Belize Telemedia Limited has successfully increased its wireless coverage nationwide, covering most of the rural communities in Belize by deploying Nortel wireless technology (Cronin 29, 2007). This technology has completely replaced the old Belize Telemedia existing GSM structure given by Nortel competitor; as well deploy a new CDMA 450 MHz network to hold up Telemedia’s emergent subscriber demand in Belize and the requirement for more superior, high-tech products and facilities countrywide. .Telemedia’s existing wireless setup has been improved and enhanced to Nortel GSM GPRS/EDGE 850/1900 MHz wireless network which offers superior network coverage and connectivity for the consumers. In addition, the operator has launched a completely new network laid on Nortel CDMA xRTT and 1xEV-DO technologies in the 450 MHz range, to expand services and assist to seal the means of communication space in rural society (Cronin 29, 2007). According to Dean Boyce who is the chairperson of the executive committee at Belize Telemedia, the Nortel technologies has successfully enhanced the reputation of Belize Telemedia and also given wide-ranging services which has strengthen Telemedia’s network.

The Belize government welcomed the 2004 sale of the nationwide telephone corporate to a U.S-Caribbean organization as a moment of guarantee and affiliation. The main highlight was the $90 million deal (Fox 103, 2007). However, the agreement was tattered and became a story of officially permitted and oral clash. The clash started when Musa management took full authority of Belize Telecommunication Ltd from Prosser and his company after the failure to pay $57 million to the government for the phone company. Prosser filed a case in which he demanded the court to give out a command that would invalidate the boardroom occupation and put him back in charge. Prosser’s attorney was Lanny Davis who criticized the Belize government by calling it lawless after the assembly approved a law allowing the occupation of specified telephone company shares after Prosser’s non-payment. In the initial stages of the case, U. S District Judge Ursula Ungaro-Benages instructed Belize to invalidate its conflict against ICC, and then hit the government with a disrespect, scorn allegation for refusal to comply, signifying that Belize authorities gave the impression to want to be hit over the head by a 2-by-4. UngaroBenages passed the verdict which favored the Belize government. The liberalization of the telecommunication market at various phases, from Guatemala to Costa Rica remains government owned. Costa Rica’s fixed-line tele-density is the highest in South America while that in Guatemala is 40 percent less than the complete South American average, which shows that fixed line privatization and competition are no assurance of the development there. The study reveals that low fixed line tele-density causes leapfrogged unswervingly into mobile communications. Mobile competition is intense and diffusion is far away that would be anticipated bearing in mind their other macroeconomic pointers (Fox 103, 2007). Belize is the only exemption since it has national owned mobile company. Broadband services also vary greatly among these seven countries. Efforts are being made to liberalize Belize’s telecommunication market. Belize stands out from its neighboring countries as a financial leader, having already commenced the internet trend that would hit its neighbors in the entire South American Region. The interests of foreign companies to chase the liberalization of the Belize telecommunication market set up in the country and use that country as a launch pad to launch its rising information technology business throughout the area. The initiation of foreign competitors in the Belize telecommunication market needs a legitimate alteration and adjustment to suspend the current government utility company’s domination in the market.

Nursing Study Guide Block 4 Final

Study Guide for the Final Exam Here are the rules: please do not call me or email me questions about the study guide. I will answer questions about the study guide during the brief review before the exam itself. You cannot memorize the answers to the questions and do well on the exam- the questions are meant to stimulate thinking, not to be answers. Please remember to review the chapters on shock and MODS as there are questions on this content. 1.There are several ABG questions; remember these also include oxygen numbers so be prepared to determine oxygenation in addition to acid base PH: 7. 35- 7. 45 PCO2: 35-45 HCO3: 22-26 O2: 94-100 2.

