HESI Pediatrics Quizlet Questions
Question 1 of 5
Why does a cleft lip predispose an infant to infection?
Correct Answer: D
Rationale: The correct answer is D. Mouth breathing due to a cleft lip can dry the mucous membranes, making them more susceptible to infection. Choice A is incorrect because waste products do not accumulate along the defect to predispose the infant to infection. Choice B is incorrect as there is no evidence of inadequate circulation being a primary factor in infection predisposition in cleft lip cases. Choice C is incorrect because although ineffective feeding may lead to other issues, it is not the main reason for infection predisposition in infants with a cleft lip.
Question 2 of 5
What definitive diagnostic procedure does the nurse expect to be used to confirm the diagnosis of Hirschsprung disease in a 1-month-old infant?
Correct Answer: B
Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. This procedure reveals the absence of ganglion cells in the affected bowel segment, which is a hallmark of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for diagnosing Hirschsprung disease due to the risk of not accurately reaching the affected segment. Multiple saline enemas (Choice C) are not used to confirm the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a standard diagnostic procedure for Hirschsprung disease and does not provide the necessary information to confirm the absence of ganglion cells in the affected bowel segment.
Question 3 of 5
The instructor is educating a group of students about myelination in a child. Which statement by the students indicates that the teaching was successful?
Correct Answer: B
Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect because myelination continues beyond 4 years of age and into adolescence. Choice C is incorrect as myelination speeds up nerve impulses rather than slowing them down. Choice D is incorrect because myelination increases the specificity and efficiency of nerve impulses, making them more focused and precise.
Question 4 of 5
The school nurse is presenting a class to a group of students about common overuse disorders. Which disorder would the school nurse include?
Correct Answer: C
Rationale: Osgood-Schlatter disease is a common overuse injury that specifically affects the knee. It is characterized by inflammation of the patellar ligament at the tibial tuberosity due to repetitive strain on the growth plate during activities such as running and jumping. Dislocated radial head (Choice A) is not an overuse disorder but rather an injury usually seen in young children. Transient synovitis of the hip (Choice B) is an acute hip condition and not typically classified as an overuse disorder. Scoliosis (Choice D) is a condition characterized by an abnormal lateral curvature of the spine and is not considered an overuse disorder.
Question 5 of 5
A child is brought to the clinic after tripping over a rock. The child states, 'I twisted my ankle,' and is given a diagnosis of a sprain. What intervention is most important for the nurse to include in the discharge instructions for this child?
Correct Answer: A
Rationale: The correct answer is A. Applying ice in intervals helps to reduce swelling and pain in the first 24 hours after a sprain. This intervention is crucial in the initial management of a sprain to decrease inflammation and provide pain relief. Bed rest with the leg elevated for 36 hours (Choice B) is not recommended as prolonged immobilization can lead to stiffness and decreased range of motion. Allowing the child to take an NSAID for pain as prescribed (Choice C) is a supportive measure but not as essential as ice application in the acute phase. Using a compression dressing for 72 hours (Choice D) may assist in reducing swelling, but it is not as critical as the immediate application of ice to manage pain and inflammation effectively.
