Nursing Elites

1. What is the primary cause of angina?

• A. Increased oxygen demand by the heart
• B. Obstruction of the coronary arteries
• C. Lack of oxygen in the lungs
• D. Decreased blood supply to the liver

Correct answer: B

Rationale: The correct answer is B: Obstruction of the coronary arteries. Angina is primarily caused by a reduced blood flow to the heart due to blockages or narrowing in the coronary arteries. Choice A is incorrect because while increased oxygen demand can contribute to angina symptoms, it is not the primary cause. Choice C is incorrect as angina is not caused by a lack of oxygen in the lungs. Choice D is also incorrect as angina is not related to decreased blood supply to the liver.

2. A patient is diagnosed with type 2 diabetes mellitus. Which of the following is a common initial treatment strategy?

• A. Insulin therapy
• B. Lifestyle modification and metformin
• C. Sulfonylureas
• D. Thiazolidinediones

Correct answer: B

Rationale: The correct answer is B: Lifestyle modification and metformin. When managing type 2 diabetes mellitus, initial treatment often involves lifestyle changes such as adopting a healthy diet and increasing physical activity, along with the oral medication metformin. Insulin therapy (choice A) is usually reserved for cases where lifestyle changes and oral medications are not sufficient to control blood sugar levels. Sulfonylureas (choice C) and thiazolidinediones (choice D) are also oral medications used in diabetes management, but they are not typically recommended as first-line treatments due to various side effects and considerations in type 2 diabetes management.

3. A client arrives with symptoms of stroke. What should the nurse assess first?

• A. Level of consciousness
• B. Blood pressure
• C. Pupil reaction
• D. Heart rate

Correct answer: A

Rationale: Assessing the level of consciousness is a critical first step in evaluating a potential stroke. Changes in the level of consciousness can indicate the severity and location of brain damage, helping to guide immediate interventions. Assessing blood pressure, pupil reaction, and heart rate are also important aspects of the assessment in a suspected stroke patient. However, the priority is to quickly determine the client's level of consciousness to assess their neurological status.

4. A patient has been diagnosed with a fungal infection and is to be treated with itraconazole (Sporanox). Prior to administration, the nurse notes that the patient is taking carbamazepine (Tegretol) for a seizure disorder. Based on this medication regime, which of the following will be true regarding the medications?

• A. The serum level of carbamazepine will be increased.
• B. The patient's carbamazepine should be discontinued.
• C. The patient's antiseizure medication should be changed.
• D. The patient will require a higher dosage of itraconazole (Sporanox).

Correct answer: A

Rationale: When itraconazole is administered with carbamazepine, itraconazole may increase the serum levels of carbamazepine, potentially leading to toxicity. Therefore, choice A is correct. Discontinuing carbamazepine (choice B) or changing the antiseizure medication (choice C) is not necessary unless advised by a healthcare provider. Choice D, requiring a higher dosage of itraconazole, is not accurate in this scenario.

5. Innate resistance or immunity:

• A. Involves 'memory'
• B. Is a development of an individual's later years
• C. Is a relatively slow and specific process
• D. Depends on physical, mechanical, and biochemical barriers

Correct answer: D

Rationale: Innate resistance or immunity relies on the body's natural defenses like physical, mechanical, and biochemical barriers. These barriers act as the first line of defense against pathogens and do not involve memory (choice A). Innate immunity is present from birth and does not develop over an individual's later years (choice B). Additionally, innate immunity is a rapid and nonspecific process, not a slow and specific one (choice C). Therefore, the correct answer is D.