Demonstrates effective RR, rhythm, and depth of respirations. Reports control of pain following relief measures. . Review the treatment for TB (look in Lewis), including medications, length of treatment, evaluation of treatment plan, who is most likely to get TB infection, and side effects of the medications Medications: aggressive TB treatment: four drugs for 6 months, (INH, rifampin [Rifadin], pyrazinamide [PZA], and ethambutol) Newer: rifamycins, rifubin, rifapentine, first line for special situations Length of treatment: 6 months- 1 YearEvaluation of treatment plan: resolution of the disease, normal pulmonary function, absence of any complication, no transmission of TB, Most likely to contract: Asians have the highest TB rate, followed by Hawaiians and pacific islanders. African Americans are the highest rate inside the US. (45%) Higher rates of TB infections with patients with HIV infections Side effects of meds: alcohol increases hepatotoxicity of INH, monitor liver function.PZA may not be included in initial phase (due to liver disease or pregnancy) 4. Review the care of a patient with lung surgery, including chest tube management To keep lung inflated & Drain fluid from interpleural space How do you know if collapsed lung: Blood gases, Chest X-ray, Vital signs, Color Air leaks – bubbling in water chamber: check your tubes for air leak & make sure they’re always free of kinks. Don’t milk the chest tube (unless ordered).Continued bubbling = pneumothorax not resolved yet, Constant vigorous bubbling = air leak in system Should see tidaling if not attached to suction >100cc/hr. of drainage = call doc Determine if working correctly by: Monitor output, pain, breath sounds, assess patient breathing, auscultate, ABG, pulse ox (SPO2), skin/mucous membrane coloring, and respiratory effort Chest tube pain is common- give pain meds >7/10 5.Review heart failure: right-sided (acute and chronic), left- sided (acute and chronic), pulmonary edema, cardiomyopathy and management of the patients; remember to review the hemodynamic changes (and values) associated with right and left sided failure RIGHT SIDED HF: (FLUID RETENTION): Corpulmonale, systemic edema, neck vein distention, weight gain, fluid retention, Risk: COPD, hypoxia (pulmonary HTN), causes pulmonary vasoconstriction.CVP = increased; PVR = increased; SVR = increased; wedge = increased; contractility = decreased medication: nitroglycerine to decrease venous return, fix preload LEFT SIDED HF: (RESPIRATORY) DYSPNEA ON EXERTION, back up in lungs, pink frothy sputum, decreased O2 stat, increase RR. CVP = increased; PVR = incre ased; SVR = increased; wedge = increased; contractility = decreased HEART FAILURE: Usually starts out with one ventricle.Nitroglycerine, aspirin, O2, pericardial thump, Lasix, ACE, + inotrope, Class 4, transplant, symptomatic. ACUTE HF: Dig, Lasix, ACE, ARBS, Betas, Calcium Channel, Nitro, and Aspirin, compensatory mechanism is ok. CHRONIC HF: both ventricles can fail (left to right), Dig, Lasix, ACE, BETA, ARBS (if cough), calcium channel blocker, Primacore, compensatory mechanism makes it worse. 2 CLASSIFICATIONS OF HF: 1. Systolic: problems pushing volume out problem with too much afterload: HTN. TX: decrease SVR with dig, Lasix (diuretics), ACE. 2.Diastolic: problem with filling and getting blood in (Hypertrophic cardio) less room for blood TX: Beta blockers to reduce contraction or calcium channel then ACE. If you give them DIG it will kill them (will increase heart working too hard). PULMONARY EDEMA: hallmark: pink frothy sputum, Left- sided heart failure. Decreased albumin, d ecreased oncotic pressure, increased hydrostatic pressure. Dilated: Left vent is dilated (stretched out of shape) decreasing the ejection fraction. Vent is overstretched from CHF or chronic hypertension.Diagnose with chest X-ray: heart is BIG. TX: Dig, Lasix, Ace. Arrhythmias will increase mortality rate HYPERTROPHIC: L vent hypertrophy decreases the ability of the chamber to relax, decrease contractility (athlete, hereditary. ) TX: BB, CCB Constricted/restricted: normal size heart with decreased cardiac muscle compliance. Scarred= fibrosis, radiation, infection (rheumatic fever) control of volume overload is AGGRESSIVE: Ace, Diuretic, Dobutamine, Nitroglycerin/Nitropresside, exercise restriction .

The Haunting Truth Behind The Lake by Edgar Allan Poe

Poe first published â€Å"The Lake† in his 1827 collection Tamerlane and Other Poems, but it appeared again two years later in the collection Al Aaraaf, Tamerlane, and Minor Poems with a mysterious dedication added to the title: â€Å"The Lake. To–.† The subject of Poes dedication remains unidentified to this day. Historians have suggested  Poe wrote the poem about Lake Drummond—and that he might have visited Lake Drummond with his foster mother, but the poem was published after her death. The lake outside Norfolk, Virginia, also known as the Great Dismal Swamp, was said to have been haunted by two past lovers. The supposed ghosts were not thought of as malicious or evil, but tragic—the boy had gone mad in the belief the girl had died. A Haunted Lake Lake Drummond was said to be haunted by the spirits of a young Native American couple who lost their lives on the lake. The young woman reportedly died on their wedding day, and the young man, driven mad by visions of her paddling on the lake, drowned in his attempts to reach her. According to one report, local legend says that if you go into the Great Dismal Swamp late at night youll see the image of a woman paddling a white canoe on a lake with a lamp. This woman became known locally as the Lady of the Lake, which has given inspiration to a slew of famous writers over the years. Robert Frost was said to have visited the central Lake Drummond in 1894 after suffering a heartbreak from splitting up with a longtime lover, and he later told a biographer that he had hoped to get lost in the wilderness of the swamp, never to return. Although the haunting stories may be fictional, the beautiful scenery and lush wildlife of this Virginia lake and surrounding swamp draw many visitors every year. Poes Use of Contrast One of the things that stands out in the poem is the way Poe contrasts the dark imagery and danger of the lake with a feeling of contentment and even pleasure in the thrill of his surroundings. He refers to the loneliness as lovely, and later describes his delight at waking to the terror on the lone lake. Poe draws on the legend of the lake to tap into its inherent dangers, but at the same time he revels in the beauty of the nature surrounding him. The poem closes with Poes exploration of the circle of life. Though he refers to death in a poisonous wave, he describes its location as Eden, an obvious symbol for the emergence of life. Full Text of The Lake. To In spring of youth, it was my lotTo haunt of the wide world a spotThe which I could not love the less–So lovely was the lonelinessOf a wild lake, with black rock bound,And the tall pines that towered around.But when the Night had thrown her pallUpon that spot, as upon all,And the mystic wind went byMurmuring in melody–Then–ah then I would awakeTo the terror of the lone lake.Yet that terror was not fright,But a tremulous delight–A feeling not the jewelled mineCould teach or bribe me to define–Nor Love—although the Love were thine.Death was in that poisonous wave,And in its gulf a fitting graveFor him who thence could solace bringTo his lone imagining–Whose solitary soul could makeAn Eden of that dim lake.
