A nurse is caring for a client who is taking digoxin to treat heart failure. Which of the following factors predisposes this client to developing digoxin toxicity?

The correct answer is d. Administer the medication over 2 hr.

Choice A reason: Discarding the medication if it is yellow is not necessary. The color of amphotericin B lipid complex does not indicate its effectiveness or safety.

Choice B reason: Using a gravity flow set is not specifically required for the administration of amphotericin B lipid complex. Gravity infusion can be used to administer fluids and drugs where the rate is not critical and serious adverse effects are not anticipated. However, the use of a gravity flow set is not specifically mentioned in the guidelines for administering amphotericin B lipid complex.

Choice C reason: Priming the tubing with 0.9% sodium chloride is not recommended for amphotericin B lipid complex. This is because amphotericin B lipid complex is incompatible with saline solutions and should be diluted only with 5% dextrose injection. Priming the tubing is a common practice in IV therapy to remove air from the tubing before attaching it to the patient.

Choice D reason: Administering the medication over 2 hr is the correct action. Amphotericin B lipid complex is typically administered over a longer period, often 2-6 hours. This allows for a slow and steady delivery of the medication, which can help to minimize potential side effects.

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.
