The patient who was admitted after vomiting for 3 days would show an abnormally low blood pressure because of a fluid shift from:

intracellular to the extracellular.

interstitial to intravascular.

interstitial to the intracellular.

intravascular to the interstitial.

Answer and Explanation

The Correct Answer is D

Choice A reason: Intracellular to the extracellular fluid shift is not the cause of low blood pressure in this case. This fluid shift occurs when the cells lose water due to osmosis, such as in dehydration or hypernatremia.

Choice B reason: Interstitial to intravascular fluid shift is not the cause of low blood pressure in this case. This fluid shift occurs when the fluid moves from the tissue spaces to the blood vessels, such as in hypovolemia or hypotonic fluid administration.

Choice C reason: Interstitial to the intracellular fluid shift is not the cause of low blood pressure in this case. This fluid shift occurs when the fluid moves from the tissue spaces to the cells, such as in overhydration or hyponatremia.

Choice D reason: Intravascular to the interstitial fluid shift is the cause of low blood pressure in this case. This fluid shift occurs when the fluid moves from the blood vessels to the tissue spaces, such as in edema, inflammation, or increased capillary permeability. This reduces the blood volume and lowers the blood pressure.

Correct Answer is A

Explanation

Choice A reason: This is correct because 3.5 to 5.0 mEq/L is the normal range of serum potassium level in adults. Potassium is an electrolyte that is important for nerve and muscle function, as well as acid-base balance.

Choice B reason: This is incorrect because 8.5 to 10.5 mg/dL is the normal range of serum calcium level in adults, not potassium. Calcium is an electrolyte that is involved in bone health, muscle contraction, and blood clotting.

Choice C reason: This is incorrect because 135 to 145 mEq/L is the normal range of serum sodium level in adults, not potassium. Sodium is an electrolyte that is essential for fluid balance, nerve transmission, and muscle contraction.

Choice D reason: This is incorrect because 1.8 to 2.6 mEq/L is the normal range of serum magnesium level in adults, not potassium. Magnesium is an electrolyte that is important for muscle and nerve function, as well as enzyme activity.

A. Metabolic alkalosis B. Metabolic acidosis C. Respiratory alkalosis D. Respiratory acidosis

Correct Answer is A

Explanation

Choice A reason: This is correct because metabolic alkalosis is characterized by a high pH and a high HCO3-. The client's pH and HCO3- are both high, indicating a metabolic disorder. The condition is uncompensated because the PaCO2 is normal, meaning the respiratory system is not compensating for the metabolic alkalosis.

Choice B reason: This is incorrect because metabolic acidosis is characterized by a low pH and a low HCO3-. The client's pH and HCO3- are both high, indicating alkalosis, not acidosis.

Choice C reason: This is incorrect because respiratory alkalosis is characterized by a high pH and a low PaCO2. The client's pH is high, but PaCO2 is normal, indicating a metabolic problem, not a respiratory one.

Choice D reason: This is incorrect because respiratory acidosis is characterized by a low pH and a high PaCO2. The client's pH is high, and PaCO2 is normal, indicating a metabolic problem, not a respiratory one.
