This article describes the emergency nursing care of a middle-aged man who travelled to the Philippines and was accidentally bitten on the right arm by unidentified marine organisms while diving. He then developed marine vibrio infection complicated with septic shock. The nursing period lasted from October 20 to October 22 2017, with Gordon's 11 Functional Health Patterns applied to the evaluation framework using physical assessment, observation, medical chart reviews, and written communications. The main symptoms of the patient were tissue perfusion alterations, pain, and anxiety. The author used patience, empathy, listening, and concern to establish the patient's spiritual and mental needs and help him participate in the care activities with the emergency care team properly and carefully. We provide concrete and detailed application as well as individualized nursing care, such as oxygenation, appropriate antibiotics, vessel contracture agent therapy, respect and encouragement of religious behaviors, and prayer to reduce anxiety. Allowing the patient to participate in care decision-making increases self-confidence, and the patient's symptoms eventually improved whose health were gradually getting better. Taiwan is a subtropical island country. Marine activities and seafood consumption are common among Taiwanese people; therefore, the mortality rates for Vibrio anguillarum infection are extremely high. As a result, discussion and sharing of the motivation of nursing experience with colleagues and take it as a reference for clinical care in the future.
