Which of the following is correct about the administration of the pneumococcal vaccine?
The CDC recommends routine administration of pneumococcal vaccination for all adults age 18 and older.
The CDC recommends routine administration of pneumococcal conjugate vaccine (PCV13) for all children older than 2 years.
The CDC recommends routine administration of pneumococcal vaccination for all children younger than 2 years and all adults older than 65 years.
The CDC recommends routine administration of pneumococcal vaccination for all adults age 75 and older.
The Correct Answer is C
Choice A reason: This is incorrect because routine pneumococcal vaccination is not recommended for all adults starting at age 18. Adults with certain chronic conditions may be vaccinated earlier, but universal vaccination begins at older ages.
Choice B reason: This is inaccurate; the pneumococcal conjugate vaccine (PCV13) is recommended primarily for children younger than 5 years, not those older than 2 years universally, although catch-up dosing may occur.
Choice C reason: This is correct. Standard guidelines recommend routine pneumococcal vaccination for all children younger than 2 years and all adults 65 years and older, as these age groups are at higher risk for invasive pneumococcal disease.
Choice D reason: This is incorrect. Age 75 alone does not trigger routine vaccination; the recommendation is generally for all adults 65 and older, with earlier vaccination for those at higher risk.

Correct Answer is B
Explanation
Choice A reason: Pneumonia presents with infection-related symptoms and radiographic changes, not reversible airway obstruction or hyperreactivity.
Choice B reason: Correct. Asthma is characterized by reversible airway obstruction, bronchial hyperreactivity, inflammation, and structural changes like smooth muscle hypertrophy, which matches this clinical picture.
Choice C reason: Bronchitis involves inflammation of the bronchi, often due to infection, and does not typically produce reversible airway obstruction or chronic airway changes.
Choice D reason: Sinusitis affects the sinuses, not the lower airways, and would not account for wheezing or bronchial hyperreactivity.
Correct Answer is C
Explanation
Choice A reason: Avoiding sick contacts is important for infection prevention, but low platelet count primarily increases bleeding risk, not infection risk.
Choice B reason: Aspirin inhibits platelet function and is contraindicated in severe thrombocytopenia, making this statement unsafe.
Choice C reason: This is correct. Patients with very low platelet counts are at high risk of bleeding; avoiding activities that could cause trauma reduces the risk of serious hemorrhage.
Choice D reason: While rest is beneficial, stopping work and sleeping excessively does not address the primary danger of thrombocytopenia, which is bleeding risk.
