While caring for a client receiving total parenteral nutrition (TPN), it is most important for the nurse to monitor which of the client's lab values?

Serum protein.

Serum osmolarity.

Urinary ketones.

Capillary glucose.

Answer and Explanation

The Correct Answer is D

A. Serum protein is an indicator of the client’s overall nutritional status, but it is not as immediately critical to monitor as glucose levels in clients receiving TPN. Protein levels change more slowly over time and are not an acute concern.

B. While serum osmolarity is important in evaluating hydration status and electrolyte balance, it is not the primary lab to monitor during TPN administration. Glucose fluctuations are more likely to cause immediate complications.

C. Urinary ketones are typically monitored in clients with diabetic ketoacidosis (DKA), not in clients receiving TPN. Ketones are a byproduct of fat metabolism and are not a priority in TPN management.

D. Capillary glucose is the most important lab to monitor in clients on TPN because TPN solutions contain high amounts of glucose, which can lead to hyperglycemia. Monitoring glucose levels helps prevent complications such as hyperglycemia or hypoglycemia and is critical in managing the client's metabolic response to TPN.

Correct Answer is ["A","C","D"]

Explanation

Choice A: Positioning the client in the left lateral recumbent position allows the solution to flow by gravity into the sigmoid colon and rectum.

Choice B: Chilling the enema solution is not recommended because it can cause cramping, discomfort, and vasoconstriction, which may interfere with the client's fever assessment.

Choice C: Positioning the client in the left lateral recumbent position allows the solution to flow by gravity into the sigmoid colon and rectum.

Choice D: Inserting the lubricated tip of tubing 3 to 4 inches into the rectum prevents injury to the rectal mucosa and ensures proper placement of the tubing.

Choice E: Clamping the enema administration tubing after filling the enema bag is unnecessary and may cause air to enter the tubing, which can increase the risk of abdominal distension and gas pain.

A. Complete blood count. B. Serum troponin levels. C. Creatinine clearance. D. Prothrombin time (PT)

Correct Answer is D

Explanation

Choice A: A complete blood count (CBC) is important for monitoring various aspects of the blood, including the number of red blood cells, white blood cells, and platelets. While important for assessing overall health, a CBC is not the primary laboratory finding used to assess the effectiveness of warfarin in managing atrial fibrillation.

Choice B: Serum troponin levels are typically measured to assess cardiac muscle damage, such as in myocardial infarction (heart attack). They are not the primary indicator for assessing the effectiveness of warfarin in atrial fibrillation.

Choice C: Creatinine clearance is a measure of kidney function and is not the primary laboratory finding used to evaluate the effectiveness of warfarin.

Choice D: Prothrombin time (PT) is the most relevant laboratory finding for monitoring the effectiveness of warfarin in clients with atrial fibrillation. Warfarin's therapeutic effect is primarily assessed through PT measurements, with the goal of maintaining the client's international normalized ratio (INR) within a specific target range to prevent excessive bleeding or clotting.
