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
Explanation
Choice A Reason:
Necrosis is the term used to describe the death of cells or tissues through injury or disease, particularly when it involves severe cell swelling, breakdown of organelles, and release of cellular debris. This process is typically uncontrolled and results from factors such as lack of blood flow (ischemia), toxins, or trauma. In the context of a heart attack, necrosis occurs due to the lack of oxygen and nutrients, leading to cell death and tissue damage.
Choice B Reason:
Apoptosis is a form of programmed cell death that occurs in a controlled and regulated manner. It is a natural process that helps maintain homeostasis by eliminating damaged or unnecessary cells without causing inflammation. Unlike necrosis, apoptosis involves cell shrinkage, chromatin condensation, and DNA fragmentation, but it does not result in the release of cellular debris.
Choice C Reason:
Adaptation refers to the changes that cells undergo in response to stress or adverse conditions to survive and maintain function. These changes can include hypertrophy, hyperplasia, atrophy, and metaplasia. Adaptation is a reversible process and does not involve cell death or the breakdown of cellular components.
Choice D Reason:
Pathologic calcification is the abnormal deposition of calcium salts in tissues. It can occur in areas of necrosis (dystrophic calcification) or in normal tissues due to hypercalcemia (metastatic calcification). While pathologic calcification can be associated with cell injury and death, it is not the primary process described in the scenario of a heart attack leading to cell death with severe swelling and breakdown of organelles.
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.
