If exhibited by a pregnant woman, what represents a positive sign of pregnancy?

Choice A rationale:
Correction of acidosis is not the primary intervention for vaso-occlusive sickle cell crisis. The crisis primarily involves pain due to the obstruction of blood flow by sickled cells. Correcting acidosis is not a direct treatment for this condition.
Choice B rationale:
Adequate hydration is essential in managing vaso-occlusive sickle cell crisis. Proper hydration helps prevent dehydration, which can worsen the crisis and lead to complications. Hydration helps maintain blood flow and prevent further sickling of red blood cells.
Choice C rationale:
Pain management is a crucial intervention for a child with vaso-occlusive sickle cell crisis. Pain results from tissue ischemia caused by sickled red blood cells. Effective pain management, often with analgesics, helps improve the child's comfort and quality of life during the crisis.
Choice D rationale:
Administration of heparin is not indicated for vaso-occlusive sickle cell crisis. Heparin is an anticoagulant that prevents blood clot formation. In sickle cell crisis, the primary issue is the obstruction of blood flow by sickled cells, not the formation of clots. Administering heparin may not address the underlying problem and can lead to potential complications.
Choice E rationale:
Replacement of factor VIII is not relevant to vaso-occlusive sickle cell crisis. Factor VIII is a protein involved in blood clotting and is primarily used in the treatment of hemophilia, a different condition unrelated to sickle cell crisis.

Choice A rationale:
Kimberly and Amanda sharing clay to each make things represents cooperative play, not parallel play. Cooperative play involves interaction and collaboration between children, whereas parallel play involves children playing side by side without interacting.
Choice B rationale:
Brian playing with his truck next to Kristina playing with her truck demonstrates parallel play. In parallel play, children play independently but alongside others, showing interest in what others are doing but without direct interaction.
Choice C rationale:
Adam playing a board game with Kyle, Steven, and Erich represents cooperative play, not parallel play. Cooperative play involves shared activities and collaboration, while parallel play involves independent activities in proximity to others.
Choice D rationale:
Danielle playing with a music box on her mother's lap is an example of solitary play, where a child plays alone without regard to others. Solitary play is common in younger children and is different from parallel play.
