A nurse is reviewing the arterial blood gas (ABG) values of a client who has chronic kidney disease. Which of the following sets of values should the nurse expect?
pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg
pH 7.50, HCO3- 20 mEq/L, PaCO2 32 mm Hg
pH 7.55, HCO3- 30 mEq/L, PaCO2 31 mm Hg
pH 7.30, HCO3- 26 mEq/L, PaCO2 50 mm Hg
The Correct Answer is A
Choice A reason:
This set of values indicates metabolic acidosis, which is common in chronic kidney disease due to the accumulation of acids in the body as the kidneys fail to eliminate them effectively³.
Choice B reason:
A pH of 7.50 is considered alkalotic, and while HCO3- and PaCO2 are within normal ranges, this set of values does not typically represent chronic kidney disease.
Choice C reason:
A pH of 7.55 is also alkalotic, and an HCO3- of 30 mEq/L indicates metabolic alkalosis, which is not characteristic of chronic kidney disease.
Choice D reason:
While a pH of 7.30 is on the lower end of the normal range, an HCO3- of 26 mEq/L is within the normal range, and a PaCO2 of 50 mm Hg indicates respiratory acidosis, not typically seen in chronic kidney disease without concurrent respiratory issues.

Correct Answer is D
Explanation
Choice A reason:Atrial fibrillation is not typically treated with defibrillation; it is usually managed with medication or other forms of rhythm control.
Choice B reason:Supraventricular tachycardia does not usually require defibrillation; it may be treated with vagal maneuvers or medication.
Choice C reason:Asystole, or the absence of a heartbeat, is not treated with defibrillation as there is no electrical activity to reset.
Choice D reason:Ventricular fibrillation is a life-threatening heart rhythm that requires immediate defibrillation to restore a normal heart rhythm.
Correct Answer is ["35"]
Explanation
- Step 1: Identify the total volume to be administered. The nurse is scheduled to administer 840 mL of enteral nutrition over a 24-hour period.
- Step 2: Identify the total time over which the volume is to be administered. The total time is 24 hours.
- Step 3: Calculate the rate at which the infusion pump should be set. We can do this by dividing the total volume by the total time:
- Rate = Total Volume ÷ Total Time.
- Rate = 840 mL ÷ 24 hours.
- Calculating the division gives us: Rate = 35 mL/hr.
set the infusion pump to deliver 35 mL/hr.
