The patient with peripheral vascular disease such as Raynaud's disease should avoid what?
Wearing warm mitten gloves.
Wearing socks.
Exposure to cold temperatures.
Engaging in regular exercise.
The Correct Answer is C
Exposure to cold temperatures should be avoided by the patient with peripheral vascular disease such as Raynaud’s disease.
This is because cold temperatures can trigger vasospasm, which is a sudden narrowing of the small arteries in the fingers or toes, limiting blood flow and causing pain, numbness and color changes.
Choice A is wrong because wearing warm mitten gloves can help prevent or reduce the severity of Raynaud’s attacks by keeping the hands warm.
Choice B is wrong because wearing socks can also help protect the feet from cold exposure and prevent or reduce Raynaud’s attacks.
Choice D is wrong because engaging in regular exercise can improve blood circulation and reduce the frequency and duration of Raynaud’s attacks. However, exercise should be done with caution and proper clothing to avoid injury or frostbite to the affected areas.
Normal ranges for peripheral vascular disease are not applicable, as it is a condition that affects the blood vessels and not a specific blood test or measurement.
However, some tests that can help diagnose peripheral vascular disease or its underlying causes are blood pressure measurement, ankle-brachial index, Doppler ultrasound, angiography, blood tests for cholesterol, glucose, clotting factors and inflammatory markers.

Correct Answer is B
Explanation
Lifestyle is the greatest contributing factor that can lead to many diseases, especially noncommunicable diseases (NCDs) such as cardiovascular diseases, cancers, chronic respiratory diseases and diabetes.According to the World Health Organization (WHO), NCDs are responsible for 74% of all deaths worldwide, and they share four major risk factors: tobacco use, physical inactivity, the harmful use of alcohol and unhealthy diets.These modifiable behaviours increase the risk of metabolic risk factors such as raised blood pressure, increased blood glucose, elevated blood lipids and obesity, which can lead to NCDs.
Choice A is wrong because trauma is not a factor that can lead to many diseases, but rather a result of injuries or accidents that damage the body.Trauma can cause acute or chronic conditions, such as infections, bleeding, fractures, organ failure or post-traumatic stress disorder, but it is not a common cause of NCDs.
Choice C is wrong because congenital means present at birth or inherited.
Congenital diseases are caused by genetic mutations or environmental factors that affect the development of the fetus.
Some examples of congenital diseases are Down syndrome, cystic fibrosis, congenital heart defects and spina bifida.
Congenital diseases are not the greatest contributing factor to many diseases because they are relatively rare and often detected early.
Choice D is wrong because genetics refers to the inherited traits from parents that influence the risk of developing certain diseases.
Genetics can play a role in some NCDs, such as cancers, diabetes and some cardiovascular diseases, but it is not the only or the most important factor.
Genetics interacts with environmental and lifestyle factors to determine the likelihood of developing a disease.
Therefore, genetics alone cannot lead to many diseases.
Correct Answer is C
Explanation
Digoxin is a cardiac glycoside that increases the force of heart contractions (positive inotropy) and decreases the heart rate (negative chronotropy) by inhibiting the sodium-potassium ATPase pump in the cardiac cell membranes and affecting the autonomic tone.This helps to improve the symptoms of heart failure and to control the ventricular rate in atrial fibrillation.
Choice A is wrong because positive chronotropy means increasing the heart rate, which is the opposite of what digoxin does.
Choice B is wrong because negative inotropy means decreasing the force of heart contractions, which is also the opposite of what digoxin does.
Choice D is wrong because positive inotropy and positive chronotropy would both increase the workload of the heart, which is not desirable in heart failure or atrial fibrillation.
Normal ranges for digoxin are 0.5 to 2 ng/mL for heart failure and 0.8 to 2 ng/mL for atrial fibrillation.Digoxin has a narrow therapeutic window and can cause serious side effects if overdosed or underdosed.
