Nursing Elites

1. A healthcare professional is reviewing the laboratory report of a child with tetralogy of Fallot that indicates an elevated RBC count. What does the professional identify as the cause of the polycythemia?

• A. Low tissue oxygen needs
• B. Tissue oxygen needs
• C. Diminished iron level
• D. Hypertrophic cardiac muscle

Correct answer: B

Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs as the body's response to chronic hypoxia by increasing RBC production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect, the heart's structure causes reduced oxygen levels in the blood. This chronic hypoxia stimulates the bone marrow to produce more red blood cells, leading to an elevated RBC count. Choice A is incorrect as low blood pressure is not directly related to polycythemia in this context. Choice C, diminished iron level, is not the cause of polycythemia in tetralogy of Fallot. Choice D, hypertrophic cardiac muscle, is not the primary cause of the elevated RBC count in this case.

2. A parent calls the outpatient clinic requesting information about the appropriate dose of acetaminophen for a 16-month-old child who has signs of an upper respiratory tract infection and fever. The directions on the bottle of acetaminophen elixir are 120 mg every 4 hours when needed. At the toddler’s 15-month visit, the health care provider prescribed 150 mg. What is the nurse’s best response to the parent?

• A. “The dose is close enough, and it doesn’t really matter which one is given.”
• B. “From your description, the medications are not necessary. They should be avoided at this age.”
• C. “It is appropriate to use dosages based on age. Children typically have weights consistent for their age groups.”
• D. “The prescribed dose of the drug was based on weight, and this is a more accurate way of determining a therapeutic dose.”

Correct answer: D

Rationale: The most accurate way to determine a therapeutic dose for children is based on their weight rather than age. Weight-based dosing helps ensure that the child receives the appropriate amount of medication for their body size, which is crucial for safety and effectiveness. Age-based dosing can lead to underdosing or overdosing, as children of the same age can have significantly different weights. Choice A is incorrect because even small variations in dosages can have significant effects on a child's health. Choice B is incorrect as acetaminophen can be appropriate when used correctly for fever management in children. Choice C is incorrect as children's weights can vary greatly within the same age group, making weight-based dosing more precise and individualized.

3. What definitive diagnostic procedure does the nurse expect to be used to confirm the diagnosis of Hirschsprung disease in a 1-month-old infant?

• 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. This procedure reveals the absence of ganglion cells in the affected bowel segment, which is a hallmark of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for diagnosing Hirschsprung disease due to the risk of not accurately reaching the affected segment. Multiple saline enemas (Choice C) are not used to confirm the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a standard diagnostic procedure for Hirschsprung disease and does not provide the necessary information to confirm the absence of ganglion cells in the affected bowel segment.

4. A nurse is developing a teaching plan for an 8-year-old child who has recently been diagnosed with type 1 diabetes. What developmental characteristic of a child this age should the nurse consider?

• A. Child is in the concrete operational stage of cognition.
• B. Child’s dependence on peer influence is increasing.
• C. Child will welcome opportunities for participation in self-care.
• D. Child’s developmental stage involves achieving a sense of autonomy.

Correct answer: C

Rationale: The correct answer is C. At the age of 8, children are typically in the stage of industry vs. inferiority according to Erikson's psychosocial theory. This stage is characterized by a desire to engage in productive activities and take on responsibilities. Thus, the child will likely welcome opportunities for participation in self-care related to their diabetes management. Choices A, B, and D are incorrect. Choice A is inaccurate as children at this age are usually in the concrete operational stage of cognitive development, not abstract. Choice B is incorrect because while peer influence is significant, it has not reached its peak at this age. Choice D is wrong as achieving a sense of identity is a developmental task more commonly associated with adolescence, not 8-year-old children.

5. A 6-month-old infant is admitted with a diagnosis of respiratory syncytial virus (RSV). What should the nurse include in the care plan?

• A. Providing small, frequent feedings
• B. Administering antibiotics
• C. Maintaining strict isolation
• D. Elevating the head of the bed

Correct answer: D

Rationale: Elevating the head of the bed is essential in the care of an infant with RSV as it helps improve breathing by reducing congestion and promoting drainage. This position also aids in maintaining patent airways and can enhance comfort for the infant. Providing small, frequent feedings (Choice A) is generally appropriate for infants but is not a specific intervention for RSV. Administering antibiotics (Choice B) is not indicated for RSV, as it is a viral infection and antibiotics are ineffective against viruses. Maintaining strict isolation (Choice C) is important to prevent the spread of infections, but it is not a direct care intervention for managing RSV symptoms.
