nausea,

vomiting,

bloating,

diarrhea,

constipation

54

Infectious

A

Aspiration

57
Q

Complications of Enteral Nutrition

Management:

A

Observe residuals.

Watch for signs and symptoms of gastric intolerance.

Do not add medications to enteral formulas.

58
Q

Complications of Enteral Nutrition

Management:

Why do you need to aspirate the contents? What amount is normal to aspirate someone?

A

It is important to aspirate the contents to see if they are tolerating the feeding.

When aspirating someone, upto 250mL is normal. But it also depends on the facility.

61
Q

Parenteral Nutrition Formulas

What does TPN require?

A

TPN requires a central line (save one port)

62
Q

Parenteral Nutrition Formulas

A

Verify orders for each ingredient

Refrigerated solution

63
Q

Parenteral Nutrition Formulas

A

Do not inject any med into this line

64
Q

Pneumothorax during insertion

Air embolism during insertion

Clotted catheter line

Catheter displacement

Catheter contamination

Sepsis

Hyperglycemia: supplement with insulin

79
Q

Complications of Catheter & Parenteral Nutrition

Since hyperglycemia can occur, what must be done?

A

Hyperglycemia: supplement with insulin

80
Q

Complications of Catheter & Parenteral Nutrition

What is pneumothorax?

A

Pneumothorax- air in the chest cavity which could lead to a collapsed lung.
