AH2 Respiratory Flashcards
The nurse assesses a client with a closed chest tube drainage system that is cracked. What should the nurse do?
Disconnect chest tube from the system and submerge the chest tube in a bottle of sterile saline in order to maintain the water seal. The system will then need to be replaced. A clamp should be kept at bedside in case the system needs to be changed. A nurse should NEVER clamp a chest tube without a written prescription from the HCP. The drainage system (chest tube and bottle of sterile water) should be kept below the level of the chest if this complication occurs.
what are NG tubes used for?
to intubate the stomach; removes fluids or gas to decompress stomach and promote comfort. alls surgical anastomoses to heal without distension; decrease risk of aspiration, administer meds to clients who cant swallow. to irrigate the stomach and remove toxic substances such as poison
A single lumen tube used to remove gastric contents via intermittent suction or to provide tube feedings
Levin tube
a double lumen NG tube with an air vent (pig tail) used for decompression with intermittent continuous suction
Salem Sump Tube
What is important to remember about the air vent in a Salem Sump Tube?
it should not be clamped and keep it above the level of the stomach. If leakage occurs through the air vent, instill 30 mL of air into the air vent and irrigate the main lumen with NS
When do you check residual volumes in an intubated patient?
q4h, before each feeding, and before giving meds
What amount of residual indicates you should hold the feeding?
more than 100mL due to increased risk for aspiration with levels above 100mL
What do you do before instilling anything through an NG tube?
aspirate stomach contents and test stomach pH (a pH of 3.5 or lower indicates that the tip of the tube is in a gastric location)
How often do you change the sterile dressing of surgically placed gastrostomy or jejunostomy tubes?
q8h
How often do you irrigate an NG tube?
q4h to assess and maintain patency of the tube
gently instill 30-50mL of water or NS with an irrigation syringe
What is the purpose of a cyclical feeding?
cyclical feeding is administered in the daytime or nighttime for approx 8-16 hours using an infusion pump. Feedings at night allow for more freedom during the day
What about bowel sounds and tube feeding?
hold feeding and notify HCP if no BS
If a client is comatose, how do you position them for a tube feeding?
high fowlers on right side
What position is a client in for continuous feeding?
semi-fowlers at all times
How often do you change the feeding container and tubing?
q24h
Do not hang more solution than required for what time period in order to reduce bacterial growth opportunity?
4hours
What do you do after administering a tube feeding?
flush tube with 30-50mL of water or NS using an irrigation syringe after a feeding
Cantor tube
single lumen intestinal tube
miller-abbott tube
double lumen intestinal tube
How do you remove an intestinal tube?
the tungsten weight is removed from the balloon portion of the tube with a syringe and the tube is gradually (6”qh) as prescribed by HCP
a triple lumen gastric tube with an inflatable esophageal balloon (compresses esophageal varices), an inflatable gastric balloon (applies pressure at the cardioesophageal junction), and a gastric aspiration lumen. A NG tube is also inserted in the opposite naris to collect secretions that accumulate above the esophageal balloon
Sengstaken-Blakemore tube
a four lumen gastric tube for aspirating esophagopharyngeal secretions
minnesota tube
What special consideration do you need to make with a minnesota gastric tube?
keep scissors at the bedside at all times and monitor pt for respiratory distress-if this occurs, cut the tubes to deflate the balloons
How do you prevent ulceration or necrosis of the esophaguss
release esophageal pressure at intervals as prescribed or by agency policy
