Nursing Elites

1. A woman with chronic osteoarthritis is complaining of knee pain. Which pathophysiological process is contributing to her pain?

• A. Inflammation of the synovial membrane.
• B. Degeneration of the cartilage in the joint.
• C. Joint inflammation occurs when chondrocyte injury destroys joint cartilage, producing osteophytes.
• D. Formation of uric acid crystals in the joint space.

Correct answer: C

Rationale: The correct answer is C. In osteoarthritis, the breakdown of cartilage in the joints leads to chondrocyte injury, which results in the destruction of joint cartilage and the production of osteophytes. This process causes joint inflammation and pain. Choice A is incorrect because osteoarthritis primarily involves the articular cartilage rather than the synovial membrane. Choice B is incorrect as it describes the degeneration of cartilage but does not explain the specific pathophysiological process contributing to pain in osteoarthritis. Choice D is incorrect as the formation of uric acid crystals is characteristic of gout, not osteoarthritis.

2. After a CT scan with intravenous contrast medium, a client returns to the room complaining of shortness of breath and itching. Which intervention should the nurse implement?

• A. Call respiratory therapy to administer a breathing treatment.
• B. Send for an emergency tracheostomy set.
• C. Prepare a dose of epinephrine.
• D. Review the client's complete list of allergies.

Correct answer: C

Rationale: Preparing a dose of epinephrine is the correct intervention in this situation as the client is displaying symptoms of an anaphylactic reaction to the contrast medium used during the CT scan. Epinephrine is the first-line treatment for anaphylaxis due to its ability to reverse the symptoms rapidly. Calling respiratory therapy for a breathing treatment (Choice A) may not address the underlying allergic reaction and delay appropriate treatment. Sending for an emergency tracheostomy set (Choice B) is not indicated as the client's symptoms suggest an allergic reaction rather than airway obstruction. Reviewing the client's complete list of allergies (Choice D) is important but would not provide immediate relief for the client's current symptoms; administering epinephrine takes precedence in this situation.

3. Which laboratory results should the nurse anticipate to be abnormal in a child with hemophilia?

• A. Prothrombin time
• B. Bleeding time
• C. Platelet count
• D. Partial thromboplastin time

Correct answer: D

Rationale: In a child with hemophilia, the nurse should anticipate an abnormality in the partial thromboplastin time (PTT) due to the deficiency in clotting factors. Prothrombin time, bleeding time, and platelet count are typically normal in hemophilia. Prothrombin time measures the extrinsic pathway of coagulation and is not affected in hemophilia. Bleeding time assesses platelet function, which is normal in hemophilia as the issue lies with clotting proteins, not platelets. Platelet count is also expected to be normal unless there is another underlying condition affecting platelet production or function.

4. The nurse is caring for a client with a suspected stroke. Which assessment finding is most indicative of a stroke?

• A. Chest pain
• B. Sudden confusion and difficulty speaking
• C. Gradual onset of weakness in the legs
• D. Nausea and vomiting

Correct answer: B

Rationale: The correct answer is B: Sudden confusion and difficulty speaking. These are classic signs of a stroke, indicating a neurological deficit that requires urgent medical attention. Choices A, C, and D are less indicative of a stroke. Chest pain is more commonly associated with cardiac issues, gradual onset of weakness in the legs could be related to other conditions like peripheral neuropathy, and nausea/vomiting may suggest gastrointestinal problems rather than a stroke.

5. A client with hyperthyroidism is prescribed methimazole. Which adverse effect should the nurse monitor for?

• A. Agranulocytosis
• B. Hypoglycemia
• C. Bradycardia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is Agranulocytosis. Methimazole, used to treat hyperthyroidism, can lead to agranulocytosis, a severe decrease in white blood cells. This condition increases the risk of infections and requires immediate medical attention. Hypoglycemia (choice B) is not a common adverse effect of methimazole. Bradycardia (choice C) is unlikely as methimazole tends to have minimal effects on heart rate. Hypercalcemia (choice D) is not associated with methimazole use.
