Sommer ot so long ago, it seemed fying the chemical scaffolds of already a record low of one new antibiotic like the fight against infec approved classes of antibiotics. Conse years from 1983 to 1987 (see the figure penicillin in 1929 gave clinicians their quently, drugs that were previously on page 44). Cer and we won’t have the antibiotics we lowed, medical researchers discovered tain bacteria, including strains of Esch need to save lives. Surgeon even carbapenems, which have long inevitably develop resistance to even General William Stewart announced in been the drug of last resort to treat af the most promising new compounds. In effect, for some diseases we are of genes—collectively known as the these life-saving medicines. Although most studies on drug to the 1960s), the spread of antibiotic adds $35 billion in health care costs resistance have focused on disease resistance was balanced by the con and 8 million hospital days per year causing pathogens, recent efforts by tinued discovery and deployment of in the United States. But starting resistant Salmonella outbreak due to colleagues have shifted attention to the in the 1970s, a dwindling interest and contaminated chicken meat was linked resistomes of nonpathogenic bacteria. At least 23,000 Americans abled us to explore the genomes of new broad-spectrum classes of anti die each year from infections, many both pathogenic and non-pathogenic biotics were brought to the market. Sommer is a professor of systems biology and member of the Novo Nord a direct impact on the drug develop isk Foundation Center for Biosustainability at the ment pipeline. During the golden age of discovery, 150 types of lation of genetic changes during the antibiotics were developed. Since then, the spread of resistance has greatly outpaced the rate natural process of copying its genome, of drug development. The Infectious Disease Society of America estimates that 70 percent of and horizontally, by swapping resis hospital-acquired infections in the United States are now resistant to one or more antibiotics. Understanding factors Vertical transmission is the fun how it gets passed between different that influence resistome evolution and damental evolutionary process by bacteria and between different envi dissemination may both extend the life which a cell can accumulate errors in ronments. We are still a long way from of current drugs and point toward new its genome during replication, such Stewart’s old proclamation of victory, disease-fighting strategies. In horizon bacterial transduction tal transmission, resistant genes are swapped from one microbe to another. This can occur via three mechanisms: transforma tion, when bacteria scavenge resistance genes from dead bac release of phage terial cells and integrate them into their own genomes; trans bacterial conjugation duction, when resistance genes are transferred by bacteriophag es (viruses that infect bacteria); or conjugation, when genes are transferred between bacterial cells through tubes called pilli. Four mechanisms of resistance: impermeable barrier (a) blocks antibiotics (blue spheres) a b because the bacterial cell membrane is now modi ed impermeable to the drug. Target modifica drug tion (b) alters the proteins inhibited by the target antibiotic, so the drug cannot bind properly. Antibiotic modification (c) produces an en modi ed zyme that inactivates the antibiotic. Efflux cell wall (d) employs genes coding for enzymes that protein actively pump the antibiotic out of the cell. Not all of these mu tations are advantageous, but about plasmid with antibiotic resistant genes one in a billion will generate mutants that can grow faster or tolerate higher concentrations of antibiotics than their predecessors. When such bacterial mu tants are exposed to antibiotics, those possessing antibiotic resistance genes efflux will increase in prevalence to the point pump of taking over the entire population.

Epidemiology of group A streptococcal upper respiratory tract infection Group A streptococcal infection is endemic throughout the world, but sporadic epidemics are common, particularly among schoolchildren, in residential facilities for the elderly, and in other unique populations such as military personnel. It is thought that natural immunity can be conferred by the surface M-protein of specific group A strep tococci (M-types), but since more than 130 different M-proteins have been described, it is common for individuals throughout their lifetime to have multiple infections by different M-type streptococci. Diagnosis of group A streptococcal pharyngitis To treat patients effectively and prevent suppurative and non suppurative sequelae, it is important that group A streptococcal phar yngitis be diagnosed promptly and accurately. An accurate and prompt diagnosis will not only help to control the spread of infection, it will also minimize the inappropriate use of antibiotics. The inappro priate use of antibiotics is a consideration because most cases of pharyngitis are caused by viruses, and of the many bacterial patho gens that cause pharyngitis (Table 10. Indeed, cases of group A streptococcal pharingytis represent only 20% of all pharyngitis cases (9). The complex of symptoms include a sudden onset of high fever, very sore throat with dysphagia, a scarlatiniform rash and abdominal pain. Numerous at tempts have been made to devise algorithms to make the clinical diagnosis easier (especially in areas where a microbiology laboratory is not available), but in general these algorithms lack accuracy and are not universally helpful. Examples of the most frequently observed clinical findings, signs and symptoms are shown for different age groups in Table 10. No single element of history taking or physical examination is accu rate enough to exclude or diagnose streptococcal throat infection. Patient factors such as age younger than 15 years, history of fever, tonsillar swelling or exudate, tender anterior cervical lymphadenopa thy and absence of cough should all be taken into consideration in arriving at a diagnosis. If four or five of the factors are present, the likelihood ratio of streptococcal infection is 4. Laboratory diagnosis Since the clinical diagnosis of acute streptococcal pharyngitis is often imprecise, laboratory confirmation is needed, although in many parts of the world clinical laboratory facilities are not available (7, 8, 11, 12). If carried out properly, the sensitivity and specificity of this assay 83 Table 10. Rapid antigen detection tests are available in some parts of the world, and almost exclusively use antibodies directed against the group A carbo hydrate of the streptococcal cell wall. In general, they are more expensive than blood agar plates, and like culture plates they need refrigeration, which can be a problem in some parts of the world, especially those with tropical climates. If laboratory facilities are not available, a diagnosis of strepto coccal pharyngitis has to be made on the basis of clinical findings (7, 8, 11–13).

