The LPN is reviewing morning labs for a patient on furosemide. Which result requires the most immediate notification to the RN?
Answer: Potassium 2.8 mEq/L
Furosemide causes potassium wasting; a level of 2.8 mEq/L indicates hypokalemia, which can cause life-threatening cardiac arrhythmias.
A patient with chronic kidney disease is on a fluid restriction of 1,200 mL/day. The patient has already consumed 900 mL by noon. How much fluid remains for the rest of the day?
Answer: 300 mL
1,200 mL total minus 900 mL consumed equals 300 mL remaining for the rest of the day.
An LPN notes that a patient's IV site is swollen, cool, and pale with no blood return. These findings are most consistent with:
Answer: Infiltration
Infiltration occurs when IV fluid leaks into surrounding tissue, causing swelling, coolness, pallor, and absent blood return at the site.
Which pain assessment tool is most appropriate for an LPN to use with a non-verbal patient who has dementia?
Answer: PAINAD (Pain Assessment in Advanced Dementia)
The PAINAD scale assesses behavioral indicators of pain (breathing, vocalization, facial expression, body language, consolability) in patients with advanced dementia who cannot self-report.
A patient with a new colostomy expresses embarrassment and states, 'I'll never be able to go out in public again.' The LPN's best initial response is:
Answer: 'Tell me more about what worries you most about going out.'
Therapeutic communication begins with an open-ended statement that invites the patient to express their feelings before offering information or resources.
A patient is in skeletal traction for a femur fracture. Which nursing action is the LPN's priority?
Answer: Assessing neurovascular status of the affected extremity every 2–4 hours
Frequent neurovascular checks (circulation, sensation, movement) detect compartment syndrome or nerve damage, the most serious complications of skeletal traction.
The LPN is educating a patient about pursed-lip breathing. Which outcome best indicates the patient understood the technique?
Answer: 'I inhale through my nose for 2 counts and exhale slowly through pursed lips for 4 counts.'
Pursed-lip breathing involves slow nasal inhalation and prolonged exhalation through pursed lips (ratio approximately 1:2) to reduce air trapping and dyspnea.
