ATI Fluid Electrolyte and Acid-Base Regulation

1. A nurse is caring for clients with electrolyte imbalances on a medical-surgical unit. Which clinical manifestations are correctly paired with the contributing electrolyte imbalance? (Select all that do not apply.)

A. Hypokalemia Flaccid paralysis with respiratory depression
B. Hyperphosphatemia Paresthesia with sensations of tingling and numbness
C. . Hyponatremia Decreased level of consciousness
D.

Correct answer: B

Rationale:

2. When considering overhydration:

A. occurs less often than dehydration.
B. can strain the kidneys.
C. can be caused by giving intravenous fluids too rapidly.
D. less common than dehydration.

Correct answer: C

Rationale: The correct answer is C. Overhydration can occur when intravenous fluids are administered too quickly, overwhelming the body's ability to excrete the excess fluid. Choices A, B, and D are incorrect. Choice A is incorrect because overhydration is less common than dehydration. Choice B is incorrect because while overhydration can strain the kidneys, it is not due to the burden being too heavy. Choice D is incorrect because dehydration is more common than overhydration.

3. You are caring for a patient with a diagnosis of pancreatitis. The patient was admitted from a homeless shelter and is a vague historian. The patient appears malnourished and on day 3 of the patients admission total parenteral nutrition (TPN) has been started. Why would you know to start the infusion of TPN slowly?

A. Patients receiving TPN are at risk for hypercalcemia if calories are started too rapidly.
B. Malnourished patients receiving parenteral nutrition are at risk for hypophosphatemia if calories are started too aggressively.
C. Malnourished patients who receive fluids too rapidly are at risk for hypernatremia.
D. Patients receiving TPN need a slow initiation of treatment in order to allow digestive enzymes to accumulate

Correct answer: B

4. What electrolyte value should be monitored when a patient is receiving a loop diuretic?

A. Calcium levels
B. Phosphorus levels
C. Potassium levels
D. Magnesium levels

Correct answer: C

Rationale: When a patient is receiving a loop diuretic like furosemide (Lasix), potassium levels should be monitored closely. Loop diuretics act on the ascending loop of Henle to inhibit the reabsorption of sodium and water, leading to potassium loss. Monitoring potassium levels is crucial to prevent hypokalemia, which can result in serious complications such as cardiac arrhythmias. Calcium levels (Choice A), phosphorus levels (Choice B), and magnesium levels (Choice D) are not typically affected directly by loop diuretics and do not require routine monitoring in this context.
