Oxygenation is important because oxygen needs to reach all the organs of the body in order for them to maintain homeostasis. When oxygen levels are low (under 90%) it indicates oxygen is not reaching all body cells. Shortness of breath indicates poor oxygenation, fluid overload, or possible pulmonary emboli. Vital signs need to be taken frequently to monitor for any changes in the body. Dehydration can cause low blood pressure. Increased pulse can indicate poor blood supply to the heart or high anxiety. Temperature is important to help rule out any signs of infection. Mental status is monitored by asking the patient if they know who they are, where they are and past health history. When this is compromised it makes it difficult to do any further assessment. Most diabetics need their blood sugar levels monitored daily. Blood sugar levels indicate if a person has a low or high blood sugar. When sugar levels in the body are low, this can cause confusion, disorientation and ultimately coma. When sugar levels are high this can cause increased thirst, hunger and irritability. Fluid intake and output measurements are important as they allow the nurse to assess how well the kidneys are functioning. Listening to the lungs for crackles or wheezes would indicate if there was fluid volume overload or congestive heart failure (CHF). CHF can cause shortness of breath. Assessing the level of pain and where it is, will help the nurse determine what part of the body is experiencing de-compensation…
