ATI Pathophysiology Final Exam
1. A homeless man was screened for tuberculosis (TB) during a health consultation at a shelter, and the results indicate latent TB. The community health nurse who is liaising with the providers of the shelter would anticipate what component of this man's plan of care?
- A. The man will undergo conservative treatment for TB using adjuvant medications.
- B. The man will be treated for TB using first-line antitubercular drugs.
- C. The man will be monitored closely to determine if treatment is necessary.
- D. The man will be screened again in 10 to 12 weeks to determine if he has developed active TB.
Correct answer: B
Rationale: The correct answer is B. When a patient is diagnosed with latent TB infection, the standard approach involves treating them with first-line antitubercular drugs to prevent the progression to active TB. Adjuvant medications are not typically used for latent TB. Close monitoring without initiating treatment can lead to the development of active TB, so immediate treatment is crucial. Screening the individual again in 10 to 12 weeks does not address the immediate need for treatment of latent TB, which is essential to prevent the progression of the disease.
2. Following cardiothoracic surgery where controlled therapeutic hypothermia was utilized to decrease metabolic demands, the nurse responsible for monitoring this client postoperatively should be assessing for which potential complication related to cold cardioplegia?
- A. Thrombocytopenia
- B. Hypokalemia
- C. Hyperglycemia
- D. Coagulopathy
Correct answer: D
Rationale: Coagulopathy is the correct answer. During therapeutic hypothermia, which lowers the body's temperature to reduce metabolic demands post-surgery, coagulopathy, or impaired blood clotting, is a potential complication due to the effects of cold cardioplegia. Thrombocytopenia (choice A) refers to a low platelet count and is not directly related to cold cardioplegia. Hypokalemia (choice B) is a condition of low potassium levels, and hyperglycemia (choice C) is high blood sugar levels, neither of which are primary complications of cold cardioplegia.
3. A client with chronic obstructive pulmonary disease (COPD) is admitted to the hospital for pneumonia. Which intervention should the nurse prioritize?
- A. Administer bronchodilators as prescribed.
- B. Monitor oxygen saturation levels continuously.
- C. Administer intravenous antibiotics as prescribed.
- D. Provide respiratory therapy treatments as needed.
Correct answer: C
Rationale: Administering IV antibiotics is crucial for treating pneumonia in a client with COPD. Pneumonia is an infection of the lungs that requires prompt antibiotic therapy to prevent complications and improve outcomes. While bronchodilators may help with COPD symptoms, in the case of pneumonia, addressing the infection is the priority. Continuous monitoring of oxygen saturation is important, but administering antibiotics to treat the underlying infection takes precedence. Respiratory therapy treatments can be beneficial, but they are not the initial priority when managing pneumonia in a client with COPD.
4. Which immunoglobulin is the first to appear in response to a new antigen?
- A. IgA
- B. IgG
- C. IgE
- D. IgM
Correct answer: D
Rationale: The correct answer is IgM. IgM is the first immunoglobulin to appear in response to a new antigen. It is produced initially during the primary immune response. IgA is mainly found in mucosal areas and secretions. IgG is produced in a secondary immune response and is the most abundant immunoglobulin in the bloodstream. IgE is involved in allergic reactions and parasitic infections, not the initial response to a new antigen.
5. What is a potential implication of multiple dark bands on the nails?
- A. They are considered a normal variant.
- B. They can be associated with malignant melanoma.
- C. They are indicative of a nail fungus.
- D. They are associated with aging.
Correct answer: B
Rationale: Multiple dark bands on the nails can be a concerning sign of malignant melanoma, a type of skin cancer that can affect the nails. While some nail changes are considered normal variants, dark bands should not be dismissed lightly as they can indicate a serious condition like melanoma. Nail fungus typically presents differently, causing discoloration, thickening, or distortion of the nail without distinct dark bands. Additionally, aging can lead to various nail changes, but dark bands alone are not a common feature of normal aging.
