Which disease can vitamin B12 deficiency be attributed to?

Diabetes

Obesity

Alcoholism

Hypertension

Answer and Explanation

The Correct Answer is C

Vitamin B12 is a water-soluble vitamin that is involved in the production of red blood cells, DNA synthesis, and nerve function. Vitamin B12 deficiency can cause anemia, neurological problems, and cognitive impairment. Vitamin B12 deficiency can be attributed to alcoholism because alcohol interferes with the absorption and metabolism of vitamin B12 in the stomach and liver. Alcohol also damages the lining of the intestines, where vitamin B12 is absorbed from food sources.

Correct Answer is B

Explanation

ESRD is a condition in which the kidneys lose their ability to filter waste and fluid from the blood, resulting in a buildup of toxins and fluid in the body. ESRD can cause symptoms such as lethargy, oliguria (reduced urine output), and itchy and dry skin due to uremia (high levels of urea in the blood). ESRD can also cause anemia (low levels of red blood cells), which can explain the decrease in hemoglobin and hematocrit. ESRD can be caused by chronic conditions such as hypertension, diabetes, and coronary artery disease, which damage the kidneys over time.

A. Activation of platelets B. Activation of coagulation mediators C. Activation of the renin-angiotensin system D. Activation of rapid cell proliferation

Correct Answer is C

Explanation

The renin-angiotensin system (RAS) is a hormonal system that regulates blood pressure and fluid balance. When blood pressure is low, the kidneys secrete renin, which converts angiotensinogen into angiotensin I, which is then converted into angiotensin II by angiotensin-converting enzyme (ACE). Angiotensin II is a potent vasoconstrictor that narrows blood vessels and increases blood pressure. It also stimulates the release of aldosterone, which increases sodium and water retention and further raises blood pressure. When the RAS is overactivated, it can lead to a hypertensive crisis, which is a severe elevation of blood pressure that can damage organs and cause stroke, heart attack, or kidney failure.
