Anatomy of Hematologic System Questions
Question 1 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 2 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.
Question 3 of 5
A nurse reviews the laboratory data for an older patient. The nurse would be most concerned about which finding?
Correct Answer: D
Rationale: The correct answer is D: White blood cell (WBC) count of 2800/L. A low WBC count (leukopenia) in an older patient can indicate an impaired immune system, making them vulnerable to infections. This is concerning as older adults have a weakened immune response. A: Hematocrit of 35% is within the normal range. B: Hemoglobin of 11.8 g/dL is slightly low but not a major concern as long as it's not significantly lower. C: Platelet count of 400000/L is within the normal range and not typically a cause for concern.
Question 4 of 5
The nurse examines the lymph nodes of a patient during a physical assessment. Which assessment finding would be of most concern to the nurse?
Correct Answer: A
Rationale: The correct answer is A. A 2-cm nontender supraclavicular node is of most concern as supraclavicular nodes are not normally palpable, and their enlargement can indicate underlying malignancy, such as metastatic cancer. B: A 1-cm mobile and nontender axillary node is within normal limits. C: Inability to palpate superficial lymph nodes may be due to factors like obesity or normal variation. D: Firm inguinal nodes in a patient with an infected foot are expected as a local response to infection.
Question 5 of 5
A client is having a bone marrow biopsy today. What action by the nurse takes priority?
Correct Answer: B
Rationale: The correct answer is B: Ensure valid consent is on the chart. This is the priority because the client must provide informed consent before undergoing a bone marrow biopsy. Without valid consent, the procedure cannot proceed ethically or legally. Administering pain medication (choice A) or sedatives (choice D) may be important for the client's comfort but obtaining consent is essential. Having the client shower in the morning (choice C) is not directly related to the immediate safety or success of the biopsy.
