NG Tubes ATI

Question 1

What is the primary purpose of a Salem tube?

Answer 1

To irrigate, feed, and remove gastric contents

Salem tubes are commonly used for gastric decompression and feeding.
* In the context of feeding tubes, irrigating means flushing the tube with a liquid, typically water, to maintain its patency and prevent blockages. This process helps ensure that the tube remains clear and open for the delivery of nutrition or medications.

Question 2

Which part of an NG tube is used for ventilation to prevent reflux of fluid?

Answer 2

The blue tube

The blue port allows for air venting to avoid reflux.

Question 3

What is a common complication of NG tube use?

Answer 3

Fluid and electrolyte imbalance

This can occur due to improper feeding or suctioning.

Question 4

Which of the following is NOT an indication for NG tube use?

Answer 4

Hypertension

Hypertension is not a reason for NG tube insertion.

Question 5

What type of suction is more commonly used in hospitals for NG tubes?

Answer 5

Intermittent suction

This method is often preferred for patient comfort.

Question 6

Before inserting a nasal tube, what should be assessed?

Answer 6

The client’s nasal passages for obstructions

Ensuring clear passages is crucial for successful tube placement.

Question 7

How is the length of an NG tube to be inserted determined?

Answer 7

By measuring from the tip of the nose to the earlobe to the xyphoid process

This measurement helps ensure proper placement in the stomach.

Question 8

What position should a patient be in during NG tube insertion?

Answer 8

Sitting at a 45-degree angle

This position aids in easier insertion and reduces aspiration risk.

Question 9

What is the purpose of checking gastric residual volume (GRV)?

Answer 9

To ensure proper digestion and absorption of tube feedings

Checking GRV helps assess the tolerance of feedings.

Question 10

What is the most accurate method of verifying NG tube placement?

Answer 10

X-ray

An X-ray provides definitive confirmation of tube placement.

Question 11

What is a potential complication if an NG tube is inserted into the lungs instead of the stomach?

Answer 11

Aspiration pneumonia

This serious condition occurs when food or fluids enter the lungs.

Question 12

What should be done before administering medications through an NG tube?

Answer 12

Check tube placement

This is vital to prevent complications and ensure safety.

Question 13

When administering medications through an NG tube, what should be done with tablets?

Answer 13

Crush them and dissolve in water

This facilitates easier passage through the tube.

Question 14

After administering medication through an NG tube, what should be done?

Answer 14

Flush the tube with water

Flushing helps prevent occlusion and ensures medication delivery.

Question 15

What type of NG tube is characterized by a weight at the end of the tubing?

Answer 15

Dobhoff tube

Dobhoff tubes are often used for feeding due to their flexibility.

Question 16

What is the maximum suction pressure that should not be exceeded for an adult during suctioning?

Answer 16

150 mmHg

Exceeding this pressure may cause injury to the mucosa.

Question 17

What color does drainage from an NG tube typically start as after surgery?

Answer 17

Dark brown

This indicates the presence of old blood and should be monitored.

Question 18

What should be done if a patient with an NG tube becomes restless or combative?

Answer 18

Assess for causes of discomfort and address them

Understanding the underlying issue is crucial for patient care.

Question 19

How often should the feeding bag be changed when using continuous tube feeding?

Answer 19

Every 24 hours

Regular changes help prevent bacterial growth.

Question 20

What is the purpose of the blue portion of an NG tube?

Answer 20

For ventilation to prevent reflux

This feature is essential for maintaining proper function.

Question 21

What should be done if GRV is over 500 ml?

Answer 21

Reconsider continuing the feed or consult practitioner

High GRV may indicate a need to adjust feeding protocols.

Question 22

What type of feeding method delivers a specific amount of nutrients at set intervals?

Answer 22

Bolus feeding

This method allows for more controlled nutrient delivery.

Question 23

What should be done to prevent bacterial growth in tube feeding?

Answer 23

Change the feeding bag every 24 hours

Proper management is key to patient safety.

Question 24

What is the purpose of elevating the head of the bed for patients with NG tubes?

Answer 24

To prevent aspiration

This position reduces the risk of fluid entering the lungs.

Question 25

What should be checked before starting a tube feeding?

Answer 25

Patient's position and tube placement ## Footnote Ensuring correct placement is crucial for safety.

Question 26

What is the purpose of flushing an NG tube with water after medication administration?

Answer 26

To prevent tube occlusion ## Footnote Flushing ensures the tube remains clear for subsequent use.

Question 27

What type of NG tube is generally used for administration of medications and feeding?

Answer 27

Small bore, single lumen tube ## Footnote These tubes are preferred for their ease of use.

Question 28

What should be done if a patient with an NG tube experiences nasal discomfort?

Answer 28

Assess for causes and provide appropriate care ## Footnote Addressing discomfort is important for patient comfort.

Question 29

What is a sign that an NG tube may be displaced?

Answer 29

Sudden onset of coughing or respiratory distress ## Footnote These symptoms indicate potential misplacement of the tube.

Question 30

What should be documented after NG tube insertion?

Answer 30

Comprehensive details including placement verification, patient tolerance, and tube position ## Footnote Thorough documentation is essential for ongoing patient care.
