What is a common symptom of anemia that a nurse should assess in clients?

Fatigue and weakness are hallmark symptoms of anemia, as the condition often results from a deficiency in red blood cells or hemoglobin, which are critical for transporting oxygen throughout the body. When the body's tissues do not receive enough oxygen, individuals commonly experience decreased energy levels and an increased sense of fatigue. This lack of oxygen can also lead to weakness, making everyday activities feel more strenuous.

While other symptoms can be associated with anemia, such as changes in vision or headaches, they are not as universally present or defining as fatigue and weakness. Elevated blood pressure typically does not correlate with anemia and can actually vary depending on the underlying cause or other health conditions of the individual. Thus, assessing for fatigue and weakness is a critical part of evaluating a client for anemia.
