Nursing Elites

1. Which of the following would the nurse see in a client with thrombocytopenia?

• A. A decreased platelet cell count
• B. Decreased white blood cell count
• C. Increased red blood cell count
• D. An increased platelet cell count

Correct answer: A

Rationale: Thrombocytopenia is characterized by a decreased platelet cell count, leading to an increased risk of bleeding. Therefore, the correct answer is A. Choice B, a decreased white blood cell count, is not typically associated with thrombocytopenia. Choice C, an increased red blood cell count, is not a characteristic finding in thrombocytopenia. Choice D, an increased platelet cell count, is the opposite of what is observed in thrombocytopenia.

2. A male patient receiving androgen therapy is concerned about side effects. What adverse effect should the nurse monitor for during this therapy?

• A. Increased risk of liver dysfunction
• B. Increased risk of cardiovascular events
• C. Increased risk of prostate cancer
• D. Increased risk of bone fractures

Correct answer: B

Rationale: The correct answer is B: Increased risk of cardiovascular events. Androgen therapy can lead to an increased risk of cardiovascular events such as heart attack and stroke, especially in older patients. Choice A is incorrect because androgen therapy usually does not significantly increase the risk of liver dysfunction. Choice C is incorrect as androgen therapy does not increase the risk of prostate cancer; in fact, it is sometimes used in the treatment of prostate cancer. Choice D is also incorrect as androgen therapy is more likely to improve bone density and reduce the risk of fractures.

3. A patient is diagnosed with ischemic heart disease. She is prescribed filgrastim (Neupogen). What effect will this medication provide in the treatment of ischemic heart disease?

• A. Increase platelets
• B. Decrease platelets
• C. Promote angiogenesis
• D. Prevent thrombus formation

Correct answer: C

Rationale: Filgrastim (Neupogen) is a medication that promotes the growth of white blood cells. In the context of ischemic heart disease, promoting angiogenesis, the formation of new blood vessels, can improve blood flow to the heart muscle, reducing ischemia and potentially improving cardiac function. Therefore, the correct answer is C. Choices A and B are incorrect because filgrastim does not directly affect platelet levels. Choice D is also incorrect as filgrastim does not prevent thrombus formation.

4. A patient presents with a sudden onset of severe chest pain radiating to his back. His blood pressure is significantly higher in the right arm than in the left arm. Which of the following conditions is most likely?

• A. Acute myocardial infarction
• B. Pulmonary embolism
• C. Aortic dissection
• D. Pericarditis

Correct answer: C

Rationale: The correct answer is C, aortic dissection. Aortic dissection is characterized by sudden, severe chest pain that can radiate to the back. The discrepancy in blood pressure between the arms (higher in the right arm) is known as a 'pulse deficit' and is a classic finding in aortic dissection. This condition involves a tear in the inner layer of the aorta, leading to the abnormal flow of blood within the aortic wall. Acute myocardial infarction (choice A) presents with chest pain but typically does not cause discrepancies in blood pressure between arms. Pulmonary embolism (choice B) usually presents with chest pain and difficulty breathing but does not cause unequal blood pressures in the arms. Pericarditis (choice D) can cause chest pain exacerbated by breathing or lying down, but it does not typically lead to differences in blood pressure between arms.

5. A patient's anemia is described as having erythrocytes that demonstrate anisocytosis. The nurse would recognize the erythrocytes as:

• A. Pale in color
• B. Present in various sizes
• C. Able to assume various shapes
• D. Live only a few days

Correct answer: B

Rationale: The correct answer is B: 'Present in various sizes.' Anisocytosis refers to erythrocytes that are present in various sizes, indicating an abnormality in the uniformity of red blood cell size. Choice A is incorrect because anisocytosis does not refer to the color of erythrocytes. Choice C is incorrect as anisocytosis does not involve the shape of erythrocytes. Choice D is incorrect as anisocytosis does not determine the lifespan of erythrocytes.
