HESI Pediatrics Practice Exam

Correct Answer: B

Rationale: The correct answer is B: 'Opens mouth when food comes her way.' This behavior indicates readiness to start trying solid foods. Infants should be introduced to solid foods based on developmental cues, such as showing an interest in food and the ability to accept it. Choices A, C, and D are not indicative of readiness for solid foods. Stopping rooting when hungry is a reflex that may persist beyond the readiness for solids. Awakening for nighttime feedings is a normal behavior for a 4-month-old, and transitioning from a bottle to a cup is a later developmental milestone.

Correct Answer: B

Rationale: The correct answer is B: 'Decreased heart rate.' Propranolol is a beta-blocker commonly used to manage symptoms of hyperthyroidism, including tachycardia. Monitoring for a decreased heart rate is important as it indicates the drug's therapeutic response in controlling the elevated heart rate associated with Graves' disease. Choices A, C, and D are incorrect because weight gain, reduced headaches, and diminished fatigue are not typical therapeutic responses to propranolol in the context of managing Graves' disease.

Correct Answer: D

Rationale: The best response for a two-year-old boy who begins to cry when the mother starts to leave is to wave bye-bye to mommy. This action helps the child understand that the separation is temporary and gives him a sense of closure. Choice A is the correct answer. Choice B is incorrect as it generalizes the behavior of two-year-olds. Choice C may invalidate the child's feelings by telling him to 'be a big boy' instead of acknowledging his emotions and providing comfort.

Correct Answer: B

Rationale: Introducing solid foods when the child opens their mouth for food is important to ensure readiness for solids. This behavior indicates the infant's interest and readiness for new textures and flavors, promoting safe and successful introduction to solid foods. The other choices are not indicative of the infant's readiness for solid foods: A - stopping rooting is a reflex action, C - awakening for nighttime feedings is a normal behavior, and D - transitioning from a bottle to a cup is a developmental milestone unrelated to solid food introduction.

Correct Answer: B

Rationale: When screening a 5-year-old for strabismus, directing the child through the six cardinal positions of gaze is the most appropriate action. This method helps the nurse to assess eye alignment, which is crucial in identifying any misalignment that may indicate strabismus. Choices A, C, and D are incorrect. Having the child identify colored patterns on polychromatic cards is more related to visual acuity testing rather than strabismus screening. Inspecting the child for the setting sun sign is not a standard method for strabismus screening. Observing the child for blank, sunken eyes is not specific to strabismus assessment.
