The nurse measures the girth of an extremity to monitor increased size due to exercise allergy medicine xanax cheap prednisone 10 mg with amex, edema allergy testing on 6 year old order genuine prednisone on line, or bleeding into the muscle allergy symptoms 1dpo discount 20 mg prednisone fast delivery. It is important that the measurements be taken at the same location on the extremity, and with the extremity in the same position, with the muscle at rest. One complication that the nurse needs to be alert for when assessing the patient is compartment syndrome, which is described in detail later in this unit. This major neurovascular problem is caused by pressure within a muscle compartment that increases to such an extent that microcirculation diminishes, leading to nerve and muscle anoxia and necrosis. Function can be permanently lost if the anoxic situation continues for longer than 6 hours. The Patient With Musculoskeletal Injury Special precautions must be taken when assessing a trauma patient. If there is injury to an extremity, it is important to assess for soft tissue trauma, deformity, and neurovascular status. If the patient has a possible cervical spine injury and is wearing a cervical collar, the collar must not be removed until the absence of spinal cord injury is confirmed on x-ray. When the collar is removed, the cervical spine area is gently assessed for swelling, tenderness, and deformity. The patient is assessed for abdominal pain, tenderness, hematomas, and the presence or absence of femoral pulses. Instead, such findings should be reported immediately to the primary health care provider. Bone x-rays determine bone density, texture, erosion, and changes in bone relationships. X-ray study of the cortex of the bone reveals any widening, narrowing, or signs of irregularity. Joint x-rays reveal fluid, irregularity, spur formation, narrowing, and changes in the joint structure. After being positioned for the study, the patient must remain still while the x-rays are taken. After an arthrogram, the joint is usually rested for 12 hours, and a compression elastic bandage is applied as prescribed. In addition, the nurse provides comfort measures (mild analgesia, ice) as appropriate. The nurse should explain to the patient that it is normal to experience clicking or crackling in the joint for a day or two after the procedure, until the contrast agent or air is absorbed. Nursing Interventions Before the patient undergoes an imaging study, the nurse should assess for conditions that may require special consideration during the study or that may be contraindications to the study (eg, pregnancy; claustrophobia; inability to tolerate required positioning due to age, debility, or disability; metal implants). It is used to identify the location and extent of fractures in areas that are difficult to evaluate (eg, acetabulum). At this point, distribution and concentration of the isotope in the bone are determined. An increased uptake of isotope is seen in primary skeletal disease (osteosarcoma), metastatic bone disease, inflammatory skeletal disease (osteomyelitis), and certain types of fractures. In addition, it is important to encourage the patient to drink plenty of fluids to help distribute and eliminate the isotope. Before the scan, the nurse asks the patient to empty the bladder, because a full bladder interferes with scanning of the pelvic bones. To enhance visualization of anatomic structures, contrast media may be injected intravenously. During the procedure, the patient needs to lie still for 1 to 2 hours and will hear a rhythmic knocking sound. Arthrography Arthrography is useful in identifying acute or chronic tears of the joint capsule or supporting ligaments of the knee, shoulder, ankle, hip, or wrist. A radiopaque substance or air is injected into the joint cavity to outline soft tissue structures and the contour of the joint. The joint is put through its range of motion to distribute the contrast agent while a series of x-rays is obtained. If a tear is present, the contrast agent leaks out of the joint and is evident on the x-ray image. Treatment of tears, defects, and disease processes may be performed through the arthroscope.
