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. A vein that feels hard to the touch:
A vein that feels hard to the touch may indicate thrombosis or inflammation and is not a suitable site for catheter insertion.
B. A vein in the client's dominant arm:
The choice of arm may depend on the client's preference, but it is not a strict rule. The nurse can choose a suitable vein in either arm based on factors such as accessibility and vein condition.
C. A vein proximal to the previous site:
This is the correct answer. Placing the catheter proximal (above or upstream) to the previous site helps minimize the risk of complications such as infiltration and thrombophlebitis at the new site. It allows for optimal vein health and reduces the likelihood of complications associated with repeated punctures in the same area.
D. A vein on the client's wrist:
Veins on the wrist may be smaller and more prone to complications. It is generally recommended to choose larger, more accessible veins for catheter insertion.

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.
