Pediatric Practice Exam HESI

Correct Answer: D

Rationale: The correct answer is D, severe joint pain. Rheumatic fever commonly presents with severe joint pain due to joint inflammation. Jaundice (choice A) is not typically associated with rheumatic fever. Peeling skin on the hands and feet (choice B) is more indicative of conditions like Kawasaki disease. While a high fever (choice C) can be present, it is not as specific to rheumatic fever as severe joint pain. Severe joint pain, along with other criteria like carditis, subcutaneous nodules, erythema marginatum, and Sydenham chorea, are major criteria used in the diagnosis of rheumatic fever.

Correct Answer: A

Rationale: The priority nursing intervention for a child with leukemia receiving chemotherapy is monitoring for signs of infection. Chemotherapy can suppress the immune system, increasing the risk of infections. Detecting and managing infections promptly is crucial to prevent complications and improve outcomes. Providing nutritional support is important, but infection prevention takes precedence due to the immediate threat it poses to the child's health. Monitoring for signs of bleeding is relevant in leukemia due to decreased platelet count, but infection surveillance is more critical. Monitoring for signs of pain is essential, but addressing infections promptly is the priority to prevent further deterioration in the child's condition.

Correct Answer: D

Rationale: The correct answer is to test the temperature of water before bathing. This is crucial in preventing burns, which is a significant risk for infants due to their sensitive skin. Infants have delicate skin that can be easily burned by water that is too hot. Removing small objects from the floor (Choice A) is important to prevent choking hazards but not directly related to burns. Covering electric outlets with safety plugs (Choice B) is essential to prevent electrocution but does not address the risk of burns specifically. Removing toxic substances from low areas (Choice C) is necessary to prevent poisoning but is not directly related to burns. Therefore, the priority in this scenario is to prevent burns by ensuring the water temperature is safe for the infant.

Correct Answer: C

Rationale: After eating, it is beneficial to place a child with GERD in a semi-Fowler's position. This position helps prevent reflux by keeping the child's head elevated above the stomach, reducing the chances of gastric contents flowing back into the esophagus. Placing the child supine (lying flat on their back) can worsen reflux symptoms by allowing gravity to work against the natural flow of gastric contents. Prone position (lying on the stomach) is not recommended due to the increased risk of aspiration. Trendelenburg position (feet elevated above head) is also inappropriate as it can lead to increased pressure on the abdomen, potentially worsening reflux symptoms.

Correct Answer: A

Rationale: In coarctation of the aorta, there is narrowing of the aorta leading to decreased blood flow distal to the constriction. This results in a weak or delayed femoral pulse and a relatively weaker radial pulse compared to the femoral pulse. An irregular heartbeat (choice B) is not a typical finding in coarctation of the aorta. A bounding femoral pulse (choice C) would not be expected due to the decreased blood flow beyond the constriction. An elevated radial blood pressure (choice D) is not a common characteristic of coarctation of the aorta; instead, blood pressure may be higher in the upper extremities compared to the lower extremities due to the constriction.
