Which range of systolic blood pressure is classified as stage 1 hypertension?
140 to 159.
130 to 139.
110 to 119.
120 to 139.
The Correct Answer is B
This range of systolic blood pressure is classified as stage 1 hypertension according to the American College of Cardiology and the American Heart Association. Stage 1 hypertension is when blood pressure consistently ranges from 130 to 139 systolic or 80 to 89 mm Hg diastolic. At this stage of high blood pressure, health care professionals are likely to prescribe lifestyle changes and may consider adding blood pressure medication based on your risk of atherosclerotic cardiovascular disease, or ASCVD, such as heart attack or stroke.
Choice A is wrong because 140 to 159 is the range for stage 2 hypertension, which is more severe than stage 1.
Stage 2 hypertension is when blood pressure consistently is 140/90 mm Hg or higher. At this stage of high blood pressure, health care professionals are likely to prescribe a combination of blood pressure medications and lifestyle changes.
Choice C is wrong because 110 to 119 is the range for normal blood pressure.
Normal blood pressure is when systolic blood pressure is less than 120 mm Hg and diastolic blood pressure is less than 80 mm Hg. If your results fall into this category, stick with heart-healthy habits like following a balanced diet and getting regular exercise.
Choice D is wrong because 120 to 139 is not a valid range for systolic blood pressure.
It includes two different categories: elevated and stage 1 hypertension.
Elevated blood pressure is when readings consistently range from 120-129 systolic and less than 80 mm Hg diastolic. People with elevated blood pressure are likely to develop high blood pressure unless steps are taken to control the condition. Stage 1 hypertension, as explained above, is when systolic blood pressure ranges from 130 to 139 or diastolic blood pressure ranges from 80 to 89.
The normal range for systolic blood pressure is less than 120 mm Hg. The normal range for diastolic blood pressure is less than 80 mm Hg.

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.
Correct Answer is C
Explanation
ACE inhibitors are a type of medication used to treat high blood pressure and heart failure. They work by blocking the production of a hormone called angiotensin II, which narrows the blood vessels and increases blood pressure.By preventing this hormone from acting, ACE inhibitors lower blood pressure and reduce the workload on the heart. One of the most common side effects of ACE inhibitors is a dry cough, which occurs in 12–19% of people who take them. The cough is caused by the accumulation of a substance called bradykinin, which is normally broken down by angiotensin-converting enzyme (ACE).When ACE is inhibited, bradykinin levels increase and cause irritation and inflammation in the airways.
Choice A is wrong because decreased white blood cells are not a common side effect of ACE inhibitors.
However, some people may develop a condition called neutropenia, which is a low level of a type of white blood cell called neutrophils.This can increase the risk of infections and may require stopping the medication.
Choice B is wrong because swelling of the face and lips is not a common side effect of ACE inhibitors.
However, some people may develop a rare but serious allergic reaction called angioedema, which is a swelling of the deeper layers of the skin and mucous membranes.
This can affect the face, lips, tongue, throat, or other parts of the body and can cause difficulty breathing or swallowing.Angioedema can be life-threatening and requires immediate medical attention.
Choice D is wrong because renal failure is not a common side effect of ACE inhibitors.
However, some people may experience a decrease in kidney function or an increase in blood levels of creatinine, which is a waste product filtered by the kidneys.
