Pediatric Practice Exam HESI

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.

Correct Answer: C

Rationale: The priority nursing intervention for a 4-year-old child admitted to the hospital with epiglottitis is to keep the child NPO (nothing by mouth). Epiglottitis is a serious condition that can lead to airway obstruction. Keeping the child NPO helps prevent further compromise of the airway and reduces the risk of aspiration. Administering antibiotics may be necessary but ensuring the airway is not compromised takes precedence. Providing humidified oxygen is important for respiratory support, but not the priority over maintaining a patent airway. Positioning the child upright can help with breathing and comfort, but it does not directly address the immediate risk of airway compromise associated with epiglottitis.

Correct Answer: A

Rationale: The priority nursing action after a child has undergone tracheostomy surgery is to suction the tracheostomy tube. Suctioning is crucial to maintain a clear airway, remove secretions, and prevent potential airway obstruction, which is essential for the child's respiratory function. Changing the tracheostomy dressing, while important for wound care, does not take precedence over airway clearance. Monitoring respiratory status is vital but comes after ensuring airway patency. Ensuring tracheostomy ties are secure is significant for stabilizing the tube but is not as urgent as maintaining a patent airway through suctioning.

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: When a child with diabetes insipidus is treated with vasopressin, the nurse should closely monitor for signs and symptoms of Syndrome of Inappropriate Antidiuretic Hormone (SIADH). Vasopressin, also known as antidiuretic hormone, helps retain water in the body. Excessive vasopressin administration can lead to water retention, dilutional hyponatremia, and potentially result in SIADH. Choices B, C, and D are incorrect because they are not directly associated with the use of vasopressin in treating diabetes insipidus.
