What are the most common complications of myocardial infarction? (Select all that apply)
(Select All that Apply.)
Percutaneous coronary intervention
Sudden death
Dysrhythmias
Congestive hearts failure
Correct Answer : B,C,D
A. Percutaneous coronary intervention: Percutaneous coronary intervention (PCI) is a treatment used to open blocked coronary arteries during a myocardial infarction but is not a complication of the event itself. It is a therapeutic procedure aimed at restoring blood flow and is not a direct consequence of myocardial infarction.
B. Sudden death: Sudden death can occur as a complication of myocardial infarction due to severe dysrhythmias or cardiac arrest resulting from electrical instability in the heart. This complication is critical and can occur shortly after the onset of an MI or during recovery.
C. Dysrhythmias: Dysrhythmias are common complications following myocardial infarction, often arising from ischemic damage to the heart muscle, which disrupts the normal electrical conduction pathways. These irregular heartbeats can range from benign to life-threatening.
D. Congestive heart failure: Congestive heart failure can develop as a complication of myocardial infarction due to the loss of functional cardiac muscle, resulting in decreased cardiac output and the heart's inability to pump effectively. This complication can develop acutely or progressively over time following an MI.

Correct Answer is A
Explanation
A. Actually, people who have the latent form of the disease won't be sick and can't spread it either: This response is accurate because individuals with latent tuberculosis infection (LTBI) do not exhibit symptoms and are not infectious. They carry the bacteria in their body, but it remains dormant and does not spread to others. Only those with active tuberculosis disease are capable of transmitting the infection through respiratory droplets.
B. Many people do manage to fight off the infection, but you are right: they can still spread it by coughing or sneezing: This statement is misleading because it implies that individuals with LTBI can spread the disease, which is not the case. Only those with active TB are contagious.
C. There isn't any real risk of them spreading it, but we would like to vaccinate everyone who's had any contact with it in the past: This response downplays the importance of understanding the difference between latent and active TB and could create confusion. Vaccination for tuberculosis (BCG vaccine) is not routinely given in the United States, and exposure alone does not necessitate vaccination.
D. If someone has been previously exposed to tuberculosis, they are particularly infectious because they are often unaware of the disease: This statement is incorrect, as individuals who have been exposed but have LTBI are not infectious. It is only those with active TB who pose a risk of spreading the infection.
Correct Answer is C
Explanation
A. Triglycerides: Elevated triglyceride levels are associated with an increased risk of atherosclerosis and cardiovascular disease. High triglycerides can contribute to the buildup of plaque in the arteries, leading to a higher risk of heart disease and complications such as heart attacks or strokes.
B. Very low density lipoproteins (VLDLs): Elevated VLDL levels are considered harmful and are linked to a higher risk of atherosclerosis. VLDLs contribute to the accumulation of triglycerides and promote the development of plaque in the arteries, which can significantly increase cardiovascular risk over time.
C. High density lipoproteins (HDLs): Elevated HDL levels are considered protective against the development of atherosclerosis. HDLs help transport cholesterol away from the arteries and back to the liver for excretion, which not only reduces the risk of plaque buildup but also lowers the likelihood of heart disease and enhances overall cardiovascular health.
D. Low density lipoproteins (LDLs): Elevated LDL levels are known to be a major risk factor for atherosclerosis. LDL cholesterol can contribute to the formation of plaques in the arteries, increasing the risk of heart disease and stroke, and it is important to manage LDL levels for better cardiovascular health.
