Quiz Questions Hematologic System Questions
Question 1 of 5
Platelets are manufactured in:
Correct Answer: C
Rationale: Platelets are manufactured in the bone marrow because it is the primary site of hematopoiesis, where all blood cells, including platelets, are produced. The bone marrow contains stem cells that differentiate into various blood cell types, including platelets. The large intestine and small intestine are not involved in blood cell production. The liver plays a role in blood clotting by producing certain proteins, but it does not manufacture platelets. Therefore, the correct answer is C: The bone marrow.
Question 2 of 5
The nurse is caring for a child with sickle cell disease experiencing severe chest pain, fever, a cough, and dyspnea. What is the nurse’s priority action?
Correct Answer: C
Rationale: The correct answer is C: Notify the health care practitioner because chest syndrome is suspected. Chest syndrome is a life-threatening complication in sickle cell disease characterized by acute chest pain, fever, cough, and dyspnea. The priority action is to notify the healthcare provider immediately for further evaluation and treatment. Administering oxygen (choice A) is important but not the priority in this case. Administering pain medication (choice B) can provide some relief but does not address the underlying cause. Notifying the healthcare provider for a suspected stroke (choice D) is not appropriate based on the symptoms described.
Question 3 of 5
A nurse is developing a plan of care for 5-year-old child with a diagnosis of sickle cell anemia and formulates the following nursing diagnoses. The nurse should select which nursing diagnosis as the priority?
Correct Answer: B
Rationale: The correct answer is B: Deficient Fluid Volume. For a child with sickle cell anemia, dehydration can lead to sickling of red blood cells, causing pain crises. Addressing fluid volume deficit is crucial to prevent complications. Activity Intolerance (A) may result from anemia but is secondary to fluid volume deficit. Disabled Family Coping (C) and Imbalanced Nutrition (D) are important but not as urgent as addressing fluid volume deficit to prevent acute complications.
Question 4 of 5
Which action by the parents demonstrates an understanding of the nurse’s teaching with regard to prevention of iron-deficient anemia?
Correct Answer: B
Rationale: The correct answer is B because starting iron-fortified infant cereal at 4 to 6 months of age aligns with the nurse's teaching to prevent iron-deficient anemia. Iron-fortified foods help meet the infant's iron needs, as breastmilk alone may not provide sufficient iron after 4-6 months. Choice A is incorrect because formula not fortified with iron can lead to iron deficiency. Choice C is incorrect because cow's milk is not recommended before 1 year old due to its low iron content and risk of causing intestinal bleeding. Choice D is incorrect because vitamin C actually enhances iron absorption, so limiting it would not prevent anemia.
Question 5 of 5
A client diagnosed with disseminated intravascular coagulation (DIC) is currently bleeding through the gastrointestinal tract. Which prescription does the nurse anticipate for this client?
Correct Answer: C
Rationale: Rationale: In DIC, there is widespread clotting depleting clotting factors and platelets, leading to bleeding. Fresh frozen plasma and platelets are indicated to replenish these factors. Aspirin and Coumadin are anticoagulants and would worsen bleeding. Heparin is also an anticoagulant and not indicated in active bleeding.
