Anatomy of Hematologic System Questions
Question 1 of 5
A nurse is monitoring a client following ferrous sulfate administration. The nurse should monitor the client for which of the following adverse effects?
Correct Answer: D
Rationale: The correct answer is D: Constipation. Ferrous sulfate, an iron supplement, commonly causes constipation due to its effects on the digestive system. Iron slows down bowel movements, leading to constipation. Monitoring for constipation is crucial to ensure the client's comfort and prevent complications. Phlebitis (choice A) is not a common adverse effect of ferrous sulfate administration. Dark, tarry stools (choice B) can indicate gastrointestinal bleeding but are not directly related to iron supplementation. Orange-colored stools (choice C) are not a typical side effect of ferrous sulfate and are more commonly associated with certain foods or medications.
Question 2 of 5
A nurse is reviewing the medication record of a client who is receiving alteplase following an acute myocardial infarction (MI). Which of the following medications should the nurse expect the client to be taking in addition to the alteplase?
Correct Answer: D
Rationale: The correct answer is D: Heparin. Following an acute MI, a client receiving alteplase may also be prescribed heparin to prevent re-thrombosis and further clot formation. Alteplase is a thrombolytic agent that works by breaking down clots, while heparin is an anticoagulant that helps prevent new clots from forming. Protamine (choice A) is used to reverse the effects of heparin, not typically administered alongside alteplase. Desmopressin (choice B) is used for conditions like diabetes insipidus, unrelated to MI treatment. Ferrous sulfate (choice C) is an iron supplement, not indicated in this scenario.
Question 3 of 5
A nurse is caring for a client who is experiencing an acute ischemic cerebrovascular event due to a thrombus in a cerebral vessel. Which of the following drugs should the nurse expect to administer?
Correct Answer: A
Rationale: The correct answer is A: Alteplase. Alteplase is a thrombolytic agent used to dissolve blood clots and restore blood flow in acute ischemic stroke. It is crucial to administer within a specific time frame for the best outcome. Aspirin (B) and Clopidogrel (C) are antiplatelet agents that prevent further clot formation but are not used for immediate clot dissolution in acute ischemic stroke. Heparin (D) is an anticoagulant that prevents clot formation and is not typically used as the initial treatment for acute ischemic stroke.
Question 4 of 5
During haemostasis, prostacyclin
Correct Answer: B
Rationale: Prostacyclin is a vasodilator, which means it causes blood vessels to widen, leading to decreased blood pressure and increased blood flow. During haemostasis, this vasodilation helps in maintaining blood flow and preventing platelet aggregation in the damaged area. Option A is incorrect because prostacyclin does not cleave prothrombin into thrombin. Option C is incorrect as prostacyclin inhibits platelet aggregation. Option D is incorrect because prostacyclin does not directly activate fibrinolysis. In summary, the correct answer is B because prostacyclin's vasodilation function plays a crucial role in haemostasis by preventing excessive clot formation and maintaining blood flow.
Question 5 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.
