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
This is because nitroglycerin patches can cause tolerance if they are used continuously, which reduces their effectiveness in preventing angina attacks. Removing the patch each evening allows the body to restore its sensitivity to the drug.
Choice A is wrong because nitroglycerin patches should be applied every 24 hours, not every 48 hours.
Applying a new patch every 48 hours would result in inadequate blood levels of the drug and increased risk of angina.
Choice B is wrong because nitroglycerin patches should not be cut in half or altered in any way.
Cutting the patch would compromise the integrity of the drug delivery system and could lead to unpredictable or excessive doses of the drug.
Choice C is wrong because nitroglycerin patches should not be taken off for 30 minutes if a headache occurs.
Headache is a common side effect of nitroglycerin due to its vasodilating action, but it usually subsides with continued use.
Taking off the patch for 30 minutes could increase the risk of angina by interrupting the steady blood levels of the drug.
The nurse should advise the client to take an analgesic such as acetaminophen for headache relief.
Correct Answer is D
Explanation
Thrombolytic agents are a classification of drugs that dissolve blood clots by activating the enzyme plasmin, which breaks down the proteins (fibrins) that form clots. They are used for serious conditions, such as stroke, pulmonary embolism, or heart attack when the blood flow needs to be restored quickly.
Choice A is wrong because salicylates are anti-inflammatory drugs that inhibit the synthesis of prostaglandins, which are involved in inflammation and pain. They also have antiplatelet effects, but they do not dissolve existing clots.
Choice B is wrong because antiplatelets are drugs that prevent platelets from sticking together and forming clots. They are used to prevent clotting in conditions such as coronary artery disease, stroke, or peripheral arterial disease. They do not dissolve existing clots either.
Choice C is wrong because anticoagulants are drugs that prevent clots from forming by interfering with the clotting factors that are normally present in the blood.
They are used to treat or prevent conditions such as deep vein thrombosis, pulmonary embolism, or atrial fibrillation. They do not dissolve existing clots.
Normal ranges for clotting factors vary depending on the laboratory and the method used, but some common values are:
• Prothrombin time (PT): 11 to 13 seconds
• International normalized ratio (INR): 0.8 to 1.2
• Activated partial thromboplastin time (aPTT): 25 to 35 seconds
• Fibrinogen: 200 to 400 mg/dL
• D-dimer: less than 0.5 mcg/mL
