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 D
Explanation
A. Sleeping on the stomach is not recommended for patients with GERD because it can increase pressure on the stomach, promoting acid reflux.
B. Lying on the right side can actually worsen GERD symptoms because it allows acid to flow more easily into the esophagus from the stomach, due to the positioning of the stomach and esophagus.
C. Sleeping on the back with the head flat does not provide sufficient elevation to prevent acid reflux, which can lead to symptoms worsening during the night.
D. Sleeping on the left side helps reduce the likelihood of acid reflux. This position prevents the stomach's contents from moving up into the esophagus, making it the most effective sleeping position for GERD.
Correct Answer is ["A","C","D","E"]
Explanation
A. Serum phosphorus is crucial to monitor in patients at risk for refeeding syndrome. Hypophosphatemia is a key sign of the syndrome and can lead to severe complications, such as respiratory failure and cardiac arrhythmias.
B. Serum blood glucose levels are important to monitor, especially since refeeding syndrome can cause rapid shifts in glucose metabolism. However, it is not a primary test to diagnose refeeding syndrome. Blood glucose monitoring will be part of the overall management, but not the core test for the syndrome.
C. Serum calcium should be monitored because it can also decrease in refeeding syndrome due to shifts in phosphate and magnesium levels, which may affect calcium metabolism.
D. Serum potassium is essential to monitor because hypokalemia often occurs in refeeding syndrome as the body shifts electrolytes into cells. This can cause muscle weakness, arrhythmias, and other serious complications.
E. Serum magnesium is also important to check, as hypomagnesemia is commonly seen in refeeding syndrome and can contribute to neurological and cardiac symptoms.
