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.)

Correct Answer is B
Explanation
A. Wheezing in all lung fields may indicate respiratory issues but does not directly support the diagnosis of Excess Fluid Volume.
B. Pitting edema in bilateral lower extremities is a classic sign of fluid overload, which directly supports the diagnosis of Excess Fluid Volume.
C. An oral fluid intake of 2000 mL in 24 hours is within normal limits for an adult and does not necessarily indicate Excess Fluid Volume without other symptoms.
D. Significant fatigue for more than one month could be related to a variety of conditions and is too nonspecific to support the diagnosis of Excess Fluid Volume without additional assessment data.
Correct Answer is A
Explanation
A. Poorly coordinated care and nosocomial infections are examples of errors: Poorly coordinated care, such as miscommunication between healthcare providers or lack of continuity in care, and nosocomial infections (infections acquired in the healthcare setting) are examples of errors that can compromise patient safety and contribute to adverse events.
B. Handoff errors are not causes of adverse events: Handoff errors, including miscommunication during transitions of care, are significant contributors to adverse events in healthcare settings. Improper handoffs can lead to misunderstandings, delays in treatment, and errors in medication administration.
C. Medication errors are intentional: Medication errors are unintended and can occur due to various factors, including human error, system failures, and communication breakdowns. They are not intentional acts.
D. As many as 10% of medication errors are preventable: Medication errors are often preventable with the implementation of safety measures such as barcode scanning, medication reconciliation, and standardized protocols. The percentage of preventable medication errors may vary depending on the healthcare setting and the effectiveness of safety initiatives.
