The public health nurse understands that making sure that essential community-oriented health services are available defines which of the core public health functions?

Choice A reason: Malaria is common globally, but dengue leads in U.S. travel cases. This errors per epidemiology data. It’s universally distinct, less frequent here.

Choice B reason: Yellow fever is rare in U.S. travel; dengue prevails. This misaligns with public health standards. It’s universally distinct, not top vector.

Choice C reason: Dengue is the most common travel-introduced vector disease in U.S. This fits epidemiology standards. It’s universally recognized, distinctly accurate.

Choice D reason: Onchocerciasis is rare in U.S.; dengue dominates travel vectors. This errors per nursing knowledge. It’s universally distinct, less relevant.

Choice A reason: Increasing seizure medication dosage is tertiary prevention, managing an existing condition to prevent worsening, like seizures. It’s reactive, adjusting treatment for epilepsy control, not detecting new issues, distinguishing it from early identification efforts in disease progression clearly and fully here.

Choice B reason: Educating on nutrition is primary prevention, stopping disease onset, like obesity. It builds health before conditions develop, targeting the general population, not screening or managing existing illness, separating it from secondary’s focus on early detection distinctly and comprehensively overall.

Choice C reason: Educating on hypertension medication side effects is tertiary, supporting treatment adherence for diagnosed patients. It manages an existing condition, not screening for new issues, contrasting with secondary prevention’s aim to catch disease early before symptoms escalate biologically and practically here.

Choice D reason: A lipid panel for type 2 diabetes is secondary prevention, screening for complications like hyperlipidemia early. It detects issues in an at-risk group before symptoms, enabling intervention, aligning with secondary’s focus on early identification and management epidemiologically and effectively in practice fully.
