Pediatrics HESI 2023 Questions
Question 1 of 5
A nurse is caring for an infant with intractable vomiting. For what complication is it most important for the nurse to assess?
Correct Answer: B
Rationale: When an infant experiences intractable vomiting, it can lead to the loss of stomach acids, resulting in metabolic alkalosis. Alkalosis is characterized by elevated blood pH and can lead to serious complications. Assessing for alkalosis is essential in this scenario to monitor and manage the infant's condition. Choices A, C, and D are incorrect because in this context, the primary concern is the metabolic imbalance caused by excessive vomiting, leading to alkalosis rather than acidosis, hyperkalemia, or hypernatremia.
Question 2 of 5
A nurse is inspecting the skin of a child with atopic dermatitis. What would the nurse expect to observe?
Correct Answer: B
Rationale: In atopic dermatitis, the nurse would expect to observe a dry, red, scaly rash with lichenification. Lichenification is thickened skin due to chronic scratching. Choices A, C, and D are incorrect. Erythematous papulovesicular rash is more characteristic of contact dermatitis, pustular vesicles with honey-colored exudates are seen in impetigo, and hypopigmented oval scaly lesions are typical of pityriasis alba.
Question 3 of 5
The child has been admitted for a sickle cell crisis. What would the nurse do first to provide adequate pain management?
Correct Answer: D
Rationale: Initiating pain assessment with a standardized pain scale is crucial in managing pain effectively during a sickle cell crisis. This step allows the nurse to objectively evaluate the child's pain level and tailor the pain management plan accordingly. Administering medication without a proper assessment could lead to inappropriate pain management. Using guided imagery and therapeutic touch may be beneficial as adjunct therapies but should not replace the initial pain assessment. Meperidine is not typically the first-line choice for pain management in sickle cell crisis due to its potential for neurotoxic metabolites.
Question 4 of 5
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?
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.
Question 5 of 5
What explanation should be given to a parent about the purpose of a tetanus toxoid injection for their child?
Correct Answer: B
Rationale: The correct answer is B: 'Long-lasting active immunity is conferred.' Tetanus toxoid injection provides long-lasting active immunity by stimulating the body to produce its own antibodies. Choice A is incorrect because tetanus toxoid injection does not provide passive immunity. Choice C is incorrect because the immunity conferred by the vaccine is not natural but artificially induced. Choice D is incorrect as the immunity provided by the tetanus toxoid injection is active, not passive.
