Saudi Arabia Recruitment For Nurses

Do you wish to work abroad?

Philippine Nurses are flocking the regions of Saudi Arabia in pursuit for nursing-related jobs.

The jobs offer handsome salaries and they really put the dollar marks on the applicant's sparkling eyes.

Understanding Lupus

Systemic lupus erythematosus is a chronic inflammatory autoimmune disorder of the connective tissue affecting multiple organs. It is characterized by recurring remissions and exacerbations which predominantly affecting women.

How it happens?

  • Immune dysregulation in the form of autoimmunity 
  • B-cell hyperactivity 
  • Causing body to produce antibodies against its own cell components 
  • Activation of immune response by formed antigen-antibody complexes 
  • Production of antibodies against many different tissue components (RBCs, neutrophils, platelets, lymphocytes) or almost any organ or body tissue 
  • Widespread degeneration of connective tissue 
  • Possible cardiovascular, renal, and neurologic complication 
  • Severe bacterial infections

Understanding Lyme Disease

Lyme disease is a multi-systemic disorder caused by Borrelia burgdorferi, a spirochete transmitted through tick bite. This primarily occurs in areas inhabited by small deer ticks (Ixodes dammini). The disease typically manifests in three stages: early localized stage is characterized by a distinctive red rash accompanied by flulike symptoms; early disseminated stage is characterized by neurologic and cardiac abnormalities; and the late stage is characterized by arthritis, chronic neurologic problems.

How it happens? 
  • Tick injects spirochete-laden saliva into host’s bloodstream 
  • After 3 to 32 days of incubation 
  • Spirochetes outward causing characteristic red macule or papule rash (erythema chronicum migrans) 
  • Spirochetes disseminate to other skin sites or organs through bloodstream or lymph system 
  • Spirochetes may survive for years in joint, or they may trigger inflammatory response in host and die.

Understanding Pulmonary Embolism

Pulmonary embolism is the obstruction of pulmonary arterial bed by dislodged thrombus, heart valve growth, or foreign substance. This is considered as the common pulmonary complication in hospitalized patients, usually fatal with massive embolism.

How does pulmonary embolism happen?

  • Blood clot forms in the deep venous system 
  • Clot dislodges and travels through the systemic venous system, right chambers of the heart, and into the pulmonary circulation 
  • Clot lodges in a branch of the circulatory system 
  • Blood flow distal to obstruction is blocked 
  • Embolus prevents alveoli from producing enough surfactant to maintain alveolar integrity 
  • Alveoli collapse and atelectasis develops 
  • Large clot can cause tissue death.

Understanding Hypovolemic Shock

In hypovolemic shock, there is a reduced intravascular blood volume which causes circulatory dysfunction and inadequate tissue perfusion. This requires early recognition and prompt treatment to improve prognosis.

How does this happen?

  • Internal or external fluid loss 
  • Decreased intravascular fluid volume 
  • Diminished venous return 
  • Reduced preload (filling pressure) 
  • Decreased stroke volume 
  • Lowered cardiac output 
  • Reduced mean arterial blood pressure 
  • Decreased tissue perfusion 
  • Reduced oxygen and nutrient delivery to cells 
  • Multiple-organ-dysfunction syndrome.

Understanding Heart Failure

Heart failure is a syndrome that occurs when heart can’t pump enough blood to meet the body’s metabolic needs. This results in intravascular and interstitial volume overload and poor tissue perfusion. It may be classified according to side of heart affected, either left-sided or right-sided heart failure, or cardiac cycle involved (systolic or diastolic dysfunction).

How does this happen?

LEFT-SIDED HEART FAILURE

  • Ineffective left ventricular contractility 
  • Reduced left ventricular pumping ability 
  • Decreased cardiac output to body 
  • Blood backup into left atrium and lungs 
  • Pulmonary congestion, dsypnea, activity intolerance 
  • Pulmonary edema and right-sided heart failure.

RIGHT-SIDED HEART FAILURE

  • Ineffective right ventricular contractility 
  • Reduced right ventricular pumping ability 
  • Decreased cardiac output to lungs 
  • Blood backup into right atrium and peripheral circulation 
  • Weight gain, peripheral edema, engorgement of kidneys and other organs.

Understanding Hyperthyroidism

Hyperthyroidism is a metabolic imbalance which results from overproduction of thyroid hormones. It is also known as thyrotoxicosis. In Grave’s disease, which is its common form, there is an increase of thyroxine (T4) production that causes an enlargement of the thyroid gland (goiter) and multiple system changes. In thyroid storm, which is the acute and sever exacerbation of thyrotoxicosis (which is a medical emergency), possible life-threatening cardiac, hepatic, or renal consequences occur.

How does this happen?

  • T-cell lymphocytes become sensitized to thyroid antigens and stimulate B-cell lymphocytes to secrete autoantibodies 
  • Thyroid-stimulating antibodies bind and stimulate thyroid-stimulating hormone (TSH) receptors of the thyroid gland 
  • The stimulation increases production of thyroid hormone and cell growth
