HESI Pediatrics Practice Exam

Correct Answer: C

Rationale: Implementing discipline and limit setting for infants and toddlers is primarily important as it provides them with a sense of security. This sense of security is crucial for their emotional and psychological development, helping them feel safe and supported as they explore the world around them. Choice A is incorrect because while developing social skills is important, the primary reason for discipline and limit setting in this context is to provide security. Choice B is incorrect as it does not address the main reason for implementing discipline and limit setting. Choice D is incorrect as the primary focus is not about dealing with authority at this early stage of development.

Correct Answer: A

Rationale: The ability to laugh readily and turn from back to side indicates the effectiveness of thyroid therapy and normal development in a 5-month-old. These behaviors suggest improved muscle tone and motor skills, which are positive outcomes of thyroid hormone replacement therapy for hypothyroidism. Choices B, C, and D describe developmental milestones that are not specific indicators of the effectiveness of thyroid therapy in treating hypothyroidism in a 5-month-old.

Correct Answer: C

Rationale: In a child with pneumonia who is breathing rapidly, the priority action for the nurse is to start the child on oxygen therapy. This intervention is essential to ensure adequate oxygenation, which is crucial in managing respiratory distress and preventing complications associated with hypoxia. Administering antipyretic medication (Choice A) may help reduce the fever but does not address the immediate need for oxygen therapy. Obtaining a chest X-ray (Choice B) is important for diagnosis but providing oxygen is more urgent. Notifying the healthcare provider (Choice D) can be done after initiating oxygen therapy to update on the patient's condition.

Correct Answer: A

Rationale: In a pediatric patient with severe dehydration and signs of compromised hemodynamics such as tachycardia (heart rate of 150 bpm) and hypotension (blood pressure of 90/50 mm Hg), the priority intervention is to administer IV fluids as prescribed. Immediate fluid resuscitation is essential to restore hydration, improve perfusion, and stabilize the child's vital signs. While it's important to monitor urine output, initiating fluid resuscitation takes precedence in this situation. Notifying the healthcare provider can cause a delay in critical intervention, and waiting to reassess vital signs in 30 minutes can be detrimental in a child with severe dehydration and compromised hemodynamics.

Correct Answer: A

Rationale: Frequent swallowing post-tonsillectomy may indicate bleeding. Inspecting the posterior oropharynx is essential to assess for any signs of bleeding, such as fresh blood or clots, which may necessitate immediate intervention. Option B is incorrect as teeth clenching or grinding is not directly related to the observation of frequent swallowing in this scenario. Option C is incorrect because stimulating the gag reflex is not necessary at this point and may be uncomfortable for the child. Option D is incorrect as evaluating a change in voice tone is not relevant to the situation of observing frequent swallowing.
