Nursing Interventions
Nursing Guide
The guide is designed to
1)
Identify symptoms that may indicate a
side effect related to DRTB treatment
or antiretroviral medication
2)
Assess for severity as well as other
potential contributors
3) Intervene appropriately to minimize
patient discomfort, reduce side effect
progression, and ultimately support
