What symptom may indicate that a patient is experiencing discomfort due to improper positioning?

A patient experiencing discomfort due to improper positioning may display symptoms such as nausea and dizziness. These signs can occur when the body is not aligned correctly, leading to pressure on nerves, reduced blood flow, or discomfort in muscles and joints. When a person is positioned improperly for an extended period, it can result in physical strain or impair circulation, which may in turn trigger feelings of nausea or dizziness.

In contrast, the other options reflect states that are generally not associated with discomfort. Increased energy and symptoms of comfort and relaxation suggest an optimal positioning that supports the patient's needs and promotes well-being. An increased heart rate might suggest stress or anxiety but, in this context, isn’t a direct symptom of discomfort due to positioning. Therefore, experiencing nausea and dizziness is a clear indication that a patient's positioning may require reassessment and adjustment.
