#1
Which electrolyte imbalance can lead to muscle weakness and cardiac arrhythmias?
Hypokalemia
ExplanationLow potassium levels affect muscle and heart function.
#2
Which of the following is a clinical manifestation of hypercalcemia?
Renal stones
ExplanationExcess calcium can precipitate as stones in the kidneys.
#3
Which electrolyte imbalance can lead to neuromuscular excitability, such as tetany and seizures?
Hypocalcemia
ExplanationLow calcium levels cause hyperexcitability of nerves and muscles.
#4
Which of the following is a common cause of hyperkalemia?
Addison's disease
ExplanationAdrenal insufficiency can lead to potassium retention.
#5
Which electrolyte imbalance is commonly associated with flattened T waves on an ECG?
Hypokalemia
ExplanationLow potassium levels affect cardiac depolarization.
#6
Which of the following is a clinical manifestation of hypomagnesemia?
Hyporeflexia
ExplanationLow magnesium levels can lead to decreased reflexes.
#7
Which electrolyte imbalance can lead to confusion, seizures, and coma?
Hypernatremia
ExplanationExcess sodium levels affect brain function.
#8
Which of the following is a clinical manifestation of hypermagnesemia?
Hyperreflexia
ExplanationExcess magnesium levels can lead to exaggerated reflexes.
#9
Which electrolyte imbalance is commonly associated with muscle weakness, cardiac arrhythmias, and digitalis toxicity?
Hypokalemia
ExplanationLow potassium levels affect muscle and heart function.
#10
Which of the following is a clinical manifestation of hypophosphatemia?
Rhabdomyolysis
ExplanationLow phosphate levels can lead to muscle breakdown.
#11
What is the primary cause of metabolic acidosis?
Excessive loss of bicarbonate
ExplanationLoss of bicarbonate leads to acid accumulation in the body.
#12
Which electrolyte imbalance is associated with Trousseau's sign and Chvostek's sign?
Hypocalcemia
ExplanationLow calcium levels trigger neuromuscular irritability.
#13
What is the primary manifestation of respiratory alkalosis?
Hyperventilation
ExplanationExcessive breathing reduces carbon dioxide levels in blood.
#14
Which electrolyte imbalance is commonly associated with prolonged QT interval on an ECG?
Hypokalemia
ExplanationLow potassium levels affect cardiac repolarization.
#15
What is the primary cause of respiratory acidosis?
Hypoventilation
ExplanationInadequate breathing leads to carbon dioxide buildup.
#16
Which electrolyte imbalance is commonly associated with muscle weakness and cardiac dysrhythmias?
Hypokalemia
ExplanationLow potassium levels affect muscle and heart function.
#17
What is the primary cause of respiratory alkalosis?
Hyperventilation
ExplanationExcessive breathing reduces carbon dioxide levels in blood.
#18
Which of the following is a common cause of hyponatremia in hospitalized patients?
Syndrome of inappropriate antidiuretic hormone secretion (SIADH)
ExplanationExcessive ADH leads to water retention and dilution of sodium levels.
#19
What is the primary cause of metabolic alkalosis?
Excessive vomiting
ExplanationLoss of stomach acid through vomiting leads to alkalosis.
#20
What is the primary cause of hypernatremia in patients with impaired thirst mechanism?
Insufficient water intake
ExplanationNot drinking enough water leads to sodium concentration in the blood.
