An elderly patient with osteoarthritis is experiencing increased pain and stiffness in their right knee.
What pathological condition should the nurse identify as the cause of these symptoms?
Degradation of joint cartilage.
A systemic inflammatory response.
An infectious process in the synovial fluid.
A decrease in bone mineral density.
The Correct Answer is A
Choice A rationale
Osteoarthritis is a joint disease in which the tissues in the joint, including the cartilage, break down over time. The degradation of joint cartilage is the primary pathological condition that leads to the symptoms of osteoarthritis, such as increased pain and stiffness.
Choice B rationale
A systemic inflammatory response is not the primary cause of osteoarthritis. While inflammation can occur in the affected joint, osteoarthritis is not a systemic inflammatory disease like rheumatoid arthritis.
Choice C rationale
An infectious process in the synovial fluid is not typically associated with osteoarthritis. Infections can lead to a different type of arthritis known as septic arthritis.
Choice D rationale
A decrease in bone mineral density is associated with osteoporosis, not osteoarthritis. In osteoarthritis, the issue is primarily with the degradation of cartilage, not a loss of bone density.

Correct Answer is C
Explanation
Choice A rationale
A thick, dry, and dark area on the heels could indicate a more advanced stage of a pressure injury, not the earliest indication.
Choice B rationale
Broken skin without evidence of undermining could also indicate a more advanced stage of a pressure injury.
Choice C rationale
A defined area of persistent redness over a bony prominence is often the earliest sign of a developing pressure injury. This is because these areas are more susceptible to pressure and have less padding to protect them.
Choice D rationale
A superficial sacral pressure injury with defined margins is a more advanced stage of a pressure injury.
Correct Answer is {"A":{"answers":"A"},"B":{"answers":"A"},"C":{"answers":"A"},"D":{"answers":"A"}}
Explanation
The findings suggest that the client’s condition has improved.
Choice A rationale
A total blood loss of 800 mL is a significant amount, but it is within the normal range for blood loss during and after childbirth. Therefore, this does not necessarily put the client at risk for hypovolemia.
Choice B rationale
A fundus that is firm and at the level of the umbilicus indicates that the uterus is contracting properly after childbirth, which helps to prevent excessive bleeding.
Choice C rationale
The expulsion of multiple large clots could indicate that the body is effectively clotting blood, which can prevent excessive bleeding.
Choice D rationale
A blood pressure of 110/80 mm Hg, a heart rate of 66 beats/minute, and an oxygen saturation of 98% on room air are all within normal ranges, indicating that the client is stable and not at risk for hypovolemia.
