Answer: the nurse will refer this child to a specialist for a bone marrow biopsy.
Explanation:
From the symptoms which where observed by the primary health care provider, the child had recurrent fevers, bone pain, and a recent loss of weight. While the physical examination revealed scattered petechiae, lymphadenopathy, and bruising. On further Laboratory diagnosis of the blood film, the full blood count revealed:
--> thrombocytopenia ( low platelet level)
--> anemia( lack of red blood cells) and
--> an elevated white blood cell count.
The major importance of full blood count is to evaluate the general health and detect a variety of of disorders. Since the blood picture is not normal, the health care provider should refer the child for BONE MARROW BIOPSY.
This is because the blood cells are produced from the bone marrow. Bone marrow biopsy is a test done to show if the bone marrow is healthy and able to make normal amount of blood cells.
The results of the bone marrow biopsy will help the primary care nurse to determine the cause of the abnormalities seen in the blood picture and will give the best directions to follow for an appropriate diagnosis and treatment.
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.
B ) it’s increase in cytosol allows muscle shortening due to the formation of bridges between actin and myosin
Answer:
The answer is A true
Explanation:
The accumulation of atheroma plaque on the wall of the aorta leads to a stiffness of the aorta, which makes the intraluminal pressure greater, which is reflected in a greater force that the ventricle has to make to eject the blood to the aorta.
