A nurse is caring for a client who requires a re-insertion of a short peripheral venous catheter. in which of the following locations should the nurse place the catheter?
A vein that feels hard to the touch
A vein in the client's dominant arm
A vein proximal to the previous site
A vein on the client's wrist
The Correct Answer is C
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. Orthostatic hypotension:
Orthostatic hypotension is not a common adverse effect of pioglitazone. This condition is more associated with medications that affect blood pressure or volume.
B. Tinnitus:
Tinnitus (ringing in the ears) is not typically associated with pioglitazone. Adverse effects of pioglitazone are more related to its impact on glucose metabolism and other metabolic processes.
C. Fluid retention:
This is the correct answer. Fluid retention is a known adverse effect of pioglitazone. It can lead to edema, weight gain, and, in some cases, exacerbation of heart failure. Monitoring for signs of fluid retention is important during treatment with pioglitazone.

Insomnia is not a common adverse effect of pioglitazone. Adverse effects are more related to metabolic processes, and sleep disturbances are not typically associated with this medication.
Correct Answer is ["60"]
Explanation
1.Convert the available lidocaine concentration to mg/mL:
2 g of lidocaine = 2000 mg
2000 mg ÷ 500 mL = 4 mg/mL
2. Determine the mL/min required to deliver 4 mg/min:
4 mg/min ÷ 4 mg/mL = 1 mL/min
3. Convert mL/min to mL/hr:
1 mL/min × 60 minutes = 60 mL/hr
