The best and most accurate technique to identify the appropriate vein site for iv catheter insertion into the arm is to apply a tourniquet approximately 4 to 6 inches above in the arm where the catheter is to be inserted.
Applying the tourniquet causes the vein to swell from inside due to the pressure which makes the intended insertion point much more clear and visible and helps the nurse to determine if the vein is capable of accommodating the iv catheter.
C) saturated fats have only single bonds on all the carbon atoms
hope this helps :)
Answer:
Explanation:
Interphase -Interphase is the portion of the cell cycle that is not accompanied by observable changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis
Prophase- the first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears. The first prophase of meiosis includes the reduction division.
Metaphase - Metaphase is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most condensed and coiled stage (they are at their most condensed in anaphase). These chromosomes, carrying genetic information, align in the equator of the cell before being separated into each of the two daughter cells.
Anaphase - Anaphase is the stage of mitosis after the process of metaphase, when replicated chromosomes are split and the newly-copied chromosomes (daughter chromatids) are moved to opposite poles of the cell
Telophase- he final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
The substrate and the active site both need to fit together perfectly in order for the enzyme to work properly. If their shape is changed, typically through heat or a change in pH, the enzyme will not work.
