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
a. Hemiparesis: Both
- Higher fatality rate: Hemorrhagic CVA
- Rupture of vessel: Hemorrhagic CVA
- Loss of blood flow: Ischemic CVA
- Most common: Ischemic CVA
- Altered sensorium: Both
Rationale: A cerebrovascular accident (CVA), or stroke, is a sudden interruption of blood supply to the brain, resulting in neurological damage. There are two main types of stroke: ischemic and hemorrhagic. Ischemic stroke occurs when a blood clot or plaque blocks an artery that supplies blood to the brain, causing tissue death due to lack of oxygen and nutrients. Hemorrhagic stroke occurs when a blood vessel in the brain ruptures, causing bleeding into the brain tissue or the surrounding space. Both types of stroke can cause hemiparesis (weakness on one side of the body), altered sensorium (changes in consciousness, alertness, or orientation), and other neurological deficits depending on the location and extent of the damage. However, hemorrhagic stroke has a higher fatality rate than ischemic stroke because of the increased risk of intracranial pressure, cerebral edema, and brain herniation. Ischemic stroke is more common than hemorrhagic stroke, accounting for about 87% of all strokes.
Correct Answer is A
Explanation
Respiratory alkalosis is a condition where the blood's pH is elevated due to excessive removal of CO2 from the body. This can occur when the breathing rate is too fast or deep, such as in response to hypoxia, anxiety, fever, or lung disease. When CO2 is removed from the blood, less H2CO3 is formed, which raises the blood's pH by decreasing the concentration of H+ and HCO3- . A normal blood pH is between 7.35 and 7.45, and a normal partial pressure of arterial carbon dioxide (PaCO2) is between 35- and 45 mm Hg. Therefore, a patient with respiratory alkalosis would have a higher-than-normal pH and a lower-than-normal PaCO2.
