A.

True

B.

False

Answer and Explanation

The Correct Answer is B

Acute gastritis is indeed a transient inflammation of the gastric mucosa and often results from local irritants like aspirin, NSAIDs, alcohol, caffeine, and contaminated food. It is typically self-limiting and resolves once the irritant is removed. However, the statement is incorrect in describing it as "very serious" in most cases. While complications can occur, acute gastritis is usually mild and not considered very serious unless left untreated.

Correct Answer is A

Explanation

The adrenal cortex is vital for life because it produces key hormones such as cortisol, aldosterone, and androgens. Cortisol helps regulate metabolism, stress responses, and immune function. Aldosterone maintains sodium and potassium balance, crucial for blood pressure and fluid regulation. Without these hormones, the body cannot sustain essential physiological processes.

Correct Answer is A

Explanation

A. Brain, blood, cerebrospinal fluid (CSF): These are the three main components within the cranial vault as described by the Monro-Kellie doctrine. The total volume of these components remains constant, and any increase in one must be offset by a decrease in another to prevent elevated ICP.

B. Cerebrospinal fluid (CSF), blood, oxygen: While CSF and blood are intracranial components, oxygen is not a physical substance occupying volume in the cranial cavity. It is transported within the blood and does not contribute to changes in ICP in terms of physical space.

C. Brain, cerebrospinal fluid (CSF), air: Air is not a normal component of the cranial cavity. The presence of air would indicate pathology, such as a skull fracture with pneumocephalus, which is abnormal and can contribute to increased ICP but is not a standard component.

D. Brain, blood, lymphatic fluid: While the brain and blood are correct components, the central nervous system, including the brain, does not have a conventional lymphatic system like other parts of the body. Waste products are primarily cleared by the glymphatic system, which utilizes CSF, rather than traditional lymphatic fluid.
