After a nasogastric tube (NGT) is inserted for tube feedings, the test to confirm placement is ate to be used to treat this imbalance?
Select one:
Regular intermittent bubbling when the end of the tube is submerged in water
No coughing or choking when the tube was inserted
X-Ray confirmation
Hearing a rush of air in the stomach when 1mL of air is injected into the tube
The Correct Answer is C
A. Bubbling when submerged in water is not a reliable method and may indicate tracheal placement, which is unsafe.
B. Lack of coughing or choking does not confirm safe placement, as patients can silently aspirate or tolerate malpositioned tubes.
C. The gold standard for confirming NGT placement is X-ray imaging, especially before initiating feedings, to ensure the tube is properly placed in the stomach and not the lungs.
D. Hearing air over the stomach is an older technique that is not considered safe or accurate for initial confirmation, as sounds can be misleading.

C. The total volume to infuse is 100 mL over 30 minutes (0.5 hours).

Correct Answer is B
Explanation
A. While nausea and vomiting are common side effects of many chemotherapy agents, this is not specific to vesicants, which are drugs that can cause tissue damage if they leak outside the vein.
B. Vesicant chemotherapy agents can cause severe tissue damage, necrosis, and ulceration if they extravasate (leak into surrounding tissue). Close monitoring of the IV site for signs of redness, swelling, or pain is essential.
C. This may indicate gastrointestinal or bladder irritation from other types of chemotherapy agents, but it is not the hallmark concern with vesicants.
D. This is unrelated to vesicant properties. Orthostatic hypotension may occur from dehydration or autonomic effects, but not from vesicant infiltration.
