1) Nurses deal with difficult physical and emotional demands in their jobs, from long hours and stressful situations like resuscitations to disrespect and abuse from patients and families. 2) They advocate for patients, perform medical tasks like checking stitches and emptying bedpans, and deal with understaffing that prevents them from spending more time with each patient. 3) Despite these challenges, nurses find fulfillment in making a difference for patients and enabling recoveries, though they remain overworked and underappreciated with little rest.
