A nurse is preparing to administer potassium chloride (KCL). The provider prescribes potassium chloride (KCL) 20 mEq suspension PO daily. The bottle is labeled KCL elixir, 10 mEq/mL. Which of the following should the nurse administer?

2 mL.

2.5 mL.

1.5 mL.

1 mL.

Answer and Explanation

The Correct Answer is A

Choice A rationale:
The provider prescribes 20 mEq of KCL. The bottle is labeled as 10 mEq/mL. Therefore, to administer 20 mEq, the nurse should give 2 mL (20 mEq ÷ 10 mEq/mL = 2 mL).
Choice B rationale:
Administering 2.5 mL would give 25 mEq of KCL, which is more than the prescribed dose.
Choice C rationale:
Administering 1.5 mL would give 15 mEq of KCL, which is less than the prescribed dose.
Choice D rationale:
Administering 1 mL would give 10 mEq of KCL, which is half the prescribed dose.

Correct Answer is B

Explanation

Choice A rationale:
Reminding the client not to turn from side to side is not the most appropriate action. While it is important to limit movement after a cardiac catheterization, it is not the most critical action.
Choice B rationale:
Checking pedal pulses every 15 min is the most appropriate action. This is to monitor for signs of vascular compromise, which can occur after a cardiac catheterization with a femoral artery approach.
Choice C rationale:
Keeping the client in high-Fowler’s position for 6 hr is not the most appropriate action. While positioning can be important, it is not the most critical action after a cardiac catheterization with a femoral artery approach.
Choice D rationale:
Performing passive range-of-motion for the affected extremity is not the most appropriate action. While it is important to maintain mobility, it is not the most critical action after a cardiac catheterization with a femoral artery approach.

A. Pulmonary artery. B. Aorta. C. Inferior vena cava. D. Pulmonary vein.

Correct Answer is B

Explanation

Choice A rationale:
The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs, not from the left ventricle.
Choice B rationale:
The aorta is the main and largest artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen.
Choice C rationale:
The inferior vena cava carries deoxygenated blood from the lower half of the body back to the right atrium of the heart, not from the left ventricle.
Choice D rationale:
The pulmonary vein carries oxygenated blood from the lungs to the left atrium, not from the left ventricle.
