HESI Pediatrics Quizlet

Correct Answer: B

Rationale: Monitoring the intravenous drop rate is crucial when administering IV fluids to ensure that the correct amount of fluids is delivered to the dehydrated infant. Choice A assumes the initial rate is correct without ongoing assessment. Choice C, while important, does not address the immediate need for monitoring the infusion rate. Choice D, maintaining the fluid at body temperature, is essential for comfort but is not as critical as ensuring the correct fluid delivery rate. By monitoring the intravenous drop rate, healthcare providers can adjust the flow as needed to prevent overhydration or underhydration, helping to manage the infant's fluid balance effectively.

Correct Answer: B

Rationale: Encouraging deep breathing exercises is important preoperative teaching for a child scheduled for a tonsillectomy. Deep breathing exercises can help the child relax and reduce anxiety, which is beneficial before the procedure. Explaining the procedure in detail might be overwhelming for a 4-year-old, whereas encouraging deep breathing exercises can be more beneficial in promoting relaxation and preparing the child. Discussing the importance of hydration is crucial for postoperative care but may not be the priority for preoperative teaching. Using play therapy can help prepare the child, but encouraging deep breathing exercises is more directly related to relaxation and preparation for the procedure.

Correct Answer: B

Rationale: The most appropriate response in this situation is to ask for more specific information related to the developmental delays. By seeking additional details, the nurse can better understand the child's needs and provide tailored guidance and support to the parent. Praising the parent (Choice A) before fully grasping the situation may not be beneficial. Advising the parent to involve the healthcare provider in selecting a program (Choice C) is premature without a comprehensive understanding of the child's developmental delays. Explaining that the delays might resolve on their own (Choice D) is inappropriate as it dismisses the parent's concerns and the necessity for timely and appropriate interventions.

Correct Answer: A

Rationale: The correct answer is Varicella (chickenpox), choice A. Varicella can lead to the complication of encephalitis, which is the inflammation of the brain. Scarlet fever (choice B) is caused by Group A Streptococcus bacteria and does not typically lead to encephalitis. Poliomyelitis (choice C) is a viral infection that affects the nervous system but does not directly cause encephalitis. Whooping cough (choice D), also known as pertussis, primarily affects the respiratory system and does not commonly result in encephalitis.

Correct Answer: D

Rationale: The correct answer is D: surgical removal of the affected section of bowel. Hirschsprung disease is characterized by a segment of the colon lacking nerve cells, leading to obstruction. The definitive treatment involves surgically removing the affected segment, followed by a pull-through procedure to restore normal bowel continuity. Daily enemas (choice A) are not the primary treatment for Hirschsprung disease. While dietary adjustments may be advised, a low-fiber diet (choice B) alone is not curative for this condition. A permanent colostomy (choice C) is considered a last resort if surgical interventions fail or in severe cases, but it is not the initial therapeutic approach for managing Hirschsprung disease.
