A nurse is discussing the difference between rheumatoid arthritis (RA) and osteoarthritis with a newly hired nurse. Which of the following information should the nurse include about osteoarthritis?

"Osteoarthritis causes the joints to become red and hot."

"Osteoarthritis is caused by an autoimmune process."

"Osteoarthritis affects other organs in the body."

"Osteoarthritis can impair a joint on a single side of the body."

Answer and Explanation

The Correct Answer is D

A. "Osteoarthritis causes the joints to become red and hot." This is more characteristic of rheumatoid arthritis, which involves inflammation leading to redness and warmth. Osteoarthritis typically causes pain and stiffness without significant redness or heat.

B. "Osteoarthritis is caused by an autoimmune process." Rheumatoid arthritis is an autoimmune disease where the body's immune system attacks its own tissues. Osteoarthritis is a degenerative joint disease caused by wear and tear of the cartilage.

C. "Osteoarthritis affects other organs in the body." Rheumatoid arthritis is a systemic condition that can affect multiple organs. Osteoarthritis is localized to the joints and does not affect other organs.

D. "Osteoarthritis can impair a joint on a single side of the body." Osteoarthritis can affect one joint or joints on one side of the body, such as one knee or one hip, whereas rheumatoid arthritis typically affects joints symmetrically.

Correct Answer is B

Explanation

A. Hypovolemic shock: While disorientation and low SaO2 could be signs of hypovolemic shock, the presence of petechiae is not a typical symptom. Hypovolemic shock is usually associated with blood loss and does not present with petechiae.

B. Fat embolism: Fat embolism syndrome (FES) is a common complication after fractures, especially long bones like the tibia. The classic triad includes respiratory distress, neurological symptoms, and petechiae, making this the most likely diagnosis.

C. Thrombophlebitis: Thrombophlebitis involves inflammation of a vein due to a blood clot, typically presenting with localized pain, swelling, and redness, not petechiae or disorientation.

D. Osteomyelitis: Osteomyelitis is an infection of the bone. Symptoms include pain, fever, and redness over the infected area, but it does not typically present with disorientation, low SaO2, or petechiae.

A. There is numbness and tingling sensations in the surgical limb. B. Surgical pain is a 4 on a scale 0-10. C. The foot on the surgical limb is slightly cooler that the other limb. D. There are +2 pulses and the surgical limb is pink in color.

Correct Answer is A

Explanation

A. There is numbness and tingling sensations in the surgical limb. Numbness and tingling may indicate neurovascular compromise, such as compartment syndrome or nerve damage, requiring immediate medical attention.

B. Surgical pain is a 4 on a scale 0-10. Pain at a level 4 postoperatively is generally manageable and expected. It does not indicate an immediate complication.

C. The foot on the surgical limb is slightly cooler than the other limb. While a slightly cooler foot could be a concern, it is less urgent than numbness and tingling. Monitoring and comparing with other symptoms are necessary.

D. There are +2 pulses and the surgical limb is pink in color. This indicates good circulation and is a positive sign, not requiring immediate reporting.
