Fluid and Electrolytes ATI Questions

Question 1 of 5

A nurse sees a variety of patients in the community health clinic. Which of the following patients would be at the greatest risk of dehydration?

Correct Answer: B

Rationale: Infants are particularly vulnerable to dehydration due to diarrhea, as they have a higher fluid turnover and less reserve.

Question 2 of 5

The nurse is evaluating a patient's laboratory results. Based upon the laboratory findings, what results will cause the release of an antidiuretic hormone (ADH)?

Correct Answer: A

Rationale: Increased serum sodium causes increased thirst and the release of ADH by the posterior pituitary gland.

Question 3 of 5

A patient is in the hospital with heart failure. The nurse notes during the evening assessment that the patient's neck veins are distended and the patient has dyspnea. What action should the nurse take?

Correct Answer: C

Rationale: The symptoms of neck vein distention and dyspnea suggest fluid overload. Placing the patient in semi-Fowler's position and administering diuretics can help reduce fluid volume and improve breathing.

Question 4 of 5

A nurse admitting a patient with a history of emphysema reviews her past lab reports and notes that the patient's PaCO2 has been 56 to 64 mmHg. The nurse will be cautious administering oxygen because:

Correct Answer: D

Rationale: When PaCO2 chronically exceeds 50 mm Hg, it creates insensitivity to CO2 in the respiratory medulla, and the use of oxygen may result in the patient developing carbon dioxide narcosis and hypoxemia.

Question 5 of 5

A patient who is hospitalized with a possible electrolyte imbalance is disoriented and weak, has an irregular pulse, and takes hydrochlorothiazide. He most likely suffers from:

Correct Answer: D

Rationale: The symptoms of hypokalemia include GI, cardiac, renal, respiratory, and neurologic disturbances. The use of potassium-wasting diuretics, such as hydrochlorothiazide, without potassium replacement therapy is a primary cause of hypokalemia.
