To check for proper cuff size, the American Heart Association recommends comparing the cuff with your patient's arm. Most nurses use the diaphragm of the stethoscope, but you should use the bell to auscultate indirect arterial blood pressures. Don't put too much pressure on the bell; you may occlude arterial flow and dampen out the low frequencies.
As you know, using too small a cuff to measure an obese person's blood pressure can cause a falsely elevated reading. Failing to support the patient's arm, which causes isometric muscle contraction, can also lead to false measurements. In short, the more rested and relaxed your patient is while you're taking a reading, the more reliable your measurement will be. This flow produces Korotkoff's sounds: sharp topping or knocking sounds at each contraction. Determine whether your patient has smoked or drunk alcoholic beverages within the last 15 minutes.

As I was walking out of a restaurant I had an aha moment when I saw this empty dining table with the hanging light and colorful frames. They were happy when I showed them the photo and I was happy 'cause I could give them a smiling moment. As part of a pre-legal seminar my group and I were taken to a criminal court to witness trials, among other things. Despite not having my SLR, this monsoon, which occurred at sunset, spoke for itself on my camera phone.

Loved the way he enjoyed a smoke sitting in front of his car, facing the river in the forest. Shooting in black-and-white in any light can help develop your photographer’s eye by letting you concentrate on the relationship between light and shadow without the distraction of color.
In low light, camera phones slow the shutter speed to let in more light and have a longer opportunity to capture movement. When composing a picture, imagine two horizontal lines and two vertical lines crossing like a tic-tac-toe grid on top of it. Get used to your camera phone’s timing so when something interesting happens, you’ll have a good feel for the point when you need to press the shutter release to capture the most interesting moment. Hold the camera phone with both hands and brace your upper arms against your body when you shoot. Place strong lines and divisions like the horizon on the gridlines and let elements of interest fall on the intersections.
