We're on a med surg floor (not urology) but colo rectal and our nurses do look at "the area"
and ALL parts of the patients body when doing the assessment. Usually a pcna (nurse assistant is present to help look at parts as well to be their "witness") This is because we've found in the past really "odd" things under or on the patient.
You won't believe how many patients will put things under them. ie pens, pencils, bottles, books, tape, cell phones, etc. I had one pt place a switch blade under him. You can imagine my surprise when the pt turned and it popped open at me!
For whatever reasons this is also the time we learn that the pt has a fungal issue, rash, STD, etc and we get the doctor to treat them. Or we learn that the pt has a history of having swollen testicles and refuses to tell the doctor in advance of surgery!
We've learned our lessons and now it's just the thing we all do without question...
However I'm in agreement that many male pts just can't wait to show off their body parts at all hours of the day/night.
Which can be frustrating when you're trying to educate the pt or ambulate them.
