Hematological System Questions
Question 1 of 5
A patient is admitted to determine why red blood cells are being quickly destructed in the body. What finding should the nurse associate with this patient's health problem?
Correct Answer: A
Rationale: The correct answer is A: Jaundice. Jaundice is a yellowing of the skin and eyes due to an excess of bilirubin, a byproduct of red blood cell breakdown. In this case, rapid destruction of red blood cells leads to an increased production of bilirubin, causing jaundice. Bleeding (B) is not directly related to red blood cell destruction. Diarrhea (C) and cyanosis (D) are not typically associated with red blood cell destruction.
Question 2 of 5
A patient is prescribed to receive 2 units of packed red blood cells. What approach should the nurse use to ensure that the correct blood will be provided to this patient?
Correct Answer: C
Rationale: Correct Answer: C Rationale: 1. Following the organization's verification process ensures accuracy in blood transfusion. 2. This process involves multiple checks to confirm the correct blood for the patient. 3. Checking the patient's arm band (A) and medical record order (B) are initial steps but may not guarantee accuracy. 4. Assuming correct blood was provided (D) is risky and can lead to serious consequences.
Question 3 of 5
A patient who underwent lymphangiography the day before asks the licensed practical nurse (LPN), “Why does my urine look blue?†What should the LPN respond to this patient's concern?
Correct Answer: D
Rationale: The correct answer is D because lymphangiography involves injecting a dye into the lymphatic system, which can cause the urine to appear blue temporarily. The LPN should reassure the patient that this is a normal and expected side effect of the procedure. Choice A is incorrect as it lacks explanation and may not address the patient's concern. Choice B is unnecessary as there is no urgent need to notify the RN and physician. Choice C is incorrect because blue urine does not necessarily indicate abnormal results, but rather a common side effect of the dye used in the procedure.
Question 4 of 5
A patient has a platelet count of 75,000 /mm³. What action should the nurse take to support this patient?
Correct Answer: A
Rationale: The correct action is to restrict blood draws. With a platelet count of 75,000 /mm³, the patient is at risk for bleeding due to thrombocytopenia. Restricting blood draws helps minimize the risk of bleeding from puncture sites. Placing the patient in protective isolation (B) is unnecessary for low platelet count. Wearing a mask (C) is not directly related to platelet count. Documenting rectal temperatures (D) is not a priority when managing thrombocytopenia.
Question 5 of 5
The nurse assesses a patient with pernicious anemia. Which assessment finding would the nurse expect?
Correct Answer: C
Rationale: The correct answer is C: Numbness of the extremities. Pernicious anemia is caused by a lack of intrinsic factor, leading to vitamin B12 deficiency. This deficiency can result in neurological symptoms such as numbness and tingling in the extremities. Yellow-tinged sclerae (A) are more indicative of jaundice. A shiny smooth tongue (B) is a characteristic finding in glossitis, not specific to pernicious anemia. Gum bleeding and tenderness (D) are more commonly associated with periodontal disease rather than pernicious anemia.
