Reciprocal altruism leads us to help others now with the expectation those others will return the favor should we need their help in the future order proventil 100 mcg with amex. The outcome of the reinforcement and modeling of altruism is the development of social norms about helping generic proventil 100mcg without a prescription, including the reciprocity norm and the social responsibility norm. Latané and Darley‘s model of helping proposes that the presence of others can reduce noticing, interpreting, and responding to emergencies. Aggression is activated in large part by the amygdala and regulated by the prefrontal cortex. Aggression is also caused by negative experiences and emotions, including frustration, pain, and heat. As predicted by principles of observational learning, research evidence makes it very clear that, on average, people who watch violent behavior become more aggressive. The social norm that condones and even encourages responding to insults with aggression, known as the culture of honor, is stronger among men who live or were raised in the South and West than among men who are from or living in the North and East. We conform not only because we believe that other people have accurate information and we want to have knowledge (informational conformity) but also because we want to be liked by others (normative conformity). The typical outcome of conformity is that our beliefs and behaviors become more similar to those of others around us. Studies demonstrating the power of conformity include those by Sherif and Asch, and Milgram‘s work on obedience. Although majorities are most persuasive, numerical minorities that are consistent and confident in their opinions may in some cases be able to be persuasive. Zajonc explained the influence of others on task performance using the concept of physiological arousal. When the outcome of group performance is better than we would expect given the individuals who form the group, we call the outcome a group process gain, and when the group outcome is worse that we would have expected given the individuals who form the group, we call the outcome a group process loss. Process losses can be reduced by better motivation and coordination among the group members, by keeping contributions identifiable, and by providing difficult but attainable goals.

In addition, they tended to be driven by examples rather than by theories or models which made them difficult to turn into lectures (from my perspective) or to use for essays or revision (from my students perspective). I also wanted to emphasize theory and to write the book in a way that would be useful (‘easily plagiarized’ I often think! Aims of this new third edition This third edition started as a quick update but has ended up as a fairly major revision. Health psychologists sometimes refer to the indirect and direct pathways between psychology and health. The indirect pathway refers to the role of factors such as health related behaviours (smoking, drinking, eating, etc. To date this book has mostly reflected this indirect pathway with its emphasis on beliefs and a range of health behaviours. These chapters have always been the strongest and have presented the theories and research in greatest depth, probably reflecting my own research interests. In contrast, the direct pathway refers to the role of factors such as stress and pain and draws upon the more biologically minded literatures. The first chapter (Chapter 10) examines models of stress, stress and changes in physi- ology and how stress is measured. It includes a review of the literature on whether stress does result in illness and describes research which has explored how this association might come about. This chapter also describes the role of coping, social support, control and personality in moderating the stress illness link. I have included more work on how psychological factors may exacerbate pain perception and have detailed the recent reviews of pain management and the interesting work on pain acceptance. The structure of the third edition Health psychology is an expanding area in terms of teaching, research and practice. Health psychology teaching occurs at both the undergraduate and postgraduate level and is experienced by both mainstream psychology students and those studying other health- related subjects. Undergraduates are often expected to produce research projects as part of their assessment, and academic staff and research teams carry out research to develop and test theories and to explore new areas. Such research often feeds directly into practice, with intervention programmes aiming to change the factors identified by research. This book aims to provide a com- prehensive introduction to the main topics of health psychology. In addition, how these theories can be turned into practice will also be described. This book is now supported by a comprehen- sive website which includes teaching supports such as lectures and assessments.

