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 ["1140"]

Explanation

To calculate the total intake, we need to convert all measurements to mL. 1 oz is approximately 30 mL, 1 cup is approximately 240 mL. So, 4 oz of soda is 120 mL, 12 oz of water is 360 mL, 1 cup of gelatin is 240 mL, and 1/2 cup of broth is 120 mL. Adding these to the 300 mL of IV fluid gives us 1140 mL. However, the toast is not a liquid and cannot be measured in mL, so it is not included in the total intake.

A. Keep the client NPO after midnight. B. Inspect the electrode pads. C. Instruct the client to breathe normally. D. Administer an analgesic prior to the procedure. E. Use alcohol to wipe the skin before placing the electrodes.

Correct Answer is ["B","C","E"]

Explanation

Choice A rationale:
Keeping the client NPO after midnight is not necessary for an ECG. It is a non-invasive procedure that does not require fasting.
Choice B rationale:
Inspecting the electrode pads is important to ensure good contact with the skin and accurate readings.
Choice C rationale:
Instructing the client to breathe normally during the ECG helps to prevent artifacts in the tracing that could lead to misinterpretation.
Choice D rationale:
Administering an analgesic prior to the procedure is not necessary. An ECG is a painless procedure.
Choice E rationale:
Using alcohol to wipe the skin before placing the electrodes can improve the quality of the ECG by reducing skin impedance.
