Recognize common skin eruptions and manifestations associated with systemic disease. Describe the normal aging process of the skin and skin changes common to elderly patients. List appropriate questions that will help elicit information during an assessment of the skin. Describe the components of physical assessment most useful when examining the skin, hair, and nails. Discuss common skin tests and procedures used in diagnosing skin and related disorders. Skin-related disorders account for up to 10% of all ambulatory patient visits in this country. Because the skin mirrors the general condition of the patient, many systemic conditions may be accompanied by dermatologic manifestations (Fleischer et al. The psychological stress of illness or various personal and family problems is commonly exhibited outwardly as dermatologic problems. Any hospitalized patient may suddenly develop itching and a rash from the treatment regimen. In certain systemic conditions, such as hepatitis and some cancers, dermatologic manifestations may be the first sign of the disorder. S Chapter 55 Assessment of Integumentary Function 1639 Anatomic and Physiologic Overview the largest organ system of the body, the skin is indispensable for human life. Skin forms a barrier between the internal organs and the external environment and participates in many vital body functions. The skin is contiguous with the mucous membrane at the external openings of the digestive, respiratory, and urogenital systems. Because skin disorders are readily visible, dermatologic complaints are commonly the primary reason for a patient to seek health care. The epidermis is an outermost layer of stratified epithelial cells and composed predominantly of keratinocytes. Four distinct layers compose the epidermis, from innermost to outermost: stratum germinativum, stratum granulosum, stratum lucidum, and stratum corneum. Each layer becomes more differentiated (ie, mature and with more specific functions) as it rises from the basal stratum germinativum layer to the outermost stratum corneum layer. Epidermis the epidermis, which is contiguous with the mucous membranes and the lining of the ear canals, consists of live, continuously dividing cells covered on the surface by dead cells that were origi- nally deeper in the dermis but were pushed upward by the newly developing, more differentiated cells underneath. The dead cells contain large amounts of keratin, an insoluble, fibrous protein that forms the outer barrier of the skin and has the capacity to repel pathogens and prevent excessive fluid loss from the body. Melanocytes are the special cells of the epidermis that are primarily involved in producing the pigment melanin, which colors the skin and hair.

Aspiration of gastric contents or feedings may occur antimicrobial peptides discount azithromycin online amex, precipitating the development of pneumonia or airway occlusion antibiotics used to treat pneumonia cheap azithromycin 500 mg. The patient may be orally or nasally intubated anti virus azithromycin 100mg without a prescription, or a tracheostomy may be performed antibiotic infusion therapy order azithromycin on line. The circulatory status (blood pressure, heart rate) is monitored to ensure adequate perfusion to the body and brain. An intravenous catheter is inserted to provide access for fluids and intravenous medications. Nutritional support, using either a feeding tube or a gastrostomy tube, is initiated as soon as possible. Initial changes may be reflected by subtle behavioral changes such as restlessness or increased anxiety. The pupils, normally round and quickly reactive to light, become sluggish (response is slower); as the patient becomes comatose, the pupils become fixed (no response to light). The patient in a coma does not open the eyes, respond verbally, or move the extremities in response to a request to do so. A complete assessment is performed, with particular attention to the neurologic system. It includes an evaluation of mental status, cranial nerve function, cerebellar function (balance and coordination), reflexes, and motor and sensory function. A score of 3 indicates severe impairment of neurologic function; a score of 15 indicates that the patient is fully responsive (see Chap. The patient is asked to identify the day, date, or season of the year and to identify where he or she is or to identify the clinicians, family members, or visitors present. The nurse should assess for periorbital edema or trauma, which may prevent the patient from opening the eyes, and document if this interferes with eye opening. Motor response includes spontaneous, purposeful movement (eg, the awake patient can move all four extremities with equal strength), movement only in response to noxious stimuli (eg, pressure/pain), or abnormal posturing (Bateman, 2001). If the patient is not responding to commands, the motor response is tested by applying a painful stimulus (firm but gentle pressure) to the nailbed or by squeezing a muscle. If the patient attempts to push away or withdraw, the response is recorded as purposeful or appropriate ("patient withdraws to painful stimuli"). This response is considered purposeful if the patient can cross from one side of the body to the other in response to noxious stimuli. Occasionally, posturing cannot be elicited if the patient has been given pharmacologic paralyzing agents. Table 61-1 summarizes the assessment and the clinical significance of the findings. Body functions (circulation, respiration, elimination, fluid and electrolyte balance) are examined in a systematic and ongoing manner. Additional goals include bowel continence, accurate perception of environmental stimuli, maintenance of intact family or support system, and