During a medication teaching session, a newly diagnosed client with panic disorder receives prescriptions for paroxetine (Paxil) 20mg daily and alprazolam (Xanax) 0.5mg as needed for panic attacks. The client appears anxious about managing the new medications and asks, “Would it be better if I just take the alprazolam every day to make sure I don’t have any panic attacks? I’m worried about having an attack work.” Which nursing response is most appropriate?

When prescribing selective serotonin reuptake inhibitors for depression, the APRN has responsibility to monitor for adverse effects. Which of the following are among those adverse effects? Select all that apply.

The following snippet of pseudo code for the producer consumer problem using semaphores has a logical error. Identify the location of the error, explain what can go wrong, and suggest a fix to eliminate the error. (Hint: you can assume that all wait and post calls would be successful and not return an error code). semaphore m(1) // initialize counter to 1 semaphore s(0); // initialize counter to 0 Producer ============= sem_wait(&m) while (buffer full) {     sem_post(&m);     sem_wait(&s); }  // insert item into the buffer sem_post(&s); sem_post(&m);   Consumer ==============    sem_wait(&m); while (buffer empty) {      sem_post(&m);      sem_wait(&s); } // remove an item from the buffer sem_post(&s); sem_post(&m);

Which of the following are the most common current indications for the use of barbiturates? 

Write pseudocode that creates a child process, switches the child’s standard output (1) and standard error (2), and lets the child process execute a program whose name is provided as a command line argument.  As an example, assume that helloworld binary’s main function is implemented as follows: int main(int argc, char **argv) {     write(1,”HELLO”,6);     write(2,”WORLD”,6);     return 0; } Let’s assume that the binary of the code you will implement is called changingWorlds would be called as  $ ./changingWorlds helloworld and after this the child process that will execute helloworld writes “HELLO” to file that was accessible through descriptor 2 in the parent process and writes “WORLD” to the file accessible through descriptor 1 in the parent process.
