Pediatric Practice Exam HESI

Correct Answer: B

Rationale: The correct answer is B. Setting the water heater at 130 degrees is incorrect because water heaters should be set to no higher than 120 degrees to prevent scald burns. Choice A is correct as leaving fireworks displays to professionals reduces the risk of burns. Choice C is also correct as flame-retardant sleepwear reduces the risk of burn injuries. Choice D is correct as keeping pot handles facing inward prevents accidental spills and burns.

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: The priority nursing intervention for a child with leukemia receiving chemotherapy is monitoring for signs of infection. Chemotherapy can suppress the immune system, putting the child at a higher risk of developing infections. Early detection of signs of infection is crucial to prevent serious complications and initiate timely treatment. Providing nutritional support is important for overall health but is not the priority when the child is at risk of infection. Monitoring for signs of bleeding is essential, but infection surveillance takes precedence due to the immediate threat it poses to the child's health. Monitoring for signs of pain is important for comfort but is not the priority over infection prevention and management.

Correct Answer: C

Rationale: The correct answer is C because using echolalia (repeating words or phrases) is not typical for a 2-year-old and may indicate the need for further evaluation. Choices A, B, and D are within the expected developmental skills for a 2-year-old. While a 2-year-old may not be able to stand on one foot for an extended period, it is not a concerning developmental milestone at this age. Building a tower of 7 blocks and coloring outside the lines of a picture are both age-appropriate activities that demonstrate fine motor skills and creativity, respectively. However, echolalia at this age could be a sign of an underlying communication or developmental issue that warrants further assessment and monitoring.

Correct Answer: C

Rationale: In a severe asthma attack, the child is likely to develop respiratory acidosis due to impaired respirations leading to the retention of carbon dioxide, which combines with water to form carbonic acid. This results in the pH imbalance characterized by an excess of carbonic acid. Choices A, B, and D are incorrect. Metabolic alkalosis (Choice A) is not typically associated with severe asthma attacks; respiratory alkalosis (Choice B) would involve a decrease, not an increase, in carbon dioxide levels; and metabolic acidosis (Choice D) is not the primary acid-base imbalance seen in severe asthma attacks.
