A nurse is reviewing the laboratory results of a client who is taking a loop diuretic and notes the client’s potassium level is 3.0 mEq/L. Which of the following physiological responses should the nurse expect related to the client’s hypokalemia?

a. Magnesium 1.9 mg: This magnesium level is within the expected reference range (1.3-2.1 mEq/L).

b. Chloride 99 mEq/L: This chloride level is within the expected reference range (98-106 mEq/L).

c. Sodium 126 mEq/L: A sodium level of 126 mEq/L is significantly below the normal range (135-145 mEq/L), indicating hyponatremia, which can have serious consequences and requires prompt attention.

d. Potassium 3.6 mEq/L: This potassium level is within the expected reference range (3.5-5.0 mEq/L).

a. Low BP and low pulse rate: In hypovolemic shock, there is a decrease in blood volume,

leading to low blood pressure. However, the body compensates by increasing the heart rate to maintain perfusion to vital organs.

b. Low BP and high pulse rate: This is indicative of hypovolemic shock. The low blood pressure results from decreased blood volume, while the high pulse rate is a compensatory mechanism to maintain cardiac output.

c. High BP and low pulse rate: This combination is not typical of hypovolemic shock. High blood pressure is not expected in the presence of decreased blood volume.

d. High BP and high pulse rate: While a high pulse rate is expected in hypovolemic shock, high blood pressure is not a characteristic finding.
