Aclient is using an over-the-counter nasal spray containing pseudoephedrine to treat allergic rhinitis. which instruction about this medication would be most appropriate for the nurse to provide for the client?

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.

explanation:

answer: 21

step-by-step explanation:

divide 630 by 30. 30 goes into 630 21 times
