The field of nursing has evolved over time and continues to change every day. The numerous changes lead to an improvement in the quality of care provided by nurses on a daily basis. For example, nurses never wore gloves when performing most of their tasks, such as administering injections or going to the bathroom to patients. Over time, it was discovered that many patients carried diseases that were easily transferred through body fluids or blood. As a result of the discovery, nurses began wearing gloves during most of their nursing care. This helped protect not only nurses from contracting numerous diseases, but also patients. The nurses did not transfer germs and bacteria from one patient to another because they wore gloves with each patient and discarded each one when finished. This is just one example of how the quality of nursing care has changed over time. There are many others, with most of the changes involving drug delivery. Improving the accuracy and efficiency of drug distribution contributes significantly to improving the overall quality of nursing care. Medications are critical to improving the patient's health and comfort level. It is the nurse's priority to make sure the patient is safe when taking most of the medications that many of them take. Nurses must perform vital checks, reassess, and evaluate the effectiveness of all medications administered. Medications function to maintain a person's blood pressure, pulse, fluid balance, thyroid function, and many other things. There are also many different types of pain medications that are important when trying to improve a patient's health because their health is more likely to improve if they are free from pain and feel comfortable. ...... half of the sheet ......), 243-248.
