Which assessment findings are typical of deep vein thrombosis (DVT) in the lower leg?
Pain and edema in the affected limb.
Muscle paralysis and paresthesia.
Reduced pulses in the foot.
Skin pallor in the area of the thrombosis.
The Correct Answer is A
Choice A rationale:
Pain and edema in the affected limb are typical assessment findings of deep vein thrombosis (DVT) in the lower leg. This is due to the obstruction of blood flow by the thrombus, which leads to swelling and discomfort in the affected limb.
Choice B rationale:
Muscle paralysis and paresthesia are not typical assessment findings of DVT in the lower leg. DVT is more commonly associated with pain and swelling, rather than muscle paralysis or paresthesia.
Choice C rationale:
Reduced pulses in the foot may occur in severe cases of DVT, but it is not one of the primary and typical assessment findings. Pain and edema are more common and reliable indicators of DVT.
Choice D rationale:

Correct Answer is A
Explanation
Choice A rationale:
High LDL (low-density lipoprotein) levels are a well-established risk factor for atherosclerosis. Elevated LDL cholesterol can lead to the deposition of cholesterol in the arterial walls, promoting the development of atherosclerotic plaques. Typically, an LDL level above 130 mg/dL is considered high.
Choice B rationale:
Low LDL levels are generally considered beneficial and are not associated with a higher risk of atherosclerosis. Lower LDL levels can be achieved through lifestyle modifications or medication and are often recommended for cardiovascular health.
Choice C rationale:
High HDL (high-density lipoprotein) levels are associated with a lower risk of atherosclerosis. HDL is considered "good" cholesterol because it helps remove excess cholesterol from the arteries. High HDL levels are typically desirable for cardiovascular health.
Choice D rationale:
Low triglyceride levels are not a primary risk factor for atherosclerosis. Elevated triglyceride levels can be associated with metabolic syndrome and other cardiovascular risk factors, but they are not as directly linked to atherosclerosis as high LDL levels.
Correct Answer is B
Explanation
Choice A rationale:
Chorea is a movement disorder that can be seen in some cases of acute rheumatic fever, but it is not the result of an abnormal immune response to group A streptococcal cell membrane antigens. Chorea is characterized by involuntary, rapid, and irregular movements.
Choice C rationale:
C-reactive protein is a marker of inflammation and can be elevated in acute rheumatic fever, but it is not the primary cause of the condition. Acute rheumatic fever is an autoimmune response to group A streptococcal infection, and M proteins play a significant role in its pathophysiology.
Choice D rationale:
Streptolysin O is a toxin produced by some streptococcal bacteria but is not the primary cause of acute rheumatic fever. It can, however, contribute to the overall inflammatory response in certain cases.
