Nursing Elites

1. How is the diagnosis of Hirschsprung disease confirmed in a 1-month-old infant admitted to the pediatric unit?

• A. Colonoscopy
• B. Rectal biopsy
• C. Multiple saline enemas
• D. Fiberoptic nasoenteric tube

Correct answer: B

Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. It confirms the absence of ganglion cells in the affected bowel segment, which is characteristic of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for confirmation as it may not provide a definitive result. Multiple saline enemas (Choice C) are utilized in the treatment of meconium ileus, a complication of cystic fibrosis, and not in the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a diagnostic tool for Hirschsprung disease; it is commonly used for gastrointestinal decompression or feeding purposes but does not confirm the diagnosis.

2. When assessing the perfusion status of a 2-year-old child with possible shock, which of the following parameters would be LEAST reliable?

• A. distal capillary refill
• B. systolic blood pressure
• C. skin color and temperature
• D. presence of peripheral pulses

Correct answer: B

Rationale: The correct answer is B: systolic blood pressure. In young children, systolic blood pressure is the least reliable parameter for assessing perfusion status. Factors such as anxiety, crying, and fear can significantly affect blood pressure measurements, leading to inaccuracies. Distal capillary refill, skin color and temperature, and presence of peripheral pulses are more reliable indicators of perfusion status in pediatric patients. Distal capillary refill assesses peripheral perfusion, skin color, and temperature reflect tissue perfusion, and the presence of peripheral pulses indicates blood flow to the extremities. Therefore, when evaluating a 2-year-old child with possible shock, focusing on parameters other than systolic blood pressure is crucial for an accurate assessment of perfusion status.

3. The nurse is assessing a family to determine if they have access to adequate health care. Which statement accurately describes how certain families are affected by common barriers to health care?

• A. After a decade of escalation, the percentage of children living in low-income families has been on the decline since 2000.
• B. White, non-Hispanic children overall are more likely than African American and Hispanic children to be in very good or excellent health.
• C. The proportion of children between the ages of 6 and 18 who are overweight is decreasing, but a large increase is occurring in African American females.
• D. The overall health care plan of working families may improve access to specialty care but limit access to preventive services.

Correct answer: B

Rationale: Choice B is the correct answer because it accurately states that White, non-Hispanic children are more likely to be in very good or excellent health compared to African American and Hispanic children. This reflects a disparity in health outcomes among different racial groups. Choices A, C, and D are incorrect. Choice A is unrelated to the impact of common barriers to health care on families. Choice C talks about overweight children but does not address access to health care. Choice D discusses the impact of the overall health care plan on working families but does not specifically address the disparity in health status among different racial groups.

4. A 7-month-old girl is to be catheterized to obtain a sterile urine specimen. One of the infant’s parents expresses fear that this procedure may traumatize the baby psychologically. How should the nurse provide reassurance?

• A. The fear is justified and the nurse should obtain a “clean catch” specimen.
• B. Parents have a right to refuse the catheterization and the concerns are realistic.
• C. Although the concern is appropriate, the need for a sterile specimen is the priority.
• D. The procedure is uncomfortable, but there should not be a damaging long-term effect.

Correct answer: D

Rationale: While catheterization can be uncomfortable, it does not typically result in long-term psychological harm, and obtaining a sterile specimen is important for accurate diagnosis.

5. When developing the plan of care for a child with burns requiring fluid replacement therapy, what information would the nurse expect to include?

• A. Administration of colloid initially followed by a crystalloid
• B. Determination of fluid replacement based on the type of burn
• C. Administration of most of the volume during the first 8 hours
• D. Monitoring of hourly urine output to achieve less than 1 mL/kg/hr

Correct answer: C

Rationale: The correct answer is C. In fluid replacement therapy for burns, the majority of the volume should be administered within the first 8 hours to prevent shock and maintain perfusion. Choice A is incorrect because crystalloids are typically administered first in fluid resuscitation for burns. Choice B is incorrect as fluid replacement in burn patients is primarily determined by the extent of the burn injury rather than the type of burn. Choice D is incorrect as the goal for hourly urine output in burn patients is generally higher, aiming for 1-2 mL/kg/hr in children to ensure adequate renal perfusion and prevent dehydration.
