Nursing Elites

1. A child has been admitted to the pediatric unit with a severe asthma attack. What type of acid-base imbalance should the nurse expect the child to develop?

• A. metabolic alkalosis due to insufficient production of acid metabolites
• B. respiratory alkalosis due to depressed respirations and retention of carbon dioxide
• C. respiratory acidosis due to impaired respirations and increased formation of carbonic acid
• D. metabolic acidosis due to the kidneys' inability to compensate for decreased carbonic acid formation

Correct answer: C

Rationale: In a severe asthma attack, the child is likely to develop respiratory acidosis. This occurs due to impaired respirations, leading to the retention of carbon dioxide and the formation of carbonic acid. Choice A is incorrect as metabolic alkalosis is not expected in this situation. Choice B is incorrect as respiratory alkalosis does not align with the scenario of impaired respirations in severe asthma attacks. Choice D is also incorrect as it describes metabolic acidosis, which is not typically associated with severe asthma attacks.

2. When describing urticaria, what would an instructor include?

• A. It is a type IV hypersensitivity reaction.
• B. Histamine release leads to vasodilation.
• C. Wheals appear first followed by erythema.
• D. The nonpruritic rash blanches with pressure.

Correct answer: B

Rationale: The correct answer is B. Urticaria is a type I hypersensitivity reaction where histamine release leads to vasodilation and the formation of characteristic wheals. Choice A is incorrect as urticaria is associated with type I hypersensitivity, not type IV. Choice C is incorrect because in urticaria, erythema typically appears before the development of wheals. Choice D is incorrect as urticaria is typically pruritic and does not blanch with pressure.

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

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

Correct answer: B

Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs in response to chronic hypoxia, leading the body to increase red blood cell production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect that results in reduced oxygen levels in the blood, the body compensates by producing more red blood cells. Choice A is incorrect as low tissue oxygen needs would not trigger polycythemia. Choice C, diminished iron levels, is not the cause of polycythemia in this case. Choice D, hypertrophic cardiac muscle, is unrelated to the pathophysiology of polycythemia in tetralogy of Fallot.

4. A 34-year-old woman, who is 36 weeks pregnant, is having a seizure. After you protect her airway and ensure adequate ventilation, you should transport her

• A. on her left side
• B. in the prone position
• C. in the supine position
• D. in a semi-sitting position

Correct answer: A

Rationale: Transporting a pregnant woman who is having a seizure on her left side is crucial as it helps improve blood flow to the fetus and reduces the risk of further complications. Placing her in the prone position or supine position may compromise blood flow to the fetus and worsen the situation. A semi-sitting position is also not recommended as it may not provide optimal blood flow to the fetus or adequately protect the airway during a seizure.

5. The nurse is assessing a child with a possible fracture. What would the nurse identify as the most reliable indicator?

• A. Lack of spontaneous movement
• B. Point tenderness
• C. Bruising
• D. Inability to bear weight

Correct answer: B

Rationale: Point tenderness is the most reliable indicator of a possible fracture in a child. It is a localized tenderness experienced when pressure is applied to a specific area, suggesting a potential fracture. This tenderness is considered more specific to a fracture than other symptoms such as lack of spontaneous movement, bruising, or inability to bear weight. Lack of spontaneous movement and inability to bear weight can be present in various musculoskeletal injuries, while bruising may not always be immediate or specific to a fracture.
