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: A

Rationale: The priority nursing action after a tracheostomy surgery is to suction the tracheostomy tube. Suctioning helps maintain a clear airway and prevent complications such as airway obstruction or respiratory distress. While monitoring respiratory status is important, suctioning takes precedence immediately post-surgery to ensure adequate air exchange. Changing the tracheostomy dressing and ensuring tracheostomy ties are secure are also essential tasks but are secondary to the critical need for airway maintenance through suctioning.

Correct Answer: A

Rationale: In situations of divorce, it is crucial for both parents to inform the child together using age-appropriate language. This approach helps maintain consistency and clarity for the child, reducing confusion and anxiety. Choice B is incorrect because reassurance should not be solely focused on love but on explaining the situation appropriately. Choice C may inadvertently send the message that the divorce is the child's fault or requires compensation. Choice D is incorrect as children benefit from understanding and processing emotions in a healthy manner, rather than having them kept hidden.

Correct Answer: B

Rationale: A cross-cut nipple is the most appropriate method to feed an infant born with a unilateral cleft lip and palate. Using a cross-cut nipple allows for easier feeding by modifying the flow of milk, which helps in reducing the risk of aspiration in infants with this condition. Plastic spoon, parenteral infusion, and rubber-tipped syringe are not suitable for feeding infants with cleft lip and palate. Feeding an infant with a cleft lip and palate requires special considerations to ensure safe and effective nutrition delivery.

Correct Answer: B

Rationale: The correct answer is B. Tap water enemas can cause significant fluid and electrolyte imbalances, particularly in infants, making them unsafe for this age group. Choice A is incorrect because tap water enemas do not directly lead to loss of necessary nutrients. Choice C is incorrect as it focuses on emotional impact rather than physiological risks. Choice D is incorrect as shock from a sudden drop in temperature is not a common consequence of a tap water enema in this scenario.
