  1. 1Which of the following will cause an increase in blood pressure?
    1. AIncreased parasympathetic nerve system activity at the sinoatrial node
    2. BVasodilatation of the peripheral arterioles
    3. CA decrease in circulating blood volume
    4. DIncreased activation of cardiac B1 (beta 1) adrenoreceptors
  2. 2Which of the following statements about the renin-angiotensin system is incorrect?
    1. AAngiotensin II is the major bioactive peptide
    2. BRenin is released from the kidney in response to an increase in blood pressure
    3. CActivation of the system can increase aldosterone production and Na+ retention
    4. DIncreased activity of ACE can lead to enhanced peripheral vasoconstriction

    3. CHypertension is usually due to a specific underlying pathology
    4. DHypertension is influenced by both genetic and lifestyle factors
  4. 4ACE inhibitors such as Catopril act by:
    1. ACompetitively antagonising AT1 receptors
    2. BDecreasing the formation of angiotensinogen
    3. CIncreasing the activity of renin
    4. DReducing the conversion of angiotensin I into angiotensin II

  6. 6Which of the following statements about anti-hypertensive drugs is INCORRECT?
    1. AAtenolol will oppose the increases in heart rate and contractility caused by SNS activation
    2. BHydrochlorothiazides act in the distal tubule to increase Na+ reabsoprtion
    3. CIrbesartan antagnoises AT1 receptors to reduce vasoconstriction
    4. DPrazosin reduces blood pressure by antagonising adrenoreceptors in the vasculature
  7. 7Eplerenone:
    1. AIncreases Na+ reabsorption in the collecting duct
    2. BProduces a large diuresis
    3. CReduces K+ excretion
    4. DIs a positive inotrope
  8. 8Which of the following does NOT contribute to the mechanism of action of Digoxin?

    2. BInhibition of the Na+-K+-ATPase
    3. CAn increase in cytoplasmic Ca2+
    4. DIncrease activity of the Na+-Ca2+ exchanger
  9. 9Organic nitraties such as Glyceryl Trinitrate do all of the following except:
    1. ACause vasodilation
    2. BIncrease cardiac contractility
    3. CReduce preload

    2. BCan be transported from peripheral tissues to the liver by HDL
    3. CCirculates independently in the bloodstream
    4. DCan be synthesised in the adipose tissue
