A nurse is caring for a 7-year-old child who has acute glomerulonephritis. Which of the following findings is the priority for the nurse to report to the provider?

Choice A reason: Assessing vital signs every 4 hours is important, but it is not specific to the care of an infant post-cardiac catheterization. Vital signs should be monitored according to the infant's condition and hospital policy.

Choice B reason: Monitoring the color of the affected extremity is crucial after cardiac catheterization to ensure there is no compromise in blood flow, which could indicate a vascular injury or thrombosis at the catheterization site.

Choice C reason: Maintaining NPO (nothing by mouth) status for 8 hours may be necessary before the procedure, but post-catheterization care typically includes gradual reintroduction of fluids and then food as tolerated.

Choice D reason: Keeping the affected extremity flexed is not recommended post-cardiac catheterization. The limb should be kept straight to avoid bending at the catheterization site, which could lead to bleeding or clot formation.

Choice A reason: For individuals who are lactose intolerant, it is important to find alternative sources of calcium. Non-dairy sources such as fortified plant-based milks, leafy greens, and calcium-fortified foods can provide the necessary calcium without causing discomfort.

Choice B reason: Flavored yogurt often contains added sugars and may still have lactose, which can cause symptoms in those who are lactose intolerant. It's better to choose lactose-free options or plant-based alternatives.

Choice C reason: Lactose intolerance means that the body cannot effectively digest lactose found in milk, regardless of whether it is plain or chocolate. Therefore, it is not advisable to consume any milk that contains lactose.

Choice D reason: Drinking milk on an empty stomach can actually worsen symptoms for someone who is lactose intolerant. It is better to avoid milk or choose lactose-free alternatives.
