1. Which statement by a patient indicates good understanding of the nurse’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
Rationale: Because infection is the most common cause of a sickle cell crisis, influenza, Haemophilus influenzae, pneumococcal pneumonia, and hepatitis immunizations should be administered.
2. A patient who had a total hip replacement had an intraoperative hemorrhage 14 hours ago. Which laboratory test result would the nurse expect?
- A. Hematocrit of 46%
- B. Hemoglobin of 13.8 g/dL
- C. Elevated reticulocyte count
- D. Decreased white blood cell (WBC) count
Correct answer: C
Rationale: The correct answer is C: Elevated reticulocyte count. Hemorrhage leads to the release of reticulocytes (immature red blood cells) from the bone marrow into circulation as a compensatory mechanism to replenish lost red blood cells. This response helps in restoring the oxygen-carrying capacity of the blood. Choices A and B, hematocrit of 46% and hemoglobin of 13.8 g/dL, may not reflect the immediate response to hemorrhage within 14 hours. Choice D, decreased white blood cell (WBC) count, is not directly related to the body's response to hemorrhage.
3. When providing care for a patient with sickle cell crisis, what is important for the nurse to do?
- A. Monitor the patient's intake of oral and IV fluids
- B. Evaluate the effectiveness of opioid analgesics
- C. Encourage the patient to ambulate as much as tolerated
- D. Educate the patient about high-protein, high-calorie foods
Correct answer: B
Rationale: The correct answer is to evaluate the effectiveness of opioid analgesics. In sickle cell crisis, pain is the most common symptom and is usually managed with large doses of continuous opioids. Monitoring fluid intake (Choice A) is important, but limiting fluids may not be necessary. Encouraging ambulation (Choice C) is generally good but may not be the priority during a sickle cell crisis. Educating the patient about nutrition (Choice D) is important for overall health but may not be the immediate focus during a crisis.
4. A patient in the emergency department complains of back pain and difficulty breathing 15 minutes after a transfusion of packed red blood cells is started. The nurse's first action should be to
- A. administer oxygen therapy at a high flow rate
- B. obtain a urine specimen to send to the laboratory
- C. notify the healthcare provider about the symptoms
- D. disconnect the transfusion and infuse normal saline
Correct answer: D
Rationale: The patient's symptoms, back pain, and difficulty breathing after the transfusion indicate a possible acute hemolytic reaction, a severe transfusion reaction. The priority action in this situation is to discontinue the transfusion immediately to prevent further complications. Infusing normal saline helps maintain the patient's intravascular volume and prevent renal damage. Administering oxygen or obtaining a urine specimen is not the most urgent action and could delay essential treatment. Notifying the healthcare provider is important but should come after ensuring the patient's safety by stopping the blood transfusion.
5. A patient who has immune thrombocytopenic purpura (ITP) has an order for a platelet transfusion. Which information indicates that the nurse should consult with the healthcare provider before obtaining and administering platelets?
- A. Platelet count is 42,000/µL
- B. Petechiae are present on the chest
- C. Blood pressure (BP) is 94/56 mm Hg
- D. Blood is oozing from the venipuncture site
Correct answer: A
Rationale: The correct answer is A. Platelet transfusions are not usually indicated until the platelet count is below 10,000 to 20,000/µL unless the patient is actively bleeding. In this scenario, the platelet count of 42,000/µL is not significantly low to warrant a platelet transfusion without active bleeding. Consulting with the healthcare provider is essential before giving the transfusion to ensure the appropriateness of the treatment. Choices B, C, and D are not directly related to the need for consulting before a platelet transfusion. Petechiae, low blood pressure, and oozing from the venipuncture site are common findings in patients with ITP and may not necessarily contraindicate a platelet transfusion at this platelet count.
