A client's serum potassium level is 6.8 mEq/L. Which finding requires the nurse's immediate attention?
Answer: Peaked T waves on the ECG
Peaked T waves indicate cardiac membrane instability from hyperkalemia and can progress to lethal dysrhythmias.
Before a paracentesis, which nursing action reduces the client's risk of injury?
Answer: Having the client empty the bladder
Emptying the bladder lowers the risk of accidental bladder puncture during needle insertion.
A client is scheduled for an MRI. Which item must the nurse ensure is removed or addressed?
Answer: Implanted cardiac pacemaker
A pacemaker contains ferromagnetic components and electronics that the strong magnetic field can disrupt, posing serious harm.
Which lab value should the nurse review before a client receives a contrast dye CT scan?
Answer: Serum creatinine
Contrast dye is nephrotoxic, so baseline renal function via creatinine must be assessed to reduce kidney injury risk.
A client on warfarin has an INR of 5.2. Which action does the nurse anticipate?
Answer: Holding the next warfarin dose
An INR of 5.2 is above therapeutic range and increases bleeding risk, so warfarin is held to reduce that risk.
After a liver biopsy, in which position should the nurse place the client to reduce bleeding risk?
Answer: Right side-lying with a pillow against the site
Lying on the right side applies pressure to the biopsy site and helps prevent hemorrhage.
Which client statement before a colonoscopy indicates a need for further teaching?
Answer: "I ate a steak dinner last night."
Eating solid food the night before prevents adequate bowel preparation and increases procedure risk and need to repeat.
