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 who is being discharged after an emergency splenectomy following a motor vehicle crash. Which instructions should the nurse include in the discharge teaching?

• A. Check frequently for swollen lymph nodes.
• B. Watch for excessive bleeding or bruising.
• C. Take iron supplements to prevent anemia.
• D. Wash hands regularly and avoid individuals who are ill.

Correct answer: D

Rationale: The correct answer is D: 'Wash hands regularly and avoid individuals who are ill.' After a splenectomy, the patient is at an increased risk of infection, particularly from gram-positive bacteria. Proper hand hygiene and avoiding contact with sick individuals are crucial to prevent infections. Choices A, B, and C are incorrect because checking for swollen lymph nodes, watching for excessive bleeding or bruising, and taking iron supplements are not specifically related to the increased infection risk post-splenectomy.

3. 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.

4. The nurse is reviewing laboratory results and notes a patient's activated partial thromboplastin time (aPTT) level of 28 seconds. The nurse should notify the health care provider in anticipation of adjusting which medication?

• A. Aspirin
• B. Heparin
• C. Warfarin
• D. Erythropoietin

Correct answer: B

Rationale: The correct answer is B: Heparin. An activated partial thromboplastin time (aPTT) level of 28 seconds indicates a prolonged time, which is associated with heparin administration. Heparin is an anticoagulant medication that affects the intrinsic pathway of the coagulation cascade, leading to an increased aPTT. Aspirin (choice A) affects platelet aggregation and does not directly impact aPTT. Warfarin (choice C) affects the extrinsic pathway of the coagulation cascade and is monitored using the international normalized ratio (INR), not aPTT. Erythropoietin (choice D) is not related to coagulation parameters.

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?

• A. Platelet count
• B. Neutrophil count
• C. Hemoglobin level
• D. White blood cell count

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.
