HESI Pediatrics Practice Exam

Correct Answer: D

Rationale: The correct answer is D. Placing the child in a supine position to begin percussion is incorrect for chest physiotherapy (CPT). This position is not effective for CPT as it may lead to improper drainage of secretions. The child should be in an appropriate sitting or slightly reclined position to ensure proper lung drainage during CPT. Choices A, B, and C are all appropriate actions for chest physiotherapy. Performing CPT when the child awakens helps in clearing secretions, using a cupped hand during percussion is a proper technique to promote secretion movement, and administering a bronchodilator before CPT can help open up the airways for better clearance.

Correct Answer: B

Rationale: The correct answer is B: 'I will give my baby iron-fortified cereal.' Iron-fortified cereal is an excellent source of iron for infants, aiding in the prevention of iron deficiency anemia. Choice A is incorrect as whole cow's milk should not be introduced until the child is at least 12 months old to prevent iron deficiency. Choice C is incorrect because giving fruit juice between meals can interfere with iron absorption. Choice D is incorrect as giving water with meals can decrease nutrient intake. Therefore, the best choice to prevent iron deficiency anemia in a 9-month-old infant is to give them iron-fortified cereal.

Correct Answer: B

Rationale: The correct answer is B: 'Decreased heart rate.' Propranolol is a beta-blocker commonly used to manage symptoms of hyperthyroidism, including tachycardia. Monitoring for a decreased heart rate is important as it indicates the drug's therapeutic response in controlling the elevated heart rate associated with Graves' disease. Choices A, C, and D are incorrect because weight gain, reduced headaches, and diminished fatigue are not typical therapeutic responses to propranolol in the context of managing Graves' disease.

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.
