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 C
Explanation
Anticoagulants are medicines that increase the time it takes for blood to clot.They do not dissolve existing clots, but they can stop them from getting bigger or prevent new clots from forming.Anticoagulants work by interfering with different steps of the blood coagulation pathway, which is a complex process that involves many clotting factors.
Choice A is wrong because anticoagulants do not dissolve existing clots.To dissolve clots, you need medicines called thrombolytics or fibrinolytics, which break down the fibrin that holds the clots together.
Choice B is wrong because anticoagulants do not transport platelets.
Platelets are blood cells that help with clotting by sticking together and forming a plug at the site of an injury.Anticoagulants may affect the function of platelets, but they do not move them around.
Choice D is wrong because anticoagulants do not increase blood viscosity.
Viscosity is a measure of how thick and sticky a fluid is.
Anticoagulants are sometimes called blood thinners, but they do not actually change the viscosity of blood.They just make it less likely to clot.
Normal ranges for blood clotting tests vary depending on the type of test and the laboratory that performs it.
Some common tests and their normal ranges are:
• Prothrombin time (PT): 11 to 13.5 seconds
• International normalized ratio (INR): 0.8 to 1.2
• Activated partial thromboplastin time (aPTT): 25 to 35 seconds
• Anti-factor Xa: 0.3 to 0.7 units/mL
• D-dimer: less than 0.5 mcg/mL
Correct Answer is D
Explanation
Angiotensin receptor blockers (ARBs) are a class of drugs that block the action of angiotensin II, a hormone that causes blood vessels to constrict and raise blood pressure. Examples of ARBs include losartan, valsartan, candesartan, and irbesartan.ARBs are used to treat hypertension, heart failure, and chronic kidney disease.
Choice A is wrong because calcium channel blockers (CCBs) are a class of drugs that prevent calcium from entering the cells of the heart and blood vessels, causing them to relax and lower blood pressure.
Examples of CCBs include amlodipine, diltiazem, verapamil, and nifedipine.CCBs are used to treat hypertension, angina, and arrhythmias.
Choice B is wrong because beta blockers are a class of drugs that reduce the heart rate and force of contraction, lowering the cardiac output and blood pressure.
Examples of beta blockers include atenolol, metoprolol, propranolol, and bisoprolol.Beta blockers are used to treat hypertension, angina, heart failure, and arrhythmias.
Choice C is wrong because platelet inhibitors are a class of drugs that prevent platelets from clumping together and forming blood clots.
Examples of platelet inhibitors include aspirin, clopidogrel, ticagrelor, and prasugrel.Platelet inhibitors are used to prevent or treat cardiovascular events such as heart attack or stroke.
Choice E is wrong because ACE inhibitors are a class of drugs that inhibit the enzyme that converts angiotensin I to angiotensin II, reducing the production of this vasoconstrictor hormone.
Examples of ACE inhibitors include lisinopril, enalapril, ramipril, and captopril.ACE inhibitors are used to treat hypertension, heart failure, and chronic kidney disease.
