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 D
Explanation
Choice A rationale:
Anorexia is a common symptom of cirrhosis, but it is not the most immediate concern in a client with esophageal varices.
Anorexia can result from various factors, including impaired liver function, hormonal imbalances, early satiety due to ascites,
and nausea.
While it's important to address anorexia to maintain nutritional status, it doesn't directly indicate a life-threatening
complication like bleeding varices.
Choice B rationale:
Brown, foamy urine is a characteristic of kidney problems, specifically proteinuria.
It's not directly associated with esophageal varices or their complications.
While cirrhosis can affect kidney function due to fluid imbalances and impaired filtering, brown, foamy urine wouldn't be the
primary indicator of bleeding varices.
Choice C rationale:
Clay-colored stool is a sign of biliary obstruction, which can occur in cirrhosis due to impaired bile flow.
However, it's not a direct indicator of bleeding varices.
Clay-colored stool results from a lack of bile pigments in the stool, which give it its typical brown color.
Choice D rationale:
Hematemesis, or vomiting of blood, is the most critical symptom to monitor in a client with esophageal varices.
Here's why:
Esophageal varices are enlarged, swollen veins in the esophagus that develop due to increased pressure in the portal venous
system, a common consequence of cirrhosis.
These varices are fragile and prone to rupture, which can lead to massive, life-threatening bleeding.
Hematemesis is a clear sign that variceal bleeding has occurred and requires immediate intervention.
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.
