This is always a grouping problem. For this the best way is using the
Muenchian Method: http://www.jenitennison.com/xslt/grouping/muenchian.html.

You have to group your <OBX> by the Observation_ID:

<xsl:key name="obx" match="OBX" use="@Observation_ID"/>

<xsl:template match="tdObsResults">
    <xsl:apply-templates select="OBX[count( . | key( 'obx',
@Observation-ID)[1] ) = 1]"/>

<xsl:template match="OBX">
    <xsl:value-of select="@Observation_ID"/>