Older meters that required removal of blood from the reagent strip are generally obsolete allergy shots yahoo answers order prednisone cheap online. The newer meters that do not require removal of blood from the strip generally are easier to use penicillin allergy treatment gonorrhea order prednisone with american express. However allergy medicine mosquito bites order prednisone paypal, most do not provide a backup method for visually assessing the meter results. Patients not receiving insulin may be instructed to assess their blood glucose levels at least two or three times per week, including a 2-hour postprandial test. For all patients, testing is recommended whenever hypoglycemia or hyperglycemia is suspected. Testing is done at the peak action time of the medication to evaluate the need for dosage adjustments. To evaluate basal insulin and determine bolus insulin doses, testing is performed before meals. To titrate bolus insulin doses, regular or lispro, testing is done 2 hours after meals. Patients with type 2 diabetes are encouraged to test before and 2 hours after the largest meal of the day. Patients who take insulin at bedtime or who are on an insulin infusion pump must also test at 3 a. If a patient is unwilling or cannot afford to test frequently, then once or twice a day may be sufficient if the patient varies the time of day to test (eg, before breakfast one day, before lunch the next day). Patients using intensive insulin therapy regimens may be instructed in the use of algorithms (rules or decision trees) for changing the insulin doses based on patterns of values greater or less than the target range and the amount of carbohydrate to be consumed. When there is almost no effective insulin available, the body starts to break down stored fat for energy. Ketone bodies are byproducts of this fat breakdown, and they accumulate in the blood and urine. Urine testing is the most common method used for self-testing of ketone bodies by patients. A meter that enables testing of blood for ketones is available but not widely used. Most commonly, patients use a urine dipstick (Ketostix or Chemstrip uK) to detect ketonuria. Urine ketone testing should be performed whenever patients with type 1 diabetes have glucosuria or persistently elevated blood glucose levels (more than 240 mg/dL or 13. When blood glucose levels are elevated, glucose molecules attach to hemoglobin in the red blood cell. The longer the amount of glucose in the blood remains above normal, the more glucose binds to the red blood cell and the higher the glycosylated hemoglobin level. This complex (the hemoglobin attached to the glucose) is permanent and lasts for the life of the red blood cell, approximately 120 days. If near-normal blood glucose levels are maintained, with only occasional increases in blood glucose, the overall value will not be greatly elevated. However, if the blood glucose values are consistently high, then the test result will also be elevated. Various tests measure the same thing but have different names, including hemoglobin A1C and hemoglobin A1. The normal values differ slightly from test to test and from laboratory to laboratory and normally range from 4% to 6%. Insulin Therapy and Insulin Preparations Because the body loses the ability to produce insulin in type 1 diabetes, exogenous insulin must be administered for life. In type 2 diabetes, insulin may be necessary on a long-term basis to control glucose levels if diet and oral agents fail. In addition, some patients in whom type 2 diabetes is usually controlled by diet alone or by diet and an oral agent may require insulin temporarily during illness, infection, pregnancy, surgery, or some other stressful event. In many cases, insulin injections are administered two or more times daily to control the blood glucose level. They vary according to three main characteristics: time course of action, species (source), and manufacturer.

During the visit allergy testing in orlando prednisone 5mg visa, the nurse assists the patient and family with wound care and exercises allergy symptoms numbness purchase prednisone 20 mg free shipping. Patients with severe or persistent depression or difficulty adjusting to changes in their social and/or occupational roles are identified and referred to the burn team for possible referral to a psychologist allergy medicine non antihistamine order prednisone 5 mg line, psychiatrist, or vocational counselor. The burn team or home care nurse identifies community resources that may be helpful for the patient and family. Several burn patient support groups and other organizations throughout the United States offer services for burn victims. They provide caring people (often recovered burn victims) who can visit a burn patient in the hospital or home or telephone the patient and family periodically to provide support and counseling about skin care, cosmetics, and problems related to psychosocial adjustment. Such organizations, and many regional burn centers, sponsor group meetings and social functions at which outpatients are welcome. Some also provide school-reentry programs and are active in burn prevention activities. If more information is needed regarding burn prevention, the American Burn Association can help locate the nearest burn center and offer current burn prevention tips (see Chart 57-2). Thus, the patient and family are reminded of the importance of periodic health screening and preventive care (eg, gynecologic examinations, dental care). Seeks and achieves return to role in family, school, and community as a contributing member 3. The outpatient setting is appropriate for the care of minor burns and most moderate burns. However, a number of factors must be considered in determining the appropriate site of care. Initially, looking at and touching the burn wound may be difficult and even frightening to some family members and patients. However, with encouragement and support, most can handle burn wound care with little need for daily professional care. Instructions, both verbal and written, are given to the patient about burn wound care, pain management strategies, the need for adequate nutrition, and the importance of exercise and rest. Instruction is also given about signs and symptoms of infection that should be reported to the physician. The importance of notifying the physician about complications early and of keeping follow-up appointments is emphasized to the patient and family. Gerontologic Considerations Nursing assessment of the elderly burn patient should include particular attention to pulmonary function, response to fluid resuscitation, and signs of mental confusion or disorientation. Nursing care promotes early mobilization, aggressive pulmonary care, and attention to preventing complications. Because of lowered resistance, burn wound sepsis and lethal systemic septicemia are more likely in elderly patients. Rehabilitation must take into account preexisting functional abilities and limitations, such as arthritis and low activity tolerance. Elderly patients commonly lack family members who can provide home care, so social services and community nursing services must be contacted to provide optimal care and supervision after hospital discharge.

