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. A client with a history of seizures is prescribed phenytoin. Which instruction should the nurse include in the discharge teaching?

• A. Report any signs of a sore throat or fever immediately
• B. Take the medication with antacids to reduce stomach upset
• C. Discontinue the medication if you feel drowsy
• D. Increase the dosage if you experience an aura

Correct answer: A

Rationale: The correct answer is A: 'Report any signs of a sore throat or fever immediately.' Phenytoin can cause blood dyscrasias, which can manifest as a sore throat or fever. These symptoms could indicate a serious side effect that requires immediate medical attention. Choice B is incorrect because phenytoin should not be taken with antacids as they can decrease its absorption. Choice C is incorrect because discontinuing phenytoin abruptly can lead to rebound seizures; drowsiness is a common side effect that may improve with time. Choice D is incorrect because adjusting the dosage of phenytoin should only be done under healthcare provider supervision, not based on experiencing an aura.

3. A 2-year-old child with laryngotracheobronchitis (LTB) is fussy and restless in the oxygen tent. The oxygen level in the tent is 25%, and blood gases are normal. What would be the correct action by the nurse?

• A. Restrain the child in the tent and notify the health care provider.
• B. Increase the oxygen concentration in the tent.
• C. Take the child out of the tent and into the playroom.
• D. Ask the mother for help in comforting the child.

Correct answer: B

Rationale: The child with LTB should be placed in the mist tent with 30% oxygen. Restlessness is caused by poor oxygenation. The child should not be taken out of the oxygenated tent. While the mother could be asked to help comfort the child, and the health care provider may be notified, the priority is to set the oxygen at the correct level.

4. Which nursing diagnosis should be selected for a client who is receiving thrombolytic infusions for treatment of an acute myocardial infarction?

• A. Risk for infection related to thrombolysis.
• B. Risk for fluid volume deficit related to thrombolysis.
• C. Risk for impaired skin integrity related to thrombolysis.
• D. Risk for injury related to effects of thrombolysis.

Correct answer: D

Rationale: Thrombolytic therapy increases the risk of bleeding, not infection, fluid volume deficit, or impaired skin integrity. The most significant concern with thrombolytic therapy is the potential for bleeding complications, which can lead to various injuries. Therefore, 'Risk for injury related to effects of thrombolysis' is the most appropriate nursing diagnosis in this scenario. Choices A, B, and C are incorrect as they do not directly correlate with the primary risk associated with thrombolytic therapy.

5. How are type IV hypersensitivity reactions different from all other types (I, II, or III) of hypersensitivity reactions?

• A. They involve antigen-antibody complexes.
• B. They are mediated by T cells and do not involve antibodies.
• C. They result in immediate allergic reactions.
• D. They are the least severe form of hypersensitivity.

Correct answer: B

Rationale: Type IV hypersensitivity reactions are mediated by T cells and cytokine release, leading to delayed reactions, unlike types I, II, and III, which involve antibodies. Choice A is incorrect because type IV reactions do not involve antigen-antibody complexes. Choice C is incorrect as type IV reactions do not result in immediate allergic reactions. Choice D is incorrect as type IV reactions are not the least severe form of hypersensitivity; in fact, they are known to cause significant tissue damage and inflammation.
