The nurse is auscultating the thyroid gland and notes a bruit. Which of the following would the nurse associate with this finding?
1. Indicates stenosis of the thyroid artery.
2. Is a normal finding.
3. Indicates increased blood flow.
4. Occurs with hypothyroidism.
3
Rationale 1: A bruit does not indicate stenosis, which is when blood flow is restricted through a blood vessel.
Rationale 2: This is not a normal finding.
Rationale 3: If the thyroid is enlarged, blood flows through the arteries at an accelerated rate, producing a soft, rushing sound and is detected with the bell of the stethoscope as a bruit.
Rationale 4: Hypothyroidism can produce a smaller than normal thyroid gland and decreased blood flow.
