Grading System for Essays
  • Task Response
  • Coherence and Cohesion
  • Lexical Resource
  • Grammatical Range and Accuracy

“Task Response”
Means that your essay shows that you understood and covered the topic from all its sides, aspects, etc. Let’s take this topic for example – “Internet: connecting or isolating people?”. Those who chose to write about how Internet connects people – loose marks, those who chose to write about how Internet isolates people – loose marks, those who compare and contrast both sides of the Internet and give arguments for and against – gain marks.

“Coherence and Cohesion”
Means how well you connected the paragraphs and sentences inside each paragraph. You see, all of your paragraphs need to be logically connected. For example, if paragraph 1 explains the advantages of the Internet, and paragraph 2 explains its disadvantages, then paragraph 1 should have last sentence saying something like this: “In spite of Internet being such a help in communication, its drawbacks can not be overlooked”. This sentence creates the connection between 1st and 2nd paragraphs. If it wasn’t there, examiner could think that you jumped from advantages to disadvantages without a reason. The same rule applies to sentences inside the paragraph. Every sentence should lead to the next one.


“Lexical Resource”
Means vocabulary and different types of sentences, simple and complex. You should be able to use words and their synonyms.

“Grammatical Range and Accuracy”
Means spelling and grammar of sentences. You should be able to spell the words correctly, do not forget articles “a” and “the”, punctuations is also important, etc.


WRITING
W – Work with a coach.
Practice is one way to enhance your writing skills. However, it would be ideal if you practice with a teacher or IELTS coach that will correct your output. You can never be prepared to combat the IELTS writing tasks without receiving feedbacks on your writing errors. For those who are in a tight budget and cannot afford to hire an IELTS coach, you can work on your own but be sure to have a good IELTS preparatory manual that will serve as your guide in honing of that writing ability.

R – Read through the instructions and questions carefully.
Aside from the main question, the point of issue often will ask you to address three or four things. Make sure to get these queries and discuss them in your answer.

I – Inspect your watch!
Keep track of your time! Monitor your own progress! Remember you only have one hour to finish both writing tasks. For those who have difficulty hitting the 60-minute mark for tasks 1 and 2, speed is developed by practicing constantly.

T – Think and write it out.
While rehearsing your writing ability, sit and write out tasks 1 and 2. Some people are not actually writing the brilliant ideas they were thinking while reading the question. Thus, a structured format approach should be utilized in this case. Repetitive writing can also be avoided if you practice, practice and practice.

I – Inscribe those words legibly!
Messy writing is not a criterion in marking your written output. However, if the examiner cannot read what you have written, then, you are not getting any mark either. Before taking the examination, my coach kept on reminding me about my writing because the words are too small and she had difficulty reading them. Keep in mind than an unreadable output means no mark at all!

N – No reason to start writing immediately for task 1.
Yes, I told you to keep track of your time. But don’t start writing immediately after looking at the graph or table and understanding what is asked and given. Before writing, make sure that you know what each axis represents and the units that are used. Even if you finished writing task 1 for 10 minutes but the data written is incorrect you will never hit your target mark.

G – Go for task 2 first!
Task 2 in the IELTS writing section is easier to compose and is worth more mark than task 1. I am not saying that you should ignore the other component in this section, but making sure you completed the part which weighs more points to your mark is a wise choice.

Phlebotomy


PhotoCredit: outreachmobilelabs.com
Phlebotomy is a procedure that consists of venipuncture and withdrawal of blood. It is a safe outpatient method where blood is extracted from the vein through a cut or puncture. This procedure is performed by a nurse or technician called phlebotomist.

Purpose
Phlebotomy is performed for many reasons which include the following:
  1. To obtain sample for analysis and diagnosis.
  2. To treat polycythemia. Polycythemia is a condition where elevation or red blood cell volume is noted. Part of the treatment of this disorder is carrying out therapeutic phlebotomy.
  3. To decrease the total blood volume of patients with pulmonary edema.
  4. To remove blood from the body during blood donation.
  5. To analyze blood substances contained in blood before clearing a person for blood donation.
Safety Guidelines

  • Universal precautions are used with this procedure. Gloves should be worn when performing this procedure.
  • Prior to blood collection it is important that the one performing the procedure is properly trained and identified as licensed phlebotomist.
  • Properly identify your patient. Check the name tag and verify with the patient or nurse on duty.
  • Supplies should be checked for their integrity.
  • Label vials and tubes properly. Indicate date and time of extraction with the name of the patient clearly indicated.
  • Needles should be immediately disposed in an approved sharps container. They never be recapped and should only be used once.
  • Assess the patient for complications associated with the phlebotomy procedure.
Venipuncture Site Selection:
Although the larger and fuller median cubital and cephalic veins of the arm are used most frequently, the basilic vein on the dorsum of the arm or dorsal hand veins are also acceptable for venipuncture. Foot veins are a last resort because of the higher probability of complications.

