A patient comes to the clinic complaining of seasonal rhinitis. What adrenergic agonist will be prescribed for seasonal rhinitis?

A) “Alzheimer disease affects memory but not personality.”
While memory loss is one of the hallmark symptoms of Alzheimer’s disease, the condition also significantly impacts other cognitive functions, including personality and behavior. As the disease progresses, patients often experience changes in mood, behavior, and personality, such as increased irritability, depression, or aggression.

B) “With proper treatment, symptoms of this disease can be arrested.”
Currently, there is no cure for Alzheimer’s disease, and while some treatments (like cholinesterase inhibitors) can help manage symptoms temporarily or slow their progression, the disease itself is not arrestable. The goal of treatment is to manage symptoms and improve quality of life, but it cannot stop the disease from advancing.

C) “The onset of Alzheimer disease is usually between 65 and 75 years.”
While Alzheimer’s disease typically affects older adults, this statement is too narrow. Alzheimer’s disease can begin earlier, sometimes in individuals in their 50s or 60s, particularly in cases of early-onset Alzheimer’s. The average age of onset for most people is around 65, but there is variability.

D) “Alzheimer disease is a chronic, progressive condition.”
Alzheimer’s disease is indeed chronic (lasting for years) and progressive (it worsens over time). It gradually destroys brain cells, leading to a decline in cognitive function, including memory, thinking, and reasoning skills. This is the fundamental nature of the disease

A) Phagocytosis: Phagocytosis refers to the process by which a cell engulfs large particles, such as pathogens or debris, and brings them into the cell. It is not related to the movement of hormones across the cell membrane.
B) Endocytosis: Endocytosis is the process where a cell engulfs substances from the external environment and brings them into the cell. However, this term is typically used when substances like nutrients or larger molecules are taken into the cell, not when hormones are being secreted out of the cell.
C) Pinocytosis: Pinocytosis is a type of endocytosis in which the cell engulfs extracellular fluid and dissolved substances. It is often referred to as "cell drinking" and involves the uptake of fluids, not the secretion of hormones across the membrane.
D) Exocytosis: This is the correct answer. Exocytosis is the process by which substances, such as hormones or neurotransmitters, are transported from inside the cell to the outside by vesicles that fuse with the cell membrane. In the case of hormones, they are synthesized within the cell and then released into the extracellular space via exocytosis, enabling them to reach their target sites.
