Hematologic System Assessment Questions Questions
Question 1 of 5
HIV positive about early manifestations of acquired immune deficiency syndrome (AIDS)- statements to include in the teaching?
Correct Answer: B
Rationale: The correct answer is B because early manifestations of AIDS include persistent fever, swollen glands, diarrhea, weight loss, and fatigue due to the immune system being compromised by HIV. Choice A is incorrect because HIV leads to a decreased, not elevated, white blood cell count. Choice C is incorrect as energy levels typically decline with AIDS progression. Choice D is incorrect as dry and scaly skin is not a common early symptom of AIDS.
Question 2 of 5
What is a rationale that reflects the importance of the nurse asking a patient about their immunization history?
Correct Answer: A
Rationale: The correct answer is A because asking about the patient's immunization history helps assess their immunity against diseases and determine the need for further immunizations, ensuring they are protected from preventable illnesses. This is crucial for providing appropriate care and preventive measures. Choice B is incorrect as assessing dietary habits and nutrient deficiencies is not directly related to immunization history. Choice C is incorrect as genetic predispositions to autoimmune diseases are not typically identified through immunization history. Choice D is incorrect as compliance for preventive care can be determined through other means and is not the primary purpose of asking about immunization history.
Question 3 of 5
What is the most important test for iron stores?
Correct Answer: B
Rationale: The most important test for iron stores is serum ferritin. Ferritin is a protein that stores iron in the body, and its levels directly reflect the amount of iron stored. Therefore, measuring serum ferritin provides the most accurate assessment of iron stores. Serum calcium (choice A) is not a reliable indicator of iron stores. Serum iron (choice C) can fluctuate based on various factors and does not provide a comprehensive picture of iron stores. Choosing "None of the above" (choice D) would be incorrect as serum ferritin is indeed the most important test for iron stores.
Question 4 of 5
Which usually rare cancer is associated with HIV?
Correct Answer: D
Rationale: The correct answer is D: Kaposi's sarcoma. This rare cancer is associated with HIV due to its link with weakened immune systems. HIV compromises the immune system, making individuals more susceptible to developing Kaposi's sarcoma. Astrocytoma, mesothelioma, and penile cancer are not commonly associated with HIV. Kaposi's sarcoma is characterized by skin lesions and can also affect internal organs, making it a distinctive cancer seen in HIV-positive individuals.
Question 5 of 5
A child is diagnosed with sickle cell disease. The parents are unsure of how their child contracted the disease. What is the most appropriate explanation by the nurse?
Correct Answer: D
Rationale: Rationale: 1. Sickle cell disease is an autosomal recessive genetic disorder. 2. Both parents must be carriers (have the trait) to pass on the disease. 3. If both parents have the trait, each child has a 25% chance of inheriting the disease. 4. Therefore, choice D is correct as it explains the genetic basis of sickle cell disease transmission. Summary of Incorrect Choices: A. Incorrect - Both parents need to be carriers for the child to inherit the disease. B. Incorrect - Both parents need to be carriers for the child to inherit the disease. C. Incorrect - If the mother has the disease, the child would have a 50% chance of inheriting it, not 25%.
