Question

TPN- Hyperalimentation:

1. TPN is a/an __________________ solution (hypotonic, hypertonic, isotonic).
2. TPN may be given via _______________________ (NG tube, PICC line, tunneled catheter).
3. TPN is prepared ________________ (hourly, daily, weekly)→ based on lab values.
4. The TPN dressing change is done with ____________________ asepsis (surgical or medical).
5. This lab value is checked every 4-6 hours when TPN is initiated: __________________ (WBC, total lipids, blood glucose)
6. A new TPN bag is hung every ______________ hours. (8, 12, 24).

Answer 1

TPN is a hypertonic solution administered via a PICC line or tunneled catheter, prepared daily based on lab values, with surgical asepsis for dressing changes, monitoring blood glucose every 4-6 hours, and replacing the TPN bag every 24 hours.

Step-by-step explanation:

TPN, or Total Parenteral Nutrition, is a type of therapy provided to patients who cannot or should not receive their nutrition through eating. The following answers provide clarity on common questions about TPN administration.

1. TPN is a/an hypertonic solution.
2. TPN may be given via a PICC line or a tunneled catheter.
3. TPN is prepared daily, based on lab values to ensure it meets the patient's current nutritional needs.
4. The TPN dressing change is done with surgical asepsis to maintain a sterile environment and prevent infection.
5. This lab value is checked every 4-6 hours when TPN is initiated: blood glucose.
6. A new TPN bag is hung every 24 hours.

Understanding the osmotic pressure and ensuring that intravenous solutions are isotonic with body fluids are crucial for patient safety, as the wrong type of solution can cause cellular damage or fluid imbalances.
