Nobody disagrees with the obvious and commonsensical points... and it's always worth affirming what should be obvious and commonsensical... but some of it is excessively self-effacing. Did you read the document? There are 5+ graded examples for introductory, mid-point, and concluding statements (that's 5+ for each) with timing and tone of voice to ask for an observation chart. Here's the suggested template: Opening: “I’m sorry to bother you, I know you’re busy. Do you know where the chart is for bed 21?” Midpoint: "Yeah, I really appreciate it." Closing: “You’re a champion. Thanks. I really appreciate your time. Sorry to bother you.” Have you ever been busy on the wards (as lots of nurses are)? Could you imagine if a medical student went through this rigamarole to ask for an obs chart? And "You're a champion"? For getting an obs chart? How condescending does that sound? Especially from a medical student. A pleasant 5 minute coffee break does 1000x more for you in terms of building good-will and conveying kindness. Seriously, if you and a nurse are both doing scut work, just ask them if they did anything fun last weekend. Shoot the **** for a few minutes. It's fun; it's light; it's other-centered; and it's being a normal human being. That's true respect. Then ask away for whatever whenever: "Sorry, do you know where X is? Got it. Thank you." Get on with it.
