A nurse is caring for a client who has an elevated potassium level and is on a cardiac monitor.
The nurse is aware that hyperkalemia may be associated with changes to the T-wave. On the graphic, point and click on the area of the electrocardiogram (ECG) that represents the T-wave. (Selectable areas, or "Hot Spots," can be found by moving your cursor over the artwork until the cursor changes appearance, usually into a hand. Click only on the Hot Spot that corresponds to your answer.)
The Correct Answer is "{\"xRanges\":[104.2578125,134.2578125],\"yRanges\":[114.30078125,144.30078125]}"

Correct Answer is C
Explanation
A. The client has circumoral cyanosis: Circumoral cyanosis, or bluish discoloration around the mouth, is a sign of hypoxia but may not be present in all cases of hypoxemia. Pulse oximetry provides a more objective measurement.
B. The client's heart rate is 86 bpm: Heart rate may be within normal limits even in the presence of hypoxemia, as compensatory mechanisms may not be fully activated.
C. The client has a pulse ox of 90% on room air: A pulse oximetry reading of 90% indicates hypoxemia (oxygen saturation below normal levels), which is a significant finding, especially in a client with COPD who may already have compromised respiratory function.
D. The client is lethargic: Lethargy may occur with severe hypoxemia, but it is a late sign and may not always be present. Monitoring oxygen saturation is more reliable for early detection of hypoxemia.
Correct Answer is C
Explanation
A. Incompetence: Incompetence refers to a lack of skill or ability to perform a task effectively. It is not a desirable quality in a leader and would hinder rather than facilitate the implementation of new processes.
B. Integrity: Integrity is essential for a leader but is not specifically related to implementing new suggestions or initiatives. Integrity involves honesty, ethics, and adherence to moral principles.
C. Initiative: Initiative refers to the ability to take action and drive forward new ideas or projects. A leader with initiative is proactive and encourages innovation and improvement within the organization. Implementing suggestions for streamlining processes requires initiative to initiate change and drive improvement.
D. Fear: Fear is not a desirable quality in a leader when it comes to implementing changes or new initiatives. Leaders need to be confident, decisive, and willing to take calculated risks to drive positive change and improvement. Fear can inhibit innovation and progress.
