Respiratory System Abnormal Finding II: Palpation and Auscultation01:31

Respiratory System Abnormal Finding II: Palpation and Auscultation

2.1K
In assessing respiratory abnormalities, palpation and auscultation are critical tools for detecting and interpreting various pathophysiological changes. These techniques provide insight into underlying disorders by evaluating tactile sensations and sounds produced by the respiratory system.
Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:

Pharynx01:20

Pharynx

9.7K
The pharynx, a tubular structure framed by skeletal muscle and lined with mucous membrane, extends continuously from the nasal cavities. It is segmented into three major areas: the nasopharynx, oropharynx, and laryngopharynx.
Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...

Epistaxis01:30

Epistaxis

857
Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

Suctioning the Oropharyngeal Airway01:25

Suctioning the Oropharyngeal Airway

1.7K
In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Larynx01:21

Larynx

6.4K
The human larynx, often referred to as the voice box, is an intricate organ located in the neck. It serves as a pathway for air to enter the lungs during respiration and is an essential component of voice production.
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids,...

Principal Stresses: Problem Solving01:15

Principal Stresses: Problem Solving

715
When analyzing two planes intersecting at right angles under the influence of shearing, tensile, and compressive stresses, it is essential to identify principal planes, maximum shearing stress, and principal stresses. To find the principal planes, apply a formula that equates them to twice the shearing stress divided by the difference between tensile and compressive stresses.

Area of Science:

  • Child language acquisition
  • Phonological development
  • Speech sound disorders

Background:

  • Early sound systems in children often exhibit predictable error patterns.
  • Coronal fricatives (e.g., /s/, /z/, /θ/, /ð/) are common targets for phonological processes.
  • Understanding these errors is crucial for diagnosing and treating speech sound disorders.

Purpose of the Study:

  • To investigate predicted versus attested error patterns of coronal fricatives in monolingual English-acquiring children.
  • To identify and analyze instances of a "developmental conspiracy" in phonological acquisition.
  • To examine the life-cycle of phonological conspiracies using cross-sectional and longitudinal data.

Main Methods:

  • Cross-sectional study of 234 children (ages 3;0 to 7;9) with phonological delays.
  • Analysis of error patterns involving coronal fricatives as targets and repairs.
  • Supplemental longitudinal data collection to replicate cross-sectional findings.
  • Theoretical modeling using a modified Optimality Theory with Candidate Chains.

Main Results:

  • Identified specific instantiations of a "developmental conspiracy" in children's phonological systems.
  • Observed typological anomalies in fricative error patterns.
  • Cross-sectional and longitudinal data confirmed the existence and replication of these conspiracies.
  • Demonstrated that certain anomalies align with theoretical predictions.

Conclusions:

  • The study provides evidence for a "developmental conspiracy" influencing phonological error patterns in English-acquiring children.
  • Findings offer insights into the systematic nature of speech sound acquisition and delay.
  • A modified Optimality Theory with Candidate Chains effectively accounts for observed phonological anomalies.
