Pediatric HESI Test Bank

Correct Answer: A

Rationale: For a 4-year-old child scheduled for a myringotomy, explaining the procedure in simple terms is essential in helping the child understand what will happen during the surgery and reducing anxiety. Encouraging fluid intake, allowing the child to play with medical equipment, and using play therapy are not directly related to preparing the child for the myringotomy procedure. Therefore, these options are incorrect and not as beneficial as explaining the procedure in simple terms.

Correct Answer: B

Rationale: Chest tubes are used to drain air and fluid from the chest cavity to prevent complications such as pneumothorax or cardiac tamponade after surgery. Choice A is incorrect as chest tubes are not used to increase tidal volumes. Choice C is incorrect as chest tubes do not maintain positive intrapleural pressure; instead, they assist in removing excess air or fluid. Choice D is incorrect as chest tubes do not regulate pressure on the pericardium and chest wall; they primarily aid in drainage.

Correct Answer: A

Rationale: Tachypnea, which refers to rapid breathing, is an early sign of congestive heart failure. In heart failure, the heart's inability to pump efficiently can lead to fluid accumulation in the lungs, causing the child to breathe faster to try to compensate for the decreased oxygen exchange. Bradycardia (slow heart rate) is not typically associated with congestive heart failure; instead, it may indicate a different issue. Inability to sweat is not a common early sign of congestive heart failure. Increased urinary output is not a typical early sign of congestive heart failure; instead, it may be a sign of other conditions like diabetes or kidney issues.

Correct Answer: A

Rationale: The correct answer is to rotate injection sites. This practice helps prevent lipodystrophy, a localized loss of fat tissue that can affect insulin absorption. By rotating sites, the child can avoid developing lumps or indentations in the skin where insulin is repeatedly injected. Administering insulin before meals (choice B) may be necessary for certain types of insulin but is not the priority when teaching about insulin administration. Storing insulin in the refrigerator (choice C) is important for maintaining its potency, but it is not the primary emphasis when teaching about insulin administration. Administering insulin at bedtime (choice D) may be necessary based on the child's insulin regimen but is not the primary consideration for teaching injection techniques and site rotation.

Correct Answer: B

Rationale: Choice B indicates a need for further teaching because participation in contact sports like football should be avoided in children with idiopathic thrombocytopenia due to the increased risk of bleeding. Choices A, C, and D are correct. Avoiding aspirin and medications like ibuprofen helps prevent bleeding complications. Swimming is a safe physical activity that can be recommended. Antihistamines do not pose a significant risk in this case and can be used if needed.
