Self-Presentation: Self-Monitoring and Self-Handicapping02:05

Self-Presentation: Self-Monitoring and Self-Handicapping

44.8K
People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Self-Presentation

323
Self-presentation is a fundamental aspect of social interaction, shaping both how others perceive individuals and how they view themselves. This dynamic process influences behaviors in various social settings, often leading people to adjust their appearance, speech, and demeanor to align with their desired identity. While self-presentation can be deliberate or unconscious, it plays a critical role in interpersonal relationships and self-perception.Forms of Self-PresentationSelf-presentation can...

Acute Pyelonephritis II: Diagnostic Studies and Management

419
Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...

Acute Pancreatitis II: Clinical Manifestations and Management

873
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

Nursing Assessment:Nursing management of acute coronary syndrome (ACS) involves taking the patient's history, focusing on primary complaints such as chest pain, dyspnea, and excessive sweating (diaphoresis), as well as other symptoms like back or jaw pain, nausea, vomiting, palpitations, dizziness, and fatigue. The nurse also reviews the patient's history of cardiac events, risk factors such as hypertension, diabetes, smoking, family history, and current medications.In the objective assessment,...

Acute Kidney Injury (AKI) results in an inability to maintain fluid, electrolyte, and acid-base balance. Effective nursing management is critical in improving patient outcomes and includes comprehensive patient assessment and targeted interventions.Comprehensive Patient AssessmentA detailed history collection is essential, focusing on any recent infections, nephrotoxic medication use, or chronic conditions such as hypertension and diabetes that may contribute to AKI. During the physical...

Area of Science:

  • Neurology
  • Neuroscience

Background:

  • Functional neurological disorders (FND) are prevalent, causing significant morbidity and healthcare expenses.
  • Patients frequently present with acute symptoms like dissociative seizures or stroke-like weakness.

Purpose of the Study:

  • To highlight the diagnostic criteria for FND based on clinical presentation.
  • To emphasize the importance of physical examination in diagnosing FND.
  • To outline the benefits of early diagnosis and patient education.

Main Methods:

  • Review of clinical presentations of FND.
  • Analysis of diagnostic features distinguishing FND from organic neurological disorders.
  • Evaluation of the impact of diagnosis and management on patient outcomes.

Main Results:

  • Diagnostic clues for dissociative seizures include specific movement characteristics and high frequency in well individuals.
  • Positive physical signs like Hoover's sign and distractibility indicate functional weakness.
  • Normal investigations are common in FND, underscoring the role of clinical assessment.

Conclusions:

  • Accurate diagnosis of FND relies on detailed history and careful clinical examination.
  • A clear, non-judgmental explanation of FND, supported by reliable information, is crucial.
  • Prompt referral to neurology and effective management strategies improve patient distress and outcomes.
