A nurse is assessing the care area of a client who is prescribed a protective environment.
The client's room has a high-efficiency particulate air filtration system.

For which of the following findings should the nurse intervene?

Choice A rationale

Chlamydia trachomatis infection can cause inflammation of the urethra (urethritis) and cervix (cervicitis). This inflammation can lead to dysuria, or painful urination, which is a common symptom in both male and female clients. The symptom typically subsides as the infection is resolved with appropriate antibiotic treatment.

Choice B rationale

Chlamydia is a bacterial infection, not a viral one. Therefore, it is treated with an antibiotic, not an antiviral medication. The typical duration of treatment is much shorter, usually a single dose or a 7-day course, not 30 days, which is an unnecessarily long treatment course for this infection.

Choice C rationale

Chlamydia is a highly transmissible sexually transmitted infection. It is a critical public health responsibility for the infected individual to notify their sexual partners from the past 2 months. This allows for prompt testing and treatment of partners, which is essential to prevent re-infection of the client and further community spread.

Choice D rationale

To prevent further transmission and re-infection, clients should be advised to abstain from sexual activity until both the client and their sexual partners have completed the full course of treatment and symptoms have resolved. This practice is crucial to interrupting the chain of infection and ensuring the effectiveness of the treatment.

Choice E rationale

Completing treatment for chlamydia does not confer acquired immunity. A client can be reinfected with chlamydia if they engage in unprotected sexual contact with an infected partner in the future. Therefore, ongoing safe sexual practices are necessary to prevent recurrence.

Choice A rationale: Regulation of industrial pollution represents a primary prevention measure because it prevents harmful exposures before disease occurs. Airborne particulates, heavy metals like lead, and contaminated water from industrial discharge contribute to chronic respiratory disease, neurological impairment, and carcinogenesis. By addressing environmental hazards at their source, the nurse prevents the initial onset of illness across the population rather than intervening after disease develops, thus meeting the scientific definition of primary prevention at the community level.

Choice B rationale: Screening for health concerns such as elevated blood pressure, lead levels, or signs of abuse is classified as secondary prevention. This is because screening identifies disease at an early stage but does not prevent its occurrence. Normal blood pressure ranges are 90–120 mmHg systolic and 60–80 mmHg diastolic; detecting hypertension outside these limits is secondary rather than primary. Therefore, while scientifically beneficial, screening is not a primary prevention intervention.

Choice C rationale: Providing treatment for chronic conditions such as diabetes or hypertension falls under tertiary prevention. This strategy reduces complications, optimizes function, and delays progression of established illness but does not prevent disease onset. For example, diabetes management with insulin or hypertension management with antihypertensives reduces morbidity, yet the pathology already exists. As a result, this approach scientifically cannot be classified as primary prevention but instead as a tertiary, restorative intervention.

Choice D rationale: Implementing a school-based program on healthy relationships constitutes a primary prevention intervention because it aims to prevent intimate partner violence and unhealthy social patterns before they develop. Educational strategies modify risk factors by promoting protective behaviors in youth populations. Primary prevention focuses on avoiding the occurrence of violence, not detecting or treating it after occurrence. Therefore, this intervention is correctly categorized as primary prevention at the population level.

Choice E rationale: Providing information to leaders about creating a community garden represents a primary prevention activity because it addresses modifiable upstream determinants of chronic disease. Access to fruits and vegetables lowers the risk of hypertension, obesity, and type 2 diabetes. Normal fasting glucose should remain between 70–100 mg/dL, and diets high in processed foods elevate this risk. Community gardens improve nutrition access before illness develops, aligning with primary prevention science.

Choice F rationale: Assisting survivors in finding counseling represents tertiary prevention. At this stage, violence has already occurred, and counseling addresses the consequences to restore mental and emotional health. Tertiary prevention focuses on reducing long-term impacts rather than preventing the initial occurrence. Thus, while scientifically important for recovery and resilience, counseling does not fulfill the definition of primary prevention and is therefore not applicable as the correct answer here.

Choice G rationale: Requesting yearly water testing results is a secondary prevention measure. Surveillance identifies contaminants such as lead levels above the normal reference of less than 5 µg/dL in children but does not prevent the contamination from occurring. Monitoring allows early detection of exposure but still requires corrective action after the hazard is present. Therefore, this scientifically aligns with secondary prevention rather than primary prevention.
