HESI Pediatrics Quizlet Questions
Question 1 of 5
What factor predisposes the urinary tract to infection in children?
Correct Answer: B
Rationale: The short urethra in young girls is a significant factor that predisposes them to urinary tract infections. Girls have a shorter urethra than boys, making it easier for bacteria to travel up the urinary tract, leading to infections. Increased fluid intake (Choice A) is actually a preventive measure as it helps flush out bacteria from the urinary tract. Prostatic secretions in males (Choice C) do not predispose the urinary tract to infection in children. Frequent emptying of the bladder (Choice D) is also a good practice to prevent urinary tract infections by reducing the chances of bacterial growth in the urinary tract.
Question 2 of 5
While waiting for the administration of air pressure to reduce the intussusception, the boy passes a normal brown stool. Which nursing action is the most appropriate for the nurse to take?
Correct Answer: A
Rationale: The correct answer is to notify the practitioner. The passage of a normal brown stool in a child with intussusception could indicate spontaneous reduction of the intussusception. It is crucial to inform the practitioner immediately so that they can reassess the situation and determine the next steps, which may include adjusting the planned intervention. Measuring abdominal girth (choice B) may be important in assessing for abdominal distension but is not the most immediate action required in this scenario. Auscultating for bowel sounds (choice C) is a routine nursing assessment but does not take precedence over notifying the practitioner in this critical situation. Taking vital signs, including blood pressure (choice D), is also important but notifying the practitioner is more urgent to address the unexpected change in the patient's condition.
Question 3 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 4 of 5
After an infant has had corrective surgery for hypertrophic pyloric stenosis (HPS), what should the nurse teach a parent to do immediately after a feeding to limit vomiting?
Correct Answer: B
Rationale: Correct Answer: B. Placing the infant in an infant seat is essential after feeding to help keep the head elevated and reduce the risk of vomiting. This position helps prevent regurgitation of formula or milk. Rocking the infant (Choice A) is incorrect because it may exacerbate vomiting due to the movement. Placing the infant flat on the right side (Choice C) is incorrect as it does not promote proper digestion and can increase the risk of vomiting. Keeping the infant awake with sensory stimulation (Choice D) is incorrect as it does not directly address the physiological need to reduce vomiting after feeding.
Question 5 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.