Certain areas are to be avoided when choosing a site:



  • Extensive scars from burns and surgery - it is difficult to puncture the scar tissue and obtain a specimen.
  • The upper extremity on the side of a previous mastectomy - test results may be affected because of lymphedema.
  • Hematoma - may cause erroneous test results. If another site is not available, collect the specimen distal to the hematoma.
  • Intravenous therapy (IV) / blood transfusions - fluid may dilute the specimen, so collect from the opposite arm if possible. Otherwise, satisfactory samples may be drawn below the IV by following these procedures:
    • Turn off the IV for at least 2 minutes before venipuncture.
    • Apply the tourniquet below the IV site. Select a vein other than the one with the IV.
    • Perform the venipuncture. Draw 5 ml of blood and discard before drawing the specimen tubes for testing.
  • Lines - Drawing from an intravenous line may avoid a difficult venipuncture, but introduces problems. The line must be flushed first. When using a syringe inserted into the line, blood must be withdrawn slowly to avoid hemolysis.
  • Cannula/fistula/heparin lock - hospitals have special policies regarding these devices. In general, blood should not be drawn from an arm with a fistula or cannula without consulting the attending physician.
  • Edematous extremities - tissue fluid accumulation alters test results.

Description of Procedure
In this procedure, blood is extracted from a vein on the back of the hand or over the antecubital fossa. However, some tests require blood to be taken from an artery. In blood transfusion, donors are placed in a semirecumbent position and the skin over the antecubital fossa is carefully cleansed with an iodine preparation or antiseptic solution. A tourniquet or elastic band is applied around the arm to retain blood in the area and make the veins visible. After the phlebotomist selects an appropriate vein for blood extraction, venipucture is performed. – A needle is inserted into the vein and the tourniquet is released.
The appropriate amount of blood to be withdrawn widely varies. Blood donation and therapeutic phlebotomy require larger amount of blood than blood analysis. Blood donors usually give about 450 to 500 ml of blood per session. For laboratory analysis, the volume of blood needed depends on the type of test performed. Approximately, one or more 5 to 10 ml tubes of blood are withdrawn.

Withdrawal of 450 ml of blood takes less than 15 minutes. After the needle is removed, the donor is asked to hold the involved arm straight up and apply firm pressure on the site with sterile gauze for about 2 to 3 minutes or until the bleeding stops. The phlebotomy technician then places a bandage on the site.

Instructions After the Procedure
  • Within 1 to 2 minutes the donor is asked to remain in the position until they feel able to sit up. If weakness or faintness is experienced, the donor should rest for a longer time.
  • Foods and fluids are given when the donor sits up and is asked to remain for another 15 minutes.
  • Heavy lifting should be avoided for several hours.
  • Smoking should be avoided for an hour.
  • Alcoholic beverages should be avoided for 3 hours.
  • For 2 days, fluid intake should be increased and balanced diet should be practiced for 2 weeks.
NOTE: Always observe aseptic technique to protect your patient and yourself.

    • Compare body parts bilaterally for symmetry 
    II. Palpation
    • Use touch to assess resistance, resilience, roughness, texture and mobility 
    • Palpation may be either light or deep in pressure:
    1. Use light palpation to determine tenderness 
    2. Deep palpation usually depresses the area by 1 to 2 inches; use it to examine specific organs 
    •  Use palmar surface of fingers to determine position, texture, size, consistency and pulsation; also presence and shape of mass

    Methods
    • Direct: striking the body surface with two fingers 
    • Indirect: striking the middle finger of the non-dominant hand on the back surface with the fingers of the dominant hand rather than the body surface, while keeping the palm and remaining fingers of the body 
    • Character of percussion sounds depends on the density of the tissue being percussed 
    Percussion Sounds:
    • Tympany: drum like, loud, high pitch, moderate duration; usually found over space containing air such as the stomach 
    • Resonance: hollow sound of moderate to loud intensity; low pitch, long duration; usually heard over the lungs 
    • Hyperresonance: booming sound of very loud intensity; very low pitch, long duration; usually heard in the presence of trapped air (such as emphysematous lung) 
    • Flatness: flat sound of soft intensity; high pitch, short duration; usually heard over muscles 
    • Dullness: thud-like sound of soft intensity; high-pitch, moderate duration; usually heard over solid organs (such as heart, liver) 
    IV. Auscultation
    • Listening (with unassisted ear or stethoscope) to sounds made by the body 
    Assess presence of sound and their character 
    • Frequency (high or low pitch)

