1. A 52-year-old patient has a new diagnosis of pernicious anemia. The nurse determines that the patient understands the teaching about the disorder when the patient states:
- A. I need to start eating more red meat and liver.
- B. I will stop having a glass of wine with dinner.
- C. I could choose nasal spray rather than injections of vitamin B12.
- D. I will need to take a proton pump inhibitor such as omeprazole (Prilosec).
Correct answer: C
Rationale: The correct answer is C. Pernicious anemia is a condition where the body can't absorb enough vitamin B12. Treatment usually involves lifelong replacement of vitamin B12. In this case, the patient understanding the disorder is correctly demonstrated by choosing nasal spray or injections of vitamin B12 for replacement therapy. Choices A, B, and D are incorrect because increasing red meat/liver intake, stopping wine consumption, or taking a proton pump inhibitor like omeprazole do not address the primary issue of vitamin B12 absorption in pernicious anemia.
2. Which information shown in the table below about a patient who has just arrived in the emergency department is most urgent for the nurse to communicate to the healthcare provider?
- A. Heart rate
- B. Platelet count
- C. Abdominal pain
- D. White blood cell count
Correct answer: B
Rationale: The correct answer is B: Platelet count. The platelet count is severely decreased, indicating a risk for spontaneous bleeding, which is a critical condition requiring immediate attention. While heart rate, abdominal pain, and white blood cell count are important, a severely decreased platelet count poses a more imminent threat to the patient's health and requires urgent communication to the healthcare provider. The nurse should prioritize addressing this potentially life-threatening issue to ensure prompt intervention and management.
3. Which patient should the nurse assign as the roommate for a patient who has aplastic anemia?
- A. A patient with chronic heart failure
- B. A patient who has viral pneumonia
- C. A patient who has right leg cellulitis
- D. A patient with multiple abdominal drains
Correct answer: A
Rationale: The correct answer is A because patients with aplastic anemia are at risk for infection due to low white blood cell production. Assigning a roommate with viral pneumonia (choice B), cellulitis (choice C), or multiple abdominal drains (choice D) could expose the patient with aplastic anemia to potential infectious agents, which could further compromise their health.
4. 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.
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.
