Upon assessment, the nurse notices that the patient’s respirations have increased, and the tip of the nose and earlobes are becoming cyanotic (blue). The nurse finds that the patient’s pulse rate is over 100 beats per minute. According to Maslow’s hierarchy of needs, which patient need should the nurse address first?

@X@user.full_name@X@ @GMU: The reaction below is a exothermic reaction. What would one have to do to increase the size of the equilibrium constant?CaO(s) + CO2(g)→CaCO3(s)
