A patient has been exposed to human immunodeficiency virus (HIV) but is not yet demonstrating signs of this disease. This stage of illness is called the ______ stage.
Prodromal
Remission
Exacerbation
Latent
The Correct Answer is D
Choice A Reason:
The prodromal stage refers to the period during which early symptoms of a disease appear but are not yet specific or severe. This stage is often associated with infectious diseases where initial symptoms like fever, malaise, and fatigue occur before more specific symptoms develop. In the context of HIV, the prodromal stage would not be applicable as it refers to the early symptomatic phase rather than a period without symptoms.
Choice B Reason:
Remission is a term used to describe a period during which the symptoms of a disease are reduced or disappear. This term is commonly used in the context of chronic diseases such as cancer or autoimmune disorders. For HIV, remission would imply a reduction in viral load and symptoms due to effective treatment, but it does not describe the asymptomatic phase following initial exposure.
Choice C Reason:
Exacerbation refers to the worsening or flare-up of symptoms in a chronic disease. This term is often used in conditions like asthma or multiple sclerosis where symptoms can become more severe periodically. In the context of HIV, exacerbation would describe periods where symptoms become more pronounced, not the asymptomatic phase after initial exposure.
Choice D Reason:
The latent stage, also known as the clinical latency stage or asymptomatic HIV infection, is the period after initial HIV exposure when the virus is present in the body but not causing any symptoms. During this stage, HIV continues to replicate at low levels, and the individual may not feel sick or show any signs of the disease. This stage can last for several years, especially with effective antiretroviral therapy.

Correct Answer is ["A","B","C","E"]
Explanation
Choice A Reason:
Chronic stress can significantly impact mental health, leading to conditions such as depression. The persistent activation of the stress response system, particularly the release of cortisol, can alter brain function and structure, contributing to mood disorders. Studies have shown that prolonged exposure to stress hormones can lead to changes in the brain that are associated with depression.
Choice B Reason:
Impaired cognitive function is another consequence of chronic stress. Elevated levels of cortisol over an extended period can damage the hippocampus, a region of the brain involved in memory and learning. This can result in difficulties with concentration, memory, and decision-making. Chronic stress has been linked to cognitive decline and an increased risk of neurodegenerative diseases.
Choice C Reason:
Chronic stress can also affect the immune system, leading to autoimmune diseases. The continuous activation of the stress response can cause immune dysregulation, where the body’s immune system mistakenly attacks its own tissues. This can result in conditions such as rheumatoid arthritis, lupus, and other autoimmune disorders.
Choice D Reason:
Overactive immune function is not typically associated with chronic stress. Instead, chronic stress often leads to a weakened immune response, making the body more susceptible to infections and illnesses. Therefore, this choice is incorrect.
Choice E Reason:
Cardiovascular disease is a well-documented consequence of chronic stress. The persistent release of stress hormones like adrenaline and cortisol can lead to increased blood pressure, heart rate, and the formation of artery-clogging deposits. These changes can increase the risk of heart disease, heart attacks, and strokes.
Correct Answer is B
Explanation
Choice A: Beta 2 Agonist Decreases Blood Pressure
Beta 2 agonists primarily cause bronchodilation and vasodilation, which can lead to a decrease in blood pressure. However, this is not their primary function, and they are more commonly associated with the relaxation of smooth muscles in the airways.
Choice B: Beta 1 Agonist Increases Blood Pressure
Beta 1 receptors are primarily located in the heart. Activation of these receptors increases heart rate and contractility, which in turn increases cardiac output and blood pressure. Therefore, beta 1 agonists are known to increase blood pressure.
Choice C: Beta 2 Agonist Reduces Blood Pressure
Similar to choice A, beta 2 agonists can cause vasodilation, which may reduce blood pressure. However, this is not their primary therapeutic use, and they are mainly used for their bronchodilatory effects.
Choice D: Beta 1 Agonist Reduces Blood Pressure
Beta 1 agonists increase heart rate and contractility, leading to an increase in blood pressure. Therefore, this statement is incorrect as beta 1 agonists do not reduce blood pressure.
