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: B

Rationale: The correct dietary instruction for a 2-year-old child with GERD is to avoid gluten. Gluten is a protein found in wheat, barley, and rye that can worsen GERD symptoms. Avoiding gluten can help reduce inflammation and discomfort in the esophagus. Choices A, C, and D are incorrect because spicy foods, high-fat foods, and dairy products can exacerbate GERD symptoms. Spicy foods can irritate the esophagus, high-fat foods delay stomach emptying leading to increased acid reflux, and dairy products can stimulate acid production, all of which can worsen GERD symptoms.

Correct Answer: C

Rationale: The correct answer is C. Using echolalia, which is the repetition of words or phrases, is not typical for a 2-year-old child and may indicate the need for further evaluation. Choices A, B, and D are all within the expected developmental skills for a 2-year-old. While most 2-year-olds may not be able to stand on one foot, it is not a cause for concern at this age. Building a tower of 7 blocks and coloring outside the lines of a picture are both appropriate for a 2-year-old's developmental skills.

Correct Answer: C

Rationale: The correct supportive measure for the school nurse to use for a boy with hemophilia who fell on his arm during recess is to elevate the area above the level of the heart. Elevating the affected area helps reduce bleeding and swelling in a child with hemophilia until factor replacement therapy can be provided. Applying warm, moist compresses (Choice A) may worsen bleeding by dilating blood vessels. Applying pressure for at least 1 minute (Choice B) is not recommended for hemophilia as it can lead to increased bleeding. Beginning passive range-of-motion (Choice D) should be avoided as it can exacerbate bleeding and further injury in a child with hemophilia.

Correct Answer: A

Rationale: Rubeola (measles) is characterized by a high fever and the presence of Koplik spots, which are not seen in rubella (German measles). Therefore, the correct answer is A. Choice B, rash on the trunk with pruritus, is more indicative of rubella rather than rubeola. Choice C, nausea, vomiting, and abdominal cramps, are not specific differentiating symptoms between rubeola and rubella. Choice D, characteristics of a cold followed by a rash, does not specifically distinguish between rubeola and rubella.