absence of complications (Jacobson & Winslow, 2000). The nurse must assume responsibility for the patient until the basic reflexes (coughing, blinking, and swallowing) return and the patient becomes conscious and oriented. Thus, the major nursing goal is to compensate for the absence of these protective reflexes. Disturbances of respiratory center of brain may result in various respiratory patterns. Functional and structural integrity of brain stem is assessed by inspection of extraocular movements; usually absent in deep coma. Asymmetric response in paralysis Absent in deep coma Flexion of the toes, especially the great toe, is normal except in newborn. Dorsiflexion of toes (especially great toe) indicates contralateral pathology of corticospinal tract (Babinski reflex). Helps determine location of lesion in brain Abnormal posture Observation for posturing (spontaneous or in response to noxious stimuli) Flaccidity with absence of motor response Decorticate posture (flexion and internal rotation of forearms and hands) Decerebrate posture (extension and external rotation) Deep extensive brain lesion Seen with cerebral hemisphere pathology and in metabolic depression of brain function Decerebrate posturing indicates deeper and more severe dysfunction than does decorticate posturing; implies brain pathology; poor prognostic sign. Obstruction of the airway is a risk because the epiglottis and tongue may relax, occluding the oropharynx, or the patient may aspirate vomitus or nasopharyngeal secretions. Because the patient cannot swallow and lacks pharyngeal reflexes, these secretions must be removed to eliminate the danger of aspiration. Positioning the patient in a lateral or semiprone position will also help as it permits the jaw and tongue to fall forward, thus promoting drainage of secretions.

Chemical or biological agents and radiation are silent killers and are generally colorless and odorless infection 5 weeks after surgery order azithromycin 100 mg fast delivery. Use of biological weapons dates far back into history antibiotic ear drops discount azithromycin 100 mg without a prescription, but improved production techniques and genetic engineering have expanded the potential for widespread casualties as a result of biological weaponry super 8 bacteria purchase 250mg azithromycin fast delivery. Overall antibiotics headache purchase azithromycin 500 mg line, biological weapons are easily obtained and easily disseminated, and they result in significant mortality and morbidity. The potential use of biological agents calls for continuous increased surveillance by health departments and an increased index of suspicion by clinicians. Many biological weapons result in signs and symptoms similar to those of common disease processes. Biological agents are delivered in either a liquid or dry state, applied to foods or water, or vaporized for inhalation or direct contact. Vaporization may be accomplished through spray or explosives loaded with the agent. With increased travel, an agent could be released in one city and affect people in other cities thousands of miles away. The vector can be an insect, animal, or person, or there may be direct contact with the agent itself. The following is a discussion of two of the agents most likely to be used or weaponized. The bacterium sporulates (is liberated) when exposed to air and is infective only in the spore form. Contact with infected animal products (raw meat) or inhalation of the spores results in infection. Cattle and other herbivores are vaccinated against anthrax to prevent transmission through contaminated meat. It is believed that approximately 8000 to 50,000 spores must be inhaled to put a person at risk. As an aerosol, anthrax is odorless and invisible and can travel a great distance before disseminating; hence, the site of release and the site of infection can be miles apart. In 1979, Sverdlosk, Russia, experienced the intentional release of anthrax, with widespread mortality and morbidity. Anthrax was released with the sarin gas attack in Tokyo, Japan, in 1995; however, the method of release chosen was poorly designed for effect. Anthrax is caused by replicating bacteria that release toxin resulting in hemorrhage, edema, and necrosis. There are three primary methods of infection: skin contact, inhalation, and gastrointestinal ingestion. Skin lesions (the most common infection) cause edema with pruritis and macule or papule formation resulting in ulceration with 1- to 3-mm vesicles. Ingestion of anthrax results in fever, nausea and vomiting, abdominal pain, bloody diarrhea, and occasionally ascites. If massive diarrhea develops, decreased intravascular volume becomes the primary treatment concern. Its symptoms mimic those of the flu, and usually treatment is sought only when the second stage of severe respiratory distress occurs. The inhalation form can have an incubation period of up to 60 days, making it difficult to identify the source of the bacterium. Initial signs and symptoms include cough, headache, fever, vomiting, chills, weakness, mild chest discomfort, dyspnea, and syncope, without rhinorrhea or nasal congestion. Most patients have a brief recovery period followed by the second stage within 1 to 3 days, characterized by fever, severe respiratory distress, stridor, hypoxia, cyanosis, diaphoresis, hypotension, and shock. These patients require optimization of oxygenation, correction of electrolyte imbalances, and ventilatory and hemodynamic support. More than 50% of these patients have hemorrhagic mediastinitis on chest x-ray (a hallmark sign) (Spencer, Whitman, & Morton 2001; Altman, 2002; Inglesby et al. Death results in approximately 24 to 36 hours after the onset of severe respiratory distress.

