Answer:
The correct answer is b. Continuous Infusion.
Step-by-step explanation:
TPN is a life-saving strategy that provides necessary nutrition and fluids to critically ill and malnourished patients who are unable to eat or digest meals orally. The best way to provide TPN to a severely ill and malnourished patient is a continuous infusion, out of the options offered. A continuous infusion of TPN offers a consistent supply of nutrients and fluids over a long period of time, often 24 hours per day. This approach provides for more exact control over the amount of nutrients and fluids supplied, which is especially significant in critically sick patients with unpredictable fluid and electrolyte needs. It also helps to maintain stable blood sugar levels and prevent hypoglycemia.
Bolus infusions, in contrast, might not supply enough nutrients and fluids throughout the day and might cause blood sugar levels to fluctuate. Cyclic infusions alternate between infusion and non-infusion periods, which can be difficult to control and may not give nutrients consistently. Prn infusions are only appropriate for patients who need medication only when they actually need it, as opposed to a constant supply of nutrition and fluids. Since gravity infusions do not offer exact control over the quantity of nutrients and fluids supplied, they are not advised for use in the administration of TPN.
