Certain factors place us at risk for the development of cardiovascular disease.
Which of the following are modifiable risk factors? Select all that apply.
Cholesterol level.
Blood pressure.
Family history.
Weight.
Smoking.
Correct Answer : A,B,D,E
These are all modifiable risk factors for cardiovascular disease, meaning they can be changed through lifestyle choices or medication. Cholesterol level, blood pressure, weight, and smoking all affect the health of the heart and blood vessels, and can increase the risk of developing conditions such as atherosclerosis, hypertension, heart attack, or stroke.
Choice C, family history, is not a modifiable risk factor for cardiovascular disease.
It is a non-modifiable risk factor, meaning it cannot be changed and is determined by genetics.
Having a family history of cardiovascular disease can increase the risk of developing it, but it does not mean that it is inevitable. Other non-modifiable risk factors include sex, older age, race and ethnicity.
Some normal ranges for the modifiable risk factors are:
• Cholesterol level: total cholesterol should be less than 200 mg/dL; LDL cholesterol should be less than 100 mg/dL; HDL cholesterol should be more than 40 mg/dL for men and more than 50 mg/dL for women; triglycerides should be less than 150 mg/dL.
• Blood pressure: normal blood pressure is less than 120/80 mmHg; elevated blood pressure is 120-129/less than 80 mmHg; hypertension stage 1 is 130-139/80-89 mmHg; hypertension stage 2 is 140 or higher/90 or higher mmHg.
• Weight: body mass index (BMI) is a measure of weight relative to height; normal BMI is 18.5-24.9 kg/m2; overweight BMI is 25-29.9 kg/m2; obese BMI is 30 or higher kg/m2.
• Smoking: smoking any amount of tobacco products can harm the cardiovascular system; quitting smoking can lower the risk of cardiovascular disease and improve overall health.

Correct Answer is C
Explanation
This is because potassium sparing diuretics do not lower potassium levels in the blood, unlike some other types of diuretics. Potassium is an important electrolyte that helps regulate nerve and muscle functions, especially the heart. Low potassium levels can cause irregular heartbeats and other problems.Therefore, people who take diuretics should avoid foods that are high in potassium, such as bananas, oranges, tomatoes, and potatoes, unless they are taking potassium sparing diuretics.
Choice A is wrong because thiazide diuretics, such as hydrochlorothiazide, can cause low potassium levels in the blood and increase the risk of arrhythmias.
People who take thiazide diuretics may need to take potassium supplements or eat more potassium-rich foods.
Choice B is wrong because osmotic diuretics, such as mannitol, do not affect potassium levels in the blood.
They work by increasing the amount of water in the urine, but do not alter the electrolyte balance.
Osmotic diuretics are mainly used to treat brain swelling or glaucoma.
Choice D is wrong because loop diuretics, such as lasix, can also cause low potassium levels in the blood and increase the risk of arrhythmias.
People who take loop diuretics may also need to take potassium supplements or eat more potassium-rich foods.
Normal ranges for potassium in the blood are 3.5 to 5.0 millimoles per liter (mmol/L).
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.
