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 increase in granulocytes in both blood and bone marrow. This finding is commonly seen in conditions such as infections and inflammatory processes. The other choices are incorrect because A describes agranulocytosis, B is a potential cause of granulocytosis, and C typically involves abnormal proliferation of myeloid cells rather than just 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 to document a large area of discoloration from hemorrhage under the skin is ecchymosis. Ecchymosis refers to a bruise caused by the extravasation of blood into the subcutaneous tissues. Pallor (A) is paleness, rubor (B) is redness, and petechiae (C) are tiny, pinpoint-sized red or purple spots on the skin due to bleeding. Ecchymosis is the most appropriate term for describing a large area of discoloration from hemorrhage under the skin as it specifically denotes a bruise resulting from blood leakage into tissues.
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 prevent bacterial contamination and ensure the integrity of the product. Beyond 4 hours, the risk of bacterial growth and contamination increases, leading to potential harm for the patient. Therefore, it is crucial to adhere to this time limit to maintain the safety and effectiveness of the blood product. Summary: - A (1 hour), B (2 hours), and C (3 hours) are incorrect because they do not align with the standard maximum hang time for blood products, which is 4 hours. Adhering to this time limit is essential to prevent deterioration and ensure patient safety.
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 correct answer is C: 7.38. Normal blood pH ranges from 7.35 to 7.45. A pH of 7.38 falls within this range, indicating a slightly alkaline (basic) pH, which is considered normal. Choices A, B, and D are all outside the normal range, indicating acidosis (A and B) or alkalosis (D). Therefore, C is the correct answer as it falls within the normal blood pH 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: Rationale: A 0.9% normal saline solution is the correct choice for blood transfusion because it is isotonic, which closely matches the osmolarity of blood. This helps prevent hemolysis and maintains the integrity of red blood cells during transfusion. Other choices such as B (dextrose 5% and water), C (dextrose 5% and 0.9% normal saline), and D (dextrose 5% and 0.45% normal saline) are incorrect because they do not provide the necessary isotonic environment for safe blood transfusion, risking hemolysis or other complications.
