QuestionChoice
Lisinopril is an ACE inhibitor and hyperkalaemia, not hypokalaemia, is an adverse effect of this class of medications. ACE inhibitors block the action of angiotensin II, reducing the secretion of aldosterone. Aldosterone acts to remove potassium from the body whilst retaining sodium and water. Drugs such as loop diuretics (eg furosemide) can cause hypokalaemia.

QuestionChoice
Lisinopril is an ACE inhibitor and hyperkalaemia, not hypocalcaemia, is an adverse effect of this class of medications. ACE inhibitors block the action of angiotensin II, reducing the secretion of aldosterone. Aldosterone acts to remove potassium from the body whilst retaining sodium and water. Drugs such as bisphosphonates and denosumab (both of which are used to treat osteoporosis) can cause hypocalcaemia.

Hypocalcaemia
QuestionChoice
Lisinopril is an ACE inhibitor and hyperkalaemia, not hyponatraemia, is an adverse effect of this class of medications. ACE inhibitors block the action of angiotensin II, reducing the secretion of aldosterone. Aldosterone acts to remove potassium from the body whilst retaining sodium and water. Drugs such as diuretics (especially thiazide diuretics) and carbamazepine (an anti-epileptic) can cause hyponatraemia.

c
Hyponatraemia
QuestionChoice
This is the correct answer. Lisinopril is an ACE inhibitor and hyperkalaemia is an adverse effect of this class of medications. ACE inhibitors block the action of angiotensin II, reducing the secretion of aldosterone. Aldosterone acts to remove potassium from the body whilst retaining sodium and water.

Hyperkalaemia
QuestionChoice
Lisinopril is an ACE inhibitor and hyperkalaemia, not hypernatraemia, is an adverse effect of this class of medications. ACE inhibitors block the action of angiotensin II, reducing the secretion of aldosterone. Aldosterone acts to remove potassium from the body whilst retaining sodium and water. Drugs such as NSAIDs can cause hypernatraemia.
