A nurse is caring for an 18-month-old infant who is 12 hours postoperative following a myringotomy. Which of the following pain rating scales should the nurse use?

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:
A 2 cm scalp laceration, while a concern, is not the nurse's priority in this scenario. The child's head injury could potentially be serious, but priority should be given to neurological assessments and signs of increased intracranial pressure.
Choice B rationale:
Nasal discharge negative for glucose is not indicative of a major issue in this context. While cerebrospinal fluid (CSF) leaking from the nose after head trauma is a concern, it is not mentioned in this scenario, and this choice does not take precedence over other neurological signs.
Choice C rationale:
This is the correct answer. Asymmetric pupils can be a sign of a serious neurological issue, such as a brain injury or increased intracranial pressure. It requires immediate attention and further evaluation to assess the child's neurological status and determine the extent of the injury.
Choice D rationale:
A negative Babinski reflex is a normal finding in this context and does not require immediate priority attention. The Babinski reflex is typically present in infants and disappears as the child grows older. Its absence is expected in older children and adults.
