Answer to Question 2
B
Discharge documentation includes medications, diet, community resources, follow-up care, and whom to contact in case of an emergency or for questions. A patient's acuity level, usually determined by a computer program, is based on the type and number of nursing interventions (e.g., intravenous IV therapy, wound care, ambulation assistance) required over a 24-hour period. Acuity level can be used for staffing and billing. Some institutions use standardized care plans to make documentation more efficient. The plans, based on the institution's standards of nursing practice, are preprinted, established guidelines used to care for patients who have similar health problems. In some settings, a Kardex, a portable flip-over file or notebook, is kept at the nurses' station. Most Kardex forms have an activity and treatment section and a nursing care plan section, which organize information for quick reference.
