A primigravida at 40 weeks gestation is contracting every 2 minutes, and her cervix is 9 cm dilated and 100% effaced. The fetal heart rate is 120 beats/minute. The client is screaming and her husband is alarmed. Which intervention should the nurse implement?

Choice A reason: Ensuring oxygen and medications manages exacerbations in asthma, bronchitis, and emphysema, where airway inflammation obstructs breathing. These treat symptoms, not prevent infections. Vaccines reduce influenza and pneumococcus, major exacerbation triggers, providing specific immunity to prevent severe respiratory infections, making them a higher priority.

Choice B reason: Using tissues and handwashing reduces infection spread but is less effective than vaccines for preventing exacerbations in chronic lung diseases. Influenza and pneumococcus trigger severe bronchoconstriction or inflammation. Vaccines offer targeted protection against these pathogens, prioritizing prevention over general hygiene in high-risk clients.

Choice C reason: Avoiding crowded areas in colder months reduces viral exposure, which can exacerbate asthma or COPD via inflammation. Vaccines are more effective, providing specific immunity against influenza and pneumococcus, the most common triggers of severe exacerbations, making this less critical than vaccination for preventing respiratory complications.

Choice D reason: Annual flu and PPSV23 vaccines are critical for asthma, bronchitis, and emphysema, as these conditions increase severe infection risk. Influenza and pneumococcus trigger exacerbations via airway inflammation, risking hospitalization. Vaccines stimulate antibody production, reducing infection severity, making them the top preventive measure for chronic lung disease management.

Choice A reason: Observing chest wall shape assesses for abnormalities like barrel chest, not tactile fremitus. Fremitus involves feeling vocal vibrations, increased in pneumonia due to consolidated lung tissue. Visual inspection does not evaluate vibration transmission, making it irrelevant for assessing fremitus in suspected pneumonia.

Choice B reason: Tactile fremitus is assessed by placing the palm on the chest while the client speaks, feeling vibrations through consolidated lung tissue in pneumonia. Fluid-filled alveoli enhance sound transmission, increasing fremitus. This directly evaluates lung pathology, confirming consolidation, critical for diagnosing pneumonia’s extent and severity.

Choice C reason: Using a stethoscope assesses breathing sounds like crackles, not tactile fremitus, which requires palpation of vocal vibrations. While breath sounds aid pneumonia diagnosis, fremitus specifically evaluates consolidation via vibration, making stethoscope use incorrect for this physical assessment technique focused on lung tissue density.

Choice D reason: Compressing tissue for crackling assesses crepitus or subcutaneous emphysema, not fremitus. In pneumonia, fremitus increases due to consolidation, not tissue compression. This method is irrelevant, as fremitus relies on vocal vibration transmission through palpation, making it inappropriate for assessing pneumonia-related lung changes.
