Correct Answer: D

Rationale: When assessing a venous stasis leg ulcer, the nurse should expect to note a brownish or 'brawny' appearance. This discoloration is often due to hemosiderin deposits. This characteristic finding helps differentiate venous stasis ulcers from other types of ulcers, making it crucial for accurate diagnosis and appropriate treatment.

Correct Answer: A

Rationale: Monitoring weight daily, especially in the morning before breakfast, is crucial in detecting fluid retention early and preventing pulmonary edema. Sudden weight gain can indicate fluid accumulation, prompting timely intervention to prevent complications.

Correct Answer: B

Rationale: For clients with peripheral arterial disease experiencing leg pain while walking, gradually increasing daily walking distance is beneficial. This approach helps improve circulation, build tolerance, and reduce symptoms over time. Compression stockings can also be recommended for some clients to assist with circulation, but the priority teaching point in this scenario is to promote gradual increases in walking distance to enhance vascular health and symptom management.

Correct Answer: A

Rationale: An exercise electrocardiography (ECG) test is used to evaluate the heart's response to physical stress. During the test, the heart's electrical activity is monitored while the client exercises, helping to identify any areas of ischemia or abnormal rhythms. This test helps healthcare providers assess the heart's function and detect any potential issues related to angina or other cardiac conditions.

Correct Answer: A

Rationale: In hyperkalemia, tall, peaked T waves are a distinct ECG finding. These T waves can be seen as a result of increased serum potassium levels, affecting the repolarization phase of the cardiac action potential. It is crucial for healthcare providers to recognize this ECG change promptly as hyperkalemia can lead to serious cardiac arrhythmias and complications.
