Final answer:
The student nurse's incorrect action is prescribing herbal supplements without consulting a healthcare provider. Other methods such as deep breathing, providing a calm environment, and recommending exercise are proper stress reduction techniques.
Step-by-step explanation:
The action of the student nurse that needs correction while providing stress reduction techniques to a patient is prescribing herbal supplements without consulting the healthcare provider. Nurses are not typically authorized to prescribe medications or supplements, as this falls under the purview of licensed medical doctors or qualified healthcare providers. Encouraging practices such as deep breathing exercises, providing a calm environment, and recommending regular exercise are beneficial stress reduction techniques backed by scientific research. Effective stress management often includes staying physically active, practicing relaxation methods like meditation or yoga, and ensuring a supportive environment, as detailed by researchers such as Herbert Benson and in studies reported by the Work: Journal of Prevention, Assessment, and Rehabilitation.
