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.
An 8-month-old infant has a hypercyanotic spell while blood is being drawn. What is the priority nursing action?
- A. Assess for neurologic defects
- B. Place the child in the knee-chest position
- C. Begin cardiopulmonary resuscitation
- D. Prepare family for imminent death
Correct Answer: B
Rationale: The first action is to place the infant in the knee-chest position. Blow-by oxygen may be indicated. Neurologic defects are unlikely. The child should be assessed for airway, breathing, and circulation. Often, calming the child and administering oxygen and morphine can alleviate the hypercyanotic spell.
