Pathophysiology Final Exam
1. Which of the following statements indicates more teaching is needed regarding secondary lymph organs? ________is/are a secondary lymph organ.
- A. The spleen
- B. Peyer's patches
- C. Adenoids
- D. The liver
Correct answer: D
Rationale: The correct answer is D, 'The liver.' The liver is not a secondary lymph organ. Secondary lymph organs are primarily involved in the immune response, such as the spleen, Peyer's patches, and adenoids. The spleen filters blood and is essential for immune function. Peyer's patches are located in the small intestine and help protect against pathogens. Adenoids are located in the throat and play a role in immune defense. Therefore, the liver is the incorrect choice as it is not part of the secondary lymph organ system.
2. A patient is hospitalized due to nonadherence to an antitubercular drug treatment. Which of the following is most important for the nurse to do?
- A. Observe the patient taking the medications.
- B. Administer the medications parenterally.
- C. Instruct the family on the medication regimen.
- D. Count the number of tablets in the bottle daily.
Correct answer: A
Rationale: In this scenario, the most crucial action for the nurse to take is to observe the patient taking the medications. This ensures that the patient is actually consuming the prescribed antitubercular drugs, addressing the issue of nonadherence directly. Administering the medications parenterally (intravenously or intramuscularly) is not necessary unless there are specific medical reasons requiring this route of administration. Instructing the family on the medication regimen is important for support but may not directly address the patient's nonadherence. Counting the number of tablets in the bottle daily is not as effective as directly observing the patient taking the medications to ensure compliance.
3. When starting on oral contraceptives, what key point should the nurse emphasize about taking the medication consistently?
- A. Oral contraceptives should be taken at the same time each day to maintain stable hormone levels and prevent pregnancy.
- B. Oral contraceptives can be taken at any time of day, as long as the schedule is consistent.
- C. Oral contraceptives should be taken in the morning to avoid nighttime side effects.
- D. Oral contraceptives are effective immediately upon starting, regardless of timing.
Correct answer: A
Rationale: When starting on oral contraceptives, it is crucial to take them at the same time each day to maintain stable hormone levels and ensure their effectiveness in preventing pregnancy. Choice B is incorrect because consistency in timing is essential to maximize contraceptive efficacy. Choice C is incorrect as there is no evidence that taking oral contraceptives in the morning helps avoid nighttime side effects. Choice D is incorrect because oral contraceptives do not provide immediate effectiveness and require consistent use to prevent pregnancy.
4. Which type of lymphocyte recognizes and eliminates virus-infected cells and cancerous cells?
- A. Neutrophils
- B. Macrophages
- C. Natural killer cells
- D. Langerhans cells
Correct answer: C
Rationale: Natural killer cells are a type of lymphocyte that plays a crucial role in recognizing and eliminating virus-infected cells and cancerous cells. Neutrophils (Choice A) are a type of white blood cell involved in fighting infections, mainly through phagocytosis. Macrophages (Choice B) are another type of white blood cell that engulfs and digests cellular debris and pathogens. Langerhans cells (Choice D) are a type of dendritic cell found in the skin and mucosa, primarily involved in antigen presentation.
5. A college student has a TB test prior to starting the semester. The tuberculin test site is noted with a reddened, raised area. What condition will the student be diagnosed with if the chest radiograph is negative?
- A. Transmission
- B. Primary infection
- C. Latent tuberculosis
- D. Active tuberculosis
Correct answer: C
Rationale: If the chest radiograph is negative despite a positive tuberculin skin test, the student will be diagnosed with latent tuberculosis infection. Latent tuberculosis means the student has the TB bacteria in their body but does not feel sick and cannot spread the disease. Choice A, 'Transmission,' is incorrect as it refers to the spread of TB from person to person. Choice B, 'Primary infection,' is incorrect because primary infection occurs when a person is first infected with the TB bacteria. Choice D, 'Active tuberculosis,' is incorrect as this refers to the active form of the disease where the person feels sick and can spread TB to others.
