The client comes to the emergency department with sudden onset of dizziness. the client's hemoglobin and hematocrit suddenly dropped due to an aplastic crisis. which treatment should the nurse prepare to administer for this crisis?
-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.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.
