Received 2 liters of normal saline does hematocrit increase?

The saline distributes rapidly (within about 15 minutes) from the intravascular to the interstitial compartment. And there, it is stuck.

The cells have active pumps and the membrane is impermeable to sodium; similarly, chloride is trapped.
Because normal saline is isoosmotic with the extracellular fluid, water does not have any osmotic pressure to shift between compartments, and it distributes itself according to the proportional distribution of sodium (i.e. about 25% of it stays intravascular and 75% enters the interstitial fluid).

(This may not be entirely accurate. Because the osmolality of the extracellular fluid increases, some water undegoes a shift into the extracellular compartment. The new equilibrium point is 290.2 mOsm/L. To achieve this, a whole 25ml of water has to move up into the extracellular compartment. So, the intravascular volume increases not by 250ml, but by... 256ml. What a big difference that makes. In order to remain detached from pedantic hair-splitting, I have opted to omit this from all the further calculations.)

Plasma osmolality doesn't change much, because it has received a load of essentially isoosmolar fluid.
You will notice that the osmolality of the compartments increases by 0.2 mmol/L from your maths; but the osmoreceptors dont care.

A man pushes a lawn mower with a force of 200N across 50N meters of his lawn. How much work did the man perform?

krok68 [10]

Work is equal to force times distance or W = Fn x d

In this situation, you would use the following equation:
W= 200N x 50N

W= 10,000N

The man performed 10,000N of work.

ivolga24 [154]

Emergency Operations Centers (EOCs) are the National Incident Management System (NIMS) command and coordination structures that are offsite locations where staff from multiple agencies come together.

Emergency operations center (EOC) is a control facility that functions mainly for incident response. This center serves as a central intelligence arena where response team personnel and decision makers gather and analyze extremely important information, organize response activities, make decisions that guards life and property, communicates with staff and response team personnel and ensure the consistent existence and operation of the organization.

Answer:

C: After 1 hour, the pH of the solution in the PEPCID AC beaker was 9.2 and the pH of the solution in the Alka-Seltzer beaker was 8.3

Explanation:

The degree of acidity or alkalinity/basicity of a substance is its pH. The value of pH ranges from 1 to 14 with the former being extreme acidity and the latter being extreme alkalinity while pH 7 is considered neutral.

Hence, any pH below 7 is considered acidic and above 7 is considered alkaline.

Reactions involving equal volumes of an acid and a base can end in acidic, alkaline or neutral pH depending on the strength of the acid/base involved;

Equal volumes of strong acid with strong base will result in neutral pH
Equal volumes of weak acid with strong base will result in alkaline pH
Equal volume of strong acid with weak base will result in acidic pH

If substance A and B reacts with equal volume of the same acid under the same condition and the end result of A is a solution with pH of 9.2 and that of B is a pH of 8.3, it simply means substance A is a stronger base than substance B.

Hence, the only outcome that supports the hypothesis that a tablet of PEPCID AC can neutralize more stomach acid than a tablet of Alka-Seltzer is that the pH of the solution in the PEPCID AC beaker was 9.2 and the pH of the solution in the Alka-Seltzer beaker was 8.3 after being subjected to the same condition.

If an indigestion is due to excess stomach acid, the only way to reduce the acidity is to consume a substance that will decrease the degree of acidity in the stomach. This means that the patient will need to consume something that is alkaline in order to increase the pH.

Explanation:

The Germ Theory of Disease indicates that microbes are the causal agents in human disease. In modern healthcare, Germ Theory has led to a breakthrough in the treatment of infectious diseases with antibiotics such as penicillin, and the prevention of disease outbreaks through proper sanitation and vaccination.

Further Explanation:

Biology's unifying principle states that cells are the basic units of biological organisms. Cells sharing a similar origin, group together in the body to form tissues; these typically share physical features and are arranged in regular patterns. All living things, grow, respire, reproduce etc. these processes are carried out by cells, which are thus integral to their survival.

Before the discovery of cells by Robert Hooke in 1665 with a simple microscope, many scientists had long believed that life rose spontaneously over extended periods of time. Circa 1668 Francesco Redi, challenged the idea of spontaneous generation of maggots from rotting meat by placing meat in various sealed open, partially sealed and sealed containers. Sealed containers did not show the presence of maggots, and he theorized that these were likely from eggs laid on the meat by flies. This was the development of the theory disproving abiogenesis (cells arise from other living cells); this eventually proved the unifying principle we know today.

Cell theory states that living things are comprised of cells, as their smallest units capable of functioning. Microscopy helps to prove this, as cells and their varying components can readily be seen, observed and later classified.
