A nurse is reinforcing teaching about sibling adaptation with a parent of a child who has cystic fibrosis. Which of the following instructions should the nurse include in the teaching?

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:
The correct answer is choice A. This action is crucial to ensure accurate capillary blood glucose testing. Allowing the skin antiseptic to dry before puncturing the child's finger helps prevent contamination of the blood sample, which can lead to inaccurate results. Wet antiseptic can dilute the blood sample and affect the glucose reading.
Choice B rationale:
This choice is incorrect because placing a cool washcloth on the child's finger is not standard practice before capillary blood glucose testing. While warmth can help increase blood flow and make the puncture process more comfortable, using a cool washcloth is not recommended, as it may constrict blood vessels and make it harder to obtain a sufficient blood sample.
Choice C rationale:
This choice is incorrect because testing the first drop of blood obtained after puncturing the child's finger is not recommended. The first drop of blood can be diluted with interstitial fluid and may not provide an accurate glucose reading. It's important to wipe away the first drop and use the subsequent drop of blood for testing.
Choice D rationale:
This choice is incorrect because puncturing the center of the pad of the child's index finger is not the recommended site for capillary blood glucose testing. The sides of the fingertip contain an adequate blood supply and are less painful for the child. Puncturing the center of the fingertip can be more painful and may not yield a sufficient blood sample.
