Correct Answer is B
Explanation
Choice A rationale
Diet cola, although refreshing, contains caffeine which can contribute to dehydration. For adolescents with sickle cell anemia, hydration is crucial to prevent sickle cell crises. Moreover, sodas generally offer no nutritional benefits.
Choice B rationale
Lemonade is a better choice as it is hydrating and provides fluids without caffeine. Proper hydration is vital for sickle cell patients to maintain blood volume and prevent the sickling of red blood cells. Additionally, lemonade can supply essential electrolytes.
Choice C rationale
Ice tea, similar to diet cola, contains caffeine which can exacerbate dehydration. Hydration is key for individuals with sickle cell anemia to avoid complications and maintain adequate blood flow.
Choice D rationale
Milkshake, while providing hydration, is high in fat and sugar, which can be counterproductive. It also lacks the electrolytes present in lemonade which are beneficial for maintaining fluid balance in the body.
Correct Answer is C
Explanation
Choice A rationale
Gathering supplies for an IV infusion is essential in many cases but not the priority here. Measuring abdominal circumference helps determine if there is abdominal distention indicating a possible blockage, which could suggest a condition like Hirschsprung's disease. Early detection and appropriate intervention are critical, making it the first action.
Choice B rationale
Preparing for anorectal surgery may be necessary if a diagnosis like Hirschsprung’s disease or imperforate anus is confirmed. However, the initial priority is to assess for signs of abdominal distention by measuring the circumference, providing crucial information for the next steps.
Choice D rationale
Monitoring strict urinary output is important for overall fluid balance and identifying complications related to fluid shifts. However, in this scenario, the priority action is to assess for abdominal distention, a potential sign of a serious underlying condition causing the symptoms observed in the infant.
