While selecting a venipuncture site for an adult client, in case if the student places the tourniquet on the upper arm for more than one minute then the nurse would have to intervene.
A tourniquet refers to a compressing or constricting apparatus used to monitor the flow of venous and arterial blood to a part of an extremity for a duration of time. The tourniquet should not be utilized for more than one minute, as this permits for blood stasis, which can result in clotting and may also lead to prolonged discomfort for the client.

The answer should be NEURONES (nerve cells).
Neurons transmit electrical signals called NERVE IMPULSES from the cell body through the axon to the end plate. The junction between the end plate and the adjacent cell is called SYNAPSE. impulses passes through the synapse by diffusion of chemicals.
Answer:
There is no regulatory protein that oxidizes these Calvin cycle enzymes; oxidation is spontaneous.
Explanation:
Four enzymes of the Calvin cycle are regulated by sunlight. These enzymes are namely Ribulose 5-phosphate kinase, fructose 1,6-bisphosphatase, sedoheptulose 1,7-bisphosphatase, and glyceraldehyde 3-phosphate dehydrogenase.
The inactive form of these enzymes has disulfide bonds between two Cys residues. In the presence of sunlight, the reduced thioredoxin that obtains electrons from PS-I via ferredoxin reduces the disulfide bonds between the Cys residues of these enzymes.
The reduction of the bonds brings about the confirmation changes to make the enzyme active.
At nightfall, these bonds are spontaneously re-oxidized and there is no reduced thioredoxin available to reduce them again. The spontaneous oxidation of the disulfide bonds of these enzymes at nightfall makes them inactive again.
