A nurse is caring for a client who is taking azathioprine to treat rheumatoid arthritis. Which of the following laboratory values indicates an adverse effect of this medication?

Choice A Reason:
Discard the medication if it is yellow is incorrect. While amphotericin B lipid complex can have a yellowish color, it's important to follow specific guidelines provided by the manufacturer or pharmacy regarding any discoloration or changes in the medication's appearance. Discoloration could indicate degradation or contamination, and it's crucial to adhere to specific institutional policies in such cases.
Choice B Reason:
Administer the medication over 2 hr is incorrect. Amphotericin B lipid complex is usually given over a longer duration (e.g., several hours) due to the potential for infusion-related reactions. Intermittent IV bolus administration over 2 hours might not be appropriate and can increase the risk of adverse reactions.
Choice C Reason:
Use a gravity flow set is incorrect. For medications like amphotericin B lipid complex, which often require precise infusion rates and careful monitoring, using an IV infusion pump is usually recommended instead of a gravity flow set. An infusion pump allows for more accurate control of the infusion rate and reduces the risk of errors.
Choice D Reason:
Prime the tubing with 0.9% sodium chloride is correct. Amphotericin B lipid complex should be administered according to specific instructions and precautions. Priming the IV tubing with 0.9% sodium chloride helps ensure that the medication is effectively delivered to the patient and that the medication is not affected by remnants of previous IV solutions in the tubing.

Choice A Reason:
Blood pressure is correct. Nitroprusside is a medication used to lower blood pressure in conditions such as hypertensive emergencies. It's titrated based on blood pressure readings, with the goal of achieving the desired target blood pressure range as directed by the healthcare provider. The nurse would monitor the client's blood pressure closely and adjust the infusion rate accordingly to achieve the prescribed blood pressure parameters.
Choice B Reason:
Stroke volume is incorrect. While stroke volume (the amount of blood ejected by the heart with each contraction) is important in assessing heart function, it's not directly used to titrate a nitroprusside infusion. Nitroprusside primarily acts as a vasodilator to reduce blood pressure, rather than affecting stroke volume.
Choice C Reason:
Cardiac output is incorrect. Cardiac output (the volume of blood pumped by the heart per minute) is also a crucial measure of heart function, but adjusting a nitroprusside infusion based on cardiac output is not a common practice. Nitroprusside's primary action is to dilate blood vessels, impacting blood pressure regulation more directly than cardiac output.
Choice D Reason:
Urine output is incorrect. While urine output is an important indicator of renal function and overall fluid balance, it is not typically used as the main parameter for titrating nitroprusside. Nitroprusside's primary effect is on vasodilation and blood pressure control rather than directly impacting urine output.
