Assessment of Hematologic System NCLEX Questions Questions
Question 1 of 5
In irritable bowel syndrome antibiotics are:
Correct Answer: C
Rationale: Rationale: Antibiotics are ineffective in treating irritable bowel syndrome because IBS is not caused by bacterial infections. IBS is a functional disorder of the digestive system. Antibiotics do not target the underlying causes of IBS such as altered gut motility or visceral hypersensitivity. Therefore, using antibiotics to treat IBS would not address the root of the problem and would be ineffective. Other choices are incorrect because antibiotics are not the primary treatment for IBS, they are not used for pain relief in IBS, and there is no age restriction for prescribing antibiotics in IBS treatment.
Question 2 of 5
When caring for the child with leukemia who is at risk for bleeding, which of the following measures should be avoided?
Correct Answer: D
Rationale: The correct answer is D: Performing a rectal examination. This should be avoided in a child with leukemia at risk for bleeding because it can increase the risk of rectal trauma and bleeding. Stool softeners (choice A) are appropriate to prevent constipation and straining. Frequent position changes (choice B) help prevent pressure ulcers. Visits with friends and siblings (choice C) are important for the child's emotional well-being.
Question 3 of 5
A client with disseminated intravascular coagulation (DIC) is anxious and has decreased oxygen saturation. Which is the priority nursing diagnosis for this client?
Correct Answer: B
Rationale: The priority nursing diagnosis for a client with DIC experiencing decreased oxygen saturation is Impaired Gas Exchange (B). This is because impaired gas exchange directly affects oxygenation, which is crucial for tissue perfusion and overall patient well-being. Addressing gas exchange will help improve oxygen saturation levels and prevent further complications. Pain (A) is important but not the priority in this case. Ineffective Tissue Perfusion (C) is related but secondary to impaired gas exchange. Anxiety (D) is also important but addressing oxygenation takes precedence for immediate patient safety.
Question 4 of 5
A child diagnosed with a Wilms tumor is prescribed chemotherapy. Which laboratory test will the nurse monitor prior to administering the chemotherapy to determine the child’s infection-fighting capability?
Correct Answer: C
Rationale: The correct answer is C: Absolute neutrophil count (ANC). Neutrophils are a type of white blood cell that plays a crucial role in fighting infections. Chemotherapy can suppress the bone marrow, leading to a decrease in neutrophil count, putting the child at risk for infections. Monitoring ANC before chemotherapy helps determine the child's infection-fighting capability. A: Hemoglobin - Measures oxygen-carrying capacity of red blood cells, not directly related to infection-fighting capability. B: Red-blood-cell count - Measures the number of red blood cells, not directly related to infection-fighting capability. D: Platelets - Important for blood clotting, not directly related to infection-fighting capability.
Question 5 of 5
A child is diagnosed with rhabdomyosarcoma. Which nursing intervention is most appropriate for this child?
Correct Answer: B
Rationale: The correct answer is B: Monitor for hematuria. Rhabdomyosarcoma is a type of cancer that originates from muscle tissue and can potentially lead to bleeding in the urine (hematuria). Monitoring for hematuria is crucial to assess the child's condition and detect any signs of complications. A: Positioning the child with the head elevated is not directly related to managing rhabdomyosarcoma. C: Demonstrating the use of a conformer is not relevant to the immediate nursing care for rhabdomyosarcoma. D: Administering oxygen may be necessary in some cases, but monitoring for hematuria is more specific and directly related to the potential complications of rhabdomyosarcoma.
