A cardiac catheterization of a client with heart disease indicates the following blockages: 95% proximal left anterior descending (LAD), 99% proximal circumflex, and ? % proximal right coronary artery (RCA). The client later asks the nurse 'what does all this mean for me?' What information should the nurse provide?
- A. Blood supply to the heart is diminished by atherosclerotic lesions, which necessitate lifestyle changes.
- B. Blood vessels supplying the pumping chamber have blockages indicating a past heart attack.
- C. Three main arteries have major blockages, with only 1 to 5% of blood flow getting through to the heart muscle.
- D. The heart is not receiving enough blood, so there is a risk of heart failure and fluid retention.
Correct Answer: C
Rationale: This explanation provides a clear understanding of the severity of the blockages and the implications for the client's heart function.

Characteristic indices in anaemia of chronic inflammation:
- A. Increased MCV
- B. Decreased ferritin

Which is an important nursing consideration when suctioning a young child who has had heart surgery?
- A. Perform suctioning at least every hour.
- B. Suction for no longer than 30 seconds at a time.
- C. Administer supplemental oxygen before and after suctioning.
- D. Expect symptoms of respiratory distress when suctioning.
Correct Answer: C
Rationale: If suctioning is indicated, supplemental oxygen is administered with a manual resuscitation bag before and after the procedure to prevent hypoxia. Suctioning should be done only as indicated, not on a routine basis. The child should be suctioned for no more than 5 seconds at one time. Symptoms of respiratory distress are avoided by using appropriate technique.
