A nurse is assessing a client who has bradycardia. Which of the following findings should the nurse expect?

Rationale: A. While dehydration or hypovolemia can lead to tachycardia as the body attempts to maintain cardiac output, it does not typically cause bradycardia. Bradycardia usually results from conduction abnormalities, medications, or increased vagal tone rather than low fluid volume. B. Anxiety triggers sympathetic nervous system activation, which increases heart rate and blood pressure. Therefore, it is more likely to produce tachycardia rather than a slow heart rate. C. Bradycardia reduces cardiac output, which lowers cerebral perfusion. This decrease in blood flow to the brain commonly manifests as dizziness, lightheadedness, fainting, or syncope. These symptoms are critical for assessing the clinical significance of bradycardia, especially in older adults or those with cardiovascular disease. D. Fever increases metabolic demand, leading to compensatory tachycardia, not bradycardia. A slow heart rate in a febrile client would be atypical and may suggest other underlying conditions, such as conduction disorders or drug effects.
