Pediatric Practice Exam HESI

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: B

Rationale: The correct answer is B. Tap water enemas can cause significant fluid and electrolyte imbalances, particularly in infants, making them unsafe for this age group. Choice A is incorrect because tap water enemas are unlikely to lead to loss of necessary nutrients. Choice C is incorrect as it does not directly relate to the physiological risk of tap water enemas. Choice D is incorrect as shock from a sudden drop in temperature is not a common concern with tap water enemas.

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: C

Rationale: The correct answer is to look along the scalp line for white dots (nits) when checking for head lice. White dots are indicative of head lice infestation. Itching alone, as mentioned in choice A, is not a reliable indicator of head lice. Choice B is irrelevant as it refers to checking for ear mites in a dog, not head lice in a human. Observing between the fingers for red lines, as in choice D, is not a method to check for head lice.

Correct Answer: B

Rationale: Choanal atresia is a congenital condition that presents with a blockage in the nasal passages at the junction of the nasal cavity and the nasopharynx. To assess and confirm the diagnosis of choanal atresia, the nurse should focus on assessing the nasopharynx. Choices A, C, and D are incorrect as choanal atresia specifically involves a blockage in the nasal passages, not the rectum, intestinal tract, or laryngopharynx. By assessing the nasopharynx, the severity of the obstruction can be determined, aiding in planning appropriate interventions for the newborn.
