2. Observation and monitoring of the patient's response to care and treatment
Observation is a skilled nursing service when the unstabilized condition of the patient requires the skills of a licensed nurse to detect and evaluate the patient's need for possible modification of treatment or institution of medical procedures. For example, pending stabilization of the condition, a patient suffering from arteriosclerotic heart disease may require close observation by skilled nurses for signs of decompensation and loss of fluid balance in order to determine whether the digitalis dosage should be changed or other therapeutic measures should be taken.
Similarly, in some cases, surgical patients (including postoperative cataract patients) are transferred from a hospital to an SNF while still in the immediate unstabilized postoperative period during which the possibility of adverse reaction to anesthesia and other aspects of the operative procedure necessitates close skilled monitoring.
