The nurse is changing the central line dressing of a client receiving parenteral nutrition (PN) and notes that the catheter insertion site appears reddened. The nurse should next assess which item? 1. Client's temperature 2. Expiration date on the bag 3. Time of last dressing change 4. Tightness of tubing connections

1. Client's temperature Redness at the catheter insertion site is a possible indication of infection. The nurse would next assess for other signs of infection. Of the options given, the temperature is the next item to assess. The tightness of tubing connections should be assessed each time the PN is checked; loose connections would result in leakage, not skin redness. The expiration date on the bag is a viable option, but this also should be checked at the time the solution is hung and with each shift change. The time of the last dressing change should be checked with each shift change.

A client with parenteral nutrition (PN) infusing has disconnected the tubing from the central line catheter. The nurse assesses the client and suspects an air embolism. The nurse should immediately place the client in which position? 1. On the left side, with the head lower than the feet 2. On the left side, with the head higher than the feet 3. On the right side, with the head lower than the feet 4. On the right side, with the head higher than the feet

1. On the left side, with the head lower than the feet Air embolism occurs when air enters the catheter system, such as when the system is opened for intravenous (IV) tubing changes or when the IV tubing disconnects. Air embolism is a critical situation; if it is suspected, the client should be placed in a left side-lying position. The head should be lower than the feet. This position is used to minimize the effect of the air traveling as a bolus to the lungs by trapping it in the right side of the heart. The positions in the remaining options are inappropriate if an air embolism is suspected.

The nurse is caring for a group of adult clients on an acute care medical-surgical nursing unit. The nurse understands that which client would be the least likely candidate for parenteral nutrition (PN)? 1. A 66-year-old client with extensive burns 2. A 42-year-old client who has had an open cholecystectomy 3. A 27-year-old client with severe exacerbation of Crohn's disease 4. A 35-year-old client with persistent nausea and vomiting from chemotherapy

2. A 42-year-old client who has had an open cholecystectomy Parenteral nutrition is *indicated in clients whose gastrointestinal tracts are not functional or must be rested, cannot take in a diet enterally for extended periods, or have increased metabolic need*. Examples of these conditions include those clients with burns, exacerbation of Crohn's disease, and persistent nausea and vomiting due to chemotherapy. Other clients would be those who have had extensive surgery, have multiple fractures, are septic, or have advanced cancer or acquired immunodeficiency syndrome. The client with the open cholecystectomy is not a candidate because this client would resume a regular diet within a few days following surgery.

A client has been discharged to home on parenteral nutrition (PN). With each visit, the home care nurse should assess which parameter most closely in monitoring this therapy? 1. Pulse and weight 2. Temperature and weight 3. Pulse and blood pressure 4. Temperature and blood pressure

2. Temperature and weight The client receiving PN at home should have her or his temperature monitored as a means of detecting infection, which is a potential complication of this therapy. An infection also could result in sepsis because the catheter is in a blood vessel. The client's weight is monitored as a measure of the effectiveness of this nutritional therapy and to detect hypervolemia. The pulse and blood pressure are important parameters to assess, but they do not relate specifically to the effects of PN.

The nurse is caring for a restless client who is beginning nutritional therapy with parenteral nutrition (PN). The nurse should plan to ensure that which action is taken to prevent the client from sustaining injury? 1. Calculate daily intake and output. 2. Monitor the temperature once daily. 3. Secure all connections in the PN system. 4. Monitor blood glucose levels every 12 hours.

3. Secure all connections in the PN system. The nurse should plan to secure all connections in the tubing (tape is used per agency protocol). This helps prevent the restless client from pulling the connections apart accidentally. A & B are correct but do not relate to safety. Glucose is checked q 4 hours.

A client receiving parenteral nutrition (PN) suddenly develops a fever. The nurse notifies the health care provider (HCP), and the HCP initially prescribes that the solution and tubing be changed. What should the nurse do with the discontinued materials? 1. Discard them in the unit trash. 2. Return them to the hospital pharmacy. 3. Send them to the laboratory for culture. 4. Save them for return to the manufacturer.

3. Send them to the laboratory for culture. When the client who is receiving PN develops a fever, a catheter-related infection should be suspected. The solution and tubing should be changed, and the discontinued materials should be cultured for infectious organisms. The other options are incorrect. Because culture for infectious organisms is necessary, the discontinued materials are not discarded or returned to the pharmacy or manufacturer.

The nurse is preparing to change the parenteral nutrition (PN) solution bag and tubing. The client's central venous line is located in the right subclavian vein. The nurse asks the client to take which essential action during the tubing change? 1. Breathe normally. 2. Turn the head to the right. 3. Exhale slowly and evenly. 4. Take a deep breath, hold it, and bear down.

4. Take a deep breath, hold it, and bear down. The client should be asked to perform the Valsalva maneuver during tubing changes. This helps avoid air embolism during tubing changes. The nurse asks the client to take a deep breath, hold it, and bear down. If the intravenous line is on the right, the client turns his or her head to the left. This position increases intrathoracic pressure. Breathing normally and exhaling slowly and evenly are inappropriate and could enhance the potential for an air embolism during the tubing change.
