1. Introduction 
Nurses are exposed to occupational injuries and stressors, and the psychological pressures caused by them endanger their health in the profession and the workplace [1]. In this regard, emergency department nurses are constantly experiencing stresses caused by emergencies and related factors related to the specific nature of their job. These stresses can affect the quality of their work and, consequently, the organization’s productivity [2]. Also, nurses in emergency departments experience many problems in the hospital environment, which cause emotional reactions and, consequently, increase individual and interpersonal problems in the workplace [3]. Appropriate communication between medical staff and patients and the seriousness and collective spirit in work are the moral aspects of nursing and the medical profession. These aspects reduce patients’ anxiety and worry and improve their treatment processes [4]. Therefore, one of the essential factors in nursing that can affect the therapeutic and health aspects of the workplace is moral distress [5]. 
Moral distress has been defined as a psychological imbalance and a state of negative emotion in which a person cannot change moral or professional decisions based on his or her knowledge into action and behavior. Sometimes distress is caused in response to facing individual barriers such as depression and anxiety and sometimes organizational barriers such as burnout and low job satisfaction so that a person cannot continue activity based on the primary moral distress and subsequent negative emotions [5]. Moral distress can have different consequences for both the patient and the nurse or the staff, and it can cause a feeling of losing control over environmental conditions and patient care in the treatment staff [6]. Also, studies have shown that moral distress affects low job attachment, burnout, the tendency to quit work, and patients’ dissatisfaction [7, 8].
Stress involves reactions toward one’s work environment and personal life, which can have both positive and negative effects on individuals [9]. Barzgar et al. [10]showed that job stress in nurses working in the emergency department is more than in other departments, which leads to their burnout. In examining the consequences of stress and its impact on work morale issues; the studies show that stress and stressful conditions create conflicting feelings, futility, indifference, and depression in nurses [11] that result in ethical issues such as reducing empathy with patients [12] and work ethics [13]. 
Emergency department nurses are exposed to serious risks and diseases related to their health due to constant contact with patients and frequent use of equipment [14]. They are constantly exposed to the risk of physical and mental illnesses and stress [15]. Persistent and intense health concerns characterize health anxiety, and in the diagnostic term, those who become disabling due to anxiety are diagnosed with hypochondriasis [16]. Concerning health anxiety and nursing staff, Myers et al. reported on the important consequences of job stress in such a way that 60% to 90% of emergency department nurses complain of physical illness [17]. Sirati, Karimi, and Khalili [18] concluded that coronavirus department nurses had tolerated much stress facing the epidemic of COVID-19 disease; this stress is concerned about health and death, and life, which have different consequences, including problems in work ethic.
Tolerance of turbulence is one of the concepts that can act as psychological protection against health anxiety and stress in emergency department nurses. Ellis et al. [19] defined tolerance of turbulence as the ability of an individual to experience and tolerate negative emotional states that can have a developmental and educational aspect. According to Ellis et al. [19], parents can determine this aspect of children’s upbringing and development by disregarding some of their needs. This structure is a variable of individual differences that refers to the capacity to experience and resist emotional distress [20]. Tolerance of turbulence is increasingly seen as an important structure in developing new insights about the onset and maintenance of psychological trauma and prevention and treatment [21]. Many reports have focused on the distinct concept of tolerance of turbulence among people with or at risk of psychological trauma [22]. Moqaddas and Khaleghi [23] achieved the relationship between tolerance of turbulence and moral intelligence in nurses. Also, according to the social components of moral distress, i.e., reducing the social relations between nurses in the emergency department, a study has shown the relationship between optimism and tolerance of turbulence with nurses’ moral distress [24].
The moral distress of emergency department nurses significantly affects their performance in the workplace and plays a decisive role in the level of service to patients and the medical system. So many stressful stimuli in the nursing workplace can affect clinical performance. For this reason, it is necessary and important to pay attention to the problems of emergency department nurses, especially moral issues, during the COVID-19 epidemics and the existence of many effective psychological stimuli. In this regard, the present study was conducted to determine the relationship between health anxiety and perceived stress with moral distress and mediation of distress tolerance in emergency department nurses. 

