Question 61

When a client questions the nurse as to the purpose of exercise electrocardiography (ECG) in the diagnosis of cardiovascular disorders, the nurses response should be based on the fact that:

  1. The test provides a baseline for further tests
  2. The procedure simulates usual daily activity and myocardial performance
  3. The client can be monitored while cardiac conditioning and heart toning are done
  4. Ischemia can be diagnosed because exercise increasesO2 consumption and demand

Question 62

In assessing cardiovascular clients with progression of aortic stenosis, the nurse should be aware that there is typically:

  1. Decreased pulmonary blood flow and cyanosis
  2. Increased pressure in the pulmonary veins and pulmonary edema
  3. Systemic venous engorgement
  4. Increased left ventricular systolic pressures and hypertrophy

Question 63

The cardiac client who exhibits the symptoms of disorientation, lethargy, and seizures may be exhibiting a toxic reaction to:
