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?

Urinary ketones.

Serum protein.

Serum osmolarity.

Capillary glucose.

Answer and Explanation

The Correct Answer is D

Correct answer: D

Choice A

Urinary ketones are not most important. Monitoring urinary ketones can provide information about the utilization of glucose and fat as energy sources. However, it is not the primary lab value to monitor in TPN administration.

Choice B

Serum protein is not most important. Monitoring serum protein levels is important to assess nutritional status, but it might not be as immediate a concern as serum osmolarity.

Choice C

Serum osmolarity reflects the concentration of particles (such as electrolytes, glucose, and other solutes) in the blood. Monitoring serum osmolarity is important to prevent complications related to fluid and electrolyte imbalances that can arise from the administration of TPN. Blood glucose levels (option D) are more critical because TPN can significantly impact glucose metabolism

Choice D

When caring for a client receiving total parenteral nutrition (TPN), the nurse’s priority is to monitor blood glucose levels. TPN can affect blood glucose, and observing for signs of hyperglycemia or hypoglycemia is crucial. Additionally, administering insulin as directed based on blood glucose levels is essential.

Correct Answer is B

Explanation

Choice A

Apples and blueberries are incorrect. While apples and blueberries are sources of nutrients, they are not as high in potassium as avocados and bananas.

Choice B

Avocados and bananas are correct. Chronic kidney disease (CKD) often requires dietary modifications to manage electrolyte and mineral imbalances. In CKD stage 4, the kidney's ability to filter waste and excess substances from the blood is significantly impaired. Therefore, certain foods that are high in potassium should be limited to prevent hyperkalaemia (elevated blood potassium levels).

Choice C

Cherries and cranberries are incorrect. Cherries and cranberries are also sources of nutrients, but their potassium content is not as high as that of avocados and bananas.

Choice D

Carrots and green beans are incorrect. Carrots and green beans are vegetables that are generally lower in potassium compared to fruits like avocados and bananas.

A. Serum HDL (high-density lipoprotein) of 35 mg/dl (0.91 mmol/L). B. Serum HbA1c (glycosylated haemoglobin) of 4.8% (0.05). C. BMI (body mass index) of 22 kg/m2. D. Total serum calcium of 10 mg/dl (2.5 mmol/L).

Correct Answer is A

Explanation

Choice A

Serum HDL (high-density lipoprotein) of 35 mg/dL (0.91 mmol/L). Among the options provided, a serum HDL level of 35 mg/dL (0.91 mmol/L) is the assessment data that indicates the need for referral to a nutritionist. HDL is often referred to as "good" cholesterol because it helps remove excess cholesterol from the bloodstream, reducing the risk of cardiovascular disease. In this case, the HDL level of 35 mg/dL is below the recommended reference range for females (greater than 55 mg/dL or greater than 0.91 mmol/L), which could suggest a potential need for dietary and lifestyle interventions to improve cardiovascular health.

Choice B

Serum HbA1c (glycosylated haemoglobin) of 4.8% (0.05) is incorrect. This HbA1c level is within the normal reference range (4% to 5.9%) and indicates good blood sugar control.

Choice C

BMI (body mass index) of 22 kg/m² is incorrect. A BMI of 22 is within the normal weight range and might not necessarily indicate the need for a nutritionist referral.

Choice D

Total serum calcium of 10 mg/dL (2.5 mmol/L) is incorrect. This calcium level is within the normal reference range and might not require a nutritionist referral, unless there are other specific concerns related to calcium intake.
