A nurse is about to administer an intermittent enteral feeding to a client who has an NG tube in place. Besides obtaining an x-ray, which of the following methods should the nurse use to verify the placement?
Inject air and listen for bubbling.
Test the pH of the gastric aspirate.
Measure the gastric residual.
Add food coloring to the formula.
The Correct Answer is B
This is done by aspirating a small amount of stomach contents and testing the pH using pH paper or a pH indicator strip. The pH of stomach contents is typically acidic (pH less than 5), indicating proper placement in the stomach.
Injecting air and listening for bubbling is not a reliable method to verify tube placement, as it can lead to complications such as pneumothorax.
Measuring gastric residual is done to assess the amount of gastric contents remaining in the stomach, but it does not confirm tube placement.
Adding food coloring to the formula is not a standard practice and does not provide reliable confirmation of tube placement.
X-ray is the gold standard method to confirm tube placement but is not typically done before every intermittent feeding unless there are concerns about tube placement

Correct Answer is A
Explanation
An oxygen saturation level of 90% is below the normal range and indicates inadequate oxygenation. This finding could indicate respiratory compromise or impaired lung function, which may require further assessment and intervention before allowing the client to ambulate.
The respiratory rate of 20 breaths per minute, apical pulse rate of 88 beats per minute, and oral temperature of 37.6°C (99.7°F) are within the expected range and do not raise immediate concerns that require reporting to the charge nurse prior to ambulation.
However, the nurse should continue to monitor these vital signs during and after ambulation to ensure stability.
Correct Answer is A
Explanation
Cotton underwear is recommended for individuals with UTIs because it allows better air circulation and helps keep the genital area dry. This can prevent the growth of bacteria and reduce the risk of further infection.
Drink orange juice daily for 3 to 4 weeks: While hydration is important for overall health, there is no specific recommendation to drink orange juice or any specific juice for the treatment of a UTI. It is generally recommended to increase fluid intake, particularly water, to help flush out the bacteria from the urinary system.
Take the prescribed antibiotic until manifestations are gone: This instruction is correct. It is important for the client to take the full course of the prescribed antibiotic as directed by their healthcare provider, even if symptoms improve before completing the entire course. This helps ensure complete eradication of the bacteria and reduces the risk of antibiotic resistance.
Restrict fluid intake to 1 L per day: Adequate fluid intake is important for UTI management as it helps flush out bacteria from the urinary system. Restricting fluid intake to 1 liter per day is not recommended and may not provide sufficient hydration. It is generally advised to drink plenty of water and other fluids throughout the day.
