The main class of drug for the treatment and management of Angina attack is what?

Fatty oxidase enzyme inhibitors.

Beta adrenergic blockers.

Nitrates.

Statins.

Answer and Explanation

The Correct Answer is C

Nitrates are a class of drugs that help to widen the blood vessels and increase blood flow to the heart muscle, which reduces the chest pain or discomfort caused by angina. Nitrates can be taken as a mouth spray or tablets that dissolve under the tongue during an angina attack, or as a preventive measure before physical activity.

Choice A is wrong because fatty oxidase enzyme inhibitors are not a real class of drugs.

Fatty acid oxidation is a process that breaks down fats for energy, and it is not related to angina treatment.

Choice B is wrong because beta adrenergic blockers are not the main class of drugs for angina treatment, although they can be used to prevent angina attacks by slowing down the heart rate and reducing the blood pressure.

Beta blockers block the effects of epinephrine (adrenaline) on the heart and blood vessels, which reduces the oxygen demand of the heart.

Choice D is wrong because statins are not used to treat angina attacks, but to lower the cholesterol levels in the blood and prevent plaque buildup in the arteries.

Statins can help reduce the risk of heart attacks and strokes in people with angina, but they do not relieve angina symptoms.

Correct Answer is B

Explanation

Nitroglycerin is a medication that dilates the blood vessels and improves blood flow to the heart. It is used to treat angina, a condition that causes chest pain due to reduced oxygen supply to the heart. However, nitroglycerin can lose its effectiveness over time if it is used continuously. This is called tolerance, and it means that the patient will need higher doses of the medication to achieve the same relief. To avoid tolerance, patients who use transdermal nitroglycerin patches are instructed to remove the patch at bedtime and apply a new one in the morning. This creates a nitrate-free interval of about 8 to 12 hours, which allows the body to restore its sensitivity to nitroglycerin.

Choice A is wrong because an allergic response is not a common side effect of nitroglycerin. Some patients may experience skin irritation or rash at the site of application, but this is usually mild and does not require discontinuation of the medication.

Choice C is wrong because overdosage is unlikely with transdermal nitroglycerin patches. The patches deliver a controlled amount of nitroglycerin through the skin over a period of time. The risk of overdosage is higher with other forms of nitroglycerin, such as tablets or sprays, which are taken as needed for acute angina attacks.

Choice D is wrong because forgetting to remove the patch in the morning is not a serious problem. The patch will continue to deliver nitroglycerin until it is removed, but it will not cause harm to the patient. However, it may reduce the effectiveness of the next patch if there is no nitrate-free interval between them.

A. Positive chronotropy and negative inotropy. B. Negative inotropy and negative chronotropy. C. Positive inotropy and negative chronotropy. D. Positive inotropy and positive chronotropy.

Correct Answer is C

Explanation

Positive inotropy and negative chronotropy.Digoxin is a cardiac glycoside that increases the force of the heart contractions (positive inotropy) and slows down the heart rate (negative chronotropy).

Choice A is wrong because positive chronotropy means increasing the heart rate, which is the opposite of what digoxin does.

Choice B is wrong because negative inotropy means decreasing the force of the heart contractions, which is also the opposite of what digoxin does.

Choice D is wrong because positive chronotropy means increasing the heart rate, which is not what digoxin does.

Digoxin is used to treat heart failure and atrial fibrillation, a type of irregular heartbeat.It has a narrow therapeutic window, meaning that the dose must be carefully adjusted to avoid toxicity or ineffectiveness.
