Answer to Question 1

ANS: C
Because pneumococcal and H. influenzae pneumonia occur with higher frequency in patients with HIV than they do in the average population, an HIV test is recommended for patients with community-acquired pneumonia who are between the ages of 15 and 54 years. HIV testing is also recommended for other individuals who engage in behaviors that put them at risk for HIV.

Answer to Question 2

ANS: A
Factors that contribute to a poor Gram stain specimen include: lack of productive cough, prior antibiotic therapy, and contamination by oral secretions as specimens contaminated with oropha-ryngeal epithelial cells are unsatisfactory for analysis.
