A fellow nurse thinks the doctor will prescribe Penicillin. Do you agree? Why or why not? B) A third nurse thinks Polymyxin B might be a good choice. Polymyxin B has the same mechanism of action and complications that Gramicidin has. Is this nurse correct that Polymyxin B is a good choice for your patient? Why or why not? C) The doctor ultimately prescribes tetracycline to be given immediately, but orders a test of the culture against multiple antibiotics. What is the target for tetracycline? What is the name of the test the doctor is ordering?

A process running on a Linux system has become unresponsive and is consuming excessive CPU. A user investigates the program and decides to terminate it. The user uses the following commands and affects the process’ PCB in the following ways:   The user first runs top, which lists every process and its [q1] read from the pcb, along with its pid and [q2] — which is used by the scheduler to order ready processes. Next, the user runs ps using the pid and inspects the [q3] to read process details, recorded in the process’s PCB. Finally, the user runs kill on the process, which causes a state transition from RUNNING to [q4].

Krishin wants to introduce a new SWAP instruction to the LC-2200 ISA that follows the specification below: Syntax: SWAP Rx, Ry Semantics: Places the contents of Rx into Ry and the contents of Ry into Rx   Krishin realizes that this instruction needs to write to 2 registers in the WB stage, which is a problem because the dual-ported register file of the classic 5-stage LC-2200 pipeline does not support accomplishing this in one clock cycle. He decides to modify the register file to support 2 simultaneous writes to the register file in the same clock cycle. Which of the following hazards does this modification address?
