The public health nurse is working at a health fair and encourages a community member to be screened for hypertension. This is an example of which level of prevention?

Choice A reason: Markets aid nutrition, not equity directly; access does. This errors per public health standards. It’s universally distinct, indirect benefit.

Choice B reason: Prevention is care type, not equity itself. Access ensures fairness. This misaligns with nursing definitions. It’s universally distinct, not equity.

Choice C reason: Free insurance helps, but access defines equity broadly. This errors per health standards. It’s universally distinct, a means not end.

Choice D reason: Access to services ensures fair health opportunities, equity’s core. This fits public health standards. It’s universally recognized, distinctly accurate.

Choice A reason: A tetanus booster every 10 years stimulates immunity before infection occurs, a hallmark of primary prevention. It targets Clostridium tetani, preventing toxin production that causes muscle spasms, leveraging the immune system’s memory cells to neutralize the bacteria preemptively, reducing disease incidence effectively.

Choice B reason: Tetanus immunoglobulin provides immediate antibodies post-exposure, a passive immunity approach, not primary prevention. It neutralizes existing toxins from Clostridium tetani after a nail puncture, acting as a secondary measure to halt disease progression rather than preventing infection onset proactively.

Choice C reason: Screening for tetanus infection involves testing for Clostridium tetani presence or symptoms, a secondary prevention tactic. It identifies disease early for treatment, not prevention, focusing on detecting toxin-producing bacteria after exposure rather than building immunity to stop infection initially.

Choice D reason: Administering antibiotics and seizure precautions treats active tetanus, a tertiary prevention strategy. It addresses Clostridium tetani infection and toxin effects like lockjaw after onset, aiming to reduce complications and severity, not to prevent the disease from occurring initially.
