A nurse caring for a client who has a peripheral intravenous saline lock understands that its purpose is to:

D. This is the most appropriate technique for evaluating the success of teaching a client a psychomotor skill. A return demonstration involves the client independently performing the skill they have been taught while the nurse observes. This allows the nurse to assess the client's ability to execute the skill correctly, including aspects such as technique, coordination, and safety precautions. Additionally, the nurse can provide immediate feedback and correction if necessary, enhancing the client's learning experience.
A. While answering oral questions can assess the client's understanding of theoretical or conceptual knowledge, it may not effectively evaluate their ability to perform a psychomotor skill. Psychomotor skills involve physical actions and coordination, which cannot be adequately assessed through verbal responses alone.
B. Participating in a discussion group can facilitate sharing of experiences and perspectives among clients, but it may not be the most effective method for evaluating the client's ability to perform a psychomotor skill. Discussion groups are more suitable for exploring attitudes, beliefs, and understanding of concepts rather than assessing physical skills.
C. Written tests typically assess cognitive understanding and retention of information rather than the ability to perform psychomotor skills. While written tests can evaluate knowledge about the steps involved in a skill, they do not directly assess the client's ability to execute the skill itself.

D. Experiencing multiple stressors simultaneously can overwhelm an individual's coping resources and make it more difficult to effectively manage stress. Coping with multiple stressors can lead to feelings of being overwhelmed, heightened anxiety, and decreased ability to cope with each stressor individually.
A. Undergoing a biopsy can be a stressful experience due to uncertainty about the results and fear of the procedure itself. However, the level of difficulty in coping with this stressor can vary among individuals depending on factors such as their coping mechanisms, social support, and previous experiences with medical procedures.
B. Relocating to an assisted-living facility can be a significant life transition, involving changes in living arrangements, loss of independence, and adjustment to a new environment. This stressor can be particularly challenging for individuals who have strong attachments to their current living situation or who are facing health-related issues that necessitate the move.
C. Understanding and researching the stressor can sometimes help individuals cope better by providing knowledge and a sense of control. However, this does not necessarily make coping with the stressor easier, especially if the stressor itself is significant or if the individual lacks adequate support or resources to manage it effectively.
