Pediatric HESI Test Bank

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: C

Rationale: The correct answer is C: Right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta are the cardiac defects associated with Tetralogy of Fallot. In Tetralogy of Fallot, these specific abnormalities contribute to the classic features of the condition. Choice A is incorrect as it includes mitral valve stenosis, which is not typically part of Tetralogy of Fallot. Choice B describes transposition of the great arteries, not Tetralogy of Fallot. Choice D mentions an altered connection between the pulmonary artery and the aorta, which is not a defining characteristic of Tetralogy of Fallot.

Correct Answer: A

Rationale: The primary goal of therapy during the acute phase of Kawasaki disease is to prevent coronary artery aneurysms, which are a serious complication of this condition. Coronary artery aneurysms can lead to long-term cardiovascular issues, making prevention crucial. While reducing fever and improving cardiac function are important aspects of managing Kawasaki disease, the primary focus in the acute phase is on preventing coronary artery aneurysms. Dehydration prevention is also essential but not the primary goal during the acute phase of this disease.

Correct Answer: C

Rationale: The correct hematocrit range for a healthy 12-month-old infant is between 37% to 47%. At this age, this range reflects the normal blood volume and red blood cell (RBC) levels in infants. Choice A (19% to 32%) is too low for a healthy hematocrit level in a 12-month-old. Choice B (29% to 41%) is also below the typical range for a 12-month-old. Choice D (42% to 69%) includes an upper limit that is higher than expected for a healthy infant, making it an incorrect option.

Correct Answer: B

Rationale: Childhood obesity is a prevalent issue in children with Down syndrome due to factors such as decreased physical activity, slower metabolism, and potential overeating tendencies. Addressing obesity is crucial to promoting healthy lifestyles and preventing associated health complications. Rickets, a condition caused by a deficiency of vitamin D, is not commonly associated with Down syndrome. While anemia can occur in individuals with Down syndrome, obesity is a more common concern. Rumination, the regurgitation of food without nausea, is not a typical nutritional problem in children with Down syndrome.
