Final answer:
The most useful theory category for a nurse beginning IV therapy is Clinical Focus, incorporating the practical application of physiological knowledge and sterile techniques.
Step-by-step explanation:
A nurse preparing to begin intravenous fluid therapy for a patient would find the category of theory known as Clinical Focus most helpful. Initiating IV therapy requires understanding the physiology
involved in fluid and electrolyte balance, knowledge of sterile procedures to prevent infection, and the ability to use clinical judgment to assess the patient's immediate needs.
For a dehydrated patient, the nurse might administer a solution like normal saline or lactated Ringer's solution, which are isotonic and thus important for maintaining the equilibrium of fluid in the patient's .
cells and blood vessels. In emergency situations such as hypokalemia, a specific solution, such as 0.5% KCl, would be used to correct the deficiency. It's essential to apply rigorous clinical .
standards because infections like those caused by Staphylococcus epidermidis can occur, demanding conscientious medical attention and sometimes a change in treatment, such as the shift .
