Pediatric Practice Exam HESI

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.

Correct Answer: D

Rationale: Full-thickness burns are characterized by a leathery, dry appearance with numbness due to nerve damage. Choice A describes characteristics of superficial burns, which are not full-thickness. Choice B describes characteristics of partial-thickness burns with intact blisters, not full-thickness burns. Choice C describes characteristics of partial-thickness burns with blistering and swelling, not full-thickness burns.

Correct Answer: C

Rationale: In a severe asthma attack, the child is likely to develop respiratory acidosis. This occurs due to impaired respirations, leading to the retention of carbon dioxide and the formation of carbonic acid. Choice A is incorrect as metabolic alkalosis is not expected in this situation. Choice B is incorrect as respiratory alkalosis does not align with the scenario of impaired respirations in severe asthma attacks. Choice D is also incorrect as it describes metabolic acidosis, which is not typically associated with severe asthma attacks.

Correct Answer: B

Rationale: The priority intervention for a 3-month-old infant hospitalized with respiratory syncytial virus (RSV) is to cluster care to conserve energy. Infants with RSV often have difficulty breathing and need to rest frequently. Clustering care involves grouping nursing interventions to allow for longer periods of rest between activities, which helps prevent exhaustion and conserve the infant's energy. Administering an antiviral agent is not the primary intervention for RSV, as it is a viral infection and antiviral agents are not typically used for RSV. Offering oral fluids is important for hydration but may not be the priority when the infant is struggling to breathe. Providing an antitussive agent should be done judiciously and under medical guidance, as suppressing the cough reflex can be detrimental in RSV cases where coughing helps clear airway secretions.

Correct Answer: B

Rationale: In cases of potential poisoning, immediate guidance from professionals is crucial. Administering syrup of ipecac is no longer recommended routinely due to potential risks and lack of benefit. Taking the child to the emergency department is necessary in severe cases but may not always be the immediate action needed. Giving the child bread dipped in milk is not an appropriate method to manage poisoning and could potentially worsen the situation. Therefore, the most appropriate action for the nurse to recommend is to call the poison control center for expert advice on managing the situation.
