ATI Fluid and Electrolytes

1. What fluid is found in spaces between the cells?

Correct answer: B

Rationale: The correct answer is B, Interstitial fluid. Interstitial fluid is the fluid that surrounds and occupies the spaces between cells, providing them with nutrients and removing waste. Choices A, C, and D are incorrect because intracellular fluid refers to fluid inside cells, plasma refers to the liquid component of blood, and electrolyte refers to substances that dissociate into ions in solution, affecting fluid balance but not specifically found in spaces between cells.

2. A patient who is being treated for pneumonia starts complaining of sudden shortness of breath. An arterial blood gas (ABG) is drawn. The ABG has the following values: pH 7.21, PaCO2 64 mm Hg, HCO3 = 24 mm Hg. What does the ABG reflect?

Correct answer: A

Rationale:

3. . A nurse assesses a client with diabetes mellitus who is admitted with an acid-base imbalance. The clients arterial blood gas values are pH 7.36, PaO2 98 mm Hg, PaCO2 33 mm Hg, and HCO3 18 mEq/L. Which manifestation should the nurse identify as an exam

Correct answer: A

Rationale:

4. What percentage of body water can be as high as in a newborn?

Correct answer: A

Rationale: The correct answer is A: 80%. Newborns can have a body water content as high as 80% due to their higher total body water compared to adults. Choice B (70%) is incorrect because newborns typically have a higher body water percentage. Choice C (60%) is also incorrect as it underestimates the body water content in newborns. Choice D (90%) is incorrect as it overestimates the body water percentage in newborns.

5. A client with a serum potassium of 7.5 mEq/L and cardiovascular changes needs immediate intervention. Which prescription should the nurse implement first?

Correct answer: C

Rationale: In a client with a serum potassium level of 7.5 mEq/L and cardiovascular changes, the priority intervention is to lower the potassium level quickly to prevent life-threatening complications like arrhythmias. The correct answer is to prepare to administer dextrose 20% and 10 units of regular insulin IV push. This combination helps shift potassium from the extracellular to the intracellular space, reducing serum potassium levels rapidly. Administering sodium polystyrene sulfate (Kayexalate) by mouth may take several hours to work, making it a less effective immediate intervention. Providing a heart-healthy, low-potassium diet is important for long-term management but is not the most urgent action in this situation. While hemodialysis is a definitive treatment for hyperkalemia, it is not the first-line intervention for acute management of high potassium levels with cardiovascular manifestations.
