The nurse points out that electrolytes are essential for health. Nonelectrolytes include:

Amino acids

Magnesium

Phosphates

Glucose

Answer and Explanation

The Correct Answer is D

Choice A reason: This is incorrect because amino acids are electrolytes. Electrolytes are substances that dissociate into ions when dissolved in water and conduct electricity. Amino acids have both positive and negative charges and can form ions in solution.

Choice B reason: This is incorrect because magnesium is an electrolyte. Magnesium is a metal that forms positive ions (cations) when dissolved in water. Magnesium is important for muscle and nerve function, as well as bone health.

Choice C reason: This is incorrect because phosphates are electrolytes. Phosphates are compounds that contain the phosphate ion (PO4 3-), which is a negative ion (anion) in solution. Phosphates are involved in energy metabolism, acid-base balance, and bone formation.

Choice D reason: This is correct because glucose is a nonelectrolyte. Nonelectrolytes are substances that do not dissociate into ions when dissolved in water and do not conduct electricity. Glucose is a simple sugar that dissolves as a whole molecule in water. Glucose is the main source of energy for the body.

Correct Answer is C

Explanation

Choice A reason: This is incorrect because this represents respiratory alkalosis, not acidosis. Respiratory alkalosis is characterized by a high pH and a low PCO2.

Choice B reason: This is incorrect because this represents a mixed disorder, not a pure respiratory acidosis. A mixed disorder occurs when both the pH and the PCO2 are abnormal, but in opposite directions.

Choice C reason: This is correct because this represents respiratory acidosis. Respiratory acidosis is characterized by a low pH and a high PCO2.

Choice D reason: This is incorrect because this represents normal values, not respiratory acidosis. Normal values for pH and PCO2 are 7.35 to 7.45 and 35 to 45 mmHg, respectively.

A. 2200 mL B. 3000 mL C. 3800 mL D. 2400 mL

Correct Answer is A

Explanation

Choice A reason: For an average adult, the total intake should be approximately equal to the total output every day¹². Therefore, if the patient's total output is 2200 mL, the total intake should also be around 2200 mL.

Choice B reason: 3000 mL is more than the recommended daily fluid intake for an average adult, which is about 2500 mL³. If the patient's intake is higher than their output, they may develop fluid overload or edema.

Choice C reason: 3800 mL is much more than the recommended daily fluid intake for an average adult, which is about 2500 mL³. If the patient's intake is higher than their output, they may develop fluid overload or edema.

Choice D reason: 2400 mL is slightly less than the recommended daily fluid intake for an average adult, which is about 2500 mL³. However, if the patient's intake is lower than their output, they may develop dehydration or electrolyte imbalance.
