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
Phenazopyridine hydrochloride (Pyridium) is a urinary tract analgesic that can relieve the pain, burning, and discomfort caused by infection or irritation of the urinary tract.However, it can also cause some side effects, one of which is changing the color of bodily secretions to reddish orange. This is due to the excretion of the drug in the urine, saliva, sweat, and tears.The color change is harmless and usually disappears when the drug is stopped.
Choice A is wrong because phenazopyridine does not change bodily secretions to alkaline.In fact, it may interfere with the urine test that measures acidity (pH) and glucose.
Choice B is wrong because phenazopyridine does not change bodily secretions to pinkish.However, some other drugs, such as rifampin and doxorubicin, may cause urine to turn red or pink.
Choice D is wrong because phenazopyridine does not change bodily secretions to black.However, some other drugs, such as metronidazole and nitrofurantoin, may cause urine to turn brown or dark yellow.
Some other common side effects of phenazopyridine include headache, dizziness, indigestion, and stomach pain.Some serious side effects include skin itching, interference with the oxygen-carrying capacity of red blood cells, hemolytic anemia, and renal and hepatic toxicity.
These problems are more common in people who have existing kidney problems or take more than recommended.If you experience any of these symptoms, stop taking phenazopyridine hydrochloride and talk to a healthcare provider right away.
Correct Answer is A
Explanation
Food high in potassium should be avoided for clients taking ACE inhibitors. ACE inhibitors are drugs that block the conversion of angiotensin I to angiotensin II, which is a potent vasoconstrictor and also stimulates the secretion of aldosterone. Aldosterone is a hormone that increases the reabsorption of sodium and water and the excretion of potassium in the kidneys. By inhibiting angiotensin II, ACE inhibitors lower blood pressure and reduce the loss of potassium. However, this can also lead to hyperkalemia, which is a high level of potassium in the blood that can cause cardiac arrhythmias and muscle weakness.Therefore, clients taking ACE inhibitors should limit their intake of foods that are rich in potassium, such as bananas, oranges, tomatoes, potatoes, spinach, beans, nuts, and salt substitutes.
Choice B is wrong because a low sodium diet is recommended for clients taking ACE inhibitors.
A low sodium diet can help lower blood pressure and reduce fluid retention, which are beneficial effects for clients with hypertension, heart failure, or chronic kidney disease.A low-potassium diet should aim for potassium intake of less than 50 or 75 mmol/day and sodium intake of less than 60 mmol/day for hypertensive patients with chronic kidney disease.
Choice C is wrong because adequate fluid intake is not contraindicated for clients taking ACE inhibitors.
Adequate fluid intake can help prevent dehydration and maintain kidney function, especially in patients with diabetes or nephropathy.However, excessive fluid intake may worsen heart failure or edema in some patients, so fluid intake should be individualized and monitored according to the patient’s condition and response to therapy.
Choice D is wrong because foods low in potassium are not harmful for clients taking ACE inhibitors.
Foods low in potassium do not affect the serum potassium level or the risk of hyperkalemia in clients taking ACE inhibitors.However, foods low in potassium may not provide enough dietary potassium for normal cellular functions, so a balanced diet that includes moderate amounts of potassium-rich foods is advisable.