                • Lack of exercise
                • Substance abuse
                  1. tobacco
                  2. alcoholism
                  3. illicit drug use
                • Injury prevention
                  1. falls
                  2. seatbelts
                  3. suicide
                  4. multiple medications

              IV. Scoliosis Screening

              • Recommendations vary but generally accepted to perform screening at onset of adolescence
              • Significantly more prevalent in girls than boys
              • Early intervention important because untreated scoliosis can lead to disfigurement, impaired mobility, and cardiopulmonary complications
              • Technique - clothing should be removed from upper body
                1. While standing, check adolescent for asymmetry of shoulders, scapula, hips or waist
                2. Assess for misalignment of spinous processes - lateral curvature and convexity of thoracic spine indicate scoliosis
                3. With feet together and legs straight, have adolescent bend forward until back is parallel to floor; check for prominence of ribs on one side only and hip and leg asymmmetry - chest wall on side of convexity is prominent and scapula on side of convexity is elevated
              • Abnormalities are to be followed up by a health care provider and referral to orthopedist may be necessary for severe curvatures
              V. Testicular Self-Examinations
              • Monthly self-examination should begin in adolescence, since this is the highest risk group
              • Best time to perform exam is during or after a bath or shower when the scrotum is relaxed
              • Limited research to determine if regular examinations reduce death rate but they are strongly encouraged for men with risk factors such as
                1. family history of testicular cancer
                2. cryptochidism
                3. previous germ cell tumor in one testicle
              • Findings that should be reported to a health care provider include
                1. hard lumps or nodules
                2. change in size, shape or consistency of the testes

              F. Compliance
              • Definition: adherence to primary or secondary prevention recommendations
              • Factors influencing compliance
                  1.  Personal meaning and perceptions: knowledge, values, beliefs, outcome expectations
                  2. Social factors: environmental context, social relationships, social support, societal norms, economic resources
                  3. Deficiencies in the health care system: access, costs, wait time, monolingual services
                 G. Noncompliance
                •  An individual’s informed decision not to adhere to a therapeutic recommendation
                • Individual unable or unwilling to alter habitual behaviours or adopt new behaviours necessary to a prescribed therapeutic regimen 
                  TIMING OF MAMMOGRAMS 
                  • The National Cancer Institute (NCI) and the American Cancer Society differ in their recommendations for scheduling of mammograms 
                  • NCI recommends (2002): 
                  1. Women in their 40s should be screened every one (1) to two (2) years with mammography 
                  2. Women aged 50 and older should be screened every one (1) to two (2) years 
                  3. Women who are at higher than average risk of breast cancer should seek expert medical advice about whether they should begin screening before age 40 and the frequency of screening 
                  • The ACS guidelines for the detection of breast cancer in asymptomatic women (2002): 
                  1. Women 40 years of age and older should have a mammogram every year 
                  2. Women 40 years and older should have a physical examination of the breast every year, performed by a health care professional, such as a physician, physician assistant, nurse or nurse practitioner. This examination should take place near and preferable before, the annual mammogram 
                  3. Women 20-39 should have a physical examination of the breast every three (3) years, performed by a health care professional such as physician, physician assistant, nurse or nurse practitioner 
                  • BSE is an option for women starting in their 20s. Women should be told about the benefits and limitations of BSE. Women should report any breast changes to their health professional right away 


                  POINTS TO REMEMBER:
                  • Measure vital signs when the client is at rest
                  • Compare both sides of the body for symmetry
                  • Assess the systems related to the client's major complaint first
                  • Offer rest periods if client becomes tired
                  • Culture and religious beliefs may play a role in observed differences
                  • Warm hands and equipment such as stethoscope before touching client 
                  • Tell client what you are going to do before touching client
                  • Normal variations exist among clients and there is a range of normalcy for all physical findings
                  • Maintain the client's privacy throughout the examination
                  • Control for environmental factors which may distort findings
                  • Check equipment prior to exam for functioning
                  • Consider growth and developmental needs when assessing specific age groups
                  • Integrate client teaching throughout the exam

                  Measles


                  Definition:
                  Also known as Rubeola, an acute highly communicable infection characterized by fever, rashes and symptoms referable to upper respiratory tract; the eruption is preceded by about 2 days or coryza, during which stage grayish pecks (Koplik spots) may be found on the inner surface of the cheeks. A morbilliform rash appears on the 3rd or 4th day affecting face, body and extremities ending in branny desquamation.

                  Death is due to complication (e.g. secondary pneumonia, usually in children under 2 years old. Measles is severe among malnourished children with fatality of 95-100%. Infection confers life-long immunity.


                  Etiologic Agent: Filterable virus of Measles


                  Source of Infection: Secretion of nose, mouth and throat of infected persons.

