Nursing Elites

1. How does influenza immunization produce immunity?

• A. The virus from the vaccine remains in the body until the end of the season
• B. An attenuated virus causes immune system suppression and triggers immunity
• C. The body identifies the virus and develops antibodies against the virus
• D. The vaccine remains in the injection site and produces immune cells

Correct answer: C

Rationale: The correct answer is C. Influenza immunization works by introducing a weakened or inactivated form of the virus into the body, allowing the immune system to recognize it as foreign. This recognition triggers the production of antibodies specific to the virus. Choice A is incorrect as the virus in the vaccine does not remain in the body until the end of the season. Choice B is incorrect as an attenuated virus does not cause immune system suppression but rather stimulates an immune response. Choice D is incorrect because the vaccine does not stay at the injection site but rather prompts a systemic immune response throughout the body.

2. When assessing for potential signs and symptoms of cryptococcosis in a patient with HIV being treated with Amphotericin B, the nurse should prioritize what assessment?

• A. Neurological assessment
• B. Functional assessment
• C. Nutritional assessment
• D. Cardiac assessment

Correct answer: A

Rationale: In a patient with cryptococcosis and HIV, neurological assessment should be prioritized because cryptococcosis commonly affects the central nervous system, leading to symptoms such as headache, confusion, and altered mental status. This assessment is crucial in monitoring for any neurological complications and guiding appropriate interventions. Functional assessment focuses on the patient's ability to perform activities of daily living and is not directly associated with cryptococcosis. Nutritional assessment is important for overall health but is not the priority when assessing for cryptococcosis. Cardiac assessment is not a priority in cryptococcosis as the primary manifestations are related to the central nervous system.

3. When a patient asks the nurse what hypersensitivity is, how should the nurse respond? Hypersensitivity is best defined as:

• A. A reduced immune response found in most pathologic states
• B. A normal immune response to an infectious agent
• C. An excessive or inappropriate response of the immune system to a sensitizing antigen
• D. Antigenic desensitization

Correct answer: C

Rationale: Hypersensitivity is correctly defined as an excessive or inappropriate response of the immune system to a sensitizing antigen. This response leads to tissue damage or other clinical manifestations. Choice A is incorrect as hypersensitivity involves an exaggerated, not a reduced, immune response. Choice B is incorrect because hypersensitivity is not a normal immune response to an infectious agent but rather an exaggerated one. Choice D is incorrect as it refers to desensitization, which is the opposite of hypersensitivity.

4. A 25-year-old woman who works as an air traffic controller presents with facial pain and severe headache. She reports that she sometimes feels the pain in her neck or ear and that it is particularly bad during very busy times at the airport. What is the most likely diagnosis?

• A. Migraine headache
• B. Cluster headache
• C. Temporomandibular joint syndrome
• D. Sinus headache

Correct answer: C

Rationale: The most likely diagnosis for the 25-year-old woman who works as an air traffic controller and presents with facial pain and severe headache that sometimes radiates to her neck or ear, aggravated by stress, is Temporomandibular joint syndrome. This syndrome involves pain in the jaw joint and the muscles controlling jaw movement, which can radiate to the surrounding areas like the neck and ear. Stress and clenching of the jaw commonly exacerbate the symptoms. Migraine headache (choice A) typically presents with other symptoms like nausea, sensitivity to light or sound, and can be triggered by various factors, not just stress. Cluster headache (choice B) is characterized by severe, unilateral pain around the eye with associated autonomic symptoms. Sinus headache (choice D) is usually associated with sinus congestion or infection, presenting with facial pressure or pain, often worsened by bending forward.

5. When teaching a young woman about the use of hormonal contraceptives, a nurse should emphasize that these drugs are most effective when taken:

• A. Immediately after sexual intercourse.
• B. At the same time each day.
• C. Before going to bed at night.
• D. On an empty stomach.

Correct answer: B

Rationale: The correct answer is B: 'At the same time each day.' Hormonal contraceptives should be taken consistently at the same time each day to maintain stable hormone levels, which is crucial for their effectiveness. Taking them at random times can increase the risk of contraceptive failure. Choices A, C, and D are incorrect because taking hormonal contraceptives immediately after sexual intercourse, before going to bed at night, or on an empty stomach does not align with the recommended usage instructions for these drugs.
