Question 1 of 5
A nurse is reviewing laboratory data on a client who is recovering from surgery.ExhibitsDrag 1 condition and 1 client finding to fill in each blank in the following sentence.The client is at risk for developing ----------due to-----------------
Correct Answer: A,B
Rationale: The client’s postoperative potassium level of 3.0 mEq/L (below 3.5-5 mEq/L) indicates hypokalemia, which disrupts cardiac electrical conductivity, increasing arrhythmia risk. Potassium is vital for heart repolarization, and low levels can prolong the QT interval, leading to potential cardiac events.

Question 2 of 5
A nurse is caring for a postoperative patient. Which finding will alert the nurse to a potential wound dehiscence?
Correct Answer: B
Rationale: A patient reporting 'something has given way' is a significant indicator of potential wound dehiscence, as it suggests partial or complete separation of surgical wound layers. Chronic drainage may indicate infection or poor healing, purulent drainage suggests infection, and protrusion of organs indicates evisceration, a later stage of dehiscence, not an early warning sign.
Question 3 of 5
A nurse is caring for a client who is using a patient-controlled analgesia (PCA) pump for postoperative pain management. The nurse enters the room to find the client asleep and his partner pressing the button to dispense another dose. Which of the following responses should the nurse make?
Correct Answer: D
Rationale: Only the client should use the PCA pump to ensure medication is administered based on their pain, preventing overmedication. Other responses either encourage misuse or fail to educate properly.
