HESI Pediatrics Quizlet Questions
Question 1 of 5
The instructor is educating a group of students about myelination in a child. Which statement by the students indicates that the teaching was successful?
Correct Answer: B
Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect because myelination continues beyond 4 years of age and into adolescence. Choice C is incorrect as myelination speeds up nerve impulses rather than slowing them down. Choice D is incorrect because myelination increases the specificity and efficiency of nerve impulses, making them more focused and precise.
Question 2 of 5
A child is brought to the clinic after tripping over a rock. The child states, 'I twisted my ankle,' and is given a diagnosis of a sprain. What intervention is most important for the nurse to include in the discharge instructions for this child?
Correct Answer: A
Rationale: The correct answer is A. Applying ice in intervals helps to reduce swelling and pain in the first 24 hours after a sprain. This intervention is crucial in the initial management of a sprain to decrease inflammation and provide pain relief. Bed rest with the leg elevated for 36 hours (Choice B) is not recommended as prolonged immobilization can lead to stiffness and decreased range of motion. Allowing the child to take an NSAID for pain as prescribed (Choice C) is a supportive measure but not as essential as ice application in the acute phase. Using a compression dressing for 72 hours (Choice D) may assist in reducing swelling, but it is not as critical as the immediate application of ice to manage pain and inflammation effectively.
Question 3 of 5
When administering IV fluids to a dehydrated infant, what intervention is most important at this time?
Correct Answer: B
Rationale: Monitoring the intravenous drop rate is crucial when administering IV fluids to ensure that the correct amount of fluids is delivered to the dehydrated infant. Choice A assumes the initial rate is correct without ongoing assessment. Choice C, while important, does not address the immediate need for monitoring the infusion rate. Choice D, maintaining the fluid at body temperature, is essential for comfort but is not as critical as ensuring the correct fluid delivery rate. By monitoring the intravenous drop rate, healthcare providers can adjust the flow as needed to prevent overhydration or underhydration, helping to manage the infant's fluid balance effectively.
Question 4 of 5
A child with a cardiac malformation associated with left-to-right shunting is being cared for by a nurse. What does the nurse consider to be the major characteristic of this type of congenital disorder?
Correct Answer: D
Rationale: The major characteristic of a cardiac malformation associated with left-to-right shunting is increased blood flow to the lungs. This increased flow can lead to pulmonary hypertension and heart failure if left untreated. Elevated hematocrit (Choice A) is not a typical characteristic of this condition. Severe growth retardation (Choice B) is not directly associated with left-to-right shunting. Clubbing of the fingers and toes (Choice C) is more commonly seen in conditions involving chronic hypoxia.
Question 5 of 5
During a primary survey of a child with partial thickness burns over the upper body areas, what action should the nurse take first?
Correct Answer: B
Rationale: The correct answer is B: Assess for a patent airway. When dealing with a child who has sustained partial thickness burns, the priority is ensuring a patent airway due to the risk of respiratory compromise. Checking the child's skin color (choice A) may be important but is secondary to assessing the airway. While observing for symmetric breathing (choice C) is crucial, assessing the airway takes precedence in this situation. Palpating the child's pulse (choice D) is not the initial priority when managing burns and potential airway compromise.
