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 predisposes them to urinary tract infections. In young girls, the proximity of the urethra to the anus and the shorter urethra compared to boys make it easier for bacteria to travel up the urinary tract, increasing the risk of infection. Increased fluid intake and frequent emptying of the bladder are actually helpful in preventing urinary tract infections by flushing out bacteria. Prostatic secretions in males are not a factor in predisposing the urinary tract to infection in children.
Question 2 of 5
The nurse is caring for a boy with probable intussusception. He had diarrhea before admission, but while waiting for the administration of air pressure to reduce the intussusception, he passes a normal brown stool. Which nursing action is the most appropriate?
Correct Answer: A
Rationale: The passage of a normal brown stool in a child with intussusception could indicate spontaneous reduction of the intussusception. This change in the patient's condition is significant, requiring prompt notification of the practitioner for further evaluation and management. While measuring abdominal girth (Choice B) is important for assessing abdominal distention, it is not the priority when a potential spontaneous reduction may have occurred. Auscultating for bowel sounds (Choice C) and taking vital signs, including blood pressure (Choice D), are routine nursing assessments but do not address the immediate need to inform the practitioner of a possible change in the patient's condition that necessitates urgent attention.
Question 3 of 5
Why does a cleft lip predispose an infant to infection, concerning a nurse caring for the infant?
Correct Answer: D
Rationale: Mouth breathing due to a cleft lip can dry the mucous membranes, increasing their susceptibility to infection. While waste product accumulation (Choice A) and inadequate circulation (Choice B) may contribute to complications, they are not directly related to infection in this context. Inadequate nutrition (Choice C) may affect overall health but is not the primary reason for infection predisposition in this case.
Question 4 of 5
After 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: After corrective surgery for hypertrophic pyloric stenosis (HPS), placing the infant in an infant seat is the correct action to take immediately after feeding to limit vomiting. This position helps keep the head elevated, reducing the risk of vomiting. Rocking the infant (Choice A) may agitate the stomach and increase the likelihood of vomiting. Placing the infant flat on the right side (Choice C) is not recommended as it does not encourage proper digestion and may increase the risk of vomiting. Keeping the infant awake with sensory stimulation (Choice D) does not address the positioning concern related to vomiting in this specific post-operative scenario.
Question 5 of 5
How is the diagnosis of Hirschsprung disease confirmed in a 1-month-old infant admitted to the pediatric unit?
Correct Answer: B
Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. It confirms the absence of ganglion cells in the affected bowel segment, which is characteristic of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for confirmation as it may not provide a definitive result. Multiple saline enemas (Choice C) are utilized in the treatment of meconium ileus, a complication of cystic fibrosis, and not in the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a diagnostic tool for Hirschsprung disease; it is commonly used for gastrointestinal decompression or feeding purposes but does not confirm the diagnosis.
