Fluid and Electrolytes ATI Questions

Question 1 of 5

A nurse is taking care of a 65-year-old female patient in a medical-surgical unit who is in renal failure; during the assessment the patient complains of tingling in her lips and fingers. When the nurse takes her blood pressure, she has a spasm in her wrist and hand. The nurse suspects:

Correct Answer: B

Rationale: Tetany is the most characteristic manifestation of hypocalcemia and hypomagnesemia. Sensations of tingling may occur in the tips of the fingers, around the mouth, and less commonly in the feet. Taking a normal blood pressure could illicit a carpal spasm if it creates slight ischemia of the ulnar nerve.

Question 2 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 3 of 5

A patient who is in renal failure partially loses the ability to regulate changes in pH because the kidneys:

Correct Answer: C

Rationale: The kidneys regulate the bicarbonate level in the ECF; they can regenerate bicarbonate ions as well as reabsorb them from the renal tubular cells. In respiratory acidosis and most cases of metabolic acidosis, the kidneys excrete hydrogen ions and conserve bicarbonate ions to help restore balance.

Question 4 of 5

A patient is receiving furosemide (Lasix) 40 mg/d IV. What electrolyte value should be monitored when a patient is receiving a loop diuretic?

Correct Answer: C

Rationale: The diuretics act on the ascending loop of Henle to prevent re-absorption of water, potassium, and sodium. Because of this, potassium and sodium levels should be monitored when a patient is receiving diuretics.

Question 5 of 5

The nurse is assessing the patient for the presence of a Chvostek's sign. What electrolyte imbalance does a positive Chvostek's sign indicate?

Correct Answer: C

Rationale: A brief contraction of the upper lip, nose, or side of the face indicates Chvostek's sign, which is associated with hypocalcemia.