Other than relaxing respiratory rates purchase proventil 100 mcg on-line, no physiological benefits were observed order 100mcg proventil fast delivery, but, when interviewed five days later, patients who had received the neroli oil massage reported psychological benefits. Likely (but unproven) physiological benefits include improved lymphatic drainage, returning plasma proteins to the circulation. Reflexology Although there are ancient precedents, modern Western reflexology derives from the work of William Fitzgerald, a nineteenth-century doctor who accidentally found that the Intensive care nursing 442 use of pressure could replace anaesthesia during minor operations (Griffiths 1995). Fitzgerald believed that organ malfunction resulted in tiny crystalline deposits of calcium and uric acid on the nerve endings of the feet, and that breaking down these deposits with massage would heal the organ (Griffiths 1995). Fitzgerald identified ten energy zones of life-force running longitudinally through the body (not too dissimilar to the twelve meridians of Ki), reflecting the organs in specific parts of the feet (and hands). Reflexologists can therefore treat any part of the body using specialised foot massage that breaks down the crystalline deposits. If reflexology’s assumptions are correct, it is possible that nurses manipulating feet and hands (e. Griffiths (1995) warns that reflexology initiates a ‘healing crisis’ which can last up to 24 hours, although this is less likely to occur with the gentler Western approaches than the more vigorous approaches used in the East. The absence of any reported complications suggests this may not be an actual problem, but it leaves a (currently) unanswered question. Shiatsu Although derived from the Japanese for ‘finger pressure’, Shiatsu practice has gained wider connotations; it usually treats the whole meridian system (of vital energy/life force) in order to harmonise Ki (Stevensen 1995). Like other variants of massage, shiatsu is best left to those with specialist knowledge. Aromatherapy Aromatherapy implies the use of essential oils with direct chemical effects, not just burning something which emits pleasant smells (although boundaries between pleasure and therapy can become blurred when evaluating psychological benefit): burning neroli (see Massage above) can reduce anxiety. As active chemicals, essential oils can be considered to be drugs, albeit not restricted by regulations governing traditional medicines. Because of the nature of this therapy, the effects of aromatherapy may affect anyone (staff, other patients) in the immediate environment, so although relaxation may help some patients, it could be harmful to others, while possibly reducing staff efficiency. Complementary therapies 443 Placebo effect Throughout history significant minorities of people have benefited from inactive medicines (placebos); Hippocrates was familiar with the problems of patients who had been given unhelpful (and often harmful) treatments. Complex interactions between human physiology and psychology can make it difficult to ascribe a particular effect to a particular cause. When evaluating any treatment (complementary or orthodox), placebo, rather than active components, can benefit 35–52 per cent of patients (French 1989). Double-blind trials are designed to identify the extent of placebo effects, thus measuring whether any significant further benefit is gained from active ingredients. However, the value of quantitative research methodology for qualitative interventions is questionable. With their focus on the health of the whole person, rather than dysfunction of single organs, complementary therapist-client time typically exceeds the amount of time doctors can afford to spend with the majority of their patients. Thus, the benefits claimed for complementary therapies may result from prolonged human interaction rather than from active treatment. If nursing and touch are in themselves therapeutic, then benefits from many complementary therapies may be largely or solely due to nursing touch, rather than specific interventions. If the desired end effect of nursing is the comfort (in its widest sense) of patients and relatives, then utilitarian ethics can justify whatever means are used to gain that end. However, deliberate misinformation (such as injecting water instead of analgesia) breaks duty-based codes, and is (at best) ethically dubious. Nurses should therefore know what they are giving, the likely effects and, ideally, follow informed consent from their patients. While placebos can produce significant beneficial effects, their use raises many ethical problems. Nursing traditionally values ‘doing’; complementary therapies provide sets of actions, which may provide nurses with a sense of achievement (placebo) regardless of actual patient benefit. Anecdotally, many complementary therapies appear beneficial, but they need to be rigorously and objectively tested against placebo effects. Some complementary therapies rely on active chemicals (endogenous or exogenous), so that the effects of Intensive care nursing 444 interactions with other therapeutic drugs should be discussed. Most complementary therapies require the dedication of significant periods of time. If sufficient time cannot be allocated, it may be irresponsible to begin interventions that (knowingly) will not be completed. Nurses intending to practise complementary therapies should therefore ensure that they have sufficient time to complete their intervention. Interest in complementary therapies has created some (as yet) unresolved questions for nursing, such as: ■ What is treatment?

