Answer:

The correct option is : D. Ethnocentrism

Explanation:

Ethnocentrism is a term used to describe an act of judgement and evaluation of another culture or ethnic group with reference to the preconceptions of one's own ethnic group or culture especially in terms of the language, customs, food, beliefs and religion. Therefore, ethnocentrism is a belief that one's ethnic group is superior in comparison to others and thus all the other ethnic groups are rated with reference to their own superior group.

Blood is taken from veins not from arteries. Why?​
frosja888 [35]
Veins are favored over arteries because they have thinner walls, and thus they are easier to pierce. There is also lower blood pressure in veins so that bleeding can be stopped more quickly and easily than with arterial puncture.

Give an example of a 2 x 2 matrix game with exactly three nash equilibria in pure strategies. Explain.
weeeeeb [17]

Answer:

A Nash equilibrium is a profile of strategies (s1,s2) such that the strategies are best responses to each other, i.e., no player can do strictly better by deviating. This helps us to find the (pure strategy) Nash equilibria.

To start, we find the best response for player 1 for each of the strategies player 2 can play. I will demonstrate this by underlining the best responses:

ABCA1–,10,101–,−10B10–––,01,11,10C−10,110–––,11,1

Player 1 is the row player, player 2 is the column player. If 2 plays column A, then player 1's best response is to play either row A or C, which gives him 1 rather than 0 as payoff. Similarly, the best response to column B is row A, and to column C it is row B.

Now we do the same for player 2 by underlining the best responses of the column player:

ABCA1–,1–0,10–––1–,−10B10–––,01,11,10–––C−10,1–10–––,11,1

So, if player 1 plays row A then player 2 best responds either with column A or column C, giving him 1 rather than 0. We also find the best responses for row B and C.

Now a pure strategy Nash equilibrium is a cell where both payoffs are underlined, i.e., where both strategies are best responses to each other. In the example, the unique pure strategy equilibrium is (A,A). (There may also be mixed strategy equilibria.) In all other cells, at least one player has an incentive to deviate (because it gives him a higher payoff).

EDIT: How to compute mixed strategy equilibria in discrete games?

In a mixed Nash strategy equilibrium, each of the players must be indifferent between any of the pure strategies played with positive probability. If this were not the case, then there is a profitable deviation (play the pure strategy with higher payoff with higher probability).

Consider player 2. He plays column A with probability p, B with probability q, and C with probability 1−p−q. We need to find p,q such that player 1 is indifferent between his pure strategies A,B,C. He is indifferent between row A (left hand side) and row B (right hand side) if p,q are such that

p+10q−10(1−q−p)=q+10(1−p−q).

He is indifferent between B and C if

q+10(1−p−q)=p+q+1−q−p=1.

You just have to solve the first condition for q as function of p, substitute q in the second condition and you have p. Inserting p again in the first gives you q.

Now we do the same with strategies for player 1 such that player 2 is indifferent. Player 1 plays A with probability x, B with probability y and C with probability 1−x−y. The two conditions that follow are

1x+10y−10(1−x−y)=x+10(1−x−y)x+10(1−x−y)=1

Solve this again to find x,y. This is a mixed-strategy equilibrium, because neither player has a profitable deviation. Remember, we constructed the profile (x,y;p,q) such that the other player is indifferent between his pure strategies. So, no matter how the other player unilaterally deviates, his expected payoff will be identical to that in equilibrium (x,y;p,q). In general, depending on the game and solutions x,y,p,q, there may be infinitely many mixed Nash equilibria, or none. The more pure strategies there are, the more tedious it is to compute mixed strategy equilibria, since we solve for N−1 variables for each player (N being the number of pure strategies of the other player).

Moreover, to find all equilibria, if there are more than 2 actions for a player, then every possible combination of actions has to be checked. Here, a player has 3 actions, and a mixed strategy equilibrium could entail mixing over all three or just any two of them. Since such a player would not have to be indifferent regarding the strategy played with probability 0, the equations you have to set up are different. In summary, manually checking for all possible mixed strategy equilibria if at least one player has more than two actions can require a lot of effort.

a nurse is preparing a medication from a vial for subcutaneous injection for a client. which action should the nurse take?
krek1111 [17]

Inject air into the vial with the eye of the needle immersed in the fluid.

A small needle is used to inject a substance into the tissue layer separating the skin and the muscle during a subcutaneous injection to deliver medication.

The steps involved in giving a subcutaneous injection are:

  • washing hands in warm water and soap.
  • assembling the necessary tools, including alcohol pads, gauze, needles, and syringes.
  • examination and cleaning of the injection site.
  • Putting the drug in the syringe entails:
  1. the vial's cap is taken off.
  2. air being injected into the syringe.
  3. inflating the virus with air.
  4. medicine discontinuation
  5. eliminating air bubbles.
  • distributing the medicine.

A threatened abortion is the potential problem.

<h3>What is threatened abortion?</h3>

The term "abortion" refers to the termination of a pregnancy before to 20 weeks of gestation. A threatening, inevitable, incomplete, full, septic, or missed abortion is one of the various forms of spontaneous abortion.

A threatened abortion is described by vaginal bleeding before 20 weeks of gestation in the presence of a positive urine and/or blood pregnancy test with a closed cervical os, without passage of sperm or eggs, and without signs of fetal or embryonic death.

The World Health Organization (WHO) defines a threatened abortion as open bleeding or pregnancy-related bloody vaginal discharge that occurs during the first half of the pregnancy without cervical dilatation.
