Fluid and Electrolytes ATI Questions

Question 1 of 5

A nurse in the medical-surgical unit has a newly admitted patient who is oliguric; the acute care nurse practitioner orders a fluid challenge of 100 to 200 mL of normal saline solution over 15 minutes. The nurse is aware this intervention will help:

Correct Answer: C

Rationale: If a patient is not excreting enough urine, the health care provider needs to determine whether the depressed renal function is the result of reduced renal blood flow, which is a fluid Volume deficit (FVD) or prerenal azotemia, or acute tubular necrosis that results in necrosis or cellular death from prolonged FVD. A typical example of a fluid challenge involves administering 100 to 200 mL of normal saline solution over 15 minutes. The response by a patient with FVD but normal renal function is increased urine output and increased blood pressure.

Question 2 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 3 of 5

The nurse working in the PACU is aware that which of the following procedures may contribute to extracellular losses?

Correct Answer: C

Rationale: Fluid loss from the extracellular compartment can be caused by abdominal surgery.

Question 4 of 5

When selecting a site on the hand or arm for insertion of an IV catheter, the nurse should:

Correct Answer: B

Rationale: When selecting a site for insertion of an IV catheter, the nurse should choose a distal site, not a proximal site. Selection of a distal site leaves the upper veins available for subsequent cannulations. Instruct the patient to hold his arm in a dependent position to increase blood flow. Never leave a tourniquet in place longer than 2 minutes.

Question 5 of 5

Which of the following might the nurse assess in a patient diagnosed with hypermagnesemia?

Correct Answer: A

Rationale: To gauge a patient's magnesium status, the nurse should check deep tendon reflexes. If the reflex is absent, this may indicate high serum magnesium.
