Self-control and stress Recently, theories of stress have emphasized forms of self-control as important in under- standing stress. This is illustrated in theories of self-efficacy, hardiness and feelings of mastery. In 1987, Lazarus and Folkman suggested that self-efficacy was a powerful factor for mediating the stress response. Self-efficacy refers to an individual’s feeling of confidence that they can perform a desired action. Research indicates that self-efficacy may have a role in mediating stress-induced immunosuppression and physiological changes such as blood pressure, heart rate and stress hormones (e. For example, the belief ‘I am confident that I can succeed in this exam’ may result in physiological changes that reduce the stress response. This shift towards emphasizing self-control is also illustrated by Kobasa’s concept of ‘hardiness’ (Kobasa et al. Hardiness was described as reflecting (a) personal feelings of control; (b) a desire to accept challenges; and (c) commitment. It has been argued that the degree of hardiness influences an individual’s appraisal of potential stressors and the resulting stress response. Accordingly, a feeling of being in control may contribute to the process of primary appraisal. Karasek and Theorell (1990) defined the term ‘feelings of mastery’, which reflected an individual’s control over their stress response. In summary, most current stress researchers consider stress the result of a person environment fit and emphasize the role of primary appraisal (‘is the event stressful? This research has highlighted two main groups of physiological changes (see Figure 10. This results in the production of catecholamines (adrenalin and noradrenalin, also known as epinephrine and norepinephrine) which cause changes in factors such as blood pressure, heart rate, sweating and pupil dilation and is experienced as a feeling of arousal. Catecholamines also have an effect on a range of the bodies tissues and can lead to changes in immune function. This results in the production of increased levels of corticosteroids the most important of which is cortisol which results in more diffuse changes such as the management of carbo- hydrate stores and inflammation. These changes constitute the background effect of stress and cannot be detected by the individual. They are similar to the alarm, resistance and exhaustion stages of stress described by Seyle (1956). In addition, raised levels of the brain opiods beta endorphin and enkaphalin have been found following stress which are involved in immune-related problems. The physiological aspects of the stress response are linked to stress reactivity, stress recovery, the allostatic load and stress resistance. Stress reactivity Changes in physiology are known as ‘stress reactivity’ and vary enormously between people. For example, some individuals respond to stressful events with high levels of sweating, raised blood pressure and heart rate whilst others show only a minimal response. This, in part, is due to whether the stressor is appraised as stressful (primary appraisal) and how the individual appraises their own coping resources (secondary appraisal). However, research also shows that some people are simply more reactive to stress than others, regardless of appraisal. Two people may show similar psychological reactions to stress but different physiological reactions. In particular, there is some evidence for gender differences in stress reactivity with men responding more strenu- ously to stressors than women and women showing smaller increases in blood pressure during stressful tasks than men (Stoney et al. Stress reactivity is thought to be dispositional and may either be genetic or a result of prenatal or childhood experiences. However, there is great variability in the rate of recovery both between individuals as some people recover more quickly than others and within the same individual across the lifespan. Allostatic load: Stress recovery is linked with allostatic load which was described by McEwan and Stellar (1993).
Neurological Evaluation of children’s level of consciousness is based largely on alertness abana 60 pills fast delivery cholesterol and saturated fat in shrimp, response to environment and parents abana 60 pills cheap cholesterol reducing diet, level of activity and their cry. Neurological evaluation resembles that of an adult (see Chapter 22), but with infants some reflexes (e. The immature respiratory system differs not only in size and anatomical position but, with growth of the thorax, lung mechanisms are altered. Many anatomical differences affect respiratory care: ■ Infants are obligatory nose breathers, with a longer epiglottis which may need to be lifted by a straight blade during intubation. Endotracheal tubes should allow a small leak while achieving adequate pulmonary inflation pressures. Paediatric artificial airways may quickly become obstructed by mucous, therefore humidification with an appropriate system is vital (Tibballs 1997). Artificial ventilation for children is similar to adults, but with less margin for error (Betit et al. Children below 10 kg are usually ventilated with pressure control cycles; volume cycles are used for larger children. Pressure control ventilation reduces barotrauma in the immature lungs of smaller children and compensates for the airleak from uncuffed tubes. For infants, prone positioning does not interfere with diaphragmatic action (unlike supine positions). Unilateral lung disorders necessitate careful positioning: lying on the affected side helps to ventilate the good lung but decreases perfusion, improving overall oxygenation; positioning the affected lung uppermost helps drainage but impairs expansion, and so oxygenation. During physiotherapy the child is repositioned to assist lung drainage, possibly requiring additional oxygen during treatments (Robb 1995). Endotracheal suctioning of adults and children is similar (see Chapter 5), but there are additional complications with children, requiring special considerations: ■ correct size suction catheters ■ suction pressures 7–13 kPa (50–100 mmHg) ■ preoxygenation to prevent hypoxia ■ during bagging, use of pressure monitors is advisable to prevent barotrauma ■ limit manual inflation pressures to 10 cmH2O above set peak pressures Complications of endotracheal suction can include ■ accidental extubation ■ cilia damage (see Chapter 5) ■ perforation of carina (rare) Intensive care nursing 116 Cardiovascular Cardiac dysrhythmias and arrest are rare in children unless they have congenital abnormalities or are exposed to sustained hypoxia (e. As with adults, persistent hypoxia causes metabolic acidosis and dysrhythmias (especially bradycardia); dysrhythmias reduce cardiac output, provoking cardiac arrest (Hazinski 1992). As with adults, shock not responding to intravascular fluids and adequate oxygenation may require inotropic support. Inotropes are the same as those used for adults (see Chapter 34), but higher doses per kilogram may be needed and combinations of two or more are often used. Children have higher metabolic rates and greater insensible water loss than adults so that daily fluid requirement per kilogram (Table 13. Nurses should therefore consider the child’s fluid balance and clinical condition when calculating children’s fluid requirements. Fluid input includes all infusions, bolus drugs, flushes, transducer flushes and nutrition. Continuous transducer infusions deliver 3 ml/hour for each transducer when the pressure bag is inflated to 300 mmHg. Electrolyte disturbances include hypoglycaemia, hypocalcaemia, hypo/hypernatraemia and hyperkalaemia (Hazinski 1992). As infants require high levels of glucose, drug infusions are ideally mixed in a glucose solution. Normal urine output for children is 2 ml/kg body weight/hour below 2 years and 1 ml/kg/body weight/hour above 2 years. If a catheter or collecting bag is not used, nappies should be weighed to maintain a correct fluid balance (1 g=approximately 1 ml water). Differences of more than 4°C between core and peripheral temperature indicate inadequate perfusion, which may respond to a fluid challenge. Infants and young children may show non-specific signs of infection, although temperature usually rises or falls significantly. Sepsis often causes: ■ a reluctance to feed ■ drowsiness ■ vomiting ■ failure to gain weight ■ greyish pallor and an anxious look (Robb 1995) Hygiene and care Nurses should discuss and plan hygiene care with parents. Despite sedation, children may be aware of their parents’ presence through sensory stimulation (touch, sound, smell).

