#1
Which condition is characterized by an excess of sodium in the blood?
Hypernatremia
ExplanationExcess sodium in blood.
#2
Which of the following is a common cause of hypokalemia?
Diarrhea
ExplanationLoss of potassium due to diarrhea.
#3
Which hormone is primarily responsible for regulating potassium levels in the body?
Aldosterone
ExplanationAldosterone regulates potassium levels.
#4
Which of the following is a symptom of hypernatremia?
Confusion
ExplanationConfusion due to excess sodium.
#5
Which electrolyte imbalance is commonly associated with muscle cramps and weakness?
Hypokalemia
ExplanationLow potassium levels causing cramps and weakness.
#6
Which of the following conditions is a risk factor for developing hyponatremia?
Heart failure
ExplanationHeart failure predisposes to hyponatremia.
#7
Which condition is characterized by excessive thirst and polyuria due to dilutional hyponatremia?
Syndrome of inappropriate antidiuretic hormone (SIADH) secretion
ExplanationSIADH leads to diluted blood sodium, causing thirst and polyuria.
#8
Which electrolyte imbalance is commonly associated with prolonged vomiting or nasogastric suctioning?
Hypokalemia
ExplanationLoss of potassium due to vomiting or suctioning.
#9
Which of the following is a common symptom of hyperkalemia?
Muscle weakness
ExplanationWeakness due to high potassium levels.
#10
What is the primary cause of hypernatremia in elderly patients?
Dehydration
ExplanationElderly patients often become dehydrated.
#11
What is the typical serum sodium level in hyponatremia?
Below 135 mEq/L
ExplanationSerum sodium level below 135 mEq/L.
#12
Which electrolyte abnormality can cause cardiac arrhythmias?
Hyperkalemia
ExplanationHigh potassium levels leading to cardiac arrhythmias.
#13
Which electrolyte imbalance can lead to muscle weakness and cardiac dysrhythmias?
Hyperkalemia
ExplanationHigh potassium levels causing weakness and dysrhythmias.
#14
What is the primary cause of hyperkalemia in patients with chronic kidney disease?
Decreased urinary potassium excretion
ExplanationKidneys fail to excrete potassium properly.
#15
Which hormone regulates calcium levels in the blood?
Parathyroid hormone (PTH)
ExplanationPTH regulates blood calcium.
#16
What is the primary cause of hypocalcemia in patients with chronic kidney disease?
Decreased parathyroid hormone (PTH) production
ExplanationReduced PTH production leads to low calcium.
#17
Which of the following conditions is associated with respiratory alkalosis?
Hyperventilation
ExplanationExcessive breathing leads to respiratory alkalosis.
#18
What is the primary treatment for hypercalcemia?
Calcitonin administration
ExplanationCalcitonin is used to lower blood calcium levels.
#19
Which condition is associated with respiratory acidosis?
Cystic fibrosis
ExplanationCystic fibrosis leads to respiratory acidosis.
#20
What is the primary treatment for hypocalcemia caused by hypoparathyroidism?
Calcium supplements
ExplanationSupplemental calcium is needed for low blood calcium due to hypoparathyroidism.
#21
Which condition is associated with metabolic alkalosis?
Vomiting
ExplanationVomiting leads to loss of gastric acid, causing alkalosis.
#22
Which of the following conditions is associated with metabolic acidosis?
Chronic obstructive pulmonary disease (COPD)
ExplanationCOPD leads to metabolic acidosis.
#23
Which electrolyte imbalance is commonly seen in patients with Addison's disease?
Hyperkalemia
ExplanationAddison's disease causes high potassium levels.
#24
Which electrolyte imbalance can lead to a prolonged QT interval on an electrocardiogram (ECG)?
Hypokalemia
ExplanationLow potassium levels causing QT prolongation.
#25
Which electrolyte imbalance is commonly associated with prolonged use of loop diuretics?
Hypokalemia
ExplanationLoop diuretics cause potassium loss.
