   2. Ba)Na+ only
      b) D
   3. Ca) Salt
      b) C
   4. Da) Cl- ions
      b) D
7. 7Polymorphisms known to increase blood pressure include gain of function mutations to (Choose 2)

   1. AAngiotensinogen
   2. BENaC (e.g. in Liddle's syndrome)
   3. CNKCC1
   4. DAQP2
8. 8Which of the following is NOT a cause of Secondary Hypertension

   1. APheochromocytomas
   2. BRenal Disease
   3. CRenal Artery Stenosis
   4. DRenal Artery Dilation
9. 9Pheochromocytomas is a tumour of the (a), this leads to an increase in (b), which causes a rise in (c) raising blood pressure.

   1. Aa) adrenal medulla
      b) chromaffin
      c) adrenaline
   2. Ba) adrenal cortex
      b) chromaffin
      c) adrenaline
   3. Ca) adrenal medulla
      b) adrenaline
      c) chromaffin
   4. Da) adrenal cortex
      b) adrenaline
      c) chromaffin
10. 10In renal artery stenosis, the kidney is confused by the (a) in blood flow causing it to assume (b).
    This leads to the (c) of blood pressure by the renin-angiotensin-aldosterone axis.

    1. Aa) decreased
       b) low blood pressure
       c) increase
    2. Ba) increased
       b) high blood pressure
       c) decrease
    3. Ca) decreased
       b) high blood pressure
       c) increase
    4. Da) decreased
       b) low blood pressure
       c) decrease

11. 11Which of these is ARE a consequences of hypertension (3)

    4. DMyocardial infarction / Stroke
    5. EClearer vision (in the impaired)
12. 12Treatments for hypertension include lifestyle changes (diet, exercise etc.); diuretics such as thiazide which decreases Na+ reuptake; and sympatholytics

    1. ATrue
    2. BFalse
13. 13Beta Blockers such as propranolol decrease heart contractions. This helps reduce hypertension.

    1. ATrue
    2. BFalse
14. 14Alpha blockers such as clonidine and prazosin increase CNS sympathetic output to the heart and hence TPR to reduce hypertension.

    1. ATrue
    2. BFalse
15. 15(X) inhibitors and angiotensin II receptor blockers (called (Y) are also used in the treatment of hypertension.

    1. AX- ACE
