LPN Reduction of Risk Potential 3

Question 1

A client is prescribed potassium chloride 40 mEq IV. Which action is correct for the LPN?

Accepted Answer

Dilute it and infuse no faster than 10 mEq/hour peripherally

Answer

IV potassium must always be diluted and infused slowly (no more than 10 mEq/hr peripherally) to prevent cardiac arrhythmias and vein irritation.

Question 2

Which finding in a client receiving a blood transfusion requires the LPN to stop the transfusion immediately?

Accepted Answer

Chills, back pain, and dark urine

Answer

Chills, flank/back pain, and hemoglobinuria (dark urine) are classic signs of an acute hemolytic transfusion reaction, which is life-threatening.

Question 3

A client with a history of seizures is admitted. Which environmental modification is the highest priority?

Accepted Answer

Pad the side rails and keep them raised

Answer

Padding and raising side rails protects the client from injury if a seizure occurs while in bed.

Question 4

The LPN is reviewing a client's medication list prior to a scheduled CT scan with contrast dye. Which medication should be flagged for the charge nurse?

Accepted Answer

Metformin

Answer

Metformin must be held before contrast administration because contrast-induced nephropathy can lead to lactic acidosis in clients taking metformin.

Question 5

A client has a peripherally inserted central catheter (PICC). Which observation requires immediate action by the LPN?

Accepted Answer

Arm swelling and pain at the PICC site

Answer

Arm swelling and pain at the PICC site can indicate thrombosis or infiltration, both of which require prompt assessment and intervention.
