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.
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 B
Explanation
Choice A: Oranges are a good source of vitamin C, which is important for overall health, but they are not the primary dietary source for preventing rickets.
Choice B: Fortified milk is the best dietary source for preventing rickets because it is enriched with vitamin D, which is essential for calcium absorption and bone health. Vitamin D helps prevent rickets by promoting the absorption of calcium and phosphate in the body, which are necessary for proper bone development.
Choice C: Bananas are a good source of potassium but are not a primary dietary source for preventing rickets.
Choice D: Apple juice is not a primary dietary source for preventing rickets. While it may provide some vitamins and minerals, it is not directly associated with preventing this condition.
Correct Answer is D
Explanation
Choice A: Hematocrit is a measure of the proportion of blood volume occupied by red blood cells. While it can provide information about anemia or dehydration, it is not typically the first consideration in evaluating numbness and tingling in the extremities.
Choice B: Reviewing albumin and protein levels may be important for assessing overall nutritional status and potential causes of neuropathy but is not the immediate priority when a client reports numbness and tingling in the extremities.
Choice C: White blood cell count (WBC) is important for assessing immune function and the presence of infections. However, it is not typically the primary focus when evaluating numbness and tingling in the extremities.
Choice D: Electrolytes, such as serum sodium and potassium levels, are crucial to review when a client reports numbness and tingling in the extremities. Abnormal electrolyte levels can lead to neurological symptoms, and a review of electrolyte levels can help identify potential causes.
