A nurse is reinforcing teaching with a female adolescent who has dysmenorrhea. Which of the following instructions should the nurse include?

Choice A rationale:
Apply cold packs to the lower abdomen. This is the correct answer because applying cold packs to the lower abdomen can help alleviate dysmenorrhea (painful menstrual cramps). Cold therapy helps to constrict blood vessels, reducing blood flow to the area and thus reducing pain. It's a non-pharmacological approach to managing menstrual cramps.
Choice B rationale:
Increase daily intake of fat. Increasing fat intake is not a recommended approach for managing dysmenorrhea. Balanced nutrition is important, but increasing fat intake is unlikely to significantly impact menstrual cramps. Other strategies are more effective.
Choice C rationale:
Massage the lower back area. Massaging the lower back can help with muscle relaxation and may provide some relief, but it is not as effective as applying cold packs to the lower abdomen for dysmenorrhea. Cold packs specifically target blood flow reduction to the area of pain.
Choice D rationale:
Limit physical activity. While it's generally a good idea to avoid strenuous physical activity during periods of intense pain, limiting physical activity alone is not the most effective strategy for managing dysmenorrhea. Cold packs and other interventions are more likely to provide relief.

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.
