Pediatric Practice Exam HESI
1. A nurse on the pediatric unit is observing the developmental skills of several 2-year-old children in the playroom. Which child should the nurse continue to evaluate?
- A. Cannot stand on one foot
- B. Builds a tower of 7 blocks
- C. Uses echolalia when speaking
- D. Colors outside the lines of a picture
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.
2. A newborn is admitted to the neonatal intensive care unit (NICU) with choanal atresia. Which part of the infant’s body should the nurse assess?
- A. Rectum
- B. Nasopharynx
- C. Intestinal tract
- D. Laryngopharynx
Correct answer: B
Rationale: Choanal atresia is a congenital condition characterized by the blockage of the nasal passages, specifically the choanae that connect the nasal cavity to the nasopharynx. The nurse should assess the nasopharynx to identify any obstruction, confirm the diagnosis, and assess the severity of the condition. Choices A, C, and D are incorrect as they do not pertain to choanal atresia. Choanal atresia specifically involves the nasal passages and nasopharynx, not the rectum, intestinal tract, or laryngopharynx.
3. Which of the following signs or symptoms is more common in children than adults following head trauma?
- A. nausea and vomiting
- B. altered mental status
- C. tachycardia and diaphoresis
- D. changes in pupillary reaction
Correct answer: A
Rationale: Nausea and vomiting are more common in children following head trauma due to their higher risk of increased intracranial pressure. Children have less space for swelling within the skull compared to adults, making them more prone to experiencing symptoms like nausea and vomiting. Altered mental status and changes in pupillary reaction can also occur in both children and adults following head trauma, but they are not specifically more common in children. Tachycardia and diaphoresis are generally signs of autonomic nervous system activation and may occur in both children and adults, but they are not typically more common in children compared to adults following head trauma.
4. When teaching a class of new parents about positioning their infants during the first few weeks of life, which position is safest?
- A. On the back, lying flat
- B. On either side, lying flat
- C. Head slightly elevated on the left side
- D. Head slightly elevated on the right side
Correct answer: A
Rationale: The correct answer is A: 'On the back, lying flat'. Placing infants on their back to sleep is recommended to reduce the risk of sudden infant death syndrome (SIDS). This position helps ensure the baby's airway remains clear and reduces the likelihood of suffocation. Choices B, C, and D are not as safe as placing the infant on their back, as they may increase the risk of accidental suffocation or SIDS.
5. A group of students is reviewing the components of the endocrine system. The students demonstrate understanding of the review when they identify what as the primary function of this system?
- A. Regulation of water balance
- B. Hormonal secretion
- C. Cellular metabolism
- D. Growth stimulation
Correct answer: B
Rationale: The primary function of the endocrine system is hormonal secretion. This system is responsible for producing and releasing hormones that regulate various bodily functions such as growth, metabolism, and mood. Choice A, regulation of water balance, is more related to the functions of the renal system rather than the endocrine system. Choice C, cellular metabolism, is a general cellular process that involves various systems, not specific to the endocrine system. Choice D, growth stimulation, though hormones can influence growth, it is not the primary function of the endocrine system. Therefore, the correct answer is B.
