Question 1 of 5
A patient's complete blood count (CBC) shows a hemoglobin of 19 g/dL and a hematocrit of 54%. Which question should the nurse ask to determine possible causes of this finding?
Correct Answer: B
Rationale: The correct answer is B: "Do you have any history of lung disease?" The elevated hemoglobin and hematocrit levels suggest polycythemia, which can be seen in conditions like chronic obstructive pulmonary disease (COPD). Option A is less relevant as weight loss is not typically associated with these blood count findings. Option C is more indicative of gastrointestinal bleeding rather than a respiratory issue. Option D focuses on dietary factors, which are less likely to cause such significant elevations in hemoglobin and hematocrit levels as seen in this case.
Question 2 of 5
The nurse notes pallor of the skin and nail beds in a newly admitted patient. The nurse should ensure that which laboratory test has been ordered?
Correct Answer: C
Rationale: The correct answer is C, 'Hemoglobin level.' Pallor of the skin and nail beds is a sign of anemia, which is characterized by a low hemoglobin level. Anemia is a condition where there is a decreased number of red blood cells or hemoglobin in the blood, leading to reduced oxygen-carrying capacity. Checking the hemoglobin level would help confirm the presence and severity of anemia, guiding further diagnostic and treatment interventions. Choices A, B, and D are incorrect because platelet count, neutrophil count, and white blood cell count are not typically associated with the pallor of the skin and nail beds, which are more indicative of an underlying anemic condition.
Question 3 of 5
During a physical assessment, the nurse examines the lymph nodes of a patient. Which assessment finding would be of most concern to the nurse?
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.
Question 4 of 5
A patient who had a total hip replacement had an intraoperative hemorrhage 14 hours ago. Which laboratory test result would the nurse expect?
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.
Question 5 of 5
The complete blood count (CBC) indicates that a patient is thrombocytopenic. Which action should the nurse include in the plan of care?
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.
