60
NG tube - triple lumen
- Usually used for irrigation and suction simultaneously, such as a GI bleed
61
Why provide oral care for patient with NG tube?
- Patient only has to mouth breathe
| - NG tube will decrease peristalsis, oral care will stimulate this
62

64
What solution do you use for irrigation?
- what the dr orders
| - can be water or NS
65
Why would you use NS to irrigate?
prevent electrolyte imbalance
66
How much solution do you use to irrigate?
30-40 mL
67
When would you irrigate?

| - Patient is nauseous and want to vomit - tube is clogged
68
How do you put in solution when irrigating?
- Gently
- If fluid doesn't go in, draw back out, and try again
- If fluid still doesn't go in may need to replace the NG tube because it is more than likely clogged
