1. 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.
2. The health care provider's progress note for a patient states that the complete blood count (CBC) shows a 'shift to the left.' Which assessment finding will the nurse expect?
- A. Cool extremities
- B. Pallor and weakness
- C. Elevated temperature
- D. Low oxygen saturation
Correct answer: C
Rationale: The correct answer is C: Elevated temperature. When a CBC shows a 'shift to the left,' it indicates elevated levels of immature polymorphonuclear neutrophils (bands), which is a sign of infection. In response to the infection, the body increases its temperature as part of the immune response. Choices A, B, and D are incorrect because cool extremities, pallor and weakness, and low oxygen saturation are not typically associated with a 'shift to the left' in a CBC; they are more indicative of other conditions or issues.
3. 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.
4. During a physical assessment, the nurse examines the lymph nodes of a patient. Which assessment finding would be of most concern to the nurse?
- A. A 2-cm nontender supraclavicular node
- B. A 1-cm mobile and nontender axillary node
- C. An inability to palpate any superficial lymph nodes
- D. Firm inguinal nodes in a patient with an infected foot
Correct answer: A
Rationale: The correct answer is A. A 2-cm nontender supraclavicular node is of most concern because enlarged and nontender nodes in this area are highly suggestive of malignancies such as lymphoma. Choice B is less concerning as a 1-cm mobile and nontender axillary node is usually benign. Choice C, an inability to palpate any superficial lymph nodes, could be due to factors like obesity or edema, but it is not necessarily a cause for immediate concern. Choice D, firm inguinal nodes in a patient with an infected foot, may indicate a local reaction to infection rather than a systemic issue related to malignancy.
5. A patient is considering options to manage his/her coronary artery disease. The nurse explains a coronary artery bypass graft procedure will:
- A. Cure the patient's coronary artery disease.
- B. Replace the leaking valve in the heart.
- C. Connect grafts to aorta to improve blood flow.
- D. Place a permanent pacemaker on the heart muscle.
Correct answer: C
Rationale: The correct answer is C. A coronary artery bypass graft procedure involves connecting grafts to the aorta to improve blood flow to the heart muscle by bypassing blocked or narrowed coronary arteries. This procedure does not cure coronary artery disease but helps improve blood supply to the heart. Choices A, B, and D are incorrect because a bypass graft procedure does not cure the underlying disease, replace heart valves, or involve the placement of a pacemaker.
