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. After clearing the airway of a newborn who is not in distress, what is the most important action to take next?

• A. Administer free-flow oxygen
• B. Clamp and cut the cord
• C. Keep the newborn warm
• D. Obtain an APGAR score

Correct answer: C

Rationale: Keeping the newborn warm is crucial immediately after clearing the airway to prevent hypothermia, which can lead to complications in newborns. Administering free-flow oxygen is not necessary if the newborn is not in distress. Clamping and cutting the cord can be done after ensuring the newborn's warmth. Obtaining an APGAR score is important but can be done after ensuring the newborn is kept warm and stable.

3. A home care nurse is visiting a family for the first time. The 4-week-old infant had surgery for exstrophy of the bladder and creation of an ileal conduit soon after birth. When the nurse arrives, the mother appears tired, and the baby is crying. After an introduction, which is the most appropriate statement by the nurse?

• A. “Tell me about your daily routine.”
• B. “You look tired. Is everything alright?”
• C. “When was the last time the baby had a bottle?”
• D. “Oh, it looks like you two are having a bad day.”

Correct answer: A

Rationale: Asking about the daily routine is the most appropriate statement by the nurse in this scenario. It allows the nurse to gather important information about the family's schedule, feeding patterns, and overall care routine for the infant. This open-ended question helps the nurse assess the family's situation comprehensively and identify any areas where support may be needed. Choices B, C, and D are less appropriate as they do not focus on gathering relevant information about the family's routine and needs but rather make assumptions or ask about specific isolated events.

4. A nurse is teaching the parents of a toddler about the signs and symptoms of lead poisoning. Which symptom should the nurse emphasize?

• A. Abdominal pain
• B. Constipation
• C. Irritability
• D. Frequent urination

Correct answer: C

Rationale: Irritability is a significant symptom of lead poisoning in toddlers and should be emphasized to parents. Lead poisoning can manifest with various symptoms, but irritability is particularly common in children exposed to lead. Abdominal pain (Choice A) is not a typical symptom of lead poisoning in toddlers. While constipation (Choice B) can occur, it is less specific and less common than irritability. Frequent urination (Choice D) is not a typical symptom associated with lead poisoning in toddlers and is less relevant for parents to recognize in this context.

5. The nurse is caring for an infant with suspected pyloric stenosis. Which clinical manifestation would indicate pyloric stenosis?

• A. abdominal rigidity and pain on palpation
• B. rounded abdomen and hypoactive bowel sounds
• C. visible peristalsis and weight loss
• D. distention of the lower abdomen and constipation

Correct answer: C

Rationale: Visible peristalsis and weight loss are classic clinical manifestations of pyloric stenosis. The obstruction at the pyloric sphincter causes visible peristalsis as the stomach tries to push food through the narrowed opening, leading to the appearance of waves across the abdomen. Weight loss occurs due to poor feeding and frequent vomiting associated with pyloric stenosis. Choices A, B, and D are incorrect. Abdominal rigidity and pain on palpation, rounded abdomen and hypoactive bowel sounds, as well as distention of the lower abdomen and constipation are not typically seen in pyloric stenosis.
