Question 1 of 5
The nurse is teaching 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 as myelination continues into adolescence and beyond, not just during childhood. Choice C is incorrect because myelination actually increases the speed of nerve impulses rather than decreasing it. Choice D is incorrect as myelination enhances the specificity of nerve impulses, making them more efficient and precise rather than less specific.
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 intervention for a sprained ankle is to apply ice for 20 minutes every hour for the first 24 hours, then remove for 60 minutes to prevent tissue damage. This regimen helps reduce swelling and pain. Bed rest with the leg elevated for an extended period (36 hours) may lead to stiffness and decreased range of motion. While NSAIDs can be used for pain, they may not be necessary if pain is manageable with ice and rest. Using a compression dressing for 72 hours continuously may impede proper circulation and delay healing by restricting blood flow.
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 the most crucial intervention when administering IV fluids to a dehydrated infant. This ensures that the correct amount of fluids is being delivered to the infant at the appropriate rate. While continuing the prescribed flow rate (Choice A) may be important, it does not allow for real-time adjustments that may be necessary during the infusion. Calculating the total necessary intake (Choice C) should have been determined before initiating IV therapy. Maintaining the fluid at body temperature (Choice D) is important for patient comfort but is not as critical as ensuring the proper administration of fluids.
Question 4 of 5
A child with a cardiac malformation associated with left-to-right shunting. What does this type of congenital disorder lead to primarily?
Correct Answer: D
Rationale: Left-to-right shunting in a cardiac malformation results in increased blood flow to the lungs. This increased blood flow can lead to pulmonary hypertension and heart failure if left untreated. Elevated hematocrit (Choice A) is not a characteristic directly associated with left-to-right shunting. Severe growth retardation (Choice B) is not a typical manifestation of this type of congenital disorder. Clubbing of the fingers and toes (Choice C) is more commonly seen in conditions like chronic respiratory or cardiac diseases, not specifically with left-to-right shunting and associated cardiac malformations.
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: When managing a child with partial thickness burns over the upper body areas, the priority action during the primary survey is to assess for a patent airway. This step is crucial as burns in this region can lead to airway compromise, potentially causing rapid deterioration in the child's condition. Checking for a patent airway ensures that the child can breathe adequately, which is essential for oxygenation and ventilation. Inspecting the child's skin color (Choice A) is an important assessment but should follow ensuring a patent airway. Observing for symmetric breathing (Choice C) is relevant, but the immediate focus should be on securing the airway. Palpating the child's pulse (Choice D) is also a vital assessment, but in this scenario, the priority is to assess and maintain a clear airway to support respiratory function and oxygen delivery.
