A patient with osteoarthritis is scheduled for a total knee arthroplasty. The nurse identifies that the surgery will be postponed if the patient experiences which condition?

Chronic joint inflammation

Pain

Infection

Immobility

Answer and Explanation

The Correct Answer is C

A. Chronic joint inflammation is a common feature of osteoarthritis, but it does not necessarily preclude surgery. In fact, joint inflammation is often a reason for considering a total knee arthroplasty.
B. Pain is a typical symptom of osteoarthritis, but it is not a reason to postpone surgery. Pain management can be addressed during the perioperative period.
C. Infection is a critical factor that would delay surgery. If the patient has an active infection, particularly in the joint or surrounding tissues, the risk of spreading the infection during surgery is high, and the procedure would need to be postponed until the infection is resolved.
D. Immobility is a concern for postoperative recovery but does not typically delay surgery. Physical therapy and rehabilitation can address immobility after the procedure.

Correct Answer is A

Explanation

A. Applying ice to the affected area is recommended after arthroscopic knee surgery to reduce swelling and pain. Ice helps control inflammation and promotes healing.
B. Bedrest is not typically necessary after arthroscopic knee surgery. Early mobilization is encouraged to prevent complications such as blood clots and to promote recovery.
C. Active range of motion should not be started immediately post-surgery unless specifically instructed by the surgeon. Early movement may be recommended, but it is generally passive range of motion or gentle exercises initially.
D. Keeping the leg in a dependent position could increase swelling. The leg should be elevated to reduce swelling, especially in the first few days after surgery.

A. Hypermagnesemia B. Hypocalcemia C. Dehydration D. Hyperkalemia

Correct Answer is B

Explanation

A. Hypermagnesemia: This condition can cause muscle weakness or lethargy, but it is not typically associated with muscle cramping.
B. Hypocalcemia: Muscle cramping is a common sign of hypocalcemia, which can occur in acute pancreatitis due to the precipitation of calcium in the pancreas or the surrounding tissues. Hypocalcemia leads to neuromuscular irritability, causing muscle spasms and cramping.
C. Dehydration: Dehydration can lead to muscle weakness, but muscle cramping is more commonly associated with electrolyte imbalances like hypocalcemia.
D. Hyperkalemia: While hyperkalemia can cause muscle weakness or even paralysis, it is not typically associated with muscle cramping.