American Indians and Alaska natives have markedly higher rates of 53 pain symptoms compared to U hypertension with hypokalemia buy labetalol 100 mg on-line. Despite this blood pressure emergency level cheap labetalol 100 mg fast delivery, American Indians report minimizing pain complaints and not readily asking for help hypertension risk factors labetalol 100mg discount, likely 54 exacerbating disparities through underdiagnosis and undertreatment. However, the variety of national origins, cultures, languages and ethnicities lead to variations within this group. Lower reports may be due to a general reluctance to report pain (perceived as a sign of weakness) and a fear of side effects of pain medication combined with the potential liability of lower English proficiency 1 and the experience of cultural bias by health professionals. In every ethnic/racial category, women are more likely than men to report a wide range of 1,55,56 chronic pain conditions while pain prevalence varies for women by age and 57 race/ethnicity. Women experience disparities in pain care with misdiagnoses, delays in correct diagnoses, improper and uneven treatment, gender bias, stigma and neglect, and dismissal and 1,58 discrimination from the health care system. Women report greater severity, longer-lasting and more frequent pain than men, and also experience multiple pain problems. Women are 59,60 prescribed opioids and benzodiazepine sedatives at higher rates than men. While men are more likely than women to die from prescription opioid painkillers, the percentage increase in 61 deaths since 1999 is over fivefold greater among women. For every woman who died of an overdose, there were 30 who went to the emergency department for painkiller misuse 61 or abuse. While both boys and girls are more at risk of chronic pain as they get older, girls 14,63 report chronic pain more often than boys. Many pain medicines have not undergone clinical trials or been approved for pediatric use and consequently providers are more reluctant to administer them. The prevalence of chronic pain among independent living older adults ranges from 18 % to 57%, depending on the definition of chronic pain. Additionally, there may be difficulty assessing pain in older adults with cognitive impairment. Side effects of drug treatment may further adversely affect 66-68 their cognitive function and overall health. White, middle-class people in non-urban settings are disproportionately affected by the current opioid crisis. Between 2007-2014, opioid 23 dependence rose by 3,203% among patients privately insured in these communities. Effective 13 pain care is not assured by economic access to care, for example, through private insurers. One could argue that given the risks of standard care, failing to educate patients and recommend nonpharmacologic care should be considered unethical. Complexity of pain categorization There is tremendous variability in the categorization of pain states that can obscure the magnitude of the problem of pain management. Pain is commonly categorized into acute and chronic, according to timeline and connection to tissue injury. Acute pain typically lasts less than 3 months but may persist longer and usually has a clear connection to a physically identifiable 78 nociceptive (pain generating) pathology or tissue damage. Chronic pain is present for longer than 3 months and may or may not have a clear and current connection to an identifiable tissue-based cause, structural injury or defect. Cancer pain can be acute, whether it is post-surgical or due to ongoing nociception, or can be chronic. The timeline of a pain condition is increasingly being recognized as an artificial metric, as the distinguishing features of the mechanisms of acute and chronic pain are recognized.

