Pediatric Practice Exam HESI

Correct Answer: A

Rationale: The correct answer is A: Syndrome of inappropriate antidiuretic hormone (SIADH). Vasopressin is a medication used to treat diabetes insipidus by increasing water reabsorption in the kidneys. However, an excessive dose of vasopressin can lead to water retention, causing SIADH, which is characterized by dilutional hyponatremia. Choices B, C, and D are incorrect. Thyroid storm is a severe form of hyperthyroidism characterized by increased metabolism and can lead to life-threatening complications. Cushing syndrome results from excess cortisol production and is characterized by weight gain, hypertension, and other features. Vitamin D toxicity occurs due to an overdose of vitamin D, leading to hypercalcemia and symptoms such as nausea, vomiting, and weakness.

Correct Answer: B

Rationale: The priority nursing intervention for a child hospitalized for acute lymphoblastic leukemia (ALL) is preventing infection. Children with ALL have compromised immune systems, making them highly vulnerable to infections. Preventing infections through strict aseptic techniques, isolation precautions, and proper hygiene is crucial to safeguard the child's health. Administering antibiotics (choice A) may be necessary if an infection occurs, but the primary focus should be on infection prevention. While providing nutritional support (choice C) is important, preventing infection takes precedence due to its direct impact on the child's survival. Managing pain (choice D) is essential for the child's comfort but is not the priority over preventing life-threatening infections in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Put on gloves because standard precautions are required. Standard precautions, which include wearing gloves, are crucial in preventing the transmission of infections during immunization. Choice A is incorrect because the immediate action should be to address the lack of gloves. Choice C is incorrect as gloves are necessary for infection control. Choice D is incorrect as gloves should be worn as a standard preventive measure, regardless of the child's appearance.

Correct Answer: D

Rationale: In congenital hypothyroidism, infants often experience lethargy and difficulty staying awake due to low thyroid hormone levels. Choice A is incorrect as hypothyroidism can lead to poor growth in infants. Choice B is incorrect because hypothyroidism can cause decreased activity levels and lethargy rather than being active and playful. Choice C is incorrect as hypothyroidism can result in dry skin and poor skin tone, not necessarily pink and healthy-looking skin.

Correct Answer: B

Rationale: The correct approach for an alert 4-year-old child with a mild airway obstruction, respiratory distress, a strong cough, and normal skin color is to provide oxygen, avoid agitation, and arrange for transport. Oxygen helps support breathing, avoiding agitation prevents worsening of the obstruction, and transport ensures the child receives further medical evaluation and treatment. Choices A, C, and D involve techniques that are not recommended for a mild airway obstruction in this scenario. Back blows, abdominal thrusts, chest thrusts, and finger sweeps are interventions used for different situations and not suitable for a child with the described symptoms.
