Final answer:
The priority nursing diagnosis for a patient with ESRD is typically fluid volume excess due to impaired kidney function. A patient with a low blood pressure, confusion, and thirst may be in hypovolemic shock, requiring immediate medical attention.
Step-by-step explanation:
The priority nursing diagnosis for a patient diagnosed with End Stage Renal Disease (ESRD) reflects the most critical and life-threatening issues the patient might face. When looking at the provided options, B. Fluid volume excess is often the highest priority because ESRD results in the kidneys' inability to manage fluid and electrolyte balance. This can lead to severe complications such as pulmonary edema, hypertension, and heart failure. Therefore, Fluid volume excess is typically the priority diagnosis for initial stabilization and treatment. A patient arriving in the emergency department with a blood pressure of 70/45, confusion, and complains of thirst is likely to be experiencing hypovolemic shock, possibly due to severe dehydration or bleeding. The low blood pressure indicates a lack of adequate blood flow to organs, and confusion is a sign that the brain is not receiving enough oxygen. Thirst is a body's way of indicating fluid deficiency. Prompt assessment and treatment are crucial to prevent organ failure and other severe complications.
