administration of TPN
TPN is typically administered through a central venous catheter to ensure that the solution is delivered directly into the bloodstream. Specialized filters are used to remove any particulate matter or air bubbles from the TPN solution before administration. a good location to insert is right subclavian vein a peripherally inserted central catheter (PICC line) is a type of central line.
TPN (total parenteral nutrition)
Total Parenteral Nutrition (TPN) is a method of providing nutrition to patients who cannot consume food orally. TPN is a solution containing a balance of nutrients, including carbohydrates, proteins, fats, vitamins, and minerals, that is administered directly into the bloodstream through a central vein.
a nurse is assessing a client and discovers the infusion pump with the client's TPN solution is not infusing. the nurse should monitor the client for which of the following conditions? a. Excessive thirst and urination b. Shakiness and diaphoresis c. Fever and chills d. Hypertension and crackles
a. excessive thirst and urination rationale: this is because if the TPN solution is not infusing, the client is at risk for developing hyperglycemia due to the sudden lack of glucose intake. Hyperglycemia can lead to excessive thirst and urination as the body attempts to excrete the excess glucose through the urine.
a nurse is assessing a client who is receiving TPN. which of the following findings should the nurse recognize as a complication of this therapy? a. Hyperglycemia b. Aspiration c. Diarrhea d. Stomatitis
a. hyperglycemia
a nurse is planning care for a client who is to start receiving total parenteral nutrition (TPN). which of the following interventions should the nurse include in the plan of care? a. use a 1.2 micron filter when infusing TPN with fat emulsions added. b. allow 18 hr for the lipids to infuse when not mixed with the TPN solution. c. change the TPN solution after 36 hr. d. change the TPN tubing every 48 hr.
a. use a 1.2 micron filter when infusing TPN with fat emulsions added.
complications
accidental lung puncture air embolus occlusion (blockage) catheter sepsis
a nurse is assessing a client who is receiving TPN therapy via an infusion pump. Which of the following actions should the nurse take? a. Obtain the client's blood glucose every 12 hr b.Change the IV tubing every 24 hr c.Change the IV site dressing every 4 days d. Weigh the client every other day.
b. change the iv tubing every 24 hrs
A nurse is caring for a client who has cancer and is receiving TPN. Which of the following lab values indicates the treatment is effective? a. Hct 43% b. WBC 8,000/uL c. Albumin 4.2 g/dL d. Calcium 9.4 mg/dL
c. albumin 4.2 g/dL
A nurse prepares to replace the nearly empty container of TPN for a client when she finds that there has been a delay in receiving the new container of solution from the pharmacy. which of the following solutions should the nurse infuse until the next container of TPN solution becomes available? a. Lactated Ringer's b. 3% sodium chloride c. Dextrose 10% in water d. 0.9% sodium chloride
c. dextrose 10% in water
indications for TPN
include severe malnutrition, inability to absorb nutrients through the gastrointestinal tract (e.g., due to bowel obstruction, short bowel syndrome, or severe inflammatory bowel disease), conditions requiring bowel rest, dysphagia (and risk for aspiration)
swelling above the PICC line
measure the circumference of both arms
