To prevent medication errors and reduce the possibility of causing harm to a patient, the provider should always use a _____

Trailing

Double

Leading

Decimal point

Answer and Explanation

The Correct Answer is C

A. Trailing: Incorrect because trailing zeros (e.g., 5.0 mg) should be avoided, as 5.0 mg could be misread as 50 mg.

B. Double: Not relevant to numeric safety measures.

C. Leading: A leading zero (e.g., 0.5 mg instead of .5 mg) helps prevent medication errors. Without a leading zero, .5 mg could be misread as 5 mg, leading to a dangerous overdose.

Correct Answer: C

D. Decimal point: This refers to the proper use of decimal points in dose documentation. While using decimal points is critical, this alone doesn’t address all potential errors related to formatting (e.g., leading or trailing zeros).

Correct Answer is A

Explanation

A. "This test will inform your provider how your kidneys are functioning." Creatinine is a waste product from muscle metabolism and is excreted by the kidneys. Elevated creatinine levels indicate impaired kidney function.

B. "This test will inform your provider if you have a thyroid disorder." Thyroid disorders are typically diagnosed with TSH, T3, and T4 tests, not creatinine.

C. "This test will inform your provider if you have an infection." Infections are usually diagnosed with CBC (WBC count) or cultures, not creatinine.

D. "This test will inform your provider if you are anemic." Anemia is diagnosed with hemoglobin and hematocrit (H&H), not creatinine levels.

A. Place the patient on a cardiac monitor and check the patency of the IV B. Administer potassium intravenously in an IV push bolus C. Discontinue other medications that may affect potassium levels D. Avoid potassium rich foods in the diet

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.
