Answer:
For a 65-year-old patient with emphysema and pneumonia, the nurse should recommend the patient receive the pneumococcal vaccine.
Step-by-step explanation:
The pneumococcal vaccine helps protect against Streptococcus pneumoniae, a bacterium that can cause pneumonia and other serious infections. Since the patient has pneumonia, it is important to recommend this vaccine to prevent future infections.
The other vaccines listed are not specifically indicated for emphysema and pneumonia.
S. aureus is a bacterium that can cause infections, but it is not typically prevented with a vaccine.
H. influenzae is a bacterium that can cause respiratory infections, but the vaccine for H. influenzae is usually given to young children and individuals with specific risk factors.
Bacille Calmette-Guérin (BCG) is a vaccine primarily used to prevent tuberculosis, and it is not indicated for emphysema and pneumonia.
In summary, the nurse should recommend the pneumococcal vaccine for a 65-year-old patient with emphysema and pneumonia to help prevent future infections.
