The adrenal cortex function is essential for life. (True or False)
True
False
The Correct Answer is A
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 D
Explanation
A. Azotemia: Azotemia, or elevated blood urea nitrogen (BUN) and creatinine levels, is a common feature of glomerulonephritis due to reduced kidney filtration capacity and accumulation of nitrogenous wastes in the blood.
B. Hematuria with red cell casts: Hematuria with red blood cell casts is a classic hallmark of glomerulonephritis, indicating glomerular bleeding and inflammation. These casts are formed in the nephron and reflect active glomerular injury.
C. Oliguria and hypertension: Both are characteristic findings in glomerulonephritis. Oliguria results from impaired filtration, while hypertension develops due to fluid retention and activation of the renin-angiotensin-aldosterone system.
D. An increased glomerular filtration rate (GFR) of >100: Glomerulonephritis typically leads to a decreased GFR, not an increase. Inflammation and damage to the glomeruli impair the kidneys' ability to filter blood effectively, resulting in reduced GFR and waste accumulation.
Correct Answer is B
Explanation
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.
