In which condition is leg pain produced upon increased activity and ischemia to tissues, but then the pain is reduced with rest?
Intermittent claudication.
Sporadic ischemia.
Angina.
Paresthesia.
The Correct Answer is A
Intermittent claudication is a condition where leg pain is produced upon increased activity and ischemia to tissues, but then the pain is reduced with rest. This is because the lack of oxygen to the muscles causes pain, and resting allows the blood flow to resume.
Choice B, sporadic ischemia, is wrong because it is not a specific condition, but a general term for reduced blood supply to a tissue or organ.
Choice C, angina, is wrong because it is a chest pain caused by reduced blood flow to the heart, not the legs.
Choice D, paresthesia, is wrong because it is a sensation of tingling, numbness, or prickling in the skin, not pain.
It can be caused by various conditions, such as nerve damage, diabetes, or Raynaud’s disease.

Correct Answer is C
Explanation
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 D
Explanation
Alpha 1 adrenergic blocking agents have a vasodilating effect and can be used for the management of hypertension.They work by preventing the hormone norepinephrine from tightening the muscles in the walls of smaller arteries and veins, thus lowering the blood pressure.Some examples of alpha 1 blockers are doxazosin, prazosin, and terazosin.
Choice A is wrong because alpha 3 adrenergic blockers do not exist.There are only two subtypes of alpha receptors: alpha 1 and alpha 2.
Choice B is wrong because alpha 2 adrenergic antagonists are not used for hypertension.They are used for conditions like attention deficit hyperactivity disorder (ADHD) and opioid withdrawal.Alpha 2 antagonists block the negative feedback mechanism of norepinephrine release, thus increasing the amount of norepinephrine in the blood and raising the blood pressure.
Choice C is wrong because alpha 1 adrenergic agonists have the opposite effect of alpha 1 blockers.They stimulate the alpha 1 receptors and cause vasoconstriction, which increases the blood pressure.Alpha 1 agonists are used for conditions like nasal congestion and hypotension.
