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
PT stands for prothrombin time, which is a measure of how long it takes the blood to clot. INR stands for international normalized ratio, which is a standardized way of reporting the PT result. Warfarin is a blood thinner that works by slowing down the clotting process.Therefore, people who take warfarin need to have their PT/INR monitored regularly to make sure they are getting the right dose and not bleeding too much or too little.
Choice A is wrong because PTT stands for partial thromboplastin time, which is another measure of blood clotting that is not affected by warfarin.PTT is used to monitor heparin, another type of blood thinner.
Choice C is wrong because CBC stands for complete blood count, which is a test that measures the number and types of cells in the blood, such as red blood cells, white blood cells and platelets.CBC can show if there is anemia, infection or bleeding, but it does not measure the effect of warfarin on clotting.
Choice D is wrong because LFTs stand for liver function tests, which are a group of tests that check how well the liver is working.
LFTs can show if there is liver damage or disease, which can affect how warfarin is metabolized and cleared from the body.However, LFTs do not directly measure the effect of warfarin on clotting.
The normal range for PT/INR varies depending on the laboratory and the reason for taking warfarin.
Generally, the normal range for PT is 10 to 13 seconds, and the normal range for INR is 1.1 or below for healthy people.For people taking warfarin, the target INR range depends on their condition and risk factors, but it is usually between 2.0 and 3.0.
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.
