While assessing placement of a nasogastric tube (NGT), the nurse aspirates cloudy green fluid into a syringe. Which intervention should the nurse implement?
Send fluid specimen to the lab.
Withdraw the NGT and reinsert.
Connect the NGT to wall suction.
Determine pH value of specimen.
The Correct Answer is D
Choice A
This is unnecessary and not a standard clinical practice for confirming NGT placement.
Choice B
Withdrawing the NGT and reinsert should not be implemented. If the NGT is in the wrong place, reinserting it without further assessment could worsen the situation. The nurse should not reinsert the NGT until the correct placement is confirmed.
Choice C
Connecting the NGT to wall suction should not be implemented. Connecting the NGT to wall suction without verifying its placement could cause harm, especially if the tube is in the respiratory tract.
Choice D
This is the most evidence-based bedside method to confirm placement after the initial X-ray. Gastric aspirate typically has a pH of 5.0 or less. If the pH is higher (e.g., >6.0), it may indicate that the tube is in the lungs or the small intestine.

Correct Answer is B
Explanation
Choice A
Client with a nasogastric tube to low, intermittent suction is not correct. While there is a risk of aspiration with a nasogastric tube in place, the tube is intended to help drain stomach contents, reducing the risk of aspiration. However, if the tube is not properly positioned or managed, there could still be some risk.
Choice B
Client who has sensory aphasia and is receiving a clear liquid diet is correct. Sensory aphasia refers to a language disorder that affects a person's ability to understand language and communication. This client may have difficulty swallowing safely and effectively, which increases the risk of aspiration. Additionally, a clear liquid diet consists of thin liquids that are more likely to be aspirated compared to thicker fluids.
Choice C
Client receiving 30% oxygen via a non-rebreather face mask is not correct. Oxygen therapy can increase the risk of drying the airways and potentially increasing the risk of aspiration, but if the oxygen mask is properly fitted and humidified, the risk may be minimized.
Choice D
Client experiencing dysphagia who is prescribed a full liquid diet is not correct. Dysphagia refers to difficulty swallowing, which can increase the risk of aspiration. However, a full liquid diet includes thicker liquids that are less likely to be aspirated compared to thin liquids. Still, the risk of aspiration exists, especially if the client has severe dysphagia.
