#1
Which of the following is NOT a major electrolyte found in the body?
Chlorine
ExplanationChlorine is not a major electrolyte in the body; the major ones include sodium, potassium, and calcium.
#2
Which condition is characterized by excessive accumulation of fluid in the interstitial spaces?
Hypervolemia
ExplanationHypervolemia is characterized by excessive fluid in the interstitial spaces, leading to swelling and edema.
#3
Which condition is characterized by excessive thirst and urination, often accompanied by dehydration?
Diabetes mellitus
ExplanationDiabetes mellitus is characterized by excessive thirst and urination due to high blood sugar levels, often leading to dehydration.
#4
Which electrolyte imbalance can lead to cardiac arrhythmias and muscle weakness?
Hyperkalemia
ExplanationHyperkalemia, or high potassium levels, can lead to cardiac arrhythmias and muscle weakness.
#5
Which hormone plays a key role in regulating sodium and water balance in the body?
Aldosterone
ExplanationAldosterone plays a key role in regulating sodium and water balance by promoting sodium retention and potassium excretion.
#6
Which acid-base imbalance results from excessive retention of carbon dioxide?
Respiratory acidosis
ExplanationRespiratory acidosis occurs when there's too much carbon dioxide in the blood due to inadequate ventilation.
#7
Which intervention is appropriate for a patient experiencing hypokalemia?
Administering potassium supplements
ExplanationHypokalemia, or low potassium levels, can be treated by administering potassium supplements.
#8
Which acid-base imbalance occurs as a compensatory mechanism for respiratory acidosis?
Compensated respiratory alkalosis
ExplanationCompensated respiratory alkalosis occurs as a compensatory mechanism for respiratory acidosis to maintain pH balance.
#9
Which intervention is appropriate for a patient experiencing hypernatremia?
Restricting sodium intake
ExplanationHypernatremia, or high sodium levels, can be managed by restricting sodium intake.
#10
Which acid-base imbalance is characterized by decreased serum pH and bicarbonate levels due to excess loss of bicarbonate?
Metabolic acidosis
ExplanationMetabolic acidosis involves decreased serum pH and bicarbonate levels due to excess loss of bicarbonate.
#11
Which laboratory finding indicates metabolic acidosis?
Decreased pH, decreased bicarbonate
ExplanationMetabolic acidosis is indicated by a decrease in both pH and bicarbonate levels in the blood.
#12
Which condition is characterized by decreased serum pH, increased serum bicarbonate, and compensatory hypoventilation?
Metabolic acidosis
ExplanationMetabolic acidosis involves decreased serum pH and increased serum bicarbonate levels, leading to compensatory hypoventilation.
#13
Which condition is characterized by increased serum pH, decreased serum bicarbonate, and compensatory hyperventilation?
Metabolic alkalosis
ExplanationMetabolic alkalosis involves increased serum pH, decreased serum bicarbonate, and compensatory hyperventilation to maintain pH balance.
#14
Which condition is characterized by increased serum pH, decreased serum bicarbonate, and compensatory hypoventilation?
Metabolic alkalosis
ExplanationMetabolic alkalosis involves increased serum pH, decreased serum bicarbonate, and compensatory hypoventilation to maintain pH balance.
