Final answer:
Clients receiving Total Parenteral Nutrition (TPN) and who are NPO require regular monitoring of their capillary blood glucose levels, and insulin injections are part of their routine care. These measures are necessary to manage blood glucose levels effectively.
Step-by-step explanation:
The accurate monitoring of capillary blood glucose levels is particularly important in clients receiving Total Parenteral Nutrition (TPN) because they are not eating by mouth (NPO), and their blood glucose levels can fluctuate due to the high glucose content in TPN solutions. Nurses need to administer insulin injections as necessary to manage these levels and ensure normal metabolism and energy usage in the body. This is done before meals (AC; ante cibum) and at bedtime (HS; hora somni). While these injections do not increase blood glucose levels, they help the body store and utilize glucose more effectively.
Regarding the statement about capillary blood glucose measurements being prescribed for a patient on TPN and NPO, such monitoring is indeed standard practice to prevent potential complications from hyperglycemia. Therefore, it is accurate to affirm that a nurse would have a prescription to monitor blood glucose levels AC and HS for a client on TPN and NPO.