If vomiting allergy symptoms gas order cheap prednisone, diarrhea allergy shots nhs buy prednisone 10mg, or fever persists allergy shots to cats buy prednisone 20 mg online, take liquids (eg, 1/2 cup regular cola or orange juice, 1/2 cup broth, 1 cup Gatorade) every 1/2 to 1 hour to prevent dehydration and to provide calories. Report nausea, vomiting, and diarrhea to the physician, because extreme fluid loss may be dangerous. For patients with type 1 diabetes, inability to retain oral fluids, may warrant hospitalization to avoid diabetic ketoacidosis and possibly coma. Although the initial plasma concentration of potassium may be low, normal, or even high, there is a major loss of potassium from body stores and an intracellular to extracellular shift of potassium. Insulin administration, which enhances the movement of potassium from the extracellular fluid into the cells. Frequent (every 2 to 4 hours initially) electrocardiograms and laboratory measurements of potassium are necessary during the first 8 hours of treatment. Potassium replacement is withheld only if hyperkalemia is present or if the patient is not urinating. In addition, fluid replacement enhances the excretion of excessive glucose by the kidneys. After the first few hours, half-normal saline solution is the fluid of choice for continued rehydration, if the blood pressure is stable and the sodium level is not low. Moderate to high rates of infusion (200 to 500 mL per hour) may continue for several more hours. Monitoring fluid volume status involves frequent measurements of vital signs (including monitoring for orthostatic changes in blood pressure and heart rate), lung assessment, and monitoring intake and output. Monitoring for signs of fluid overload is especially important for older patients, those with renal impairment, or those at risk for heart failure. Insulin is usually infused intravenously at a slow, continuous rate (eg, 5 units per hour). Thus, an initial insulin infusion rate of 5 units per hour would equal 25 mL per hour. The insulin is often infused separately from the rehydration solutions to allow frequent changes in the rate and content of rehydration solutions. Insulin must be infused continuously until subcutaneous administration of insulin resumes. Any interruption in adminis- Chapter 41 Assessment and Management of Patients With Diabetes Mellitus 1183 tration may result in the reaccumulation of ketone bodies and worsening acidosis. Even if blood glucose levels are dropping to normal, the insulin drip must not be stopped; rather, the rate or concentration of the dextrose infusion should be increased. The basic biochemical defect is lack of effective insulin (ie, insulin resistance). To maintain osmotic equilibrium, water shifts from the intracellular fluid space to the extracellular fluid space. This condition occurs most often in older people (ages 50 to 70) with no known history of diabetes or with mild type 2 diabetes. Instead, they may tolerate polyuria and polydipsia until neurologic changes or an underlying illness (or family members or others) prompts them to seek treatment. Urine output is monitored to ensure adequate renal function before potassium is administered to prevent hyperkalemia. The electrocardiogram is monitored for dysrhythmias indicating abnormal potassium levels. Vital signs, arterial blood gases, and other clinical findings are recorded on a flow sheet. The mortality rate ranges from 10% to 40%, usually related to an underlying illness. The blood glucose level is usually 600 to 1,200 mg/dL, and the osmolality exceeds 350 mOsm/kg. Mental status changes, focal neurologic deficits, and hallucinations are common secondary to the cerebral dehydration that results from extreme hyperosmolality. The patient is asked to describe symptoms that preceded the diagnosis of diabetes, such as polyuria, polydipsia, polyphagia, skin dryness, blurred vision, weight loss, vaginal itching, and nonhealing ulcers.
