Which of the following anti-hypertensive medication belongs to the ACE Inhibitors?
Lisinopril.
Candesartan.
Metoprolol.
Amlodipine.
The Correct Answer is A
Lisinopril belongs to the class of drugs called angiotensin-converting enzyme (ACE) inhibitors. ACE inhibitors work by blocking the enzyme that converts angiotensin I to angiotensin II, a hormone that causes blood vessels to narrow and raise blood pressure. By inhibiting this enzyme, ACE inhibitors relax and widen the blood vessels, lower blood pressure, and improve blood flow to the heart and kidneys.
Choice B. Candesartan is wrong because it belongs to the class of drugs called angiotensin II receptor blockers (ARBs). ARBs work by blocking the action of angiotensin II on its receptors, preventing it from causing blood vessel constriction and high blood pressure. ARBs are similar to ACE inhibitors in their effects, but they do not affect the enzyme or the level of bradykinin, a peptide that can cause cough and angioedema as side effects of ACE inhibitors.
Choice C. Metoprolol is wrong because it belongs to the class of drugs called beta blockers. Beta blockers work by blocking the effects of adrenaline and other hormones that stimulate the heart and blood vessels, causing them to beat slower and with less force. Beta blockers lower blood pressure and reduce the workload on the heart.
Choice D. Amlodipine is wrong because it belongs to the class of drugs called calcium channel blockers. Calcium channel blockers work by blocking the entry of calcium into the muscle cells of the heart and blood vessels, causing them to relax and dilate. Calcium channel blockers lower blood pressure and improve blood flow to the heart.
Normal ranges for blood pressure vary depending on age, gender, and other factors, but generally, a systolic blood pressure (the top number) of less than 120 mmHg and a diastolic blood pressure (the bottom number) of less than 80 mmHg are considered normal for adults. A blood pressure of 130/80 mmHg or higher is considered high and may require treatment with medication.

Correct Answer is C
Explanation
This is because potassium sparing diuretics do not lower potassium levels in the blood, unlike other types of diuretics.Potassium is an essential electrolyte that serves nerve and muscular functions and is regulated by the kidneys.Low potassium levels can cause irregular heartbeats and other problems. Therefore, patients taking potassium sparing diuretics should avoid food sources that are high in potassium, such as bananas, avocados, spinach, and potatoes.
Choice A is wrong because thiazide diuretics, such as hydrochlorothiazide, can cause low potassium levels in the blood.
Patients taking thiazide diuretics may need to take potassium supplements or eat more potassium-rich foods to prevent hypokalemia.
Choice B is wrong because osmotic diuretics, such as mannitol, do not affect potassium levels in the blood.
They work by increasing the amount of water in the urine, but do not alter the electrolyte balance.
Osmotic diuretics are mainly used to treat cerebral edema and glaucoma.
Choice D is wrong because loop diuretics, such as furosemide, can also cause low potassium levels in the blood.
They work by inhibiting the reabsorption of sodium and water in the loop of Henle, a part of the kidney.
Loop diuretics are used to treat edema and heart failure.
Normal ranges for potassium in the blood are 3.5 to 5.0 millimoles per liter (mmol/L).
Correct Answer is C
Explanation
Urecholine is the brand name of bethanechol, a drug that belongs to the class of cholinergics, genitourinary.
It is used to treat urinary retention by stimulating the bladder to contract and empty.Urecholine can be taken orally or by injection.
Choice A is wrong because adrenergic drugs are those that activate the sympathetic nervous system, which is responsible for the fight-or-flight response.Adrenergic drugs can cause relaxation of the bladder and urinary retention, not contraction and emptying.
Choice B is wrong because anticholinergic drugs are those that block the action of acetylcholine, a neurotransmitter that mediates the parasympathetic nervous system, which is responsible for the rest-and-digest response.Anticholinergic drugs can also cause relaxation of the bladder and urinary retention, not contraction and emptying.
Choice D is wrong because adrenergic blockers are those that inhibit the action of adrenergic receptors, which are activated by adrenergic drugs or by the natural neurotransmitters norepinephrine and epinephrine.Adrenergic blockers can have various effects on the bladder depending on the type and location of the receptors they block, but they are not used to treat urinary retention.
