Are you using a brain sheet to keep track of your to-do items, assessments not yet charted, etc.? If no, then check with your coworkers to see what they are using and use one of theirs or make your own. The Ultimate Nursing Brain Sheet Database (33 nurse report sheet templates)
has a lot of types, and if you check the forums here, many have shared their brain sheets.
As you gain experience, you'll get better and better at time management, at least with handing four to five patients (six can be rough if it is day or evening shift). Learn to group tasks such as patient education during the medication pass as well as what IV antibiotics to run in what order when you only have one IV site.
Also, ask your coworkers what works for them, and see if what they do will work for you.
