CASE D
The dental hygienist observes an older adult client as he walks toward her. She notes that he uses a cane, walks slowly, and appears to be short of breath. As she reviews the health history with him, the client tells her that he takes a diuretic and a "drug for his heart," which she recognizes as an angiotensin-converting enzyme (ACE) inhibitor. His respirations are 26 per minute and shallow. Pulse rate is 90 beats per minute and regular. After consultation with the client's physician, who confirms that the client is being treated for congestive heart failure (CHF) but is healthy enough for routine dental treatment, the dental hygienist begins an initial assessment.
-An automated external defibrillator (AED) has been used on a client who is not breathing and has no pulse. From the following scenarios, choose the one that is MOST correct.

A) If a shock is indicated, "clear" the client and press the "shock" button, following recommended CPR/AED techniques
B) If a shock is indicated, press the "shock" button as quickly as possible regardless of other rescuers or bystanders
C) If no shock is indicated, press the "shock" button anyway
D) If no shock is indicated, then CPR is not necessary
