Correct Answer is A

Explanation

A. Place the patient on a cardiac monitor and check the patency of the IV: Hypokalemia (K+ = 2.5 mEq/L) can cause life-threatening cardiac dysrhythmias, so cardiac monitoring is essential. Additionally, potassium is highly irritating to veins, so IV patency must be confirmed to prevent extravasation and tissue damage.

B. Administer potassium intravenously in an IV push bolus- NEVER give potassium IV push as it can cause fatal cardiac arrest. Potassium must always be diluted and infused slowly.

C. Discontinue other medications that may affect potassium levels- Adjusting medications may be necessary, but not an immediate priority over cardiac monitoring.

D. Avoid potassium-rich foods in the diet - Incorrect because the client needs potassium replacement, not restriction.

A. 0.2 mg B. 0.20 mg C. 12 mg D. 2.0 mg

Correct Answer is A

Explanation

A. 0.2 mg: The correct way to write decimal doses is with a leading zero (0.2) to prevent misinterpretation.

B. 0.20 mg: Trailing zeros (0.20) should be avoided because they increase the risk of dosing errors (e.g., misread as "20 mg").

C. 12 mg: Not equivalent to 0.2 mg; incorrect dose.

D. 2.0 mg: Not equivalent to 0.2 mg, and trailing zeros should be avoided.
