2. The American Heart Association currently recommends antibiotic prophylaxis for a
ff ff ff ff ff ff ff ff ff
patientwith which of the following cardiac conditions?
ff f ff ff ff ff ff ff
a. Mitral valve prolapse ff ff
b. Prosthetic heart valve ff ff
c. Rheumatic heart disease ff ff
d. Pacemakers for cardiac arrhythmias ff ff ff
ANS: B ff
Previously, the American Heart Association (AHA) recommended antibiotic prophylaxis
ff ff ff ff ff ff ff ff
formany patients with heart murmurs caused by valvular disease (e.g., mitral valve
ff f ff ff ff ff ff ff ff ff ff ff ff
prolapse, rheumatic heart disease) in an effort to prevent infective endocarditis; however,
ff ff ff ff ff ff ff ff ff ff ff ff
current guidelines omit this recommendation on the basis of accumulated scientific
ff ff ff ff ff ff ff ff ff ff ff
evidence. If a murmur is due to certain specific cardiac conditions (e.g., previous
ff ff ff ff ff ff ff ff ff ff ff ff ff
endocarditis, prosthetic heart valve, complex congenital cyanotic heart disease), the AHA
ff ff ff ff ff ff ff ff ff ff ff
continues to recommend antibiotic prophylaxis for most dental procedures.

ANS: B ff
Symptoms and signs consistent with allergy include itching, urticaria (hives), rash,
ff ff ff ff ff ff ff ff ff ff
swelling,wheezing, angioedema, runny nose, and tearing eyes. Isolated signs and
ff f ff ff ff ff ff ff ff ff ff
symptoms such as nausea, vomiting, heart palpitations, and fainting generally are not of
ff ff ff ff ff ff ff ff ff ff ff ff ff
an allergic origin but rather are manifestations of drug intolerance, adverse side effects, or
ff ff ff ff ff ff ff ff ff ff ff ff ff ff
psychogenic reactions.

incidenceof tuberculosis.
ff f ff
d. A diagnosis of active TB is made by a purified protein derivative (PPD) skin test.
ff ff ff ff ff ff ff ff ff ff ff ff ff ff
ANS: C ff
The potential coexistence of tuberculosis and acquired immunodeficiency syndrome
ff ff ff ff ff ff ff ff
(AIDS) should be explored because patients with AIDS have a high incidence of
ff ff ff ff ff ff ff ff ff ff ff ff ff
tuberculosis. A positive result on skin testing means specifically that the person has at
ff ff ff ff ff ff ff ff ff ff ff ff ff ff
some time been infected with TB, not necessarily that active disease is present. Most
ff ff ff ff ff ff ff ff ff ff ff ff ff ff
patients who become positive skin testers do not develop active disease. A diagnosis of
ff ff ff ff ff ff ff ff ff ff ff ff ff ff
active TB is made by chestx-ray, imaging, sputum culture, and clinical examination.