A late complication is adenocarcinoma of the sigmoid colon infection questions on nclex purchase generic azithromycin, possibly from cellular changes due to exposure of the colonic mucosa to urine antibiotic vitamin order azithromycin online pills. Urinary carcinogens promote late malignant transformation of the colon after a ureterosigmoidostomy antibiotics for steroid acne azithromycin 500mg. Therefore treatment for uti in hospital azithromycin 500mg low price, diligent patient teaching regarding the need for life-long medical followup is essential (Guy et al, 2001; Huang & McPherson, 2000). These techniques involve isolating a part of the large intestine to form a reservoir for urine and creating an abdominal stoma. Another surgical procedure, the Camey procedure, uses a portion of the ileum as a bladder substitute. In this procedure, the isolated ileum serves as the reservoir for urine; it is anastomosed directly to the portion of the remaining urethra after cystectomy. The Camey procedure, however, applies only to men because the entire urethra is removed when a cystectomy is performed in women. Nursing Management In addition to the usual preoperative regimen, the patient may be placed on a liquid diet for several days preoperatively to reduce residue in the colon. Ureterosigmoidostomy requires a competent anal sphincter, adequate renal function, and active renal peristalsis. The postoperative regimen initially includes placing a catheter in the rectum to drain the urine and prevent reflux of urine into the ureters and kidneys. The tube is taped to the buttocks, and special skin care is given around the anus to prevent excoriation. Irrigations of the rectal tube may be prescribed, but force is never used because of the danger of introducing bacteria into the newly implanted ureters. Fluid and electrolyte balance is maintained in the immediate postoperative period by closely monitoring the serum electrolyte levels and administering appropriate intravenous infusions. Acidosis may be prevented by placing the patient on a low-chloride diet supplemented with sodium potassium citrate. The patient should be instructed never to wait longer than 2 to 3 hours before emptying urine from the intestine. This keeps rectal pressure low and minimizes the absorption of urinary constituents from the colon. With reassurance and encouragement and the passage of time, the patient gains greater control and learns to differentiate between the need to void and the need to defecate. Other ways to avoid gas are to avoid chewing gum, smoking, and any other activity that involves swallowing air. Potassium intake is increased through foods and medication because potassium may be lost in acidosis. A nutritional status assessment is important because of possible poor nutritional intake related to underlying health problems. Exhibits normal skin turgor, moist mucous membranes, adequate urine output, and absence of excessive thirst 3. Discusses expected immediate postoperative environment (tubes, machines, nursing surveillance). The patient faces problems in adapting to an external appliance, a stoma, a surgical incision, and altered toileting habits. A visitor from the Ostomy Visitation Program of the American Cancer Society can provide emotional support and make adaptation easier both before and after surgery. Because the patient undergoing a urinary diversion procedure for cancer may be severely malnourished due to the tumor, radiation enteritis, and anorexia, enteral or parenteral nutrition may be prescribed to promote healing. Adequate preoperative hydration is imperative to ensure urine flow during surgery and to prevent hypovolemia during the prolonged surgical procedure. Explanations of the surgical procedure, the appearance of the stoma, the rationale for preoperative bowel preparation, the reasons for wearing a collection device, and the anticipated effects of the surgery on sexual functioning are part of patient teaching. The placement of the stoma site is planned preoperatively with the patient standing, sitting, or lying down to locate the stoma away from bony prominences, skin creases, and fat folds.
