Elevated ST segment
Wide QRS
Inverted P wave
Abnormally prominent U wave
The Correct Answer is D
A. Elevated ST segment is typically seen with conditions like pericarditis or acute myocardial injury, not hypokalemia.
B. Wide QRS could be related to various conditions, including bundle branch block or electrolyte disturbances, but it is not specifically indicative of hypokalemia.
C. Inverted P wave could be due to atrial arrhythmias but is not a hallmark of hypokalemia.
D. Abnormally prominent U wave is a classic sign of hypokalemia and is often seen following the T wave on an EKG.

Correct Answer is D
Explanation
A. Documenting the patient's need for restraints is important but does not address the issue of restraining a competent patient against their will. This is an issue of patient rights and autonomy.
B. Not informing the patient is inappropriate, but the key issue is the lack of consent to be restrained, not just the failure to inform.
C. While failing to get a physician's order is critical for legal and safety reasons, the core issue here is the violation of the patient's autonomy and rights.
D. Restraining a competent patient against their will without consent is considered an intentional tort because it involves touching the patient in an unauthorized manner, which is a direct violation of their rights. This can result in legal action for assault or battery.
Correct Answer is B
Explanation
A. Autonomy refers to respecting the patient’s right to make their own decisions. While important, it is not the ethical principle that guides the nurse's decision to report the situation to Adult Protective Services.
B. Nonmaleficence refers to the duty to do no harm. Reporting the neglect of the client to Adult Protective Services is consistent with preventing further harm and ensuring the client’s safety.
C. Justice refers to fairness and equal treatment. While the nurse is working to protect the client, the situation involves more than just fairness, making nonmaleficence the more applicable principle.
D. Fidelity refers to loyalty and keeping promises, but it does not specifically guide the nurse’s action in this situation.
