1. The nurse assesses a patient with pernicious anemia. Which assessment finding would the nurse expect?
- A. Yellow-tinged sclerae
- B. Shiny, smooth tongue
- C. Numbness of the extremities
- D. Gum bleeding and tenderness
Correct answer: C
Rationale: The correct answer is C: Numbness of the extremities. Numbness of the extremities is a common finding in patients with pernicious anemia, which is caused by cobalamin (vitamin B12) deficiency. This deficiency affects the peripheral nervous system, leading to neurological symptoms like numbness and tingling in the extremities. Choices A, B, and D are incorrect: Yellow-tinged sclerae is more indicative of jaundice or liver dysfunction, a shiny smooth tongue is seen in conditions like glossitis, and gum bleeding and tenderness are associated with periodontal disease or vitamin C deficiency, not pernicious anemia.
2. The complete blood count (CBC) indicates that a patient is thrombocytopenic. Which action should the nurse include in the plan of care?
- A. Avoid intramuscular injections.
- B. Encourage increased oral fluids.
- C. Check temperature every 4 hours.
- D. Increase intake of iron-rich foods.
Correct answer: A
Rationale: The correct action to include in the plan of care for a thrombocytopenic patient is to avoid intramuscular injections. Thrombocytopenia is a condition characterized by a decreased number of platelets, which are essential for blood clotting. Intramuscular injections can pose a risk of bleeding in patients with low platelet counts. Encouraging increased oral fluids (choice B) is beneficial for hydration but does not directly address the risk of bleeding associated with thrombocytopenia. Checking temperature every 4 hours (choice C) is important for monitoring infection but does not specifically address the risk of bleeding. Increasing intake of iron-rich foods (choice D) is more related to addressing anemia, not the primary concern of bleeding in thrombocytopenia.
3. A patient who is receiving methotrexate for severe rheumatoid arthritis develops a megaloblastic anemia. The nurse will anticipate teaching the patient about increasing oral intake of
- A. iron.
- B. folic acid.
- C. cobalamin (vitamin B12).
- D. ascorbic acid (vitamin C).
Correct answer: C
Rationale: The correct answer is C: cobalamin (vitamin B12). Methotrexate can lead to a deficiency in cobalamin, resulting in megaloblastic anemia. Therefore, increasing the oral intake of cobalamin is essential to address this deficiency. Choice A, iron, is incorrect because megaloblastic anemia caused by methotrexate is not typically due to iron deficiency. Choice B, folic acid, is also incorrect as methotrexate does not directly cause folic acid deficiency. Choice D, ascorbic acid (vitamin C), is incorrect as it is not directly related to megaloblastic anemia caused by methotrexate; instead, cobalamin is the key vitamin that needs attention.
4. The health care provider orders a liver and spleen scan for a patient who has been in a motor vehicle crash. Which action should the nurse take before this procedure?
- A. Check for any iodine allergy.
- B. Insert a large-bore IV catheter.
- C. Administer prescribed sedatives.
- D. Assist the patient to a flat position.
Correct answer: D
Rationale: Before a liver and spleen scan, it is essential to assist the patient to a flat position. This position helps obtain clear images of the liver and spleen. Checking for iodine allergy (Choice A) is more relevant for procedures involving contrast dye, not a liver and spleen scan. Inserting a large-bore IV catheter (Choice B) may not be necessary for this specific procedure. Administering sedatives (Choice C) is not typically required for a liver and spleen scan, as the patient needs to remain still during the procedure.
5. The nurse is reviewing laboratory results and notes a patient's activated partial thromboplastin time (aPTT) level of 28 seconds. The nurse should notify the health care provider in anticipation of adjusting which medication?
- A. Aspirin
- B. Heparin
- C. Warfarin
- D. Erythropoietin
Correct answer: B
Rationale: The correct answer is B: Heparin. An activated partial thromboplastin time (aPTT) level of 28 seconds indicates a prolonged time, which is associated with heparin administration. Heparin is an anticoagulant medication that affects the intrinsic pathway of the coagulation cascade, leading to an increased aPTT. Aspirin (choice A) affects platelet aggregation and does not directly impact aPTT. Warfarin (choice C) affects the extrinsic pathway of the coagulation cascade and is monitored using the international normalized ratio (INR), not aPTT. Erythropoietin (choice D) is not related to coagulation parameters.
