Complete Chapter Questions With Answers
Sample Questions Are Posted Below
| 1. | Which of the following clients is most susceptible to experiencing the effects of inadequate erythropoiesis? A client: | |
| A) | Who has developed renal failure as a result of long-standing hypertension | |
| B) | Who recently experienced an ischemic stroke and who remains bedridden | |
| C) | Whose heavy alcohol use has culminated in a diagnosis of pancreatitis | |
| D) | Whose estimated blood loss during recent surgery was 700 mL | |
| Ans: | A | |
| Feedback: | ||
| Kidney failure causes an absence of erythropoietin production. As a result, hypoxia does not result in erythropoiesis. Stroke, pancreatitis, and recent blood loss do not directly impair the body’s ability to create new red blood cells. | ||
| 2. | Sue is fatigued, and some blood tests are done. Her results include Hct 40%; Hgb 8g/dL; WBC 8000; and platelets 175,000. The nurse should interpret Sue’s blood work as indicative of: | |
| A) | High platelets/thrombocytosis | |
| B) | Low WBC count/granulocytopenia | |
| C) | Low hemoglobin/anemia | |
| D) | High hematocrit/polycythemia | |
| Ans: | C | |
| Feedback: | ||
| All of the laboratory values are within normal range except for the hemoglobin, which is low. Low hemoglobin is associated with iron deficiency anemia. | ||
| 3. | The client is an average-sized adult and has abnormal microcytic hypochromic red blood cells due to a long-term, chronic disease. Which of the following complete blood count (CBC) results is characteristic of her type of anemia? | |
| A) | Hematocrit 44% | |
| B) | Reticulocytes 1.5% | |
| C) | Band cells 3000/mL | |
| D) | Hemoglobin 8 g/dL | |
| Ans: | D | |
| Feedback: | ||
| Anemia of chronic disease is characterized by a low hemoglobin level, low hematocrit, and low reticulocyte count. The quantity of band cells, immature neutrophils released from the marrow, is unrelated to the anemia. | ||
| 4. | A client presents to the emergency department with severe menstrual bleeding where she is soaking three to 4 pads/hour. Following assessment, which of the following findings indicates that her body is trying to increase its cardiac output? Select all that apply. | |
| A) | Heart rate 120 beats/minute | |
| B) | Deep respirations with expiratory wheezes | |
| C) | Light pink mucous membranes | |
| D) | Complaints of chest “palpitations” | |
| E) | Pale bluish nail beds | |
| Ans: | A, D | |
| Feedback: | ||
| Anemia is frequently the result of tissue oxygen deficit, which is secondary to decreased circulating red blood cells (RBCs) or hemoglobin for oxygen delivery. The redistribution of the blood from cutaneous tissues or the lack of hemoglobin causes pallor of the skin, mucous membranes, conjunctivae, and nail beds. Tachycardia and palpitations may occur as the body tries to compensate with an increase in cardiac output. | ||
