HESI Pediatrics Practice Exam

Correct Answer: B

Rationale: A cool, pale, and blanched foot is indicative of arterial obstruction, leading to poor blood flow. This finding requires immediate intervention to prevent further complications such as tissue damage or necrosis. Monitoring for signs of arterial compromise, such as color changes, temperature, and capillary refill, is crucial in detecting and managing vascular complications post-cardiac catheterization. Choices A, C, and D do not directly indicate arterial obstruction. While a decreasing blood pressure and rapid, irregular pulse may suggest compromise, these findings are more nonspecific. A weaker pulse distal to the femoral artery indicates reduced perfusion but not necessarily arterial obstruction. Finally, a damp, oozing pressure dressing suggests a dressing issue rather than arterial obstruction.

Correct Answer: D

Rationale: The correct answer is D. Children with celiac disease must strictly adhere to a gluten-free diet. Even small amounts of gluten can cause harm by triggering an immune response that damages the intestines. It is crucial for parents to understand that allowing their child to have small amounts of gluten occasionally is not safe and can lead to complications. Therefore, further teaching is needed to emphasize the importance of complete avoidance of gluten-containing foods for a child with celiac disease. Choices A, B, and C demonstrate understanding of the need to avoid gluten-containing foods and hidden sources of gluten, which are essential in managing celiac disease. Choice D is incorrect as it suggests a lax approach to the child's diet, which can be harmful in the case of celiac disease.

Correct Answer: A

Rationale: Pyloric stenosis leads to obstruction at the outlet of the stomach, causing frequent vomiting and loss of stomach acids. This results in a loss of hydrochloric acid and hydrogen ions, leading to metabolic alkalosis due to an increase in serum bicarbonate levels. Therefore, the correct answer is metabolic alkalosis. Choice B, respiratory acidosis, is incorrect as it is not typically associated with pyloric stenosis. Choice C, metabolic acidosis, is incorrect because the loss of stomach acids in pyloric stenosis leads to metabolic alkalosis, not acidosis. Choice D, respiratory alkalosis, is also incorrect as it is not the usual consequence of pyloric stenosis.

Correct Answer: D

Rationale: The nurse should educate the mother that giving pain medication around the clock helps maintain a consistent level of pain control, preventing severe pain episodes and improving the child's quality of life. It is essential to manage pain proactively rather than waiting for the child to be in severe pain before administering medication. Choices A, B, and C do not address the importance of proactive pain management and maintaining a consistent level of pain control. Encouraging rest, quiet activities, or hot baths as distractions or alternatives may not provide adequate pain relief for the child with juvenile arthritis, and they do not address the underlying issue of effective pain management.

Correct Answer: A

Rationale: In a child who has fallen and hit their head, presenting with drowsiness and headache, the priority action for the nurse is to perform a full neurological assessment. This is crucial to evaluate the extent of the head injury and monitor for signs of increased intracranial pressure, which could indicate a more severe traumatic brain injury. Administering pain medication or allowing the child to rest quietly are not appropriate initial actions without first assessing the neurological status. Checking the child's immunization status is important for overall health but is not the priority in this acute situation.
