What is the recommended temperature for irrigation fluid used on the delicate, brain tissue? What is the highest setting you should use on the irrigation fluid warmer to maintain the desired solution temperature? (there are two separate answers to this question. The formatting of the answers is not a range, but two answers listed on the same line)

A 10-year-old female patient arrives in the emergency department after falling from a playground slide and injuring her head. She lost consciousness at the scene but is awake on arrival to the ED. She complains of nausea and left-sided headache but responds to verbal commands appropriately.  During the examination by the neurosurgeon, she loses consciousness again, becomes hypertensive and bradycardic. Her left pupil is now fixed and dilated. The surgeon calls the OR to set up an emergency craniotomy procedure. Why did the surgeon make the right choice and choose to schedule the case as an emergency?

In neurosurgery- the standard of practice is for the surgical technologist to hand the microinstruments to the surgeons  ___,  keep the tips of instruments and bipolar tips clean and free of debris, and keep the _____ on the field at all times. 

The neurosurgeon performing a craniotomy in room 9  does not believe in hemostats because they feel the serrations affect wound healing. He asks for the “other things to stop bleeding that we throw away”. The surgical technologists should hand the surgeon a/an___.

For a principal energy level n = 5, how many sublevels (subshells) exist?

For the reaction N2 + 3 H2 → 2 NH3, if 5.0 g N2 reacts with 2.0 g H2, which is the limiting reactant?

A playground merry-go-round has radius R and rotational inertia I. It is initially at rest. A child of mass m runs with speed v tangent to the rim and jumps on. The resulting angular velocity is:

Two wheels roll without slipping with the same linear speed. Wheel B has three times the radius of Wheel A. Compared with Wheel A, the angular velocity of Wheel B is:

An ice skater with rotational inertia I₀ spins with angular speed ω₀. She pulls in her arms and her angular speed becomes 3ω₀. Her new rotational inertia is:
