Which condition is characterized by an excess of sodium in the blood?

Hypernatremia

Explanation

Excess sodium in blood.

Which of the following is a common cause of hypokalemia?

Diarrhea

Explanation

Loss of potassium due to diarrhea.

Which hormone is primarily responsible for regulating potassium levels in the body?

Aldosterone

Explanation

Aldosterone regulates potassium levels.

Which of the following is a symptom of hypernatremia?

Confusion

Explanation

Confusion due to excess sodium.

Which electrolyte imbalance is commonly associated with muscle cramps and weakness?

Hypokalemia

Explanation

Low potassium levels causing cramps and weakness.

Which of the following conditions is a risk factor for developing hyponatremia?

Heart failure

Explanation

Heart failure predisposes to hyponatremia.

Which condition is characterized by excessive thirst and polyuria due to dilutional hyponatremia?

Syndrome of inappropriate antidiuretic hormone (SIADH) secretion

Explanation

SIADH leads to diluted blood sodium, causing thirst and polyuria.

What is the typical serum sodium level in hyponatremia?

Below 135 mEq/L

Explanation

Serum sodium level below 135 mEq/L.

Which electrolyte abnormality can cause cardiac arrhythmias?

Hyperkalemia

Explanation

High potassium levels leading to cardiac arrhythmias.

#10

Which electrolyte imbalance can lead to muscle weakness and cardiac dysrhythmias?

Hyperkalemia

Explanation

High potassium levels causing weakness and dysrhythmias.

#11

What is the primary cause of hyperkalemia in patients with chronic kidney disease?

Decreased urinary potassium excretion

Explanation

Kidneys fail to excrete potassium properly.

#12

Which hormone regulates calcium levels in the blood?

Parathyroid hormone (PTH)

Explanation

PTH regulates blood calcium.

#13

What is the primary cause of hypocalcemia in patients with chronic kidney disease?

Decreased parathyroid hormone (PTH) production

Explanation

Reduced PTH production leads to low calcium.

#14

Which of the following conditions is associated with respiratory alkalosis?

Hyperventilation

Explanation

Excessive breathing leads to respiratory alkalosis.

#15

Which condition is associated with metabolic alkalosis?

Vomiting

Explanation

Vomiting leads to loss of gastric acid, causing alkalosis.

#16

Which of the following conditions is associated with metabolic acidosis?

Chronic obstructive pulmonary disease (COPD)

Explanation

COPD leads to metabolic acidosis.

#17

Which electrolyte imbalance is commonly seen in patients with Addison's disease?

Hyperkalemia

Explanation

Addison's disease causes high potassium levels.

#18

Which electrolyte imbalance can lead to a prolonged QT interval on an electrocardiogram (ECG)?

Hypokalemia

Explanation

Low potassium levels causing QT prolongation.

#19

Which electrolyte imbalance is commonly associated with prolonged use of loop diuretics?

Hypokalemia

Explanation

Loop diuretics cause potassium loss.
