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 B

Explanation

A. Right hemiparesis, or weakness on the right side of the body, is typically associated with a stroke involving the left hemisphere of the brain, as the left side of the brain controls motor function on the right side of the body.
B. Inability to recognize family members, or prosopagnosia, is a common result of right hemisphere strokes. The right hemisphere is responsible for spatial awareness and recognition of faces, so damage to this area can impair the ability to recognize familiar people.
C. Aphasia is a language disorder commonly associated with strokes affecting the left hemisphere, particularly the areas responsible for speech production and comprehension, such as Broca's area and Wernicke's area.
D. Difficulty reading, or alexia, is more commonly associated with damage to the left hemisphere, specifically the areas related to language processing, rather than the right hemisphere.

A. WBC count 20,000/mm3 B. Potassium 3.8 mEq/L C. Hematocrit 40% D. Creatinine 0.9 mg/dL

Correct Answer is A

Explanation

A. A WBC count of 20,000/mm3 is elevated, which suggests the presence of infection or inflammation. This is concerning and should be reported to the surgeon, as an infection or other underlying issue could delay or contraindicate surgery.
B. A potassium level of 3.8 mEq/L is within the normal range (3.5–5.0 mEq/L). It does not require immediate intervention and is not a concern for surgery.
C. A hematocrit of 40% is within the normal range for an adult female (typically 36–48%), so it does not require intervention.
D. A creatinine level of 0.9 mg/dL is normal for most adults (0.6–1.2 mg/dL), suggesting normal kidney function and not requiring any intervention.
