The mnemonic I created was Chief IHOP
... I love the pancakes at IHOP restaurant
C: Clean hands
H: "Hello!" (introduce yourself and the CE)
I: ID band
E: Explain assessments and whatever else you'll be doing with the patient
F: Faciliate goal-oriented interaction (a critical element, but can simply be met by asking if the patient has any care questions)
I: Input/intake: includes your IV fluid check
H: Hydration status
O: Output check (foley, urine hat placement)
P: Proceed with your next AOC
Like the others have said, consider anything that is potentially "wet and not yours" as a reason to glove. IVs can leak patient-contaminated fluid or blood, so gloves are required at these sites. IV tubing and bags should not leak; they are clean coming out of the medication room, and clean on the IV pole. Oral secretions are a potential "leak". Foley bags are ones as well, and so on.
Infants are messy... burping up, leaking diapers, and drooling. Glove and gown up whenever performing most areas of care with them, since their control of fluids is a lot less than (most) adults.
After you walk into the patient's room and introduce yourself, wash your hands if you haven't done so very recently (depends on where the designated wash areas are at the hospital). I just tell the patient that I am going to wash my hands for their protection. When you put on gloves, the biggest thing to remember is to gel (or wash) after removing them.... everytime. The hospital I tested at allowed for gelling afterwards, and that makes life so much easier because you can still chat with the patient while you scrub that stuff into your hands.
I found that the 20 minute check was the easiest part of the CPNE. Remember that you have an entire sheet dedicated to that 20 minute check... the one that lists the intake, output, hydration status, etc. Makes for a nice reminder as you're filling out the information in the room.
The most difficult part of the CPNE (for me) was time management. One of my patient fails involved the meals and failure of the assigned nurse to monitor the patient's intake before my patient care time began with her. The poor elderly lady attempted to order breakfast that morning over the phone (conceirge service of sorts), but her hearing was so bad that the food service person did not complete her "order", and did not contact the floor regarding the call. The patient's assigned nurse never checked on the patient's breakfast (I mean really, how hard is it to ask your patient if she enjoyed her breakfast... uh, wha? You didn't eat? Why?). The same thing happened for lunch. So, my patient was half-starved by the time my afternoon with her rolled around, and so I helped her order a late lunch and let her eat in peace. Lost a lot of time over that. I failed that patient care attempt by a 10 minute overage. But, I still passed the CPNE weekend after passing with my second-chance patient the next day. So, consider what you could do in unusual scenarios that could eat up your precious time with the patient, and please don't believe anyone who says you'll have plenty of time. You'll need to wisely use each minute.
Hope it helps some!
