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 B
Explanation
Choice A: Decreased Respirations
Decreased respirations, or a slower breathing rate, are not typically associated with acute stress. In fact, acute stress often leads to an increase in respiratory rate as part of the body’s “fight or flight” response. This response is mediated by the autonomic nervous system, which prepares the body to respond to a perceived threat by increasing heart rate, respiratory rate, and blood pressure.
Choice B: Tachycardia
Tachycardia, or an increased heart rate, is a common indicator of acute stress. When an individual experiences acute stress, the body releases stress hormones such as adrenaline and cortisol. These hormones stimulate the heart to beat faster, providing more oxygen and nutrients to the muscles and brain to prepare for a rapid response to the stressor. Tachycardia is a hallmark of the acute stress response and can be easily measured by checking the pulse.
Choice C: Hair Loss
Hair loss is generally associated with chronic stress rather than acute stress. Chronic stress can lead to conditions such as telogen effluvium, where hair follicles enter a resting phase and hair falls out more easily. However, this process takes time and is not an immediate response to acute stress. Therefore, hair loss is not a reliable indicator of acute stress.
Choice D: Pupil Constriction
Pupil constriction, or miosis, is not typically associated with acute stress. In fact, acute stress usually causes pupil dilation (mydriasis) as part of the “fight or flight” response. Dilated pupils allow more light to enter the eyes, improving vision and awareness of the surroundings. Pupil constriction is more commonly associated with relaxation or the body’s “rest and digest” state, mediated by the parasympathetic nervous system.
Correct Answer is D
Explanation
Choice A: Atrophy
Atrophy refers to the reduction in size or wasting away of an organ or tissue due to a decrease in cell size or number. This can occur due to various reasons such as disuse, lack of nutrition, or loss of nerve supply. While atrophy involves the shrinkage of cells, it does not directly result in cellular death. Instead, it is a form of cellular adaptation to adverse conditions.
Choice B: Proliferation
Proliferation is the process by which cells grow and divide to produce more cells. This process is essential for growth, development, and tissue repair. Proliferation leads to an increase in the number of cells and is the opposite of cellular death. It is a tightly regulated process that ensures the maintenance and regeneration of tissues.
Choice C: Mutation
Mutation refers to changes in the DNA sequence of a cell. These changes can occur due to errors during DNA replication, exposure to radiation, or chemical mutagens. While mutations can lead to various outcomes, including cancer, they do not directly cause cellular death. Instead, mutations can alter the function of genes and proteins, potentially leading to uncontrolled cell growth or other cellular dysfunctions.
Choice D: Death
Apoptosis is a form of programmed cell death that occurs in multicellular organisms. It is a highly regulated process that allows the body to remove damaged or unnecessary cells without causing harm to surrounding tissues. Apoptosis involves a series of biochemical events leading to characteristic cell changes and eventual death. This process is crucial for maintaining cellular homeostasis and preventing the development of diseases such as cancer.
