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.

A healthcare provider reviews the laboratory data for an older patient. The healthcare provider would be most concerned about which finding?
- A. Hematocrit of 35%
- B. Hemoglobin of 11.8 g/dL
- C. Platelet count of 400,000/μL
- D. White blood cell (WBC) count of 2800/μL
Correct Answer: D
Rationale: A low white blood cell (WBC) count in an older patient is concerning as it indicates a potential compromise in the patient's immune function. White blood cells are crucial for fighting infections and a low count could lead to an increased risk of infections. Hematocrit, hemoglobin, and platelet count are important parameters to assess, but a low WBC count takes priority in this case due to its direct impact on immune health.
Which statement by a patient indicates good understanding of the nurse¢â‚¬â„¢s teaching about prevention of sickle cell crisis?
- A. Home oxygen therapy is frequently used to decrease sickling.
- B. There are no effective medications that can help prevent sickling.
- C. Routine continuous dosage narcotics are prescribed to prevent a crisis.
- D. Risk for a crisis is decreased by having an annual influenza vaccination.
Correct Answer: D

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.
The nurse assesses a patient who has numerous petechiae on both arms. Which question should the nurse ask the patient?
- A. Are you taking any oral contraceptives?
- B. Have you been prescribed antiseizure drugs?
- C. Do you take medication containing salicylates?
- D. How long have you been taking antihypertensive drugs?
Correct Answer: C
Rationale: The correct answer is C: 'Do you take medication containing salicylates?' Petechiae are tiny, pinpoint, red or purple spots on the skin due to bleeding under the skin. Salicylates, which are found in medications like aspirin, interfere with platelet function and can lead to petechiae and ecchymoses. Asking about salicylate-containing medications is crucial in this situation. Choices A, B, and D are incorrect because they are not directly related to the development of petechiae.
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.
