Correct Answer is D
Explanation
A. Auscultating the right upper quadrant of the abdomen while injecting air into the tube is an outdated and unreliable method for confirming tube placement. This technique can lead to false positives and is not recommended.
B. Obtaining radiography of the abdomen is a highly accurate method for confirming nasogastric tube placement but is not always the first-line method due to the need for imaging and exposure to radiation. However, it may be used if other methods are uncertain.
C. Auscultating the left upper quadrant of the abdomen while injecting air into the tube is another outdated and unreliable method, similar to auscultating the right upper quadrant.
D. Checking the pH of fluid aspirated from the tube is the most accurate and recommended method. Gastric fluid typically has a pH of 1.5 to 3.5, whereas respiratory or intestinal fluids have higher pH levels. Checking the pH is a simple and reliable way to confirm the placement of the nasogastric tube.
Correct Answer is B
Explanation
A. Discontinuing the tube feeding and transitioning to parenteral nutrition is not the first action, as the residual volume may be manageable with additional interventions.
B. A residual volume of 200 mL is above the usual threshold, so the nurse should stop the feeding, wait, and recheck the residual to assess if it improves.
C. While positioning can help gastric emptying, the immediate action should be to stop the feeding and reassess before continuing.
D. Continuing the feeding without rechecking the residual volume would be premature, as the volume is higher than expected, potentially increasing the risk of aspiration.
