Nursing Elites

1. A four-year-old boy is admitted to the hospital with leg pain and fever. He is pale-looking and has bruises over various areas of his body. The physician suspects acute lymphoblastic leukemia (ALL). Which test would be used to confirm the diagnosis?

• A. Bone marrow aspirate
• B. Red blood cell count
• C. Lumbar puncture
• D. Bone scan

Correct answer: A

Rationale: A bone marrow aspirate is the definitive test to confirm acute lymphoblastic leukemia (ALL) in this case. It allows for the examination of leukemic cells in the bone marrow, providing a direct assessment of the disease. Red blood cell count (Choice B) is not specific for diagnosing leukemia but may show anemia commonly seen in leukemia patients. Lumbar puncture (Choice C) is used to assess central nervous system involvement, not primarily for confirming ALL. Bone scan (Choice D) is not a standard diagnostic test for ALL and is mainly used for evaluating bone metastases in other conditions.

2. Which reflex, present at birth, is elicited by stroking the sole of the infant's foot, resulting in the fanning of the toes?

• A. Babinski
• B. Moro
• C. Sucking
• D. Rooting

Correct answer: A

Rationale: The Babinski reflex is the correct answer. This reflex is characterized by the fanning out of the toes when the sole of the foot is stroked. It is a normal reflex in infants and is typically present at birth, disappearing by around 12 months of age. The Moro reflex, which involves the infant's response to a sudden loss of support or a loud noise, is not related to the fanning of toes. Sucking and rooting reflexes are related to feeding behaviors and are not elicited by stroking the sole of the foot.

3. Parents of a preschool child ask the nurse, "Should we set rules for our child as part of a discipline plan?" Which is an accurate response by the nurse?

• A. It is best to delay the punishment if a rule is broken.
• B. The child is too young for rules. At this age, unrestricted freedom is best.
• C. It is best to set the rules and reason with the child when the rules are broken.
• D. Set clear and reasonable rules and expect the same behavior regardless of the circumstances.

Correct answer: D

Rationale: Clear and reasonable rules provide structure and help children understand expectations, promoting consistent behavior and discipline.

4. Why are neonates predisposed to problems with thermoregulation?

• A. Renal function is not fully developed
• B. Flexed posture favors heat loss
• C. A large body surface area favors heat loss to the environment
• D. A thick layer of subcutaneous fat provides excellent insulation

Correct answer: C

Rationale: Newborns have a large surface area relative to their body weight, making them more susceptible to heat loss and requiring careful thermoregulation. Choice A is incorrect because renal function is not directly related to thermoregulation. Choice B is incorrect because a flexed posture actually helps reduce heat loss by minimizing the surface area exposed to the environment. Choice D is incorrect because neonates have limited subcutaneous fat, which contributes to their susceptibility to heat loss.

5. A child is admitted for minimal change nephrotic syndrome (MCNS). The nurse recognizes that the child’s prognosis is related to what factor?

• A. Admission blood pressure
• B. Creatinine clearance
• C. Amount of protein in urine
• D. Response to steroid therapy

Correct answer: D

Rationale: The prognosis for children with MCNS is closely related to their response to steroid therapy. A favorable response to steroids usually indicates a better prognosis, while poor response may require alternative treatments and can indicate a more complicated disease course.
