Anatomy of Hematologic System Questions
Question 1 of 5
A laboratory finding of granulocytosis
Correct Answer: D
Rationale: The correct answer is D because granulocytosis refers to an increased number of granulocytes in both blood and bone marrow. This finding is commonly associated with conditions such as infections, inflammation, and certain hematologic disorders. Other choices are incorrect because A describes a condition of granulocytopenia, B is associated with acute bacterial infections but not specific to granulocytosis, and C refers to myeloproliferative disorders which may involve other cell types besides granulocytes.
Question 2 of 5
The nurse is documenting findings after completing data collection with a patient. What term should the nurse use to document a large area of discoloration from hemorrhage under the skin?
Correct Answer: D
Rationale: The correct term for a large area of discoloration from hemorrhage under the skin is "Ecchymosis" (Choice D). Ecchymosis refers to the medical term for a bruise, which is characterized by a large area of skin discoloration caused by bleeding beneath the skin due to trauma or injury. Pallor (Choice A) refers to paleness of the skin due to decreased blood flow or anemia, not discoloration from hemorrhage. Rubor (Choice B) refers to redness of the skin due to increased blood flow, not discoloration from hemorrhage. Petechiae (Choice C) are tiny red or purple spots on the skin caused by broken capillaries, not a large area of discoloration from hemorrhage as described in the question.
Question 3 of 5
The nurse is monitoring a patient receiving a blood product and is concerned that the blood is going to deteriorate before it is complete infused. What is the maximum time that blood can hang during infusion before it begins to deteriorate?
Correct Answer: D
Rationale: The correct answer is D: 4 hours. Blood products typically have a maximum hang time of 4 hours to reduce the risk of bacterial contamination and ensure the integrity of the product. Beyond this time, there is an increased risk of bacterial growth, which can lead to serious infections in the patient. It is crucial to adhere to the recommended hang time to maintain the safety and efficacy of the blood product. Summary of other choices: A: 1 hour - Too short of a time frame for a blood product to be infused, as it would not allow for the complete administration. B: 2 hours - While closer to the correct answer, it still falls short of the recommended 4-hour maximum hang time for blood products. C: 3 hours - Again, this is not the optimal choice as it exceeds the safe hang time for blood products, increasing the risk of contamination and deterioration.
Question 4 of 5
The nurse is reviewing the results of a patient's arterial blood gas analysis. What should the nurse recognize as being a normal blood pH?
Correct Answer: C
Rationale: The normal blood pH range is 7.35-7.45. Choice C (7.38) falls within this range, indicating a normal pH level. Choices A (7.29) and D (7.48) are outside the normal range, indicating acidosis and alkalosis, respectively. Choice B (7.31) is slightly below the normal range, indicating mild acidosis. Therefore, the correct answer is C as it represents a normal blood pH level within the appropriate range.
Question 5 of 5
The nurse is assisting with the preparation of a blood transfusion for a patient. Which type of fluid should the nurse select to transfuse with the blood?
Correct Answer: A
Rationale: The correct answer is A: 0.9% normal saline. When preparing a blood transfusion, it is essential to select a compatible fluid that will not cause hemolysis of the red blood cells. Normal saline is isotonic and compatible with blood, making it the ideal choice. Dextrose solutions can cause hemolysis and should not be used for blood transfusions. Choice B and C contain dextrose, which is not suitable for blood transfusions. Choice D contains a lower concentration of normal saline, which may not be as effective in maintaining the osmotic balance of the blood cells. Therefore, selecting 0.9% normal saline ensures the safety and integrity of the transfused blood.
