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 D

Explanation

Choice A rationale:

A history of nausea with cefuroxime is a common side effect and may not be the highest priority to report.

Choice B rationale:

A BUN level of 18 mg/dL is within the normal range and may not be an immediate concern.

Choice C rationale:

Taking aspirin daily may have some interactions with cefuroxime, but a history of a severe penicillin allergy is more critical to report.

Choice D rationale:

Cefuroxime is a cephalosporin antibiotic, and individuals with a severe penicillin allergy may have an increased risk of cross-reactivity with cephalosporins. This history should be reported to the provider for further assessment and consideration of alternative antibiotics.

A. INR 1.6 B. WBC 6,000/mm3 C. Hgb 16 g/dL D. aPTT 90 seconds

Correct Answer is D

Explanation

Choice A rationale:

An INR of 1.6 is slightly elevated but does not necessarily warrant an incident report.

Choice B rationale:

A WBC count of 6,000/mm3 is within a normal range and would not warrant an incident report.

Choice C rationale:

A hemoglobin level of 16 g/dL is within a normal range and does not warrant an incident report.

Choice D rationale:

An aPTT of 90 seconds is significantly prolonged and may indicate excessive anticoagulation from the heparin administration. This could potentially be a safety concern and would warrant an incident report for further evaluation.
