Pediatric Practice Exam HESI

Correct Answer: D

Rationale: Severe joint pain is a classic symptom of rheumatic fever, resulting from inflammation of the joints. Rheumatic fever primarily affects the joints, heart, skin, and the central nervous system. Jaundice (Choice A) is not typically associated with rheumatic fever. Peeling skin on the hands and feet (Choice B) is more characteristic of conditions like Kawasaki disease. While high fever (Choice C) can be present in rheumatic fever, it is not as specific or characteristic as severe joint pain.

Correct Answer: C

Rationale: The correct answer is to look along the scalp line for white dots (nits) when checking for head lice. White dots/nits are the eggs of head lice and are commonly found attached to the hair shaft near the scalp. This method helps identify if head lice are present. Choice A is incorrect as itching alone may not be a definitive sign of head lice; it could be due to other reasons. Choice B is irrelevant as ear mites in dogs are not related to head lice infestation in humans. Choice D is also incorrect as observing between the fingers for red lines is not a method for checking head lice.

Correct Answer: C

Rationale: The correct supportive measure for the school nurse to use for a boy with hemophilia who fell on his arm during recess is to elevate the area above the level of the heart. Elevating the affected area helps reduce bleeding and swelling in a child with hemophilia until factor replacement therapy can be provided. Applying warm, moist compresses (Choice A) may worsen bleeding by dilating blood vessels. Applying pressure for at least 1 minute (Choice B) is not recommended for hemophilia as it can lead to increased bleeding. Beginning passive range-of-motion (Choice D) should be avoided as it can exacerbate bleeding and further injury in a child with hemophilia.

Correct Answer: C

Rationale: The correct nursing diagnosis would be 'Grieving related to the child's poor prognosis.' Trisomy 18 is associated with a poor prognosis, and families often experience feelings of grief and loss when dealing with such a diagnosis. The choice 'Interrupted family process' does not directly address the emotional response to the prognosis. 'Deficient knowledge' may be a concern but does not address the emotional aspect of dealing with a poor prognosis. 'Ineffective coping related to stress from providing care' focuses more on the caregiver's ability to cope rather than the family's response to the child's condition.

Correct Answer: B

Rationale: Using a soft toothbrush helps to prevent bleeding in a child with hemophilia.
