4T0X1 CDC's URE Questions (2 of 3)
with Complete Solutions
How is bicarbonate used to assess the body’s acid-base balance?
✔✔Bicarbonate levels indicate whether the body is in a state of metabolic acidosis or alkalosis
What is the relationship between sodium and potassium in maintaining cellular function?
✔✔Sodium and potassium work together to maintain the electrical gradients across cell
membranes, essential for nerve and muscle function
What does an elevated blood urea nitrogen (BUN) level indicate?
✔✔It may suggest kidney dysfunction or dehydration
What is the normal pH range for arterial blood?
✔✔7.35-7.45
What condition can result from an imbalance in the sodium-potassium pump?
✔✔Cellular dysfunction, which may lead to issues such as muscle weakness, arrhythmias, or
nerve conduction problems
1
,What are the causes of metabolic acidosis?
✔✔Diabetic ketoacidosis, renal failure, and severe diarrhea
What is the main treatment approach for hypomagnesemia (low magnesium levels)?
✔✔Magnesium supplementation, either orally or intravenously, depending on severity
What is the relationship between sodium levels and water balance in the body?
✔✔Sodium levels help control the movement of water in and out of cells and tissues, influencing
overall fluid balance
What is the normal range for sodium levels in the blood?
✔✔135-145 mEq/L
What is the primary function of sodium in the body?
✔✔To regulate fluid balance and maintain normal cell function
What condition is associated with low sodium levels (hyponatremia)?
2
,✔✔It can lead to confusion, seizures, and in severe cases, coma
What is the role of potassium in the body?
✔✔To maintain proper heart and muscle function
What is the anion gap and why is it important?
✔✔It helps assess the acid-base balance in the body, particularly in cases of metabolic acidosis
What does an elevated anion gap typically indicate?
✔✔It can suggest the presence of metabolic acidosis due to conditions like diabetic ketoacidosis
or renal failure
What is the normal anion gap range?
✔✔8-12 mEq/L
What is a common cause of hypernatremia (high sodium levels)?
✔✔Dehydration or excessive salt intake
3
, What electrolyte imbalance is commonly seen with prolonged vomiting or diarrhea?
✔✔Hypokalemia (low potassium levels)
What is the main treatment for hyperkalemia (high potassium levels)?
✔✔Administering medications like calcium gluconate, sodium bicarbonate, or insulin to lower
potassium levels
What are the symptoms of hypocalcemia (low calcium levels)?
✔✔Muscle cramps, tingling, and in severe cases, seizures
What is the role of chloride in the body?
✔✔To help maintain fluid balance and regulate blood volume
The best term that describes the water found within cells is ✔✔intracellular water
an example of calculated supplemental data is ✔✔the anion gap
