Nursing Elites

1. 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: After a cardiac catheterization, the priority nursing care for a 3-year-old child is monitoring the site for bleeding. This is essential to promptly identify and address any signs of bleeding or hematoma formation, which are potential complications of the procedure. Encouraging early ambulation may be beneficial post-procedure but ensuring site integrity takes precedence. Restricting fluids until blood pressure stabilization is not a standard post-catheterization practice, as adequate hydration is crucial for recovery. Comparing the blood pressure of both lower extremities is not a priority immediate nursing action after a cardiac catheterization in a pediatric patient.

2. 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.

3. The nurse is caring for a 3-day-old girl with Down syndrome whose mother had no prenatal care. What is the priority nursing diagnosis?

• A. Imbalanced nutrition, less than body requirements related to the effects of hypotonia
• B. Deficient knowledge related to the presence of a genetic disorder
• C. Delayed growth and development related to cognitive impairment
• D. Impaired physical mobility related to poor muscle tone

Correct answer: A

Rationale: The priority nursing diagnosis for a newborn with Down syndrome is often related to feeding difficulties due to hypotonia, making imbalanced nutrition the primary concern. Hypotonia, or poor muscle tone, can lead to challenges with feeding and, subsequently, affect the baby's nutritional intake. While choices B, C, and D may also be concerns for a child with Down syndrome, addressing the immediate need for adequate nutrition takes precedence to ensure the infant's well-being and growth.

4. A young child has coarctation of the aorta. What does the nurse expect to identify when taking the child’s vital signs?

• A. A weak radial pulse
• B. An irregular heartbeat
• C. A bounding femoral pulse
• D. An elevated radial blood pressure

Correct answer: A

Rationale: In coarctation of the aorta, there is narrowing of the aorta leading to decreased blood flow distal to the constriction. This results in a weak or delayed femoral pulse and a relatively weaker radial pulse compared to the femoral pulse. An irregular heartbeat (choice B) is not a typical finding in coarctation of the aorta. A bounding femoral pulse (choice C) would not be expected due to the decreased blood flow beyond the constriction. An elevated radial blood pressure (choice D) is not a common characteristic of coarctation of the aorta; instead, blood pressure may be higher in the upper extremities compared to the lower extremities due to the constriction.

5. A child is diagnosed with atopic dermatitis. Which laboratory test would the nurse expect the child to undergo to provide additional evidence for this condition?

• A. Erythrocyte sedimentation rate
• B. Potassium hydroxide prep
• C. Wound culture
• D. Serum immunoglobulin E (IgE) level

Correct answer: D

Rationale: The correct answer is D: Serum immunoglobulin E (IgE) level. An elevated serum IgE level is commonly associated with atopic dermatitis, reflecting an allergic response. Choice A, erythrocyte sedimentation rate, is not typically used to diagnose atopic dermatitis. Choice B, potassium hydroxide prep, is used to identify fungal infections like ringworm, not for diagnosing atopic dermatitis. Choice C, wound culture, is performed to identify microorganisms in a wound, not to diagnose atopic dermatitis.
