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: C

Rationale: Elevating the affected area above the level of the heart is the correct supportive measure for a child with hemophilia who has experienced trauma. This action helps reduce bleeding and swelling by promoting venous return and preventing further pooling of blood in the affected area. Applying warm, moist compresses (Choice A) may not be recommended as it can potentially increase bleeding by dilating blood vessels. Applying pressure for at least 1 minute (Choice B) can be helpful for minor cuts or wounds but may not be as effective in managing bleeding in a child with hemophilia. Beginning passive range-of-motion (Choice D) should be avoided as it can exacerbate bleeding and cause further damage in a child with hemophilia.

Correct Answer: C

Rationale: A caring relationship with family members is an external protective factor that promotes resilience in individuals, especially in adolescents. This support system provides a sense of security, stability, and emotional connection, which can help the teenager navigate challenges and setbacks. Choices A, B, and D allude to internal factors related to personal decision-making, self-awareness, and goal management, which are important but do not directly represent external protective factors involving external relationships or resources.

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.

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.
