Pediatric Practice Exam HESI

Correct Answer: B

Rationale: The priority nursing intervention in a 4-year-old child admitted with bacterial pneumonia is administering antibiotics. Antibiotics are crucial for treating the infection and preventing potential complications. Administering antipyretics (Choice A) may help reduce fever, but addressing the underlying infection with antibiotics is the priority. Monitoring fluid intake (Choice C) is important for hydration but does not take precedence over administering antibiotics. Providing nutritional support (Choice D) is essential for overall care but is not the immediate priority when managing bacterial pneumonia.

Correct Answer: D

Rationale: Withholding extraordinary care in cases of severe abnormalities is a legal and ethical decision. It allows the newborn to die naturally without aggressive interventions. Choice A is incorrect because all individuals, including newborns, have rights. Choice B is incorrect because withholding extraordinary care is not equivalent to euthanasia, which involves actively ending a life. Choice C is incorrect because such decisions are legally and ethically permissible when made in consideration of the best interests of the newborn.

Correct Answer: C

Rationale: Placing the child in a semi-Fowler's position after eating is beneficial for reducing symptoms of gastroesophageal reflux. This position helps prevent gastric contents from flowing back into the esophagus. The supine position (choice A) may worsen reflux symptoms by allowing gravity to assist in reflux, leading to discomfort and regurgitation. Prone position (choice B) is not recommended after eating as it may cause discomfort and increase the risk of aspiration due to pressure on the stomach. Trendelenburg position (choice D), with the head lower than the rest of the body, is not indicated for managing GERD after eating and may not provide the desired benefits in this context.

Correct Answer: C

Rationale: The correct answer is to look along the scalp line for white dots (nits) when checking for head lice. White dots/nits are the eggs of head lice and are commonly found attached to the hair shaft near the scalp. This method helps identify if head lice are present. Choice A is incorrect as itching alone may not be a definitive sign of head lice; it could be due to other reasons. Choice B is irrelevant as ear mites in dogs are not related to head lice infestation in humans. Choice D is also incorrect as observing between the fingers for red lines is not a method for checking head lice.

Correct Answer: A

Rationale: When a child has coarctation of the aorta, the nurse would expect to identify a weak radial pulse when taking the child's vital signs. Coarctation of the aorta results in a narrowing of the aorta, leading to reduced blood flow and a weakened pulse. An irregular heartbeat (Choice B) is less likely to be associated with coarctation of the aorta. Similarly, a bounding femoral pulse (Choice C) is not typically observed with this condition. An elevated radial blood pressure (Choice D) is less common as coarctation of the aorta usually causes decreased blood pressure in the lower extremities due to the aortic narrowing.