2. Materials and Methods 
This research is descriptive-correlational. The research population consisted of all nurses in the emergency department of Tehran in 2020, of whom 230 nurses who met the inclusion criteria were selected by convenience sampling method. Some studies [25] consider the acceptable number for descriptive research of path analysis type to be 200. Path analysis is a statistical method for applying the standard beta coefficients of multivariate regression in structural models. This analysis aims to obtain quantitative estimates of causal relationships between variables based on the assumptions of correlations and research background. Therefore, in this study, 230 people are considered to satisfy the desired statistical power and adequacy of sampling. Because of the COVID-19 epidemics and its limitations, an online questionnaire was used instead of a paper questionnaire. Because data collection was online, first, a link to the questionnaire and the request for cooperation were sent to the participants via email or WhatsApp. The data were then collected within a specified time.

Research tools 
Health anxiety questionnaire 

The health anxiety questionnaire was prepared by Salkowski and Warwick. This questionnaire is a self-assessment scale with 18 four-option expressions that describes a person’s position during the last 6 months in the best way. The expressions of this test are concerns related to health, paying attention to emotions or bodily changes, and the terrible outcomes of disease. Each expression is scored between 0 and 3. If a person selects more than one option, options with a higher score are selected for scoring [26]. In Iran, a study that examined the validity and reliability of this scale showed that the construct validity of this questionnaire includes three factors: disease, disease outcomes, and general health concerns. Also, the Cronbach α coefficient with a value of 0.75 showed the desirable validity of the questionnaire [27]. 

Distress Tolerance Scale (DTS)
The Distress Tolerance Scale (DTS) is a self-assessment scale that was developed by Simons and Gaher [28] and had 15 questions and 4 subscales. Its subscales are tolerance, absorption, evaluation, and adjustment, which are scored on a 5-point scale from 1=strongly agree, 2=slightly agree, 3=equally agree and disagree, 4=slightly disagree, to 5=strongly disagree. Higher scores indicate high distress tolerance [28]. Alpha coefficient in Basharpour et al. [29] research for these scores were 0.72, 0.82, 0.78, 0.70, and 0.82 for the whole scale, respectively. 

Moral distress questionnaire
Jameton moral perturbation scale (2009) is the first scale to measure moral distress in the healthcare community. The questionnaire consisted of 28 questions that measured the level of moral distress experienced by treatment staff in specific situations. The scoring of this tool was done using the 7-point Likert scale for levels of moral distress from very low to very high. The total score of the questionnaire ranges from 28 to 196; the higher the score, the greater the moral distress. The scientific validity and reliability of the tool of moral distress have been measured in an internal study, which has been determined by retesting and the Cronbach α value as 0.86 [30]. 

Perceived stress questionnaire
Perceived Stress Questionnaire was developed by Cohen, Kamarck, and Marmelstein [31] and had 3 versions of 4, 10, and 14 items that are used to measure the general stress perceived in the past month. This questionnaire is used when one wants to know to what extent a person›s life situations are stressful [31]. The questionnaire items are scored on a 5-point Likert scale from never=4 to very high=0. A higher score indicates more perceived stress. In the study conducted by Cohen et al. [31], the Cronbach α for this scale was 0.85.
Considering moral principles such as confidentiality of participants› information and their informed consent to enter and exit the research, the information obtained from the data is analyzed by statistical methods such as the Pearson correlation and path analysis in SPSS and Amos software. 

3. Results
About 75% of the nurses participating in the study were married, and 25% were single. Also, 39% had more than 10 years of work experience, 42% had more than 5 years, and 19% had less than 5 years of work experience. 
According to Table 1, the relationship between health anxiety and perceived stress with moral distress is positive and significant, but the relationship between distress tolerance and moral distress is negative and significant (P<0.01).