A single dog bite can produce up to 220 psi of crush force in addition to the torsional forces as the dog shakes its head purchase 100 mcg proventil with mastercard. Rates and Risks of Infection An estimated 10–30% of dog bites and 9–50% of human bites lead to infection order proventil 100 mcg with amex. Compare this with an estimated 1–12% of nonbite wounds managed in accident and emergency departments. The risk of infection is increased with puncture wounds, hand injuries, full-thickness wounds, wounds requiring debridement, and those involving joints, tendons, ligaments or fractures. Comorbid medical conditions, such as diabetes, asplenia, chronic edema of the area, liver dysfunction, the presence of a prosthetic valve or joint, and an immunocompromised state may also increase the risk of infection. Other Complications of Bites Infection may spread beyond the initial site, leading to septic arthritis, osteomyelitis, endocarditis, peritonitis, septicemia, and meningitis. If enough force is used, bones may be fractured or the wounds may be permanently disfiguring. Initial Management Assessment regarding whether hospital treatment is necessary should be made as soon as possible. Always refer if the wound is bleeding heavily or fails to stop when pressure is applied. Penetrating bites involving arteries, nerves, muscles, tendons, the hands, or feet, resulting in a moderate to serious facial wound, or crush injuries, also require immediate referral. A full forensic documentation of the bite should be made as detailed in Chapter 4. Note if there are clinical signs of infection, such as erythema, edema, cellulitis, purulent discharge, or regional lymphadenopathy. Wound closure is not generally recom- mended because data suggest that it may increase the risk of infection. This is particularly relevant for nonfacial wounds, deep puncture wounds, bites to the hand, clinically infected wounds, and wounds occurring more than 6–12 hours before presentation. Head and neck wounds in cosmetically important areas may be closed if less than 12 hours old and not obviously infected. Viruses • Dog bites—outside of the United Kingdom, Australia, and New Zealand, rabies should be considered. In the United States, domestic dogs are mostly Infectious Diseases 265 vaccinated against rabies (57), and police dogs have to be vaccinated, so the most common source is from racoons, skunks, and bats. Antibiotic Prophylaxis Antibiotics are not generally needed if the wound is more than 2 days old and there is no sign of infection or in superficial noninfected wounds evalu- ated early that can be left open to heal by secondary intention in compliant people with no significant comorbidity (58). Antibiotics should be considered with high-risk wounds that involve the hands, feet, face, tendons, ligaments, joints, or suspected fractures or for any penetrating bite injury in a person with diabetes, asplenia, or cirrhosis or who is immunosuppressed. Coamoxiclav (amoxycillin and clavulanic acid) is the first-line treatment for mild–moderate dog or human bites resulting in infections managed in pri- mary care. For adults, the recommended dose is 500/125 mg three times daily and for children the recommended does is 40 mg/kg three times daily (based on amoxycillin component). It is also the first-line drug for prophylaxis when the same dose regimen should be prescribed for 5–7 days. If the individual is known or suspected to be aller- gic to penicillin, a tetracycline (e. In the United Kingdom, doxycycline use is restricted to those older than 12 years and in the United States to those older than 8 years old. Anyone with severe infection or who is clinically unwell should be referred to the hospital. Tetanus vaccine should be given if the primary course or last booster was more than 10 years ago. If the person has never been immunized or is unsure of his or her tetanus status, a full three-dose course, spaced at least 1 month apart, should be given. General Information Respiratory tract infections are common, usually mild, and self-limit- ing, although they may require symptomatic treatment with paracetamol or a nonsteroidal antiinflammatory. These include the common cold (80% rhi- noviruses and 20% coronaviruses), adenoviruses, influenza, parainfluenza, and, during the summer and early autumn, enteroviruses. Special attention should be given to detainees with asthma or the who are immunocompromised, because infection in these people may be more serious particularly if the lower respiratory tract is involved. The following section includes respiratory pathogens of special note because they may pose a risk to both the detainee and/or staff who come into close contact. General Information and Epidemiology There are five serogroups of Neisseria meningitidis: A, B, C, W135, and Y. In the United Kingdom, most cases of meningitis are sporadic, with less than 5% occurring as clusters (outbreaks) amongst school children. Between 1996 and 2000, 59% of cases were group B, 36% were group C, and W135 and A accounted for 5%.
