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

Answer and Explanation

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.

Correct Answer is C

Explanation

A. Hypomagnesemia: While exercise can cause some magnesium loss through sweat, lithium is not specifically associated with magnesium imbalance. The primary concern in this scenario is related to sodium levels due to the impact of both exercise and lithium.
B. Hypokalemia: Exercise might also lead to potassium loss through sweat. However, potassium levels are not specifically affected by lithium in the same way as sodium levels. Hyponatremia is a more significant concern in this context.
C. Hyponatremia: Exercise-induced sodium loss compounded with lithium's potential to disrupt sodium balance increases the risk of hyponatremia. It's essential to monitor sodium levels in individuals on lithium who start new exercise programs.
D. Hypocalcemia: Exercise itself doesn't directly lead to significant calcium imbalances. Additionally, lithium is not associated with disturbances in calcium levels to the extent that it is with sodium levels.

A. Hydromorphone B. Aspirin C. Caldoler D. Meloxicam

Correct Answer is A

Explanation

A. Hydromorphone: This is a potent opioid analgesic and is commonly used for the management of severe pain, especially in cancer patients. It provides strong pain relief and is often used in situations where other pain medications are not sufficient.
B. Aspirin: Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) with anti-inflammatory and analgesic properties. While it may be used for pain relief in some situations, it is not typically the first choice for severe pain in pancreatic cancer.
C. Acetaminophen (Caldoler): Acetaminophen is a non-opioid analgesic and antipyretic. It is not as potent as opioids and may not be sufficient for managing severe pain, especially in the context of advanced cancer.

D. Meloxicam: Meloxicam is a nonsteroidal anti-inflammatory drug (NSAID) and is not the first-line choice for severe pain, particularly in cancer patients. Opioid analgesics are generally preferred for managing severe pain in cancer.
