Pediatric HESI Test Bank

Correct Answer: A

Rationale: The primary goal of therapy during the acute phase of Kawasaki disease is to prevent coronary artery aneurysms. Kawasaki disease is characterized by systemic vasculitis and the most serious complication is the development of coronary artery aneurysms. While reducing fever and improving cardiac function are important aspects of managing Kawasaki disease, the primary focus in the acute phase is to prevent the development of coronary artery aneurysms. Preventing dehydration is also essential but not the primary goal in managing Kawasaki disease.

Correct Answer: C

Rationale: The correct answer is C. Excessive thirst (polydipsia) is a common symptom of type 2 diabetes mellitus, indicating high blood glucose levels. This symptom occurs due to the body trying to get rid of excess glucose through urine, leading to dehydration and increased thirst. Choices A, B, and D are incorrect. Choice A is more indicative of a recent viral illness rather than a symptom of diabetes. Choice B, decreased blood pressure, is not typically associated with type 2 diabetes; in fact, diabetes can often lead to hypertension. Choice D, Kussmaul breathing, is more characteristic of diabetic ketoacidosis, which is more common in type 1 diabetes rather than type 2 diabetes.

Correct Answer: B

Rationale: The best initial action during a tonic-clonic seizure is to place the child on the floor. This action helps prevent injury by providing a safe environment and allows for better management of the seizure episode. Attempting to open the jaw is not recommended as it may cause harm to the child or the nurse. Calling out for assistance is important but should not delay ensuring the child's safety first. Placing a pillow under the child's head is not advisable during a seizure as it can pose a risk of suffocation or choking.

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: The correct answer is B. Urticaria is a type I hypersensitivity reaction, not type IV. When triggered, histamine release leads to vasodilation, causing characteristic wheals. Wheals are typically followed by erythema. The rash in urticaria is pruritic and does blanch with pressure, unlike the nonpruritic rash described in choice D. Therefore, the most appropriate description of urticaria includes histamine release and vasodilation, as stated in choice B.