Bath (Bathing and Skin Care) It is a bath or wash given to a patient in the bed who is unable to care for himself/herself. Cleansing bath: Is given chiefly for cleansing or hygiene purposes and includes: • Complete bed bath: the nurse washes the entire body of a dependent patient in bed • Self-help bed bath: clients confined to bed are able to bath themselves with help from the nurse for washing the back and perhaps the face • Partial bath (abbreviated bath): only the parts of the client’s body that might cause discomfort or odor, if neglected are washed the face, hands, axilla, perineum and back (the nurse can assist by washing the back) omitted are the arms, chest, and abdomen. Also used for therapeutic baths • Shower: many ambulatory clients are able to use shower • the water should feel comfortably warm for the client • People vary in their sensitivity to heat generally it o o should be 43-46 c (110-115 f) • the water for a bed bath should be changed at least once Before bathing a patient, determine a. The bed linen required Note: when bathing a client with infection, the caregiver should wear gloves in the presence of body fluids or open lesion. Principles • Close doors and windows: air current increases loss of heat from the body by convection • Provide privacy – hygiene is a personal matter & the patient will be more comfortable • the client will be more comfortable after voiding and voiding before cleansing the perineum is advisable • Place the bed in the high position: avoids undue strain on the nurses back • Assist the client to move near you – facilitates access which avoids undue reaching and straining • Make a bath mitt with the washcloth. It retains water and heat better than a cloth loosely held • Clean the eye from the inner canthus to the outer using separate corners of the wash cloth – prevents transmitting micro organisms, prevents secretions from entering the nasolacrmal duct • Firm strokes from distal to proximal parts of the extremities increases venous blood return 127 Basic Clinical Nursing Skills Purpose: o To remove transient moist, body secretions and excretions, and dead skin cell o To stimulate circulation o To produce a sense of well being o To promote relaxation, comfort and cleanliness o To prevent or eliminate unpleasant body odors o To give an opportunity for the nurse to assess ill clients o To prevent pressure sores Two categories of baths given to clients o Cleansing o Therapeutic A. Bed Bath Equipment • Trolley • Bed protecting materials such as rubber sheet and towels • Bath blanket (or use top linen) • Two bath towels • Wash cloth • Clean pajamas or gown • Additional bed linens • Hamper for soiled cloths 128 Basic Clinical Nursing Skills 0 0 • Basin with warm water (43-46 c for adult and 38-40 c for children) • Soap on a soap dish • Hygienic supplies, such as, lotion, powder or deodorants (if required) • Screen • Disposable gloves • Lotion thermometer (if available) Procedures 1. Prepare the patient unit • Close windows and doors, use screen to provide privacy. Make a bath with the washcloth, so it retains water and heat than a cloth loosely held 129 Basic Clinical Nursing Skills 4. Assist the patient with grooming • Apply powder lotion or deodorants (of pt uses) • Help patient to care for hair, mouth and nails. Recomfort the patient • Change linen if soiled • Arrange the bed • Put pt in comfortable position • Remove the screen 130 Basic Clinical Nursing Skills i. Give proper care of materials used for bathing • Document and report pertinent data • Observation of the skin condition • General appearance or reaction of the pt • Type of bath give Report any abnormal findings to the nurse in charge B. Saline: 4 ml (1Tsp) NaCl to 500 ml (1 pt) water • Has a cooling effect • Cleans 131 Basic Clinical Nursing Skills • Decrease skin irritation 2. Potassium permanganate (Kmno4): available in tablets, which are crushed, dissolved in a little water, and added to the bath • Cleans and disinfects • Treats infected skin areas 4. Oatmeal (Aveeino) and cornstarch can also be used Tub Bath Typically, bathtubs are low in height to ease the process of getting in and out of the tub. Equipment • Bath blanket • Bath mat • Bath towel • Soap • Clean gown or pajama 132 Basic Clinical Nursing Skills • Clean bed linen • Bath thermometer if available • Disinfectant for cleansing the tub Procedure Check the bath room temperature, which should be warmer than the normal room temperature. After dressing assist the client back to the room Inform the cleaner to carefully clean the tub after the bath Dispose of the glove and wash your hands Document the procedure, describing any unusual client reactions Back Care (massage): includes the area from the back and shoulder to the lower buttocks Purpose • To relieve muscle tension • To promote physical and mental relaxation • To improve muscle and skin functioning • To relieve insomnia • To relax patient • To provide a relieve from pain • To prevent pressure sores (decubitus) • To enhance circulation Equipment Basin of warm water Washcloth Towel Soap 134 Basic Clinical Nursing Skills Skin care lotion Procedure 1. Massaging the back • Pour small amount of lotion (oil) on your palm and rub your palms together to warm the lotion (oil) before massaging. Petrissape: kneading and making large quick pinches of the skin, tissue, and muscle • Clean the back first • Warm the massage lotion or oil before use by pouring over your hands: cold lotion may startle the client and increase discomfort 1. Effleurage the entire back: has a relaxing sedative effect if slow movement and light pressure are used 2. Petrissape first up the vertebral column and them over the entire back: is stimulating if done quickly with firm p 137 Basic Clinical Nursing Skills • Assess: signs of relaxation and /or decreased pain (relaxed breathing, decreased muscles tension, drowsiness, and peaceful affect) ⇒ Verbalizations of freedom from pain and tension ⇒ Areas or redness, broken skin, bruises, or other sings of skin breakdown Note • the duration of a massage ranges from 5-20 minutes • Remember the location of bony prominence to avoid direct pressure over this areas • Frequent positioning is preferable to back massage as massaging the back could possibly lead to subcutaneous tissue degeneration. Backrub requires special skills as it might cause subcutaneous tissue degeneration; mainly in elderly. Offering and Removing Bed Pan • If the individual is weak or helpless, two peoples are needed to place and remove bed pans • If a person needs the bed pan for a longer time periodically remove and replace the pan to ease pressure and prevent tissue damage • Metal bed pans should be warmed before use by: o Running warm water inside the rim of the pan or over the pan o Covering with cloth 138 Basic Clinical Nursing Skills • Semi-Fowler’s position relieves strain on the client’s back and permits a more normal position for elimination Improper placement of the bedpan can cause skin abrasion to the sacral area and spillage o Place a regular bed pan under the buttocks with the narrow end towards the foot of the bed and the buttocks resting on the smooth, rounded rim o Place a slipper (fracture) pan with the flat, low end under the client’s buttocks o Covering the bed pan after use reduces offensive odors and the clients embarrassment If the client is unable to achieve regular defecation help by attending to: 1.
