A nurse's initial action should be to ask to see a copy of the advance directive.
Nurses have a moral obligation to ensure that healthcare advocates base their decisions on the patient's wishes. When a patient is helpless and irreplaceable, caregivers should support decisions that are best for the patient and ensure that all values are upheld.
If you are healthy become seriously ill or are unable to make medical decisions in the future talk to your healthcare provider about completing your living will. Otherwise, ask who would like to make decisions if the patient is no longer able to make them.

Answer:
The complement system plays important role in body defense and provides innate and adaptive immune response to the body. The complement system is made up of many proteins found in the serum.
The complement system performs many roles like cell lysis, clearance of immune complex and opsonization which helps in removing the foreign molecule from blood and put them in spleen and liver for lysis.
Most of the components of complement are synthesized in the liver and binds to antigen-antibody complex to form membrane attack complex(MAC) which results in cell lysis.
Complement plays important role in phagocytosis of disease-causing microbes by phagocytic cells. By this way complement generally, prevent microbes from causing disease.
Answer:
Concentration, Temperature, Mass of Particle, Solvent /medium, surface area and permeability properties of membrane.
Explanation:
The random movement of particles causes the phenomenon called diffusion. The concentration gradients of particles pushes molecules in a direction such that molecules move from a region of high concentration to a region of lower concentration.
Diffusion is a passive process (not requiring the input of energy).
The following variables are factors that affects diffusion;
Concentration - down concentration gradient favours diffusion.
Temperature - temperature increases diffusion , the kinetic energy associated with each particle also increases.
Mass/size of Particle - Smaller particles on the other hand will diffuse faster because they can move faster.
Solvent /medium Properties - Viscosity and density of the medium greatly affect diffusion. Highly viscous and dense medium slows down diffusion.
Diffusion can occur through a membrane. The two factors that are particular to diffusion through a membrane are surface area and permeability.
