Nursing Elites

1. 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.

2. 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.

3. The nurse assesses a patient with pernicious anemia. Which assessment finding would the nurse expect?

• A. Yellow-tinged sclerae
• B. Shiny, smooth tongue
• C. Numbness of the extremities
• D. Gum bleeding and tenderness

Correct answer: C

Rationale: The correct answer is C: Numbness of the extremities. Numbness of the extremities is a common finding in patients with pernicious anemia, which is caused by cobalamin (vitamin B12) deficiency. This deficiency affects the peripheral nervous system, leading to neurological symptoms like numbness and tingling in the extremities. Choices A, B, and D are incorrect: Yellow-tinged sclerae is more indicative of jaundice or liver dysfunction, a shiny smooth tongue is seen in conditions like glossitis, and gum bleeding and tenderness are associated with periodontal disease or vitamin C deficiency, not pernicious anemia.

4. 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.

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?

• A. Have you had any recent weight loss?
• B. Do you have any history of lung disease?
• C. Have you noticed any dark or bloody stools?
• D. What is your dietary intake of meats and proteins?

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.
