A nurse is preparing a presentation on coronary heart disease (CHD) for a community women's club. Which statements should the nurse include in the presentation?
 
  Select all that apply.
  1. The epigastric pain and nausea experienced with a heart attack are often attributed to heartburn.
  2. Common symptoms of myocardial infarction (MI) include shortness of breath and fatigue.
  3. Women are more likely to have an unrecognized myocardial infarction.
  4. Weakness of the legs and back often precede a heart attack.
  5. The mortality rate of young women having an MI is 50  lower than that of men.

Question 2

The patient has a pacemaker with one pacing spike seen on the ECG before every QRS complex. There is no change in the pacemaker rhythm over time, with rest or with activity. The nurse realizes the patient has what type of pacemaker?
 
  1. asynchronous pacing
  2. demand pacing
  3. dual-chamber pacing
  4. atrial single-chamber pacing

Answer to Question 1

Correct Answer: 1, 2, 3
Common symptoms of MI in women include epigastric pain or nausea, which is blamed on heartburn, shortness of breath, fatigue, and weakness of the shoulders and upper arms. Silent or unrecognized heart attack occurs more frequently in women than men. Weakness of the legs and back does not precede a heart attack. The mortality rate of young women having an MI is twice that of men.

Answer to Question 2

Correct Answer: 1
Asynchronous pacing delivers a pacing stimulus at a set rate regardless of intrinsic cardiac activity. A demand pacemaker spike varies with the heart rate. A dual-chamber pacer normally produces two pacing spikes, one before the P wave and one before the QRS. An atrial pacer would produce a spike, normally with a P wave that follows it prior to the QRS.
