Pressure sore have been considered as a major health care problem. Nurse's knowledge about factors related to pressure ulcer can decrease pressure ulcer. The aim of this study was to determine factors associated with pressure sore in patients admitted to the orthopedic ward. In this descriptive study, 330 patients from four orthopedic units of Shahid Beheshti University of Medical Sciences were selected by convenience sampling method. The data was collected by using "Nursing Care Observation Form". The form was validated by content validity method and inter-rater agreement method was used for reliability (Correlation Coefficient=0.85). Data were analyzed by SPSS/15. Many factors such as; attendant, training in regard to prevention of pressure sore, massage, changing patient position, skeletal traction, moving aid, external objects in bed, trapeze and floating map had significant statistical correlation to pressure sore (P<0.05). In Logistic Regression Model "have no attendant" was the most important factor of pressure sore (P<0.01). Many factors can cause pressure sore in the hospitalized patients. Therefore, teaching of students and healthcare providers about pressure sore care related factors and the necessity of applying pressure sore prevention in at risk patients before the ulceration is very important.

Hypertension is the most common risk factor for cardiovascular disease in elderly. This study aimed to determine the effect of short-term aerobic exercise on blood pressure in elderly with hypertension. In this clinical- trial controlled study، 92 elderly clients with the age of 65-75 years were selected in Shiraz city، Iran، in 2011، according to inclusion criteria of study and divided into two equal groups of control and intervention. The intervention consisted of 4-week walking periods، three times in one week، each time 20-30 minutes. Data were collected using calibrated mercury sphygmomanometer. The Reliability of mercury sphygmomanometer was confirmed by intra-rater consistency. The data were analyzed using paired and independent t test via SPSS 16 software. There was no statistically significant difference between the groups in means of systolic and diastolic blood pressures before intervention. After the intervention، mean of systolic blood pressure decreased significantly from 149. 88 ± 4. 16 to 144. 93 ± 5. 21 (P = 0. 004) and diastolic blood pressure decreased significantly from 94. 03 ± 3. 16 to 85. 9 ± 6. 38 (P = 0. 030) in intervention group; but there was no significant change in control group. The findings showed that walking is an effective nursing intervention for reducing blood pressure in elderly patients with hypertension.
