Pediatric Practice Exam HESI

Correct Answer: D

Rationale: Full-thickness burns, also known as third-degree burns, are characterized by a leathery, dry appearance with numbness due to nerve damage. This type of burn extends through all layers of the skin, affecting nerve endings. Choice A describes characteristics of superficial partial-thickness burns, which involve the epidermis and part of the dermis. Choice B describes characteristics of superficial burns, or first-degree burns, which only affect the epidermis. Choice C describes characteristics of superficial to mid-dermal burns, also known as second-degree burns, which involve the epidermis and part of the dermis but do not extend through all skin layers. Therefore, the correct answer is D.

Correct Answer: A

Rationale: The correct answer is A: Sterility. Mumps can lead to serious complications such as sterility, especially in adolescent males. Vaccination is essential to prevent this potential outcome. Hypopituitarism (Choice B) is not a typical complication of mumps. Choices C and D, decrease in libido and decrease in androgens, are not directly associated with mumps complications, particularly in the context of adolescents.

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: B

Rationale: The priority nursing intervention for a 4-year-old child admitted with bacterial pneumonia is administering antibiotics. Antibiotics are essential to treat the infection, prevent its spread, and avoid potential complications. Administering antipyretics (Choice A) may help reduce fever but does not address the underlying cause of pneumonia, which is bacterial in this case. Monitoring fluid intake (Choice C) is important to maintain hydration but does not directly treat the infection. Providing nutritional support (Choice D) is crucial for overall health, but the immediate priority is to address the bacterial infection with antibiotics to prevent further complications and promote recovery.

Correct Answer: B

Rationale: Choanal atresia is a congenital condition that presents with a blockage in the nasal passages at the junction of the nasal cavity and the nasopharynx. To assess and confirm the diagnosis of choanal atresia, the nurse should focus on assessing the nasopharynx. Choices A, C, and D are incorrect as choanal atresia specifically involves a blockage in the nasal passages, not the rectum, intestinal tract, or laryngopharynx. By assessing the nasopharynx, the severity of the obstruction can be determined, aiding in planning appropriate interventions for the newborn.
