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. In a case where a limb is protruding from a mother's vagina during active labor, how should this condition be managed?

• A. Positioning the mother in a semi-Fowler's position, administering oxygen, and providing transport
• B. Positioning the mother in a head-down position with her hips elevated, administering oxygen, and providing transport
• C. Applying gentle traction to the protruding limb to remove pressure of the fetus from the umbilical cord
• D. Giving the mother 100% oxygen and attempting to manipulate the protruding limb so that delivery can occur

Correct answer: B

Rationale: When a limb is protruding from the vagina during active labor, the appropriate management includes positioning the mother in a head-down position with her hips elevated. This position helps relieve pressure on the umbilical cord, reducing the risk of compromising fetal blood flow and oxygenation. Administering oxygen is essential to maintain oxygenation levels for both the mother and the fetus. Providing transport to a healthcare facility equipped to manage this obstetric emergency is crucial for ensuring a safe delivery. Choice A is incorrect because a semi-Fowler's position does not effectively relieve pressure on the umbilical cord. Choice C is incorrect as applying traction to the protruding limb can lead to injury or complications for both the mother and the fetus. Choice D is incorrect because attempting to manipulate the limb without proper positioning and preparation can worsen the situation and increase risks during delivery.

3. On the third day of hospitalization, the nurse observes that a 2-year-old toddler who had been screaming and crying inconsolably begins to regress and is now lying quietly in the crib with a blanket. What stage of separation anxiety has developed?

• A. Denial
• B. Despair
• C. Mistrust
• D. Rejection

Correct answer: B

Rationale: The correct answer is B: Despair. In separation anxiety, the stage of despair is characterized by regression and withdrawal after an initial period of protest. The child may become quiet and appear to accept the separation, but this is actually a sign of deeper distress. Choice A, Denial, is incorrect as it refers to refusing to believe or accept the reality of the separation. Choice C, Mistrust, is incorrect as it pertains to a lack of trust in others, not a stage of separation anxiety. Choice D, Rejection, is incorrect as it involves pushing others away and not related to the described behavior of the toddler in the scenario.

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. Lead exposure can lead to behavioral changes, including irritability, which is crucial for parents to recognize. While abdominal pain and constipation can occur in lead poisoning, they are not as specific or prominent as irritability. Frequent urination is not typically associated with lead poisoning in toddlers, making it a less relevant symptom to emphasize. By highlighting irritability, parents can be better equipped to identify potential signs of lead poisoning in their toddler.

5. A healthcare professional is assessing a child with suspected rotavirus infection. What clinical manifestation is the healthcare professional likely to observe?

• A. Abdominal pain
• B. Diarrhea
• C. Constipation
• D. Vomiting

Correct answer: B

Rationale: The correct answer is B: Diarrhea. Rotavirus infection commonly presents with symptoms such as watery diarrhea, fever, vomiting, and abdominal pain. However, diarrhea is the hallmark symptom of rotavirus infection, often leading to dehydration in children. Abdominal pain (choice A) can also be present but is not as specific to rotavirus infection as diarrhea. Constipation (choice C) is not a typical symptom of rotavirus infection. While vomiting (choice D) can occur in rotavirus infection, it is more commonly associated with other gastrointestinal conditions.
