Correct Answer is B
Explanation
A. Battery involves physical contact or touching a person without consent. Since no physical action was taken, battery does not apply in this case.
B. Assault is correct. Assault is defined as a threat or attempt to make bodily contact with another person without their consent, causing the person to fear imminent harm. The AP's threat to restrain the client if they don't comply fits this definition.
C. False imprisonment involves unlawfully restricting a person’s freedom of movement, such as restraining them without medical or legal justification. Although the AP threatened restraint, no action was taken yet, so this tort does not apply—yet.
D. Invasion of privacy involves unauthorized access or disclosure of personal information, which is unrelated to this situation.
Correct Answer is C
Explanation
A. Bed sheet is a common item considered a safety risk in real clinical settings, but in this specific safety exercise, it was not the item identified as being on the back of the chair.
B. Patient gown is typically worn by the client and would not usually be placed on the back of a chair as a risk item during a safety evaluation.
C. Beige jacket is correct. In the safety exercise scenario, the beige jacket was on the back of the chair, and it could pose a ligature risk, making it a key item of concern in suicide prevention protocols.
D. Blow dryer may be a potential safety risk in general, but it was not the item noted on the back of the chair in the described scenario.
