Nursing Elites

1. A healthcare provider reviews the laboratory data for an older patient. The healthcare provider would be most concerned about which finding?

• A. Hematocrit of 35%
• B. Hemoglobin of 11.8 g/dL
• C. Platelet count of 400,000/μL
• D. White blood cell (WBC) count of 2800/μL

Correct answer: D

Rationale: A low white blood cell (WBC) count in an older patient is concerning as it indicates a potential compromise in the patient's immune function. White blood cells are crucial for fighting infections and a low count could lead to an increased risk of infections. Hematocrit, hemoglobin, and platelet count are important parameters to assess, but a low WBC count takes priority in this case due to its direct impact on immune health.

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. 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.

4. Which patient statement to the nurse indicates a need for additional instruction about taking oral ferrous sulfate?

• A. I will call my health care provider if my stools turn black.
• B. I will take a stool softener if I feel constipated occasionally.
• C. I should take the iron with orange juice about an hour before eating.
• D. I should increase my fluid and fiber intake while I am taking iron tablets.

Correct answer: A

Rationale: It is normal for the stools to appear black when a patient is taking iron, and the patient should not call the health care provider about this.

5. A patient who is receiving methotrexate for severe rheumatoid arthritis develops a megaloblastic anemia. The nurse will anticipate teaching the patient about increasing oral intake of

• A. iron.
• B. folic acid.
• C. cobalamin (vitamin B12).
• D. ascorbic acid (vitamin C).

Correct answer: C

Rationale: The correct answer is C: cobalamin (vitamin B12). Methotrexate can lead to a deficiency in cobalamin, resulting in megaloblastic anemia. Therefore, increasing the oral intake of cobalamin is essential to address this deficiency. Choice A, iron, is incorrect because megaloblastic anemia caused by methotrexate is not typically due to iron deficiency. Choice B, folic acid, is also incorrect as methotrexate does not directly cause folic acid deficiency. Choice D, ascorbic acid (vitamin C), is incorrect as it is not directly related to megaloblastic anemia caused by methotrexate; instead, cobalamin is the key vitamin that needs attention.
