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.) mL.

This is because swelling of the feet can be a sign of lithium toxicity, which is a serious condition that can occur when the level of lithium in the blood is too high. Lithium toxicity can cause confusion, irregular heartbeat, muscle weakness, and kidney problems. Therefore, the client should report any signs of lithium toxicity to their provider as soon as possible.

Choice A is wrong because limiting foods containing tyramine is not necessary for clients taking lithium. Tyramine is a substance found in some foods that can interact with certain antidepressants called monoamine oxidase inhibitors (MAOIs), but not with lithium.

Choice B is wrong because decreasing the daily sodium intake can actually increase the risk of lithium toxicity.

Sodium helps to regulate the amount of lithium in the body, so if the sodium level is low, the lithium level can rise too high.

The client should maintain a normal sodium intake and drink enough fluids while taking lithium.

Choice C is wrong because taking this medication 2 hours before a meal is not required for clients taking lithium.

Lithium can be taken with or without food, but it should be taken at the same time each day to keep a steady level in the blood.

Taking lithium 2 hours before a meal may cause stomach upset, which is a common side effect of lithium.

The correct answer is d

Choice A reason:

Administering filgrastim 12 hours after chemotherapy does not typically require an incident report. Filgrastim is often given at least 24 hours after chemotherapy to avoid the risk of increasing the toxicity of the chemotherapy agents. While the timing is closer than recommended, it does not necessarily constitute an error unless specific instructions for the timing were provided by the prescribing physician.

Choice B reason:

The medication vial sitting at room temperature for 2 hours before administration does not require an incident report. Filgrastim can be left out at room temperature for up to 24 hours before use. This is within the safe handling guidelines for the medication.

Choice C reason:

An absolute neutrophil count (ANC) of 2,500/mm³ is within the normal range, which is typically 1,500-8,000/mm³. Filgrastim is used to increase neutrophil counts in patients with low ANC due to chemotherapy. Since the ANC was not low before administration, this would not necessitate an incident report, although it may prompt a review of the necessity of the medication.

Choice D reason:

Flushing the client's IV line with dextrose 5% in water before and after the medication was administered is not the standard procedure and could potentially lead to medication errors or adverse effects. Filgrastim should be diluted in glucose 5% in water for intravenous infusion, but not used to flush the line. This deviation from the standard protocol is what necessitates an incident report.
