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 D
Explanation
Taking a loop diuretic with supper is not advisable because it can cause nocturia, which is the need to urinate frequently at night. This can disrupt sleep and affect quality of life.Loop diuretics should be taken in the morning or early afternoon to avoid this problem.
Choice A is wrong because weighing oneself each day before breakfast is a good way to monitor fluid balance and detect any signs of fluid retention or dehydration.This can help adjust the dose of the loop diuretic as needed.
Choice B is wrong because contacting the healthcare provider if shortness of breath returns is a sensible precaution and indicates awareness of the symptoms of worsening heart failure.Shortness of breath is caused by fluid accumulation in the lungs, which loop diuretics help to prevent or reduce.
Choice C is wrong because having a banana with breakfast every morning is a good source of potassium, which can help prevent hypokalemia, a common side effect of loop diuretics.Loop diuretics increase the excretion of potassium in the urine, which can lead to low blood levels of potassium and cause muscle weakness, cramps, fatigue, arrhythmias, and increased sensitivity to digoxin.
Correct Answer is B
Explanation
PT stands for prothrombin time, which is a measure of how long it takes the blood to clot. INR stands for international normalized ratio, which is a standardized way of reporting the PT result. Warfarin is a blood thinner that works by slowing down the clotting process.Therefore, people who take warfarin need to have their PT/INR monitored regularly to make sure they are getting the right dose and not bleeding too much or too little.
Choice A is wrong because PTT stands for partial thromboplastin time, which is another measure of blood clotting that is not affected by warfarin.PTT is used to monitor heparin, another type of blood thinner.
Choice C is wrong because CBC stands for complete blood count, which is a test that measures the number and types of cells in the blood, such as red blood cells, white blood cells and platelets.CBC can show if there is anemia, infection or bleeding, but it does not measure the effect of warfarin on clotting.
Choice D is wrong because LFTs stand for liver function tests, which are a group of tests that check how well the liver is working.
LFTs can show if there is liver damage or disease, which can affect how warfarin is metabolized and cleared from the body.However, LFTs do not directly measure the effect of warfarin on clotting.
The normal range for PT/INR varies depending on the laboratory and the reason for taking warfarin.
Generally, the normal range for PT is 10 to 13 seconds, and the normal range for INR is 1.1 or below for healthy people.For people taking warfarin, the target INR range depends on their condition and risk factors, but it is usually between 2.0 and 3.0.
