Self-Evaluation: Self-Enhancement and Self-Verification

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Strategies of Self-Presentation II: Self-Verification

Self-verification is a fundamental psychological drive wherein individuals seek affirmation of their self-concept from others, striving for consistency between their internal self-view and external perceptions. This drive operates even when the self-concept is negative, influencing interpersonal behavior and feedback preferences in complex and often counterintuitive ways. Unlike the self-enhancement motive, which seeks positive evaluations, self-verification prioritizes coherence and...

However, there are many factors that can complicate placement of a peripheral intravenous cannula (PIV), and it is extremely common for PIV attempts to fail. PIV placement may be technically challenging in small...

Source: Rachel Liu, BAO, MBBCh, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA A tension pneumothorax is a life-threatening situation in which excess air is introduced into the pleural space surrounding the lung, either through trauma to the chest cavity or as a spontaneous leak of air from the lung itself. Air trapped within the pleural space causes separation of the lung from the chest wall, disrupting normal breathing mechanisms. Pneumothorax may be small without...
FAQs
Inspection should establish that the needle matches the intended device, its packaging supports that identification, and the needle remains intact and suitable for use. These checks address device-related problems before placement begins. Including them in the clinical workflow helps distinguish an incorrect or compromised needle from a needle that is appropriate for the planned procedure.
Placement verification focuses on whether the needle follows the planned trajectory and whether its tip reaches the intended location. Anatomical landmarks provide one basis for judging position, expected fluid return offers another procedural cue, and ultrasound can show the needle in relation to the target. The appropriate check depends on the procedure and the information it can provide.
Using separate device and placement checks creates a layered safeguard rather than relying on a single observation. A correct needle can still be misplaced, while an accurately directed needle may not be the intended device. Linking both checks therefore supports safer delivery, sampling, injection, or access and makes the verification process more reliable for clinical work, training, and research.
A practical sequence begins by confirming the intended needle and examining its packaging, then checking that the needle is intact and suitable for use. During placement, clinicians assess the planned trajectory and tip position using the approach appropriate to the procedure, such as landmarks, expected fluid return, or ultrasound. This sequence connects device confirmation with location confirmation.
Choice of confirmation method depends on the procedure and on how the planned location can be assessed. Clinicians may use anatomical landmarks, look for expected fluid return, or use ultrasound guidance to evaluate the needle's trajectory and tip position. The selected approach therefore reflects the procedural need for reliable information about where the needle is located.
Consistent verification supports more than immediate placement decisions. By helping prevent wrong-device and misplacement errors, it can improve the reliability of delivery, sampling, injection, or access to a target structure. The same consistency also strengthens patient-safety practices and the quality of clinical training and research, where repeatable checks help make procedural performance easier to assess.
