Answer:
Taking into account that:
The flow velocity u of a fluid is a vector field
u = u (x, t)
What gives the velocity of a Fluid Plot at position x y time t.
q = || u ||
Now if the flow is continuous as it happens in the blood vessels then:
The flow of a fluid is said to be constant if it does not move over time, that is why the variant would be 0.
Explanation:
As for the pump with narrow vessels, there the area would be less, therefore the flow also and the flow velocity as well. Adding that the friction with the walls increases as it is narrower, thus generating an increase in pressure with the flow of the liquid.
So this is where we have to put emphasis on the biophysics branch that explains the following:
The Venturi effect is explained by the Bernoulli Principle and the principle of continuity of mass. If the flow rate of a fluid is constant but the section decreases, the speed necessarily increases after crossing this section. By the theorem of conservation of mechanical energy, if the kinetic energy increases, the energy determined by the value of pressure necessarily decreases.
Indeed, according to Bernoulli's principle:
P 1 + 21 ρv 12 + ρgh 1 = P 2 + 21 ρv 22 + ρgh 2

The answer is <u>bleeding.</u>
<u />
Risk the nurse is trying to prevent is bleeding.
What is bleeding?
Blood loss from the circulatory system is referred to as bleeding. Small cuts and abrasions to severe cuts and amputations are examples of possible causes. Body injuries can also cause internal bleeding, which can range in severity from modest (visible as superficial bruising) to significant hemorrhage.
In order to stop serious external or internal bleeding while waiting for emergency medical assistance, first aid is essential. Applying direct pressure to the wound, maintaining the pressure using pads and bandages, and, if feasible, lifting the damaged limb above the level of the heart are all first aid measures to manage external bleeding.

Answer: False
Explanation:
In case any victim is suspected from the spinal or neck injury then the victim should not be moved on any side. He must be left untouched.
Doing so can make the person permanently paralysed. Try to cover the front and back of the neck with rolled piece of clothe but do not move the person unnecessarily.
Hence, the given statement is False.
