Pediatric Practice Exam HESI

Correct Answer: B

Rationale: Setting the water heater at 130 degrees can lead to scald burns. The recommended temperature setting for water heaters is no higher than 120 degrees to prevent burns. Choice A is correct as it shows awareness of the risks of fireworks. Choice C is correct as flame-retardant sleepwear can help prevent burns. Choice D is correct as inward-facing pot handles prevent accidental spills and burns. Option B is incorrect due to the unsafe water heater temperature setting.

Correct Answer: A

Rationale: The correct answer is A: 'High fever and Koplik spots.' Rubeola (measles) is characterized by a high fever and the presence of Koplik spots, which are not seen in rubella (German measles). Choice B, rash on the trunk with pruritus, is more indicative of rubella. Choice C, nausea, vomiting, and abdominal cramps, are not specific to either rubeola or rubella. Choice D, characteristics of a cold followed by a rash, is not a typical presentation of rubeola or rubella.

Correct Answer: B

Rationale: In cases of potential poisoning, the best immediate action to take is to call the poison control center. Administering syrup of ipecac is no longer recommended as it can lead to complications such as aspiration and may interfere with subsequent treatments. Taking the child to the emergency department should only be done if advised by the poison control center or if the child is showing severe symptoms. Giving bread dipped in milk to absorb the poison is not an appropriate or effective treatment for poisoning, as it does not address the toxicity of the ingested substance and may delay appropriate medical interventions.

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: D

Rationale: Hypospadias is a congenital condition where the urethral opening is located along the ventral surface of the penis, not the dorsal surface (Choice C) or absent (Choice A). This leads to the characteristic appearance of a ventrally displaced urethral meatus. The penis may appear normal in size but with the urethral opening positioned abnormally (Choice D), rather than being shorter than usual (Choice B). Therefore, the correct expectation for a newborn with hypospadias is that the urethral opening is along the ventral surface of the penis, making Choice D the correct answer.
