an important treatment for Kawasaki disease, but monitoring for coronary artery aneurysms takes precedence as it directly impacts the child's long-term prognosis. Encouraging fluid intake and providing nutritional support are important aspects of care but are not the priority when compared to monitoring for potential life-threatening complications.

4. A child with a diagnosis of diabetes mellitus is being discharged from the hospital. What is important for the nurse to include in the discharge teaching?

• A. Monitor blood glucose levels daily
• B. Administer insulin based on blood glucose levels
• C. Recognize signs of hypoglycemia
• D. Follow a specific meal plan

Correct answer: D

Rationale: For a child with diabetes mellitus, following a specific meal plan is crucial for managing blood glucose levels effectively. This helps in maintaining stable blood sugar levels and preventing complications associated with the condition. Monitoring blood glucose levels daily and recognizing signs of hypoglycemia are also important aspects of managing diabetes; however, adherence to a specific meal plan plays a fundamental role in overall diabetes care. Administering insulin based on blood glucose levels alone is not recommended without a specific plan provided by healthcare providers.

5. When administering IV fluids to a dehydrated infant, what intervention is most important at this time?

• A. Continuing the prescribed flow rate
• B. Monitoring the intravenous drop rate
• C. Calculating the total necessary intake
• D. Maintaining the fluid at body temperature

Correct answer: B

Rationale: Monitoring the intravenous drop rate is crucial when administering IV fluids to ensure that the correct amount of fluids is delivered to the dehydrated infant. Choice A assumes the initial rate is correct without ongoing assessment. Choice C, while important, does not address the immediate need for monitoring the infusion rate. Choice D, maintaining the fluid at body temperature, is essential for comfort but is not as critical as ensuring the correct fluid delivery rate. By monitoring the intravenous drop rate, healthcare providers can adjust the flow as needed to prevent overhydration or underhydration, helping to manage the infant's fluid balance effectively.
