A nurse is preparing to administer cimetidine 300 mg IV over 15 min to a client. Available is cimetidine 300 mg/100 mL of 0.9% sodium chloride. The nurse should set the IV pump to deliver how many mL/hr?
(Round the answer to the nearest whole number. Use a leading zero if it applies. Done use a trailing zero.)

A. Discard the medication if it is yellow: Amphotericin B lipid complex is typically yellow in color. This is a normal characteristic of the medication, and it should not be discarded based on color. The nurse should be aware of the expected color and administer the medication as prescribed.
B. Administer the medication over 2 hr: Amphotericin B lipid complex is often administered over an extended period (usually over 2 to 6 hours) to minimize the risk of infusion-related reactions. However, if the prescription specifies an intermittent IV bolus, the nurse should follow the prescribed administration route and rate.
C. Prime the tubing with 0.9% sodium chloride (Correct Answer): Amphotericin B lipid complex can interact with dextrose-containing solutions, leading to the formation of a precipitate. Therefore, it is recommended to prime the IV tubing with 0.9% sodium chloride before administering the medication to prevent any potential interaction.
D. Use a gravity flow set: The choice of infusion set may depend on the specific institutional policies and the patient's condition. However, using a pump or a controlled infusion device is often recommended when administering medications like amphotericin B to ensure accurate infusion rates and reduce the risk of adverse reactions.

A. Withhold the medication: An INR of 2.5 is generally within the therapeutic range for many conditions, including atrial fibrillation. Withholding the medication might lead to a decreased INR, potentially increasing the risk of clotting.
B. Decrease the dose of the medication: If the INR is above the therapeutic range (usually 2.0-3.0 for atrial fibrillation), the provider might consider decreasing the dose. However, an INR of 2.5 is within the typical therapeutic range, so a decrease in dose might not be warranted.
C. Increase the dose of the medication: An INR of 2.5 is generally within the therapeutic range for many conditions. Increasing the dose in this situation could elevate the INR further, potentially leading to an increased risk of bleeding.
D. Administer the current dose of the medication: Since the INR is within the therapeutic range, the nurse should expect the provider to maintain the current dose of warfarin. Adjustments to the dose might be considered if the INR deviates significantly from the target range.
