Resource summary

Question 1

Question
90% of hypertension is ‘primary’ which means of [blank_start]unknown[blank_end] cause. 'Secondary’ is due to kidney disease, Cushing syndrome, thyroid disease, and drug-induced. Drug treatments include drugs to: [blank_start]dilate[blank_end] blood vessels, reduce [blank_start]constriction[blank_end] of vessels, reduce blood [blank_start]volume[blank_end], and reduce cardiac load.
Answer
  • unknown
  • dilate
  • constriction
  • volume

Question 2

Question
If we give a Beta1 blocker then we anticipate a decrease in heart rate.
Answer
  • True
  • False

Question 3

Question
If we give an alpha blocker then we anticipate vasoconstriction.
Answer
  • True
  • False

Question 4

Question
Non-selective β−blockers (e.g. Propanolol) should be avoided in asthmatics as they may constrict the airways.
Answer
  • True
  • False

Question 5

Question
The RAAS system maintains fluids and electrolyte balances. Renin is released from the arterioles near the [blank_start]glomerulus[blank_end], in response to reduced [blank_start]blood pressure[blank_end] or reduced renal blood [blank_start]flow[blank_end]. Renin: - Converts [blank_start]angiotensinogen[blank_end] to [blank_start]angiotensin[blank_end] - Angiotensin is converted to [blank_start]angiotensin II[blank_end] by the [blank_start]ACE[blank_end] ATII causes [blank_start]vasoconstriction[blank_end] and aldosterone release from the adrenals. Aldosterone promotes [blank_start]K+[blank_end] excretion in exchange for [blank_start]Na+ and water[blank_end] reabsorption to maintain plasma volume and cardiac output (ie to retain volume and raise BP.)
Answer
  • glomerulus
  • blood pressure
  • flow
  • angiotensin
  • angiotensinogen
  • angiotensin II
  • ACE
  • vasoconstriction
  • K+
  • Na+ and water

Question 6

Question
If we give an ACE inhibitor or an angiotensin II receptor blocker (ARB) we anticipate vasodilation.
Answer
  • True
  • False

Question 7

Question
Side effects of ACE inhibitors and ARBs: - dizziness/postural [blank_start]hypotension[blank_end] - [blank_start]hyper[blank_end]kalaemia (increase K+) - ACEI can cause [blank_start]cough[blank_end] due to build up of bradykinin (broken down by ACE) [blank_start]Hypotension and hyperkalemia[blank_end] are also side effects of thiazide diuretics.
Answer
  • hypotension
  • hyper
  • hypo
  • cough
  • Hypotension and hyperkalemia

Question 8

Question
Which of these is not a side effect of calcium channel blockers?
Answer
  • Peripheral oedema
  • Constipation
  • Dizziness/postural hypotension
  • Flushing
  • Headache
  • Nausea

Question 9

Question
Non-dihydropyridine calcium channel blockers can cause bradycardia (Caution if patient also on a β-blocker).
Answer
  • True
  • False
