ATI Pathophysiology Exam 1
1. What is the major effect of filgrastim (Neupogen) in a patient with chronic renal failure?
- A. Decreases neutropenia related to chemotherapy
- B. Decreases white blood cells related to infection
- C. Decreases growth of blood vessels due to ischemia
- D. Decreases platelet count related to bleeding
Correct answer: A
Rationale: The major effect of filgrastim (Neupogen) is to stimulate the production of neutrophils, thereby decreasing neutropenia in patients undergoing chemotherapy. This medication helps the bone marrow produce more white blood cells, specifically neutrophils, to reduce the risk of infections associated with low neutrophil counts. Choices B, C, and D are incorrect because filgrastim does not decrease white blood cells related to infection, growth of blood vessels, or platelet count related to bleeding.
2. What is the most common cause of cancer-related deaths in both men and women?
- A. Lung cancer
- B. Breast cancer
- C. Colorectal cancer
- D. Prostate cancer
Correct answer: A
Rationale: Lung cancer is the leading cause of cancer-related deaths in both men and women globally. It is strongly associated with smoking and exposure to environmental toxins. Breast cancer (choice B) primarily affects women, while colorectal cancer (choice C) and prostate cancer (choice D) are more gender-specific. Colorectal cancer is more common in both men and women but not the leading cause of cancer-related deaths.
3. Which symptoms are typical of asthma?
- A. Chest pain; cough
- B. Diarrhea; wheezing
- C. Wheezing; dyspnea
- D. Tachypnea; constipation
Correct answer: C
Rationale: The correct answer is C: Wheezing and dyspnea are typical symptoms of asthma. Wheezing refers to a high-pitched whistling sound while breathing, and dyspnea is shortness of breath. These symptoms are classic signs of airway obstruction and inflammation seen in asthma. Choice A is incorrect as chest pain is not a typical symptom of asthma, though coughing can occur. Choice B is incorrect as diarrhea is not associated with asthma, while wheezing is a common symptom. Choice D is incorrect as tachypnea (rapid breathing) can occur in asthma, but constipation is not a typical symptom.
4. Which of the following conditions is associated with a positive Homan's sign?
- A. Deep vein thrombosis
- B. Peripheral artery disease
- C. Varicose veins
- D. Lymphedema
Correct answer: A
Rationale: A positive Homan's sign is indicative of deep vein thrombosis. This sign is elicited by dorsiflexing the foot of a patient with the knee slightly flexed, resulting in calf pain. Peripheral artery disease (choice B) is associated with decreased blood flow to the extremities, but it does not produce a positive Homan's sign. Varicose veins (choice C) are enlarged, twisted veins that are typically not related to Homan's sign. Lymphedema (choice D) is swelling caused by a lymphatic system blockage or dysfunction and is not linked to Homan's sign.
5. A patient is prescribed tadalafil (Cialis) for erectile dysfunction. What specific contraindication should the nurse discuss with the patient?
- A. History of hypertension
- B. Use of nitrates
- C. Use of antihypertensive medications
- D. History of peptic ulcer disease
Correct answer: B
Rationale: The correct answer is B: 'Use of nitrates.' Tadalafil (Cialis) is contraindicated in patients taking nitrates due to the risk of severe hypotension. Nitrates and Cialis both cause vasodilation, which can lead to a dangerous drop in blood pressure when used together. Choices A, C, and D are incorrect because a history of hypertension, use of antihypertensive medications, and a history of peptic ulcer disease are not specific contraindications for tadalafil use.
