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. A patient with systemic candidiasis has been prescribed flucytosine. The nurse should be aware of the need to administer this drug with which of the following?
- A. Vitamin D and calcium supplements
- B. Fluconazole (Diflucan)
- C. Amphotericin B
- D. Penicillin G
Correct answer: C
Rationale: The correct answer is C: Amphotericin B. When treating systemic candidiasis, Amphotericin B is the drug of choice, not flucytosine. Amphotericin B is an antifungal medication used to treat severe fungal infections like systemic candidiasis. Choices A, B, and D are incorrect because vitamin D and calcium supplements, fluconazole, and penicillin G are not the drugs of choice for treating systemic candidiasis.
3. Which physiologic response is most likely to accompany activation of the parasympathetic nervous system?
- A. Increased heart rate
- B. Increased gastric motility
- C. Pupil dilation
- D. Sweating
Correct answer: B
Rationale: The correct answer is B: Increased gastric motility. The parasympathetic nervous system is known to promote rest and digest functions, which includes increasing gastric motility to aid in digestion. Choices A, C, and D are incorrect as they are more characteristic of the sympathetic nervous system. The sympathetic nervous system is responsible for the fight or flight response, leading to increased heart rate (Choice A), pupil dilation (Choice C), and sweating (Choice D) among other responses.
4. What is the common denominator of all forms of heart failure?
- A. Pulmonary edema
- B. Jugular venous distention
- C. Peripheral edema
- D. Reduced cardiac output
Correct answer: D
Rationale: The correct answer is D: Reduced cardiac output. All forms of heart failure share the common denominator of reduced cardiac output, which leads to inadequate tissue perfusion. Pulmonary edema (choice A) is a consequence of heart failure but not the common denominator. Jugular venous distention (choice B) and peripheral edema (choice C) are signs of heart failure but do not represent the common denominator shared by all forms.
5. A client with a history of rheumatic fever presents with signs of heart failure. What is the likely underlying cause?
- A. Infective endocarditis
- B. Coronary artery disease
- C. Mitral valve stenosis
- D. Aortic regurgitation
Correct answer: C
Rationale: The correct answer is C: Mitral valve stenosis. Rheumatic fever can lead to scarring and thickening of the heart valves, often affecting the mitral valve. This stenosis can impede blood flow from the left atrium to the left ventricle, eventually causing heart failure. Choice A, infective endocarditis, is an infection of the endocardium, the inner lining of the heart chambers and valves, and is not directly related to rheumatic fever. Choice B, coronary artery disease, involves the obstruction of coronary arteries supplying the heart muscle with blood, leading to ischemia and not typically associated with rheumatic fever. Choice D, aortic regurgitation, is the backflow of blood from the aorta to the left ventricle and is not a common consequence of rheumatic fever.
