Knowledge of hypertension by hypertensive patients is important for them to maintain optimal health, prevent complications and live a productive life. There is a direct relationship between a patients’ knowledge and the management of their illnesses.  Majority of hypertensive patients are having complications due to poor knowledge of hypertension.  Nurses as expert in health education are expected to influence patients’ self-care of hypertension through increase in knowledge. Therefore, this study assessed the effect of a nurse- led intervention on knowledge of hypertension among patients in Baptist Medical Centre (BMC), Saki, Oyo State. The study design was a one group pre-test post-test quasi experimental design. The study took place at Baptist Medical Centre, Saki with one hundred and thirty three (133) respondents. Total enumeration sampling techniques was used to select the 133 participants for this study. The instrument for data gathering for this study was a test paper. Content and face validity of the research instrument were ensured by experts in the field of nursing science. The reliability coefficient value of the items that measures “Knowledge of Hypertension” was 0.803. Data was presented using descriptive statistics (percentages and mean) while inferential statistics (t-test) was used to test the hypothesis. The study showed that pre-intervention knowledge mean score of respondents on hypertension was 4.03 (40.3%), which was low while post intervention knowledge mean score was 7.41(74.1%), which is high. In conclusion, the study established that there is a significant difference in the pre and post mean score of knowledge level on hypertension. The study recommended among others that intensive awareness through health education and information sharing needs to be advocated from a health perspective on hypertension to inform and educate the public at large.
