Pediatric HESI Practice Questions

Correct Answer: B

Rationale: The correct technique for opening the airway of an infant with no suspected neck injury is to tilt the head back without hyperextending the neck. This method helps to keep the airway open without risking injury to the infant's delicate neck structures. Choice A, lifting up the chin and hyperextending the neck, can potentially harm the infant's neck. Choice C, gently lifting the chin while maintaining slight flexion of the neck, is not as effective as tilting the head back. Choice D is incorrect as infants require a different approach compared to older children or adults due to their anatomical differences.

Correct Answer: A

Rationale: The correct action would be to notify the doctor immediately. Unrelenting pain despite medication can indicate compartment syndrome, which is a medical emergency requiring immediate attention. Applying ice, elevating the arm, or giving additional pain medication may not address the underlying cause of the unrelenting pain, which could be a sign of a serious complication like compartment syndrome. Prompt medical evaluation is crucial in this situation to prevent potential complications.

Correct Answer: B

Rationale: The priority nursing intervention for a 3-year-old child with Kawasaki disease is monitoring for coronary artery aneurysms. Kawasaki disease can lead to the development of coronary artery aneurysms, which are one of the most serious complications of the disease. Early detection and monitoring of coronary artery changes are essential for prompt intervention and prevention of adverse outcomes. Administering IV immunoglobulin is an important treatment for Kawasaki disease, but monitoring for coronary artery aneurysms takes precedence as it directly impacts the child's long-term prognosis. Encouraging fluid intake and providing nutritional support are important aspects of care but are not the priority when compared to monitoring for potential life-threatening complications.

Correct Answer: C

Rationale: In a child with a congenital cardiac malformation causing right-to-left shunting of blood, the nurse should expect an elevated hematocrit. This occurs because the body compensates for decreased oxygenation by producing more red blood cells. Proteinuria (Choice A) is not a typical clinical finding related to right-to-left shunting. Peripheral edema (Choice B) is more commonly associated with conditions causing volume overload, such as left-sided heart failure. Absence of pedal pulses (Choice D) is not directly related to right-to-left shunting but may be seen in conditions affecting peripheral circulation.

Correct Answer: D

Rationale: The varicella vaccine is specifically designed to prevent chickenpox. Measles, mumps, and rubella are prevented by different vaccines (MMR vaccine for measles, mumps, and rubella). Therefore, the correct answer is chickenpox (varicella). It is crucial for healthcare professionals to provide accurate information about vaccines to help ensure the health and well-being of individuals.
