The nurse provides care for a client who is severely malnourished. A central venous access device (CVAD) is placed to administer total parenteral nutrition (TPN). Which laboratory result does the nurse closely monitor?
Glucose
Cholesterol
Hemoglobin
Sedimentation rate
The Correct Answer is A
Total parenteral nutrition (TPN) is a form of nutrition that is administered intravenously when a client is unable to eat or absorb nutrients orally or enterally. TPN solutions contain a high concentration of glucose, which provides the body with energy. Therefore, the nurse must closely monitor the client's glucose levels, as TPN can cause hyperglycemia (high blood sugar levels).
Frequent monitoring of blood glucose levels is necessary to ensure that the client's blood sugar stays within an acceptable range. Hyperglycemia can lead to a variety of complications, including dehydration, electrolyte imbalances, and damage to organs such as the kidneys and eyes. If the client's blood glucose levels are consistently high, adjustments to the TPN solution may be necessary, or insulin may need to be administered to help regulate blood sugar levels.
Therefore, glucose is the laboratory result that the nurse must closely monitor when a client is receiving TPN via a central venous access device (CVAD).

Correct Answer is A
Explanation
A rectal temperature should not be taken if the client has bradycardia because stimulation of the vagus nerve during the insertion of the rectal thermometer can result in a further decrease in heart rate. Hypertension, tachypnea, and pyrexia are not contraindications for taking a rectal temperature.
Correct Answer is ["A","C","E","I","J"]
Explanation
The nurse should gather primary IV tubing, antiseptic wipes such as chlorhexidine, an intravenous access device, appropriate lab specimen tubes, and appropriate lab specimen labels. These supplies are necessary for drawing lab work, starting an IV, and collecting lab specimens.
Sterile gloves and a tourniquet are not needed for drawing lab work or starting an IV in this situation, as clean gloves are sufficient for these tasks. A bag of ice is not indicated for this client's current assessment findings. 0.9% NS intravenous fluids are not mentioned in the scenario, so it is unclear whether they are needed at this time.
