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.

Correct Answer: A

Rationale: The correct answer is A. Gout is characterized by the deposition of uric acid crystals in the synovial fluid of joints, which triggers inflammation and pain. This process is known as crystal-induced arthritis. Choice B is incorrect as gout does not involve degeneration of joint cartilage. Choice C is incorrect as gout is not caused by an infection of the joint space. Choice D is incorrect as gout does not result from increased synovial fluid but rather from the deposition of uric acid crystals.

Correct Answer: B

Rationale: The correct answer is B, Calcium gluconate. In hyperkalemia, where potassium levels are elevated, calcium gluconate is administered to stabilize the myocardial cell membrane and protect the heart from potential arrhythmias. Potassium chloride (choice A) would worsen the condition by further increasing potassium levels. Magnesium sulfate (choice C) is not the primary treatment for hyperkalemia. Sodium bicarbonate (choice D) is used in metabolic acidosis, not specifically for hyperkalemia.

Correct Answer: D

Rationale: The most important instruction for the nurse to include in the discharge teaching for a client with COPD receiving home oxygen therapy is to ensure the oxygen tank is stored in a secure upright position. This is crucial to prevent accidents such as leaks or falls that can lead to serious injury or damage. Choice A is incorrect as increasing the oxygen flow rate during physical activity without a healthcare provider's guidance can be harmful. Choice B is incorrect as smoking near an oxygen source can cause a fire hazard. Choice C is incorrect as petroleum jelly is flammable and should not be used around oxygen due to the risk of combustion.

Correct Answer: B

Rationale: In clients with COPD, oxygen therapy can lead to a decrease in the respiratory drive caused by the removal of the hypoxic drive. This can result in carbon dioxide retention, leading to a decreased level of consciousness. Options A, C, and D are incorrect because an increased respiratory rate is typically a sign of hypoxia, improved oxygen saturation is a positive response to oxygen therapy, and complaints of dry mouth are not directly related to oxygen therapy complications in this scenario.
