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: D

Rationale: The correct answer is D: "These responses are replaced by voluntary activity at about five months of age." The grasp reflex and startle reflex (Moro reflex) are normal in newborns but typically disappear as the infant's nervous system matures and voluntary control develops. Choice A is incorrect because checking the responses before deciding a course of action does not address the developmental milestone related to the reflexes. Choice B is incorrect as it jumps to a conclusion of developmental delay without considering the normal developmental process. Choice C is incorrect as additional sensory stimulation is not necessary for the return of these reflexes, as they are expected to naturally diminish as part of normal development.

Correct Answer: B

Rationale: The correct answer is to offer a pacifier to the infant before administering tube feeding. Offering a pacifier helps stimulate the sucking reflex, preparing the infant for feeding and promoting digestion and comfort. Irrigating the tube with water (Choice A) is not typically the first action before tube feeding and may not be necessary. Slowly instilling formula (Choice C) should only be done after the infant is prepared for feeding. Placing the infant in the Trendelenburg position (Choice D) is not necessary and may not be recommended for tube feeding.

Correct Answer: D

Rationale: The correct nursing intervention essential before surgery for an infant with Hirschsprung disease is maintaining NPO (nothing by mouth) status. This is important to prevent aspiration during and after the surgical procedure. Administering antibiotics (Choice A) may be necessary in some cases but is not the priority intervention before surgery. Ensuring bowel rest (Choice B) is not directly related to preparing for surgery and may not be the most critical intervention. Performing regular enemas (Choice C) is not recommended before surgery for Hirschsprung disease as it can aggravate the condition.

Correct Answer: B

Rationale: The correct answer is B: 'Dry the area between your toes thoroughly.' When educating an adolescent about tinea pedis, emphasis should be placed on keeping the feet dry, especially between the toes, to minimize the risk of fungal infection. Choice A is incorrect as keeping the feet moist can exacerbate the condition. Choice C is incorrect because nylon or synthetic socks can trap moisture, promoting fungal growth. Choice D is incorrect as walking barefoot in locker rooms increases the risk of contracting tinea pedis from contaminated surfaces.
