Hypertension has a high morbidity and mortality and studies had revealed that knowledge on hypertension was generally low, and self-care management practice was just at moderate level. Therefore, this study assessed the effect of nurse-led intervention on knowledge of self-care management of hypertension among retirees attending geriatric clinic in LASUTH, Lagos State. One group pre-test, post-test quasi-experimental design was used for the study. A convenience sampling technique was used to select 100 participants for the study. Data were collected with the use of self-developed questionnaire which was used for both pre and post-intervention data collection. Face and content validity of the questionnaire were ensured by experts in the nursing science. Two hypotheses were tested using inferential statistics of paired t-test at 5% level of significance. The pre-intervention knowledge mean score of participants on the knowledge of hypertension was poor (mean = 7.37; 36.9%) while at post intervention was Good (mean = 15.91; 79.6%). Also, the pre-intervention knowledge of self-care management of hypertension mean score was fair (mean = 6.42; 40.1%) while at post intervention was good (mean = 12.60; 78.8%). The findings further showed there is a significant difference between the pre and post intervention knowledge of hypertension among retirees (Mean difference = 8.54, t₍₁₈₀₎ = 25.25, p = .00). A significant difference was equally found between the pre and post intervention knowledge of self-care management of hypertension (Mean difference = 6.19, t₍₁₈₀₎ = 17.40, p = .00). In conclusion the nurse-led intervention improved knowledge of hypertension and knowledge of self-care management among retirees attending geriatric clinic in LASUTH. It was recommended that patient’s knowledge level regarding hypertension should be assessed, and proper education should be provided, and educational material should be given by the Nurses.
