This shows a significant result, but the researchers considered that the intervention group had a more significant value when compared to the control. Likewise, the diastolic blood pressure in which the control group was obtained p-value 0.051 (> 0.05) while the intervention group obtained p value of 0.000 (<0.05). Conclusion: There was no significant difference in blood pressure in the group, control use media short message service (SMS). While the intervention group showed a very significant difference between before and after telenursing used media WhatsApp]]>
