Question 1

A patient is ordered to receive IV potassium chloride 40 mEq in 100 mL NS over 1 hour. What is the safest administration method?

Accepted Answer

Via infusion pump through a peripheral IV

Which assessment finding indicates that a patient with a urinary catheter may have a catheter-associated urinary tract infection (CAUTI)?

Cloudy, foul-smelling urine with fever

Answer

Cloudy, foul-smelling urine accompanied by fever and possibly flank pain or confusion are hallmark signs of a CAUTI.

Question 3

An LPN is educating a patient about warfarin therapy. Which food should the patient be instructed to consume consistently rather than avoid entirely?

Accepted Answer

Leafy green vegetables

Answer

Leafy green vegetables high in vitamin K can affect warfarin's effectiveness; patients should eat consistent amounts rather than eliminate them to maintain stable INR levels.

Question 4

A patient with a hip fracture repair is being positioned in bed. Which position is contraindicated?

Accepted Answer

Side-lying with affected hip adducted past midline

Adduction of the affected hip past the midline risks prosthetic hip dislocation and is strictly contraindicated after hip replacement or repair.

Accepted Answer

Change the bag and tubing per facility policy (typically every 4-8 hours)
