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 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
Correct Answer is C
Explanation
Urecholine is the brand name of bethanechol, a drug that belongs to the class of cholinergics, genitourinary.
Choice A is wrong because adrenergic drugs are those that activate the sympathetic nervous system, which is responsible for the fight-or-flight response.Adrenergic drugs can cause relaxation of the bladder and urinary retention, not contraction and emptying.
Choice B is wrong because anticholinergic drugs are those that block the action of acetylcholine, a neurotransmitter that mediates the parasympathetic nervous system, which is responsible for the rest-and-digest response.Anticholinergic drugs can also cause relaxation of the bladder and urinary retention, not contraction and emptying.
Choice D is wrong because adrenergic blockers are those that inhibit the action of adrenergic receptors, which are activated by adrenergic drugs or by the natural neurotransmitters norepinephrine and epinephrine.Adrenergic blockers can have various effects on the bladder depending on the type and location of the receptors they block, but they are not used to treat urinary retention.
