Is the following code a good solution to the critical section problem? Make sure you talk about all three requirements. The solution is meant for just two processes, numbered 0 and 1 for convenience and passed to the function using the variable i. /* flag is a shared variable; one for each process */extern bool flag[2] = { false, false };process ( const uint i ) /* i = 0 or i = 1 */{   while ( 1 )   {      while ( flag[1-i] );      flag[i] = true;       critical_section();       flag[i] = false;      remainder_section();   }}

Suppose you had the 3 separate processes, running the code below:process0 ( const unsigned int i) /* i = 0 or i = 1 or i = 2 */{   // Do stuff    // Task 0    // Later stuff}process1 ( const unsigned int i) /* i = 0 or i = 1 or i = 2 */{   // Do stuff    // Task 1    // Later stuff}process2 ( const unsigned int i) /* i = 0 or i = 1 or i = 2 */{   // Do stuff    // Task 2    // Later stuff} Describe or show how you would ensure that task 0 was done before task 1 and that task 1was done before task 2 using message queues. Make sure to specify when all messages wouldbe sent or received by inserting pseudocode in the above code or describing where you would insert code.

Briefly compare and contrast a mode switch and a process switch. Give an example of something that would cause each of them.

You are starting Fred, a white male, on anti-hypertensive medication today. Fred has a history of  diabetes, controlled with Glucophage (metformin). Based on this information, you opt to initiate which medication to treat his HTN?

*After a diagnosis of hypertension has been determined for a child, a sign that coarctation of the aorta is the cause should be considered if:

*Shawn, a 7 year old AA male, is being brought in by his mother with the following symptoms: 1) drooling, 2) increased respiratory effort, and 3) muffled speech. Shawn has not taken an antipyretic and today’s temperature is 102.8. Based on this information alone, the MOST probable diagnosis would be:

There is a penalty for each day an assignment is late.

*Kyle is a 9 year old male with a history of severe asthma exacerbations that does not use a peak flow meter at home. You recommend that he start using one now that he is old enough to understand. The most important reason you recommend this is because it:

Jean Close is a 38 year old female you are seeing in clinic today and she tells you she has been smoking marijuana for years, and she does not believe it interferes with her life. You explain that potential long-term sequelae of marijuana use includes which of the following?

A 25y/o female wth a history of menorrhagia comes in for fatigue. You suspect she has iron deficiency anemia.  Which of the follow lab results would confirm your diagnosis?
