-administration of a blood transfusion
-emergent pancreas removal
-iv antibiotics
-stem cell transplantation

ANSWER: Administration of a blood transfusion

EXPLANATION:

Aplastic crisis is a potentially deadly complication of sickle cell disease that develops when erythrocyte production temporarily drops. Infection with parvovirus B-19 frequently causes aplastic crises (Saarinen et al., 1986).

Aplastic crisis may be associated with extensive bone marrow necrosis as well as acute selective erythroblastopenia

Immediate management is usually supportive involving mainly BLOOD TRANSFUSION to build up hematocrit level.

In the long term, bone marrow transplant to stimulate new cell growth is usually suggested.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.
