A patient with right lower-lobe pneumonia has been treated with IV antibiotics for 3 days. Which assessment data obtained by the nurse indicates that the treatment is effective?
The patient's white blood cell (WBC) count is 6000/μL.
Bronchial breath sounds are heard at the right base.
Increased tactile fremitus is palpable over the right chest.
The patient coughs up small amounts of green mucus.
The Correct Answer is A
A. A decrease in the white blood cell count toward normal levels indicates that the infection is responding to antibiotic treatment. A WBC count of 6000/μL is within the normal range for adults (usually 4,000–11,000/μL), which suggests that the body is no longer fighting a significant infection.
B. Bronchial breath sounds heard at the right base indicate consolidation, a sign of ongoing pneumonia or unresolved infection. This would suggest that the infection is not yet controlled, rather than an improvement.
C. Increased tactile fremitus indicates consolidation, which is commonly seen in pneumonia. It suggests that the infection is still present and has not resolved with treatment.
D. Green mucus can indicate the presence of purulent sputum and ongoing infection. Although the color of the mucus may change during the course of pneumonia, the presence of green mucus does not confirm that the infection is resolving, especially after three days of antibiotics.

Correct Answer is B
Explanation
A. Fecal output from a new colostomy typically begins within 2 to 4 days, not within 24 hours. This is due to the time needed for bowel function to resume after surgery.
B. A small amount of bleeding around the stoma can occur as part of normal healing, especially in the first few days after surgery. It should not be excessive or prolonged.
C. Raw vegetables and high-fiber foods should be avoided immediately after surgery as they can irritate the digestive tract and cause blockages in the stoma. A low-fiber diet is recommended initially.
D. The stoma should initially be red or pink in color, not purplish. A purplish color could indicate impaired circulation, which would require medical attention.

Explanation
A. A family history of esophageal cancer is a known risk factor. Genetic factors can increase the likelihood of developing esophageal cancer, especially if close family members have had the condition.
B. A diet high in glucose is not specifically associated with an increased risk of esophageal cancer. However, poor dietary habits in general, such as a high intake of processed foods or low fiber, can contribute to other health issues.
C. Irregular exercise is not a major risk factor for esophageal cancer. However, a lack of physical activity can contribute to overall health problems, including obesity, which is a known risk factor for some cancers.
D. Smoking tobacco is a significant risk factor for esophageal cancer. Smoking can damage the esophagus and increase the risk of developing both squamous cell carcinoma and adenocarcinoma of the esophagus.
