An LPN is caring for a patient with a chest tube connected to a water-seal drainage system. The nurse observes continuous bubbling in the water-seal chamber. This finding indicates:
Answer: An air leak in the system or the pleural space
Continuous bubbling in the water-seal chamber indicates an air leak that must be identified and reported to the RN immediately.
A patient asks an LPN to witness their signature on a consent form for surgery. The LPN should:
Answer: Witness only that the patient signed voluntarily, not that informed consent was given
An LPN may witness a patient's signature, attesting only to voluntary signing; obtaining informed consent and explaining risks is the physician's responsibility.
A patient with chronic kidney disease (CKD) stage 4 has a serum potassium of 6.1 mEq/L. Which food should the LPN advise the patient to AVOID?
Answer: Bananas
Bananas are high in potassium and should be avoided by patients with hyperkalemia secondary to CKD.
Which patient is at the HIGHEST risk for developing a deep vein thrombosis (DVT)?
Answer: A 70-year-old patient 3 days post total hip replacement on bedrest
Virchow's triad (stasis, hypercoagulability, endothelial injury) is maximally present in elderly post-orthopedic surgery patients on bedrest.
An LPN is preparing to administer an oral medication and the patient states, 'I've never seen this pill before.' The correct response is:
Answer: Hold the medication and verify the order before administration
Patient concerns about medication should always prompt the nurse to stop and verify the order against the medication administration record before proceeding.
A patient with pneumonia has an oxygen saturation of 91% on room air and is ordered supplemental oxygen. Which delivery device provides the MOST precise oxygen concentration?
Answer: Venturi mask
A Venturi mask delivers a precise, consistent FiO2 regardless of respiratory pattern, making it ideal for patients needing accurate oxygen titration.
An LPN is caring for a patient with a urinary catheter. Which action BEST prevents catheter-associated urinary tract infection (CAUTI)?
Answer: Keeping the drainage bag below bladder level at all times
Keeping the drainage bag below bladder level prevents urine backflow, which is a major contributor to CAUTI.
