In "Follow The 3 Ws To Accurately Track Ambulation Improvement" (OASIS Alert v11n12), the response given for Scenario C is 0; however, the reasoning for that answer applies to Scenario D. Clarification: In the case of Scenario C, the patient relied on a walker (two-handed device) to ambulate safely. Therefore, the score for this item should be 2 (Patient needs a two-handed device on level surfaces and/or another person present on uneven surfaces or stairs).
