Nursing Elites

1. 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.

2. The nurse is caring for a patient post-coronary artery bypass graft procedure who is on a nitroglycerin intravenous drip. The nurse understands the importance of nitroglycerin with this procedure as:

• A. Decreasing myocardial oxygen supply.
• B. Increasing preload.
• C. Decreasing cardiac output.
• D. Decreasing afterload.

Correct answer: D

Rationale: Nitroglycerin is a vasodilator that works by decreasing afterload, which is the pressure the heart must work against to eject blood during systole. By reducing afterload, nitroglycerin helps the heart pump more effectively and decreases the workload on the heart. This results in improved cardiac output and decreased myocardial oxygen demand. Choices A, B, and C are incorrect because nitroglycerin does not decrease myocardial oxygen supply, increase preload, or decrease cardiac output.

3. After a patient with pancytopenia undergoes a bone marrow aspiration from the left posterior iliac crest, which action would be important for the nurse to take?

• A. Elevate the head of the bed to 45 degrees.
• B. Have the patient lie on the left side for 1 hour.
• C. Apply a sterile 2-inch gauze dressing to the site.
• D. Use a half-inch sterile gauze to pack the wound.

Correct answer: B

Rationale: After a bone marrow aspiration, it is important to have the patient lie on the left side for 30 to 60 minutes to decrease the risk of bleeding. Elevating the head of the bed to 45 degrees does not directly address the risk of bleeding. Applying a sterile 2-inch gauze dressing to the site is important for wound care but does not specifically address post-procedural positioning. Using a half-inch sterile gauze to pack the wound is not necessary after a bone marrow aspiration.

4. 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.

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.