The results of the correlation matrix showed that the relationships between study variables are significant. Therefore, it is possible to review the model. Initially, the model fit indices were calculated (Table 2).

According to Table 2, the values of the Goodness Fit Index (GFI), Adjusted Goodness of Fit Index (AGFI), and Comparative Fit Index (CFI) are 0.97, 0.96, and 0.98, respectively, indicating that the model fits well with the data. If the CFI, AGFI, and GFI indices are higher than 0.90, it indicates a very appropriate and desirable fit, and a value higher than 0.80 indicates an appropriate and desirable fit. The Root Mean Square Error of Approximation (RMSEA) for the present study was 0.05, indicating the appropriate fit of the model with the data.
According to Figure 1 and Table 3, perceived stress and health anxiety have a positive and direct effect on moral distress, but distress tolerance has a negative and direct effect on moral distress (P<0.01).

Also, perceived stress and health anxiety have direct and adverse effects on distress tolerance (P<0.01). To investigate the mediating role of distress tolerance between perceived stress and health anxiety with moral distress, Bootstrap instruction was used (Table 4). As seen in Table 4, distress tolerance mediates between perceived stress and health anxiety with moral distress. 

4. Discussion 
We investigated the relationship between health anxiety and perceived stress with moral distress and mediating role of distress tolerance in emergency department nurses. The results showed that health anxiety and perceived stress have a positive and direct effect on moral distress in emergency department nurses. Our study result is consistent with the findings of other studies [11, 12, 13]. The psychological problems such as stress and depression caused by physical health concerns and health anxiety and death in emergency department nurses, if excessive, can lead to physical, psychological, behavioral, and even moral complications for the nurses and endanger their health and occupational environment. When the stress of work requirements (observation of mortality, the severity of illness) exceeds the threshold, even a small problem can become a psychological crisis and make it harder for a person to bear the problems. Fan et al., in a study, showed that moral distress in the workforce is strongly associated with symptoms of depression and anxiety, so the symptoms of depression and anxiety can increase the moral distress in the workforce [32].
The main results of the study show that distress tolerance has a mediating role in the relationship between health anxiety and stress with moral distress in emergency department nurses so that health anxiety and perceived stress have a positive effect on their moral distress by reducing nurses’ distress tolerance. This obtained result in our study is consistent with the findings of other studies [23, 24]. Also, the findings of this study are consistent with some studies that inversely show that the feeling of job security (lack of anxiety in the workplace) by using the appropriate coping mechanism, including distress tolerance, causes mental health and the workplace [33]. 
People who cannot tolerate stress and distress in stressful situations probably get involved in moral problems in the organization. Some findings indicate that mindfulness and cognitive regulation against health anxiety and stress can increase distress tolerance and reduce burnout, which is a significant cause of moral distress [34]. One study showed that distress tolerance reduced the risk of suicide due to firefighters’ job stress [35]. Distress intolerance reinforces avoidance behaviors against emotion and physical symptoms in people with health anxiety and stress that this strategy can be a threat to the nurses and all members of the treatment staff for their professional and moral performance [36].
Research results show that COVID-19 anxiety reduces stress management and greater vulnerability and reduces responsibility [37]. Therefore, health anxiety and stress in emergency department nurses who recently suffered from COVID-19 can reduce their tolerance to various aspects of workplace problems and make them vulnerable to moral problems and slips. On the other hand, among the consequences of the inability to manage stress in the work environment is a decrease in adherence to organizational ethics, resorting to behaviors that avoid work responsibilities, and communication disorders [13]. One of the limitations of this study was that it was performed on emergency nurses in Tehran, so the generalization of the results to other occupations and cities should be made with caution. 

5. Conclusion
This study confirms the mediating role of job distress in the relationship between health anxiety and perceived stress with the moral distress of emergency department staff. According to the findings, in addition to measures to reduce and manage health anxiety and stress and due to the inevitable nature of this anxiety, by strengthening the spirit of acceptance and tolerance of work environment distress, we should reduce the moral distress of these nurses in the work environment.
