A chest radiograph film is ordered for a child with suspected cardiac problems. The child’s parent asks the nurse, “What will the radiograph show about the heart?†What knowledge about the x-ray should the nurse include in the response to the parents?
- A. Bones of chest but not the heart
- B. Measurement of electrical potential generated from heart muscle
- C. Permanent record of heart size and configuration
- D. Computerized image of heart vessels and tissues
Correct Answer: C
Rationale: A chest radiograph will provide information on the heart size and pulmonary blood-flow patterns. It will provide a baseline for future comparisons. The heart will be visible, as well as the sternum and ribs. Electrocardiography (ECG) measures the electrical potential generated from heart muscle. Echocardiography will produce a computerized image of the heart vessels and tissues by using sound waves.

- D. There are copper deposits on the cornea
Correct Answer: D
Rationale: Copper deposits on the cornea (Kayser-Fleischer rings) are a hallmark of Wilson's disease, a genetic disorder leading to copper accumulation in tissues.
