How do preschool-aged children typically understand death? (Select All that Apply.)

A. Placing the client on their side is the correct action to prevent aspiration and help keep the airway open during a seizure. It also helps drain secretions and can reduce the risk of choking.

B. Holding the client's arms and legs is not recommended during a seizure because this can lead to injury to the client and the nurse. Seizure activity should be allowed to run its course in a safe environment.

C. Placing the client back in bed during a seizure could be dangerous, as it is better to keep the client safe on the floor to prevent falling or injury. The priority is ensuring the client’s safety during the seizure rather than moving them back into bed.

D. Inserting a tongue blade in the client's mouth is an outdated practice and can lead to injury or even cause the client to bite down on the tongue blade. There is no need to insert anything into the mouth during a seizure.

A. Aplastic crisis is caused by a decrease in the production of red blood cells in the bone marrow is correct. Aplastic crisis is often triggered by an infection (such as parvovirus B19), leading to a sudden reduction in red blood cell production, which can exacerbate anemia.

B. Sequestration crisis involves the blockage of small blood vessels by sickled red blood cells is incorrect. This describes a vaso-occlusive crisis, not sequestration crisis. Sequestration crisis involves pooling of blood in the spleen or liver, leading to organ enlargement and circulatory collapse.

C. Vaso-occlusive crisis is characterized by the pooling of large amounts of blood in the spleen and liver is incorrect. Vaso-occlusive crisis is characterized by the blockage of small blood vessels by sickled cells, leading to pain, ischemia, and tissue damage.

D. Aplastic crisis is characterized by the pooling of large amounts of blood in the spleen and liver is incorrect. Aplastic crisis is primarily related to bone marrow failure and reduced red blood cell production, not blood pooling in organs.

E. Sequestration crisis is characterized by the pooling of large amounts of blood in the spleen and liver is correct. In sequestration crisis, the spleen and liver trap large amounts of blood, which can lead to hypovolemic shock and severe anemia.

F. Vaso-occlusive crisis involves the blockage of small blood vessels by sickled red blood cells is correct. Vaso-occlusive crisis occurs when sickled red blood cells obstruct blood flow in small vessels, causing pain, tissue damage, and potential organ dysfunction.
