Answer to Question 1

B
Chronic cough, shortness of breath, and dyspnea on exertion are the classic symptoms of COPD. Responses A, C, and D are incorrect. Heart palpitations, peripheral edema, and cyanotic nail beds may be symptoms but are not the common primary symptoms of COPD. Joint pain is not usually noted as a symptom of COPD.

Answer to Question 2

D
Glaucoma is the asymptomatic increase in intraocular pressure that is a major cause of blindness. Responses A, B, and C all affect vision and visual acuity but are not major causes of blindness. Cataracts (response A) can be surgically removed. Presbyopia (response C) can be treated with corrective lenses or bifocals. Macular degeneration (response B) causes decreased central vision but not blindness.
