The nurse is assessing a patient with hypothyroidism. Which findings should the nurse expect for this patient?
Select all that apply.
1. change in heart rate from 80 bpm to 60 bpm on auscultation
2. decreased stroke volume from 70 mL/beat to 50 mL/beat per echocardiogram
3. new finding of pericardial effusion per chest x-ray
4. left descending coronary artery narrowing per angiogram
5. increased cardiac output from 3,000 mL/min to 4,000 mL/min per echocardiogram
Correct Answer: 1, 2, 3, 4
A thyroid hormone deficit causes a reduction in heart rate and stroke volume, resulting in decreased cardiac output. There may also be an accumulation of fluid in the pericardial sac, and coronary artery disease may be present. Increased cardiac output is not associated with hypothyroidism.
