HESI Pediatrics Practice Exam

Correct Answer: D

Rationale: The best response for a two-year-old boy who begins to cry when the mother starts to leave is to wave bye-bye to mommy. This action helps the child understand that the separation is temporary and gives him a sense of closure. Choice A is the correct answer. Choice B is incorrect as it generalizes the behavior of two-year-olds. Choice C may invalidate the child's feelings by telling him to 'be a big boy' instead of acknowledging his emotions and providing comfort.

Correct Answer: B

Rationale: In this scenario, the child's symptoms of fever, rash, and swollen joints following an untreated sore throat two weeks ago are indicative of rheumatic fever. Rheumatic fever can develop as a complication of untreated streptococcal infections, leading to systemic inflammation and affecting various organs, including the joints. This condition manifests with symptoms such as fever, rash, and swollen joints, aligning with the child's presentation in this case. Scarlet fever typically presents with a sandpapery rash and strawberry tongue but does not involve joint inflammation. Kawasaki disease presents with fever, rash, and mucous membrane changes but does not typically involve joint swelling. Juvenile rheumatoid arthritis can cause joint swelling but is not directly linked to a recent untreated sore throat.

Correct Answer: A

Rationale: In a child with acute glomerulonephritis, hypertension is the most concerning assessment finding as it can indicate worsening renal function. Hypertension is a common complication of glomerulonephritis and can lead to further kidney damage if not managed promptly. Monitoring and controlling blood pressure is crucial in these cases to prevent complications and preserve renal function. Gross hematuria, proteinuria, and periorbital edema are also common findings in acute glomerulonephritis but hypertension poses a higher risk for renal damage if left uncontrolled.

Correct Answer: D

Rationale: In this scenario, the 12-year-old male with a heart rate of 135 beats/minute, respirations of 20 breaths/minute, and blood pressure of 90/60 after falling during a skateboarding trick exhibits signs of shock. Weak and rapid peripheral pulses are concerning as they may indicate decreased cardiac output and tissue perfusion, which are signs of shock. This finding should be reported to the healthcare provider immediately for further evaluation and intervention to prevent potential complications. The other choices are less urgent. Complaints of back soreness (choice A) could be related to musculoskeletal injury. Capillary refill less than 2 seconds (choice B) is within the normal range, indicating adequate peripheral perfusion. A blood pressure of 94/68 (choice C) is slightly higher than the initial reading and may be compensatory in response to the fall and shock state.

Correct Answer: C

Rationale: In a child with pneumonia who is breathing rapidly, the priority action for the nurse is to start the child on oxygen therapy. This intervention is essential to ensure adequate oxygenation, which is crucial in managing respiratory distress and preventing complications associated with hypoxia. Administering antipyretic medication (Choice A) may help reduce the fever but does not address the immediate need for oxygen therapy. Obtaining a chest X-ray (Choice B) is important for diagnosis but providing oxygen is more urgent. Notifying the healthcare provider (Choice D) can be done after initiating oxygen therapy to update on the patient's condition.
