- Palpating for blood pressure
The vast majority of health-care facilities throughout the United States take patients’ blood-pressure measurements automatically, but this wasn’t always the case. Nurses used to rely on palpation to obtain blood-pressure measurements. To obtain a patient’s blood pressure in this manner, nurses would inflate and deflate a compression cuff while feeling for the disappearance and reemergence of the radial pulse.
- Shaving patients prior to surgery
Up until fairly recently, hairy patients had their incision sites shaved prior to surgery. New evidence suggests that this leads to an increased risk of infection, and many hospitals have eliminated this practice. Now, instead of using a razor, nurses use clippers to cut away excessive hair as a part of their preoperative preparations.
- Shaking mercury thermometers
Now that digital thermometers are used to obtain patients’ temperatures, the sight of a nurse shaking a mercury thermometer is extremely rare. In the past, however, nurses could be seen shaking mercury thermometers in hospitals on a daily basis. The reason that these old-school thermometers were shaken is that the mercury would often cling to the inner sides of the thermometer. Prior to taking a new temperature reading, bringing the majority of the mercury back down into the bulb by shaking the thermometer was the best way to ensure accuracy.
- Cutting urinary catheters during removal
While cutting urinary catheters during removal is not recommended, some nurses and doctors still utilize this practice. It’s considered unsafe for two reasons primarily. Firstly, traction on the catheter could cause it to retract into the bladder if it’s cut. Secondly, the balloon might not deflate, which turns a simple catheter removal into something much more difficult and costly.
- Irrigating NG tubes with Coca-Cola
Many old-school nurses swear by Coca-Cola for NG tube flushing. In theory, this is due to the coke’s acidity. Regardless of the reason behind this method’s supposed effectiveness, it’s not recommended as it can affect the plastic tubing. Before using coke, juice, or something similar to flush an NG tube, refer to your facility’s guidelines. More likely than not, using water when flushing an NG tube will be the preferred method.
- Treating congestive heart failure (CHF) with rotating tourniquets
CHF patients used to be treated with rotating tourniquets. Essentially, these tourniquets were applied to the lower limbs to diminish venous return. These days, however, we have a wide variety of effective diuretics that can be used to help decrease the strain that excess fluid volume puts on the heart. Not only is this treatment more comfortable for patients than applying tourniquets, it’s much more effective.
