What is crucial to monitor with a patient on TPN?
A patient on TPN must have blood work monitored closely to prevent the complications of refeeding syndrome. Blood work may be ordered as often as every six hours upon initiation of TPN.
What labs do you monitor with TPN?
Weight, complete blood count, electrolytes, and blood urea nitrogen should be monitored often (eg, daily for inpatients). Plasma glucose should be monitored every 6 hours until patients and glucose levels become stable. Fluid intake and output should be monitored continuously.
What are some of the possible complications of a patient receiving TPN?
Possible complications associated with TPN include:
- Dehydration and electrolyte Imbalances.
- Thrombosis (blood clots)
- Hyperglycemia (high blood sugars)
- Hypoglycemia (low blood sugars)
- Infection.
- Liver Failure.
- Micronutrient deficiencies (vitamin and minerals)
Which laboratory test is the best indicator of a client in need of TPN?
Explanation: Serum albumin levels can help measure protein levels in the body and are good indicators for nutrition status. The other choices would not reflect malnutrition status. You just studied 6 terms!
What is TPN test?
Laboratory testing is an objective means of assessing organ function, electrolyte levels and to ensure the patient is receiving the appropriate calorie, carbohydrate and lipid combinations to meet nutritional needs without causing liver or other organ damage.
What is TPN monitoring?
What electrolyte imbalance can TPN cause?
The most common electrolyte abnormalities during TPN were hypophosphatemia (24 cases, 30%), and hypomagnesaemia (22 cases; 27.5%) with no differences by gender. Hypokalaemia also occurred in 22 patients (27.5%) and was more common in women by 29.6% (p < 0.05).
What is TPN blood test?
What are the indications for TPN?
Indications for total parenteral nutrition
- Inadequate absorption resulting from short bowel syndrome.
- Gastrointestinal fistula.
- Bowel obstruction.
- Prolonged bowel rest.
- Severe malnutrition, significant weight loss and/or hypoproteinaemia when enteral therapy is not possible.
What lab is the best indicator of nutritional status?
Serum proteins (albumin, transferrin, prealbumin, retinol-binding protein) are perhaps the most widely used laboratory measures of nutritional status. They are hepatically produced negative acute-phase reactants with reduced levels during systemic inflammation.
What lab values do you need prior to starting TPN?
It is especially important to measure phosphorus and potassium levels because intracellular shifts occur with feeding. It is also important to know the levels of glucose, sodium, and magnesium.
How are laboratory tests used to monitor TPN?
TPN Monitoring Schedule. Laboratory testing is an objective means of assessing organ function, electrolyte levels and to ensure the patient is receiving the appropriate calorie, carbohydrate and lipid combinations to meet nutritional needs without causing liver or other organ damage.
When is TPN not available in short notice?
The specific type of nutrition (TPN or jejunal feed etc) is not often available in short notice. Doctor in charge must be responsible for nutrition of their patient with the help of the dietician, they must ensure that nutrition is commenced at weekends when dietician is not available.
How often should blood tests be done with TPN?
Abnormalities can be recognized and changes made to the TPN formula to correct any abnormalities before they become life threatening. When a patient is initially placed on TPN, lab and vital signs are usually performed much more frequently. Once the patient is stable blood tests can be performed less often.
What are the disadvantages of total parenteral nutrition ( TPN )?
Because TPN solutions are concentrated and can cause thrombosis of peripheral veins, a central venous catheter is usually required. Parenteral nutrition should not be used routinely in patients with an intact GI tract. Compared with enteral nutrition, it has the following disadvantages: It causes more complications.
