A nurse in a mental health clinic is assessing a client who has a history of seeking counseling for relationship problems. The client shows the nurse multiple superficial selfinflicted lacerations on their forearms.

The nurse should identify these behaviors as characteristics of which of the following personality disorders?

- A is correct because aPTT (activated partial thromboplastin time) measures the effectiveness of heparin therapy and guides dosage adjustments.

- B is incorrect because PT (prothrombin time) measures the effectiveness of warfarin therapy, not heparin.

- C is incorrect because INR (international normalized ratio) is a standardized version of PT that also monitors warfarin therapy, not heparin.

- D is incorrect because WBC count (white blood cell count) measures the body's immune response and has no relation to heparin therapy.

Choice A rationale:

Storing personal items together on a shelf in the bathroom promotes organization and reduces the risk of tripping or falling over scattered items. Keeping the environment tidy and free of clutter is an essential fall prevention strategy, especially in areas where the client moves frequently.

Choice Brationale:

Wearing a yellow wristband to indicate a fall risk is a common practice in healthcare facilities. However, merely wearing the wristband does not demonstrate a comprehensive understanding of fall prevention strategies. While it is essential for healthcare providers to identify patients at risk of falling, educating the patient about specific strategies to prevent falls is equally important.

Choice C rationale:

Keeping the overhead lights on at all times does not necessarily indicate an understanding of fall prevention strategies. While adequate lighting is important to prevent falls, leaving lights on continuously may not be necessary during daylight hours. It is more effective to ensure there is adequate lighting in commonly used areas and during nighttime hours.

Choice Drationale:

Wearing a restraint around the waist is not a recommended fall prevention strategy. Physical restraints are generally discouraged in healthcare settings due to ethical concerns and the potential to cause harm to the patient. Restraints can lead to complications such as pressure ulcers, loss of muscle strength, and decreased mobility.
