Pediatric HESI Test Bank

Correct Answer: C

Rationale: Administering antibiotics is a crucial nursing intervention after a tonsillectomy because it helps prevent infections, which are a common postoperative complication. Encouraging deep breathing exercises (Choice A) is also important for promoting lung expansion and preventing respiratory complications. Encouraging the child to eat (Choice B) may not be appropriate immediately after a tonsillectomy due to the risk of throat irritation and discomfort. Applying ice to the throat (Choice D) is generally not recommended post-tonsillectomy as it may cause vasoconstriction and hinder the healing process.

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 is an early sign of congestive heart failure that nurses should recognize. Tachypnea refers to rapid breathing, which can be an indication of the body's attempt to compensate for decreased cardiac output in congestive heart failure. Bradycardia (choice B) is a slow heart rate and is not typically associated with congestive heart failure. Inability to sweat (choice C) and increased urinary output (choice D) are not specific early signs of congestive heart failure and are not typically recognized as such.

Correct Answer: C

Rationale: The correct answer is C: Phenylketonuria (PKU). PKU is suggested by a mousy or musty odor of the urine, which is caused by the inability to metabolize phenylalanine. Choice A, Maple syrup urine disease, is characterized by a sweet-smelling urine. Choice B, Tyrosinemia, typically presents with cabbage-like odor in the urine. Choice D, Trimethylaminuria, is associated with a fishy odor in the urine, breath, and sweat.

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.
