A nurse is preparing to administer 4,000 units of heparin subcutaneously to a client who has deep-vein thrombosis. Available is heparin 10,000 units/mL. How many mL of heparin should the nurse administer?

(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 ["0.4"]

To answer this question, we need to use the formula for calculating the dosage of medication:

Dose ordered / Dose on hand = Amount to administer

The calculation is: 4,000 units / 10,000 units/mL = 0.4 mL.

Correct Answer is B

Explanation

Choice A rationale:

Lithium carbonate should be taken with meals to minimize gastrointestinal upset.

Choice B rationale:

Lithium levels can be affected by sodium intake, so decreasing sodium intake can help prevent lithium toxicity.

Choice C rationale:

Tyramine is not typically restricted in clients taking lithium.

Choice D rationale:

Swelling of the feet is not a common adverse effect of lithium carbonate.

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.
