A 51-year-old male client with pneumonia has undergone several days of antibiotic and respiratory treatment. Given the following assessment findings, mark whether they indicate that the treatment was effective or ineffective:
PaCO2 55 mm Hg on a blood gas
Rhonchi in the right lung
Oxygen saturation greater than 94%
Client ambulates without shortness of breath
Correct Answer : C,D
Choice A rationale:
PaCO2 55 mm Hg on a blood gas indicates ineffective treatment. Normal PaCO2 levels range from 35-45 mm Hg.
Elevated PaCO2 (hypercapnia) suggests that the lungs are not effectively removing carbon dioxide from the body. This can be due to various factors, including:
Incomplete resolution of pneumonia Airway obstruction
Impaired respiratory muscle function
Choice B rationale:
Rhonchi in the right lung indicates ineffective treatment.
Rhonchi are coarse, rattling sounds heard in the lungs during auscultation.
They are often associated with mucus accumulation in the airways, which can occur in pneumonia.
The presence of rhonchi suggests that inflammation and mucus production persist, despite antibiotic and respiratory therapy.
Choice C rationale:
Oxygen saturation greater than 94% indicates effective treatment. Normal oxygen saturation levels are typically 95% or higher.
A saturation of 94% or above suggests that the lungs are able to effectively oxygenate the blood. This is a positive sign that the pneumonia is responding to treatment.
Choice D rationale:
Client ambulates without shortness of breath indicates effective treatment. Shortness of breath (dyspnea) is a common symptom of pneumonia.
It occurs when the lungs are unable to provide enough oxygen to the body, leading to a feeling of breathlessness.
The ability to ambulate without shortness of breath suggests that the pneumonia has improved and that the lungs are functioning more effectively.

Correct Answer is A
Explanation
Choice A rationale:
Liquefying secretions is the most crucial action to address the client's immediate respiratory concerns. Thickened mucus obstructs airflow, leading to shortness of breath, productive cough, and difficulty breathing upon exertion. Increasing fluid intake thins mucus, making it easier to expel and improving ventilation. This directly addresses the client's current symptoms and promotes airway clearance.
Hydration and Mucociliary Clearance: Adequate hydration is indispensable for optimal mucociliary clearance, the natural mechanism that removes mucus from the airways. Fluids moisten the respiratory tract, allowing cilia (tiny hair-like structures) to effectively move mucus upwards, where it can be coughed out or swallowed.
Thinning Mucus: Water acts as a natural expectorant, thinning mucus and reducing its viscosity. This makes it easier for the client to cough up the mucus, clearing the airways and reducing the sensation of breathlessness.
Decreasing Mucus Production: Dehydration can trigger the body to produce more mucus as a protective response. By staying hydrated, the client can help prevent excessive mucus production, further easing symptoms.
Supporting Overall Respiratory Health: Proper hydration maintains the health of the respiratory system's tissues and cells, promoting efficient gas exchange and reducing inflammation.
Preventing Dehydration-Related Complications: Dehydration can exacerbate respiratory problems and lead to other complications, such as fatigue, headaches, and impaired immune function. Maintaining adequate fluid intake helps prevent these issues.
Key points to emphasize to the client:
Drink fluids throughout the day, even if not feeling thirsty.
Water is the best choice, but clear broths, juices, and herbal teas can also contribute to fluid intake. Avoid caffeine and alcohol, as they can be dehydrating.
Monitor urine output to ensure adequate hydration (urine should be pale yellow or clear).
Increase fluid intake during periods of increased mucus production, such as during respiratory infections or exercise.
Correct Answer is A
Explanation
Choice A rationale:
Direct identification of the causative organism: A culture for sensitive organisms is the most direct and definitive way to identify the specific bacteria or other microorganisms that are causing the infection in the wound. This information is crucial for guiding the selection of the most appropriate antibiotic therapy.
Tailored antibiotic therapy: By knowing the exact organism responsible, healthcare providers can prescribe antibiotics that are specifically effective against that organism, ensuring optimal treatment and reducing the risk of antibiotic resistance.
Informed infection control measures: The results of the culture can also inform appropriate infection control measures to prevent the spread of the infection to other patients or healthcare workers.
Monitoring treatment effectiveness: Cultures can also be used to monitor the effectiveness of antibiotic therapy. If the culture results show that the bacteria are no longer present after a course of antibiotics, this indicates that the treatment has been successful.
Choice B rationale:
Non-specific marker of inflammation: C-reactive protein (CRP) is a non-specific marker of inflammation that can be elevated in various conditions, including infections, but also in non-infectious conditions such as autoimmune diseases and trauma.
Limited diagnostic value for wound infections: While an elevated CRP level may suggest the presence of an infection, it does not provide information about the specific causative organism, which is essential for guiding antibiotic therapy.
Supplementary role: CRP levels can be used in conjunction with other clinical findings and laboratory tests to assess the severity of an infection and monitor the response to treatment, but it should not be relied upon as a sole diagnostic tool for wound infections.
Choice C rationale:
Not directly indicative of wound infection: Blood pH level primarily reflects the acid-base balance of the body and is not directly indicative of a wound infection.
Alterations in other conditions: Blood pH can be altered in various conditions, including respiratory and metabolic disorders, and is not specific to wound infections.
Limited role in diagnosis: While significant alterations in blood pH may suggest a serious systemic infection, it does not provide information about the location or causative organism of the infection.
Choice D rationale:
Not directly related to wound infection: Serum blood glucose level is primarily used to monitor diabetes and is not directly related to wound infections.
Impaired wound healing in diabetes: While elevated blood glucose levels can impair wound healing and increase the risk of infections in diabetic patients, it is not a diagnostic test for wound infections in general.
Secondary consideration: Blood glucose levels may be considered as part of the overall assessment of a patient with a wound infection, particularly in those with diabetes, but it is not a primary diagnostic tool.