Penicillin purchase 60pills abana fast delivery test your cholesterol iq, the first antibiotic cheap abana 60pills cholesterol test device, is a bacteriocidal and kills bacteria using lysis, which explodes the bacteria into parts. Today there are many synthetic and semi-synthetic antimicrobials on the mar- ket that stop some bacteria from growing and kill other bacteria. For example, chloramphenicol is bacteriostatic and stops most bacteria from growing while it is bacteriocidal and kills S pneumoniae and H influenza in cerebral spinal fluid. Tetracycline is also bacteriostatic and bacteriocidal; in small concentrations it stops the growth of bacteria and in high concentration it kills bacteria. Sulfonamides and penicillin are administered orally, topically as an ointment or cream, or parenterally and are absorbed into the body and distributed by the circulatory system. In severe infections, they can be administered directly at the site of the infection such as in the eye or rubbed on the skin. The membrane is within the cell wall and is used to let nutrients into the cell and send waste out of the cell. Medications that stop the growth of bacteria interrupt steps in protein syn- thesis. They inhibit the bacteria’s capability to make (synthesize) essential metabolites. A metabolite is a component necessary for bacteria’s metabo- lism to function properly. Medication used to stop the growth of microbials or kill them outright have side effects, some of which can adversely affect the patient. Some cause an aller- gic reaction while others lead to an exaggerated immune response. Here are a few common ones that you probably recognize: • Rash • Fever • Urticaria (hives) with pruritis (itching) • Chills, general erythema (redness) • Anaphylaxis (circulatory collapse) These side effects are usually treatable by using other medication such as: • Antihistamines (Benadryl) • Epinephrine (adrenalin) • Steroids for anti-inflammatory response Superinfections Antibiotics are a good thing—and a not so good thing. This is a greater risk when large doses of anti- biotics are used, when more than one antibiotic is used at a time, or when broad- spectrum drugs are used. For example, the overuse of cephalosporins may cause pseudomonas and the overuse of tetracycline may cause candida albicans. Pseudomonas and candida albicans are then considered to be a superinfection in response to the use of cephalosporins and tetracycline. Culture and sensitivity studies should be performed on all infections in order to determine which antibiotics will work for the microorganism that is causing the infection. The test can be performed on blood or wound drainage to identify the bacteria and help identify which antibiotic will be effective. Other times, the prescriber may underprescribe an antibiotic by giving the patient a lower-than-effective dose or order the antibiotic for a short period of time. At first this seems like a logical way to prevent the bacterium from becom- ing resistant to the antibiotic. However, a low dose may not completely kill the bacterium resulting in a recurrence of symptoms that requires additional doses of antibiotics. It is very important to choose the right antibiotic, in the right dose, for the right amount of time. Preparing to Administer Antimicrobial Medication Antimicrobial medication requires the nurse to follow the same general admin- istration procedures that are required for any type of medication. The most critical step is to determine if the patient has allergies to drugs, food, environ- mental stimuli, and a family history of allergies to antibiotics. There is also a high incidence of cross sensitivity between some antibiotics such as penicillin and cephalasporins. Even if the patient’s record indicates that the patient doesn’t have allergies, always ask the patient each time you administer the antimicrobial medication. Always have emergency medications such as epinephrine, Benadryl, and steroids handy so they can be given to counteract any adverse side effect of the antimicrobial medication. Be sure to carefully monitor the patient for a half hour after the medication is given to determine if the patient experiences an adverse reaction. During treatment, you’ll need to monitor the therapeutic effect of the med- ication by monitoring the signs and symptoms of the disease and by obtaining the patient’s white blood cell count. Although you can monitor the antimicro- bial serum level to determine if the medication has achieved a therapeutic level, this is only done in cases where the therapeutic range is narrow resulting in pos- sible toxicities (i. It is important to administer antimicrobials at the times described in the pre- scriber’s order in order to maintain a therapeutic blood level of the medication. Sometimes a double dose of an antibiotic is administered as the first dose to quickly achieve a therapeutic level.
