What is a clinical manifestation of dehydration?
Peripheral edema
Oliguria
Elevated blood pressure
Dyspnea
The Correct Answer is B
Oliguria is a condition where the urine output is less than normal, usually less than 500 mL per day in adults. Oliguria can be a sign of dehydration, which occurs when the body loses more water than it takes in. Dehydration can cause various symptoms such as thirst, dry mouth, headache, dizziness, fatigue, and confusion.
Dehydration can also affect kidney function and lead to electrolyte imbalances and acid-base disorders.

Explanation
This condition is an infection of the inner lining of the heart chambers and valves, which can cause vegetation to form on the valve surfaces. Vegetations are masses of microorganisms, inflammatory cells, and fibrin that adhere to the valve leaflets and can interfere with their function. The symptoms of endocarditis may include fatigue, fever, night sweats, chills, weight loss, or heart murmur.
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.
