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 digoxin can cause bradycardia (slow heart rate) as a side effect, which can be dangerous and require dose adjustment or discontinuation of the medication.Digoxin helps make the heart beat stronger and with a more regular rhythm by inhibiting sodium-potassium ATPase in cardiac cells.It is used to treat heart failure and atrial fibrillation.
Choice A is wrong because increasing sodium intake can worsen fluid retention and exacerbate heart failure symptoms.Patients with heart failure should follow a low-sodium diet to reduce the workload on the heart.
Choice B is wrong because checking pulse rate for 30 seconds and multiplying result by 2 is not accurate enough to monitor the effects of digoxin.
Patients taking digoxin should check their pulse rate for one full minute before taking each dose and record it daily.If the pulse rate is too fast or too slow, they should contact their provider.
Choice C is wrong because taking digoxin with food may reduce its absorption and effectiveness.Digoxin should be taken on an empty stomach, at least one hour before or two hours after a meal.If nausea occurs, it may be a sign of digoxin toxicity and should be reported to the provider.
Correct Answer is B
Explanation
Class IV antidysrhythmics or calcium channel blockers decrease the flow of calcium ions into cardiac and vascular smooth muscle cells, thus decreasing heart rate and contractions.By reducing the calcium influx, they also decrease the slope of phase 0 and 4 and prolong phase 2 of the cardiac action potential.This results in vasodilation, reduced myocardial oxygen demand, and decreased conduction through the AV node.
Choice A is wrong because calcium channel blockers do not increase blood vessel spasm, but rather cause vasodilation.
Choice C is wrong because calcium channel blockers do not decrease refractory period, but rather prolong it by extending phase 2 of the cardiac action potential.
Choice D is wrong because calcium channel blockers do not increase heart rate, but rather decrease it by slowing down the pacemaker activity and AV nodal conduction.
Normal ranges for heart rate are 60 to 100 beats per minute, and for blood pressure are 120/80 mmHg or lower.
