The client's 8-hour urine output is 400 ml, blood urea nitrogen (BUN) is 15 mg/dl (5.355 mmol/L), lungs are clear bilaterally, serum glucose is 110 mg/dl ( 6.1 mmol/L), and serum potassium is 3.7 mEq/L (3.7 mmol/L). Which action should the nurse implement?
Document in the medical record that these normal findings are expected outcomes Rationale The results are all within normal range (BUN 10 to 20 mg/dl or 3.6-7.1 mmol/L (SI units), serum glucose 70 to 110 mg/dl or less than 6.1 mmol/L (SI), and serum potassium 3.5 to 5.0 mEq/L or 3.5-5.0 mmol/L (SI units). The other actions are not indicated.
A client's IV infusion of 0.9% Sodium Chloride (normal saline) infiltrated earlier today, and approximately 500 ml of normal saline infused into the subcutaneous tissue. The client is now complaining of excruciating arm pain and demanding "stronger pain medications." What action is most important for the nurse to take?
Measure the pulse volume and capillary refill distal to the infiltration Rationale Compartment syndrome occurs when external pressure (usually from a cast), or internal pressure (usually from subcutaneous infused fluid), exceeds capillary perfusion pressure resulting in decreased blood flow to the extremity. The most important action is to assess pulse volume and capillary refill distal to the infiltration site toetermin d loss of the peripheral pulse in the extremity, which is evidence of compartment syndrome. The other actions are of less priority than determining the effects of the infiltrate fluids on circulation and nerve function.
The nurse is caring for a client who is receiving 24-hour total parenteral nutrition (TPN) via a central line at 54 ml/hr. When initially assessing the client, the nurse notes that the TPN solution has run out and the next TPN solution is not available. What immediate action should the nurse take?
Infuse 10% dextrose and water at 54 ml/hour Rationale TPN should be discontinued gradually to allow the client to adjust to decreased levels of glucose. Administering 10% dextrose in water at the prescribed rate should reduce the client's risk of hypoglycemia until the next TPN solution is available. The other actions are not indicated.
A client is receiving a cephalosporin antibiotic IV and complains of pain and irritation at the infusion site. The nurse observes erythema, swelling, and a red streak along the vessel above the IV access site. Which action should the nurse take?
Initiate an alternate site for the IV infusion of the medication Rationale A cephalosporin antibiotic that is administered IV may cause vessel irritation. Rotating the infusion site minimizes the risk of thrombophlebitis, so an alternate infusion site should be initiated before administering the next dose. The other actions are not indicated.
What action should the nurse implement when accessing an implanted infusion port for a client who receives long term IV medications?
Insert a huber-point needle into the port Rationale An implanted infusion port needs to be accessed using a Huber-point needle (non-coring) to be prevent damage to the self-sealing septum of the port. The other actions are not necessary when accessing an implanted infusion port.
