A nurse is preparing to administer potassium chloride elixir 20 mEq/day PO to divide equally every 12 hr. Available is 6.7 mEq/5 mL. How many mL should the nurse administer per dose?

(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["7.5"]

The correct answer is 7.5 ML

To answer this question, we need to use the formula:

mL to administer = (mEq ordered / mEq available) x mL available Plugging in the values from the question, we get:

mL to administer = (20 mEq/day / 6.7 mEq/5 mL) x 5 mL Simplifying, we get:

mL to administer = (2.99 mL/mEq) x 5 mL Multiplying, we get:

mL to administer = 14.95 mL/day

Since the order is to divide the dose equally every 12 hours, we need to divide the total daily dose by 2:

mL to administer per dose = 14.95 mL/day / 2 Dividing, we get:

mL to administer per dose = 7.475 mL

Rounding to the nearest tenth, we get:

mL to administer per dose = 7.5 mL

Therefore, the nurse should administer 7.5 mL of potassium chloride elixir per dose.

Correct Answer is C

Explanation

Choice A rationale:

Ringing in the ears is not typically associated with clozapine.

Choice B rationale:

Diarrhea is not a common adverse effect of clozapine.

Choice C rationale:

Clozapine can cause agranulocytosis, a serious condition involving a decrease in white blood cells. Fever can be a sign of infection, so clients taking clozapine should notify their provider if they develop a fever.

Choice D rationale:

Weight loss is not a common adverse effect of clozapine.

A. The nurse flushed the client's IV line with dextrose 5% in water before and after the medication was administered. B. The client's absolute neutrophil count was 2.500/mm3 before the medication was administered. C. The client had chemotherapy 12 hr before the medication was administered. D. The medication vial sat at room temperature for 2 hr before it was administered.

Correct Answer is D

Explanation

A: Flushing an IV line with dextrose 5% in water before and after medication administration is a common practice to ensure that the medication is delivered properly and to prevent interactions in the IV line. This would not typically require an incident report.
B: An absolute neutrophil count of 2.500/mm3 is within the normal range for patients undergoing chemotherapy and would not typically necessitate an incident report.
C: Having chemotherapy 12 hours before the administration of filgrastim does not contraindicate its use and is within the appropriate time frame as filgrastim is often given after chemotherapy to help recover white blood cell counts.
D: According to the guidelines, filgrastim should be stored in the refrigerator and allowing it to sit at room temperature for 2 hours could compromise its effectiveness. This is a deviation from the medication's storage requirements and could potentially harm the patient, thus an incident report should be filed.
