This study was conducted at the French Group Company at Al-Sadat City in Menoufia Governorate. The hundred forty-eight fertile eggs were collected from 200 females of Pekin ducks (Anas platyrhynchos) at the age of (26 weeks of production), which mated by artificial insemination with 30 male of Muscovy ducks (Cairina moschata) to produce Molar ducks. Eggs were divided into four equal treatments (each of 96 eggs) and subjected to different storage periods (0, 4, 8 and 12 days) to determine the effects of different storage periods on egg weight loss, hatchability, hatch window, duckling quality, duckling immunity, and its body weight were measured for the different treatments. The results revealed that there were insignificantly differences (p ≤ 0.05) in egg weight loss by the different preincubation egg storage period. Storage eggs for 0 days had the highest hatchability percentage (92.2 %) compared to other experimental groups. Data demonstrated that storage eggs for 12 days achieved the largest hatch window (17:30 hours) when compared with 0, 4 and 8 days of storage. The relationship between storage period and duckling quality revealed that storage eggs for 0 days achieved the highest quality compared to the other groups. Immunity also, was affected by storage period (0 days was the highest immunity) compared with the other groups. The effect of storage period on duckling body weight at age of one day was also studied. Data indicated that third group (storage periods 8 days) achieved significantly (P ≤ 0.01) highest body weight (76 g). It could be concluded that storage of fertile duck eggs should not exceed 8 days to avoid excessive loss of egg water that impair the albumen contents which needed by the developing embryo for growth during incubation. The storage also, affected the transfer of maternal immunity to the embryos and the hatched ducklings.

Background: Cardiogenic shock resulting of an inadequate circulation of blood due to primary failure of the ventricles of the heart to function effectively. As this is a type of circulatory shock, there is insufficient perfusion of tissue to meet the demands for oxygen and nutrients. Cardiogenic shock is a largely irreversible condition and as such is more often fatal than not. The condition involves increasingly more pervasive cell death in oxygen starvation (hypoxia) and nutrient starvation (e.g. low blood sugar). Because of this, it may lead to cardiac arrest (or circulatory arrest), Nurses, physicians and others health team need to work together to develop a rapid and well-organized treatment approach to this devastating condition. Objective: The present study aimed to assess the effectiveness of an educational program on nurse's knowledge concerning management of cardiogenic shock. Methodology: A quasi-experimental design study was carried out at AL-Mosul teaching hospitals in March 9th 2015 to July 1st of 2015. The program and instruments constructed and developed by the researcher to measure the purpose of the study. Random sample comprised of (50) nurse was divided into two groups, study group consisted (25) nurse exposed to the nursing educational program and control group consisted (25) nurse were not exposed to the program. The measurement of the effectiveness of nursing educational program on nurses' knowledge the researcher use knowledge test includes (44) items concerning with assessment knowledge for nurses related to management of patients with cardiogenic shock. Reliability of instrument tools was determined through the use of test and retest and the instrument validity was determined through a panel of experts. The analysis of data was performed through the application of description statistic (Frequencies, Percentages, and cumulative percent, Mean of Score, Standard Deviation, Relative Sufficiency) and Inferential statistical (Chi-Square test, Fisher Exact Probability test to present the differences between the study and control groups). Results: The results of the study showed that there is good improvement with highly significant differences in study group between pre and post tests in overall main domains. for the nurses' knowledge. Conclusion: The study Concluded that that inadequate nurses' knowledge in the medical department (coronary care unit, medical ward and emergency department) toward management of patient with Cardiogenic shock. Recommendation: The study recommended that an educational program can be designed and constructed for nurses through the program ,an emphasis can be directed and oriented in management of patient with Cardiogenic shock should be included continuous training for all nursing staff who work in medical department(coronary care unit, medical ward and emergency department).
