The nurse is caring for a patient who is to receive a transfusion of packed red blood cells. the patient has a 22-gauge iv in his arm with 0.9% normal saline infusing. what intervention will the nurse perform before obtaining the packed red blood cells from the blood bank?

Insert an 18- or 20-gauge angiocatheter into the patient's other arm.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
