VRAAG 9   In die chloor-alkali-industrie word daar van ‘n elektrolitiese proses gebruik gemaak om ‘n pekeloplossing, NaCℓ (aq), te ontbind tot chloorgas, waterstofgas en ‘n natriumhidroksied oplossing. Die onderstaande diagram toon die membraansel wat vir hierdie proses gebruik word.   Regterklik op die onderstaande blou blokkie, om die Diagram vir Vraag 9 in ‘n aparte blad oop te maak.     9.1 Definieer elektrolise. (2) 9.2 Watter letter (A of B) verteenwoordig die: 9.2.1   Anode 9.2.2   Gee die naam van die gas wat vorm by die anode.  (1)  (1) 9.3 Gee die algemene netto reaksie vir hierdie proses.  (3)  9.4 Watter eienskap het gedeelte C wat die korrekte werking van hierdie sel verseker?  (1)  9.5 Beskryf die risiko’s wat gepaard gaan met die produksie van chloor in hierdie industriële proses en hoe hierdie risiko’s bestuur word?

Clinical Case for Questions 2, 3, 4 and 5 A 45-year old man presents with frequent “heartburn” due to the reflux of gastric acid secretions into the lower esophagus especially after eating or lying down. Endoscopic examination finds lesion located at the distal esophagus.  Biopsies taken from this area of the esophagus (approximately 4 cm proximal to the esophageal junction) reveal an abnormal epithelium for this region of the digestive tract. Case Question 2: The pathology and the change of the normal epithelial lining in the esophagus to an abnormal one described in the case above could be best characterized by which of the following terms?

Which common framework helps guide the nurse when prioritizing patient needs?

The nurse administers a specific medication to an older adult patient.  The patient has a diagnosis of dehydration which means a decrease in body water.  What does this place the patient at risk for?

Two hours after completing the initial assessment of a patient, the patient states they are now short of breath. What should the nurse assess at this time?

The nurse is documenting about a patient situation after the dressing has been changed, that includes the following data:  wound is red with an odor; skin is edematous around the wound; patient complains of pain 7/10 at wound site.  What is the most accurate documentation for the nurses note?

The nurse is completing the documentation of the hospitalized patient.  The nurse is aware to include:  Select all that apply.
