Pediatric Practice Exam HESI

Correct Answer: B

Rationale: The priority nursing intervention for a child with acute lymphoblastic leukemia (ALL) is preventing infection due to their compromised immune system. Children undergoing treatment for ALL are highly susceptible to infections, making infection prevention crucial for the child's well-being and treatment success. Administering antibiotics, though important in specific cases, is not the priority in this scenario. Providing nutritional support and managing pain are significant aspects of care but take a back seat to infection prevention in this situation.

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 4-year-old child admitted with bacterial pneumonia is administering antibiotics. Antibiotics are essential to treat the infection, prevent its spread, and avoid potential complications. Administering antipyretics (Choice A) may help reduce fever but does not address the underlying cause of pneumonia, which is bacterial in this case. Monitoring fluid intake (Choice C) is important to maintain hydration but does not directly treat the infection. Providing nutritional support (Choice D) is crucial for overall health, but the immediate priority is to address the bacterial infection with antibiotics to prevent further complications and promote recovery.

Correct Answer: B

Rationale: Setting the water heater at 130 degrees can lead to scald burns. The recommended temperature setting for water heaters is no higher than 120 degrees to prevent burns. Choice A is correct as it shows awareness of the risks of fireworks. Choice C is correct as flame-retardant sleepwear can help prevent burns. Choice D is correct as inward-facing pot handles prevent accidental spills and burns. Option B is incorrect due to the unsafe water heater temperature setting.

Correct Answer: C

Rationale: Placing the child in a semi-Fowler's position after eating is beneficial for reducing symptoms of gastroesophageal reflux. This position helps prevent gastric contents from flowing back into the esophagus. The supine position (choice A) may worsen reflux symptoms by allowing gravity to assist in reflux, leading to discomfort and regurgitation. Prone position (choice B) is not recommended after eating as it may cause discomfort and increase the risk of aspiration due to pressure on the stomach. Trendelenburg position (choice D), with the head lower than the rest of the body, is not indicated for managing GERD after eating and may not provide the desired benefits in this context.
