1. A 62-year-old man with chronic anemia is experiencing increased fatigue and occasional palpitations at rest. The nurse would expect the patient's laboratory test findings to include
- A. an RBC count of 4,500,000/μL.
- B. a hematocrit (Hct) value of 38%.
- C. normal red blood cell (RBC) indices.
- D. a hemoglobin (Hgb) of 8.6 g/dL.
Correct answer: B
Rationale: The correct answer is B. In chronic anemia, the hematocrit (Hct) value is a crucial indicator of the proportion of red blood cells in the blood. A hematocrit value of 38% indicates a lower than normal level of red blood cells, which aligns with the patient's symptoms of fatigue and palpitations. Choices A, C, and D are incorrect because a low RBC count, normal RBC indices, and a hemoglobin level of 8.6 g/dL do not specifically address the decreased red blood cell mass associated with chronic anemia.
2. The nurse is planning to administer a transfusion of packed red blood cells (PRBCs) to a patient with blood loss from gastrointestinal hemorrhage. Which action can the nurse delegate to unlicensed assistive personnel (UAP)?
- A. Verify the patient identification (ID) according to hospital policy
- B. Obtain the temperature, blood pressure, and pulse before the transfusion
- C. Double-check the product numbers on the PRBCs with the patient ID band
- D. Monitor the patient for shortness of breath or chest pain during the transfusion
Correct answer: B
Rationale: The correct answer is B. Unlicensed assistive personnel (UAP) can obtain the temperature, blood pressure, and pulse before a transfusion as their education includes measurement of vital signs. UAP would then report the vital signs to the registered nurse (RN). Option A is typically a nursing responsibility to ensure patient safety and avoid errors in patient identification. Option C involves cross-checking important details and ensuring accuracy, which is usually performed by nursing staff to prevent errors. Option D requires monitoring for potential adverse reactions during the transfusion, which is a nursing responsibility due to the need for assessment and intervention in case of complications.
3. Which assessment finding should the nurse caring for a patient with thrombocytopenia communicate immediately to the healthcare provider?
- A. The platelet count is 52,000/µL
- B. The patient is difficult to arouse
- C. There are purpura on the oral mucosa
- D. There are large bruises on the patient's back
Correct answer: B
Rationale: The correct answer is B. Difficulty in arousing the patient may indicate a cerebral hemorrhage, which is life-threatening and requires immediate action. While a low platelet count (choice A) is concerning in thrombocytopenia, it does not require immediate communication unless accompanied by active bleeding or other critical symptoms. Purpura on the oral mucosa (choice C) and large bruises on the patient's back (choice D) are important findings in thrombocytopenia but do not indicate an immediate life-threatening situation like a possible cerebral hemorrhage.
4. 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.
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.
