A nurse is assisting with the care of a school-age child who has shigella. Which of the following actions should the nurse take?

Choice A rationale:
Decrease daily oral fluid intake. Rationale: This choice is not appropriate for a client experiencing a vaso-occlusive crisis in sickle cell anemia. In this crisis, there is a risk of dehydration due to increased fluid loss, and decreasing oral fluid intake would exacerbate this issue. Adequate hydration is important to prevent further sickling of red blood cells and maintain organ perfusion.
Choice B rationale:
Maintain bed rest to prevent hypoxemia. Rationale: This is the correct choice. During a vaso-occlusive crisis in sickle cell anemia, blood flow to certain tissues is restricted, leading to tissue hypoxia and pain. Bed rest is recommended to reduce metabolic demands and oxygen consumption, helping to prevent further tissue damage and improve oxygenation. It also reduces the risk of complications such as thrombosis and respiratory compromise.
Choice C rationale:
Apply cold compresses to painful joints. Rationale: Applying cold compresses is not a recommended intervention for vaso-occlusive crisis in sickle cell anemia. Cold can exacerbate vasoconstriction and further compromise blood flow to the affected tissues. Warm compresses or warm baths might be more appropriate to promote vasodilation and alleviate pain.
Choice D rationale:
Administer meperidine to eliminate a fever. Rationale: Administering meperidine solely to eliminate a fever is not the primary focus of care for a vaso-occlusive crisis. The priority is to manage pain and improve tissue perfusion. Meperidine is an opioid analgesic that can be used to manage severe pain associated with sickle cell crises, but it should be given with caution due to the risk of respiratory depression and the potential for addiction.

Choice A rationale:
Implementing fluid restrictions is not recommended for a child with diabetic ketoacidosis (DKA). DKA is characterized by dehydration and electrolyte imbalances, and fluid replacement is a crucial aspect of its management. Restricting fluids could worsen dehydration and hinder the correction of metabolic imbalances.
Choice B rationale:
(Correct Choice) Monitoring vital signs every 8 hours is an important intervention for a school-age child with DKA. Vital signs, including heart rate, respiratory rate, blood pressure, and temperature, provide valuable information about the child's overall condition, fluid status, and response to treatment. More frequent monitoring might be necessary during the acute phase of DKA.
Choice C rationale:
Initiating continuous cardiac monitoring is not typically indicated for a school-age child with DKA. While DKA can have effects on the cardiovascular system, continuous cardiac monitoring is reserved for more critical situations where immediate changes in heart rhythm need to be detected.
Choice D rationale:
Administering subcutaneous insulin 30 minutes before meals is not appropriate for a child with DKA. In DKA management, insulin is typically administered intravenously to achieve more precise control over blood glucose levels. Subcutaneous insulin might not provide the rapid and consistent action needed to address the acute hyperglycemia and metabolic acidosis in DKA.
