A patient is ordered to receive IV potassium chloride 40 mEq in 100 mL NS over 1 hour. What is the safest administration method?
Answer: Via infusion pump through a peripheral IV
IV potassium must always be administered slowly via an infusion pump because rapid infusion can cause fatal cardiac arrhythmias.
Which assessment finding indicates that a patient with a urinary catheter may have a catheter-associated urinary tract infection (CAUTI)?
Answer: Cloudy, foul-smelling urine with fever
Cloudy, foul-smelling urine accompanied by fever and possibly flank pain or confusion are hallmark signs of a CAUTI.
An LPN is educating a patient about warfarin therapy. Which food should the patient be instructed to consume consistently rather than avoid entirely?
Answer: Leafy green vegetables
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.
A patient with a hip fracture repair is being positioned in bed. Which position is contraindicated?
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.
The LPN notes that a patient's nasogastric (NG) tube feeding bag has been hanging for 9 hours. What action is required?
Answer: Change the bag and tubing per facility policy (typically every 4-8 hours)
Enteral feeding bags and tubing should be changed every 4-8 hours (per facility policy) to prevent bacterial growth and aspiration risk.
Which action by the LPN best demonstrates proper hand hygiene technique according to CDC guidelines?
Answer: Washing hands with soap and water for at least 20 seconds
The CDC recommends washing hands with soap and water for at least 20 seconds, especially when hands are visibly soiled or after caring for a patient with C. difficile.
A patient is in Buck's traction for a femur fracture. The LPN notices the weights are resting on the floor. What is the correct action?
Answer: Elevate the foot of the bed to restore countertraction
The foot of the bed must be elevated so the patient's body weight provides countertraction, allowing the traction weights to hang freely.
