A nurse is collecting data on a patient who is experiencing hypovolemia. Which of the following findings should the nurse expect?

Peripheral edema

Bradycardia

Cyanosis

Hypotension

Answer and Explanation

The Correct Answer is D

Choice A reason: Peripheral edema is typically associated with ﬂuid overload, not hypovolemia, which is a decreased volume of circulating blood in the body.

Choice B reason: Bradycardia, or a slow heart rate, is not commonly associated with hypovolemia. Tachycardia, or a rapid heart rate, may occur as the body atempts to compensate for the reduced blood volume.

Choice C reason: Cyanosis, which is a bluish discoloration of the skin due to lack of oxygen, is not a direct sign of hypovolemia.

Choice D reason: Hypotension, or low blood pressure, is a common finding in hypovolemia as there is less blood circulating through the body.

Correct Answer is A

Explanation

Choice A reason: Respiratory acidosis is indicated by a pH lower than the normal range (7.35-7.45), combined with a CO2 level higher than the normal range (35-45 mmHg). In this scenario, the pH is 7.33, which is slightly acidic, and the CO2 is 50, which is elevated, suggesting that the lungs are not adequately removing CO2.

Choice B reason: Metabolic acidosis is characterized by a low pH and a low HCO3 level. However, in this case, the HCO3 is normal (22-26 mEq/L), ruling out metabolic acidosis.

Choice C reason: Metabolic alkalosis would present with a high pH and a high HCO3 level. Since the pH is low, metabolic alkalosis is not the correct answer.

Choice D reason: Respiratory alkalosis is characterized by a high pH and a low CO2 level. Given that the pH is low and the CO2 is high, respiratory alkalosis is not the condition indicated by these ABG results.

A. Administer sodium bicarbonate to the patient. B. Provide a paper bag for the patient to breathe into. C. Monitor the patient's head being between their knees. D. Administer acetazolamide to the patient.

Correct Answer is B

Explanation

Choice A reason: Administering sodium bicarbonate is not indicated for respiratory alkalosis as it is an alkalinizing agent and could worsen the condition.

Choice B reason: Breathing into a paper bag can help to rebreathe CO2, which can help correct the pH in cases of hyperventilation-induced respiratory alkalosis.

Choice C reason: Having the patient's head between their knees is not a standard intervention for respiratory alkalosis and could be uncomfortable or unsafe for the patient.

Choice D reason: Acetazolamide is a diuretic that can cause metabolic acidosis to compensate for respiratory alkalosis, but it is not typically used for acute management of hyperventilation.
