Compounding a sterile IV medication must be done in the pharmacy
Nat2105 [25]

Answer:  The answer is C - clean room.  

Explanation:  You prepare a sterile IV medication in a clean room.  A fume hood is used in a kitchen.  You prepare a sterile IV medication in a clean room, ISO class 7 and inside that room is an ISO class 5 area - either an area that achieves this or inside a primary engineering control.  A PEC is a laminar air flow hood - either horizontal or vertical.  Or, if you do not have an ISO class 7 area, you can use a biological safety cabinet or Compounding Aseptic (CAI) and Containment Isolators (CACI) that can be certified to use a room that is less than ISO class 7.  The only reason you would ever prepare a sterile IV medication on a counter is in an emergency situation for "immediate use."  Immediate use is defined as the entire contents will be used within 60 minutes of the preparation.

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.

How do vaccines work? Do they work against viruses and bacteria? Why there<br> are so many vaccines.
Liono4ka [1.6K]

Answer:

Vaccines train our immune systems to create proteins that fight disease, known as ‘antibodies’, just as would happen when we are exposed to a disease but – crucially – vaccines work without making us sick. Live, attenuated vaccines fight viruses and bacteria. These vaccines

contain a version of the living virus or bacteria that has been weakened

so that it does not cause serious disease in people with healthy immune

systems. Because live, attenuated vaccines are the closest thing to a

natural infection, they are good teachers for the immune system.

Examples of live, attenuated vaccines include measles, mumps, and

rubella vaccine (MMR) and varicella (chickenpox) vaccine. Even

though they are very effective, not everyone can receive these vaccines.

Children with weakened immune systems—for example, those who are

undergoing chemotherapy—cannot get live vaccines. Those are only some vaccines, of course not all vaccines inject a live virus into your body. And of course, there are so many vaccines because (unfortunately) there are so many diseases!

Todd weighs 170 lb (77 kg) and consumes approximately 190 gm of protein each day. His current protein intake may result in _____
Lera25 [3.4K]

Answer:

The correct answer is option D. loss of calcium.

Explanation:

The appropriate protein intake in an average person is 0.8 gm per kg of body weight. By calculating it is clear that he is taking a very high amount of protein that can lead to many negative impacts and one of them is the loss of calcium.

Studies have suggested that protein intake in high amounts can lead to an increase in urinary excretion of calcium.  

Thus, the correct answer is option D. loss calcium.
