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.

Answer and Explanation

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 A

Explanation

Choice A rationale

Exenatide is a medication used to improve blood sugar control in adults with type 2 diabetes. One of the potential side effects of exenatide is pancreatitis, which can cause severe abdominal pain. Therefore, patients should be instructed to notify their healthcare provider if they start having abdominal pain after starting exenatide.

Choice B rationale

Exenatide should be injected within 60 minutes (1 hour) before the morning and evening meal (or before the two main meals of the day, at least 6 hours apart), not 30 minutes before or after a meal. Therefore, this instruction is incorrect.

Choice C rationale

Exenatide does not act in the same way as insulin. While both insulin and exenatide help to control high blood sugar, they work in different ways. Insulin allows sugar in your blood to enter your cells, while exenatide works by increasing the release of insulin when blood sugar levels are high, decreasing the amount of glucose produced and released by the liver, and slowing gastric emptying.

Choice D rationale

There are precautions about taking exenatide with other medications. For example, exenatide may affect the absorption of some orally administered drugs due to its effect on gastric emptying. Therefore, patients should be advised to take oral medications that require rapid absorption at least 1 hour before injecting exenatide.

A. Limit activity for a day or two after returning home. B. Anticipate a stinging feeling during needle insertion. C. Prepare to sit forward with arms propped on a table. D. Expect a persistent cough after the procedure.

Correct Answer is D

Explanation

Choice A rationale

Limiting activity for a day or two after returning home is a correct understanding. After a thoracentesis, it’s recommended to limit activity for a day or two to allow the body to recover.

Choice B rationale

Anticipating a stinging feeling during needle insertion is a correct understanding. The patient will feel a stinging sensation when the local anesthetic is injected.

Choice C rationale

Preparing to sit forward with arms propped on a table is a correct understanding. This position helps to expand the space between the ribs, making it easier for the doctor to access the pleural space.

Choice D rationale

Expecting a persistent cough after the procedure indicates a need for additional education. While a mild cough immediately after the procedure is normal, a persistent cough could indicate a complication such as a pneumothorax.
