Correct Answer: A

Rationale: When a child expresses fear or anxiety about receiving a vaccination, it is essential for the healthcare provider to provide honest and reassuring information. Choice A acknowledges the potential for some discomfort but also reassures the child that it will be over quickly. This response validates the child's feelings while also preparing them for the procedure. Choices B, C, and D either provide false reassurance, dismiss the child's feelings, or suggest avoidance, which are not appropriate responses in this situation.

Correct Answer: A

Rationale: In infants, laughing readily and turning from back to side are indicative of normal development. These behaviors indicate that the thyroid therapy is effective, as they suggest the baby is achieving age-appropriate milestones. A 5-month-old infant should be able to laugh readily and turn from back to side, showing progress in motor and social development. Choices B, C, and D describe behaviors that are not specific to the expected developmental milestones of a 5-month-old. Strong Moro and tonic neck reflexes, clenched fists, and limited ability to lift the chest when lying on the abdomen are not necessarily indicative of the effectiveness of thyroid therapy for hypothyroidism.

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: Corrected Question: The healthcare provider plans to screen only the highest risk children for scoliosis. Which group of children should the healthcare provider screen first? Girls between ages 10 and 14 are at the highest risk for scoliosis and should be screened first as they have a higher incidence of developing scoliosis during their adolescent growth spurt. Early detection and intervention can help prevent further complications associated with scoliosis. Boys between ages 10 and 14 (choice B) are not at the highest risk compared to girls in the same age group. Boys and girls between 12 and 14 (choice C) are at a lower risk compared to girls between ages 10 and 14. Boys and girls between 8 and 12 (choice D) are at a lower risk group compared to girls between ages 10 and 14.
