ATI Pathophysiology
1. A male patient is receiving androgen therapy for the treatment of hypogonadism. What adverse effect should the nurse monitor for during this treatment?
- A. Liver dysfunction
- B. Kidney dysfunction
- C. Heart failure
- D. Pulmonary embolism
Correct answer: A
Rationale: The correct adverse effect to monitor for during androgen therapy for hypogonadism is liver dysfunction. Androgen therapy can lead to hepatotoxicity, so monitoring liver function tests is crucial during treatment. Kidney dysfunction (Choice B), heart failure (Choice C), and pulmonary embolism (Choice D) are not commonly associated with androgen therapy and are less likely adverse effects compared to liver dysfunction.
2. What is a common trigger for acute bronchospasm in asthma?
- A. Infection
- B. Allergic reaction
- C. Excessive exercise
- D. High altitude
Correct answer: B
Rationale: An allergic reaction is a common trigger for acute bronchospasm in asthma patients. When individuals with asthma come in contact with allergens like pollen, dust mites, or pet dander, it can lead to an allergic reaction that triggers bronchospasm. Infections, excessive exercise, and high altitudes can exacerbate asthma symptoms, but they are not the most common trigger for acute bronchospasm in asthma patients.
3. Multiple sclerosis manifests as asymmetrical and in different parts of the body because:
- A. Autoreactive lymphocytes are causing diffuse patchy damage to the myelin sheath in the central nervous system.
- B. Acetylcholine receptors are destroyed by immunoglobulin G.
- C. Autoreactive T lymphocytes cause progressive loss of neurons in the substantia nigra.
- D. Cortical motor cells degenerate.
Correct answer: A
Rationale: The correct answer is A. Multiple sclerosis is characterized by the immune system attacking the myelin sheath in the central nervous system. This attack leads to patchy damage on the myelin sheath, resulting in asymmetrical neurological symptoms. Choices B, C, and D are incorrect because they do not accurately describe the pathophysiology of multiple sclerosis. In multiple sclerosis, it is the autoreactive lymphocytes that target and damage the myelin sheath, not acetylcholine receptors, T lymphocytes, or cortical motor cells.
4. Which of the following tests is recommended for lung cancer screening?
- A. Chest X-ray
- B. Pulmonary function test
- C. Computed tomography (CT) scan
- D. Magnetic resonance imaging
Correct answer: Computed tomography (CT) scan
Rationale: The correct answer is Computed tomography (CT) scan. When screening for lung cancer, CT scans are recommended over chest X-rays due to their higher sensitivity in detecting lung nodules and early-stage cancers. Pulmonary function tests are not used for screening lung cancer but rather to assess lung function. Magnetic resonance imaging is not the preferred imaging modality for routine lung cancer screening, as CT scans are more commonly used.
5. How should rifampin most likely be administered to a patient diagnosed with tuberculosis?
- A. Orally, with food
- B. Orally, on an empty stomach
- C. Intramuscularly
- D. Intravenously, as a bolus
Correct answer: A
Rationale: Rifampin is typically administered orally, and it is recommended to be taken with food to enhance its absorption and reduce gastrointestinal side effects. Administering rifampin intramuscularly or intravenously is not the standard route of administration for this medication used in tuberculosis treatment.
