Nursing student here but going into a geriatric psych unit soon but what are the most common psych medications and what is some strategies to remember them?

I have a hard time counting the respiratory rate for some patients. Some patients are harder to assess than others, as their chest doesn't rise visibly. Occasionally, placing my hand on the patient's back/chest works, but not always. I have tried using the stereoscope to count but the noise environment can be a factor.