                  Modes of Transmission:
                  1. Directly - by being sprayed with droplets emanating from a cough or sneeze
                  2. Indirectly - with articles newly contaminated with respiratory secretions from a patient.
                  3. Probably Airborne
                  • Incidence peak age is about 1-5 years old in congested urban areas and at early school age in less crowded sections.
                  • Immunity from the disease is long lasting while passive immunity transmitted transplacentally from mothers who have had measles may last about 5-6 months. The live attenuated vaccine confers almost lifelong immunity while the inactivated antigen gives an immunity 0f 6-18 months.
                  • Recent data suggests that cases is on the rise again in the United States and Canada due to the unsubstantiated claim that measles vaccine is associated with autism. In fact, various studies by government and non-government agencies disputing these claims.
                  Incubation Period:
                  • 10-12 days; one attack usually confers a lasting immunity
                  • 8 days shortest; 20 days longest
                  Period of Communicability:
                  • During the period of coryza or catarrhal symptoms - 9 days (from 4 days before and 5 days after rash appears)
                  Clinical Manifestations:
                  1. Pre-eruptive Stage
                    • patient is highly communicable
                    • fever
                    • catarrhal symptoms - start in the nasal cavities; then in the conjunctivae, oropharynx, progress to the bronchi resulting successively in rhinitis, conjunctivitis and then bronchitis.
                    • Respiratory symptoms - which appear first as a common cold, and sneezing nasal discharges, steadily progress into a distressing and annoying cough that persists up to convalescence.
                  2. Eruptive Stage/Stage of Skin Rashes
                    • exanthem sign - means eruption in the skin
                      • Maculopapular Rashes - appears 2-7  days after onset
                      • With high fever - increases steadily
                      • Anorexia and irritability - are disturbing particularly at the height of the fever
                      • Diarrhea, pruritis, lethargy and occipital lymphadenopathy
                  3. Stage of Convalescence
                    • Rashes - fade in the same manner as they appeared, from the face downwards, leaving a dirty brown pigmentation and finely granular which maybe noted for several days.
                    • Fever - gradually subsides as the eruptions disappear on the hands and feet
                  Tests:

                  • Usually none (most diagnosis is based clinically)
                  • Measles serology
                  • Viral culture (rarely done)

                  Treatment:
                  No therapy is indicated for uncomplicated measles, Gamma globulin although effective in prophylaxis is no value once symptoms are evidence. Patient should be monitored for the development of bacterial infections which should be treated with appropriate antibiotics on the basis of clinical and bacteriological findings.

                  The patient may also take over-the-counter medications such as acetaminophen (Tylenol, others) or nonsteroidal anti-inflammatory drugs (NSAIDs) to help relieve the fever that accompanies measles. Don’t give aspirin to children because of the risk of Reye’s syndrome — a rare but potentially fatal disease.

                  Maintain bedrest and provide quiet activities for the child. If there is sensitivity to light, keep room darkly lit. Remove eye secretions with warm saline or water. Encourage the patient not to rub the eyes. Administer antipyretic medication and tepid sponge baths as ordered. A cool mist vaporizer can be used to relieve cough. Apply antipruritic medication to prevent itching. Isolate child until fifth day of rash.


                  Prognosis


                  Prognosis is very good specially for those who do not develop complications like bronchitis, encephalitis (1 of 1000 cases), ear infections and pneumonia.

                  Methods of Prevention and Control
                  1. Avoid exposing children to any person with fever or with acute catarrhal symptoms
                  2. Isolation of cases from diagnosis until about 5-7 days after onset of rash
                  3. Disinfection of all articles soiled with secretion of nose and throat
                  4. Encourage by health department and by private physician of administration of measles immune globulin to susceptible infants and children under 3 years of age in families or institutions where measles occurs.
                  5. Live attenuated and inactivated measles virus vaccines have been tested and are available for use in children with no history of measles, at 9 months of age or soon thereafter
                  Public Health Nursing Responsibilities
                  1. Emphasize the need for immediate isolation when early catarrhal symptoms appear .
                  2. If immune serum of globulin is available (gamma Globulin), explain this to the family and refer to physician or clinic giving this service.
                  3. Observe closely the patient for complications during and after the acute stage.
                  4. Teach, demonstrate, guide and supervise adequate nursing care indicated.
                  5. Explain proceedings in proper disposal of nose and throat discharges.
                  6. Teach concurrent and terminal disinfection.
                  Nursing Care
                  1. Protect eyes of patients from glare of strong light as they are apt to be inflamed.
                  2. Keep the patient in an adequately ventilated room but free from drafts and chilling to avoid complications of pneumonia.
                  3. Teach, guide and supervise correct technique of giving sponge bath for comfort of patient.
                  4. Check for corrections of medication and treatment prescribed by physician.
