Pediatric HESI 2024

Correct Answer: D

Rationale: A common clinical manifestation of bacterial meningitis is a positive Kernig sign, which indicates meningeal irritation. Kernig sign is elicited when the leg is bent at the hip and knee at 90-degree angles, and pain and resistance are felt with extension at the knee due to inflamed meninges. Options A, B, and C are not typically associated with bacterial meningitis. A rash is more commonly seen in viral illnesses, photophobia can be present but is not specific to bacterial meningitis, and jaundice is not a typical clinical manifestation of this condition.

Correct Answer: B

Rationale: The correct answer is B: Steroids. Children receiving steroids should not receive the varicella vaccine as it can increase the risk of severe infection due to the immunosuppressive effects of steroids. Insulin (Choice A), antibiotics (Choice C), and anticonvulsants (Choice D) do not interact with the varicella vaccine in the same way as steroids, and therefore, they are not contraindicated.

Correct Answer: B

Rationale: The correct first action before administering tube feeding to an infant is to offer a pacifier. Providing a pacifier stimulates the sucking reflex, aiding in digestion and providing comfort to the infant. Irrigating the tube with water (Choice A) is not typically the initial step and could potentially introduce unnecessary fluid into the infant's system. Slowly instilling formula (Choice C) should only be done after ensuring the tube is appropriately placed. Placing the infant in the Trendelenburg position (Choice D) is not necessary for tube feeding and could pose risks such as aspiration.

Correct Answer: C

Rationale: The correct answer is C: Maintain standard and contact precautions. RSV is highly contagious, primarily spread through respiratory secretions. Therefore, it is crucial to implement infection control measures such as standard and contact precautions to prevent the spread of the virus to other patients, staff, and visitors. Choice A is incorrect because warmth and dryness are not specific interventions for RSV; the focus should be on infection control. Choice B may increase the risk of exposing others to RSV, so limiting visitors is recommended. Choice D is unnecessary because RSV is a viral infection, and antibiotics are not effective against viruses.

Correct Answer: D

Rationale: The classification system of congenital heart defects into acyanotic or cyanotic defects is problematic because children with acyanotic heart defects may develop cyanosis, complicating the differentiation. Cyanosis can occur in some acyanotic defects due to various reasons such as right-to-left shunting or decreased pulmonary blood flow, making the classification based solely on cyanosis misleading. Choice A is incorrect because while the classification may involve hemodynamics, the main issue lies in the potential for acyanotic defects to develop cyanosis. Choice B is incorrect as the ease of identifying children with cyanotic defects does not address the main problem with the classification system. Choice C is also incorrect as the presence of cyanosis is not the only factor determining the classification's validity.
