Hi, I'm not a male but I've met many male CNA's and male Nurses! (I am also a minority CNA which I'll get into later)
Just do your best and listen to your patients especially in terms of modesty concerns. For example, don't get offended or take it personally if a woman doesn't want you doing perineal care on her and always try to ask if the patient is comfortable with what you're doing.
You'll get rid of the anxiety by just going in and doing your best. You will get more and more comfortable each clinical. I was a box of nerves when I first started my clinicals but when I got there I realized that I knew my skills, the hospital protocol, and to excessively wash my hands and it quickly turned into a place to blossom and improve not stress uncontrollably!
I actually preferred the hospital setting compared to a long term care facility. Just do what you were taught to do, don't be afraid to ask questions, and refine your teamwork skills!
Hospitals always have eyes & ears watching so don't talk bad about the patients, nurses, or violate HIPAA. You'll stand out in the class which isn't always a bad thing so if you give exceptional care and show potential they might even contact you for a job opportunity
I was also an odd one out in my group, I am Muslim so I was so nervous people wouldn't like me because I do wear a headscarf. I'll tell you now that nothing rude was ever said to me by a patient or coworker, even if they were thinking it. People looked at me and were curious so I made sure to give impeccable care, help whenever possible, and communicate to show others I was competent and could do my job without letting personal choices and their interpretation of my beliefs hinder me from going above and beyond my best.
If you know what you want, you'll get there with no trouble at all. Even if you're outnumbered by the ladies lol
