Assessing Body Temperature - Tympanic membrane01:14

Assessing Body Temperature - Tympanic membrane

569
Assessing tympanic membrane temperature involves using a tympanic membrane thermometer (TMT). Here is a step-by-step guide:
Step 1: Begin by practicing good hand hygiene to prevent the transmission of microorganisms.
Step 2: Turn on the thermometer and wait until the ready sign appears on the screen to ensure accurate measurement.
Step 3: Slide the probe cover in place to prevent cross-contamination.
Step 4: Instruct the patient to tilt their head to the side for comfort and check for cerumen...

Anatomy of the Ear01:16

Anatomy of the Ear

7.3K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

Hand hygiene01:23

Hand hygiene

3.1K
Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

443
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Suctioning the Oropharyngeal Airway01:25

Suctioning the Oropharyngeal Airway

185
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...

Area of Science:

  • Otolaryngology
  • Primary Care Medicine

Background:

  • Otitis externa, or swimmer's ear, is a common condition involving inflammation of the external auditory canal.
  • It is often linked to moisture exposure and minor trauma to the ear canal.

Purpose of the Study:

  • To present a practical, evidence-based management strategy for otitis externa tailored for family physicians.
  • To guide clinicians in differentiating and treating various forms of the condition.

Main Methods:

  • Literature review of MEDLINE and PubMed databases.
  • Analysis of studies published between 1993 and 2023.

Main Results:

  • Management principles include infection elimination, pain control, patient education, and recurrence prevention.
  • Topical therapies are the mainstay for uncomplicated otitis externa.
  • Complicated cases may necessitate systemic treatments.

Conclusions:

  • Clinical assessment, including history and physical examination, is crucial for diagnosing acute, chronic, or necrotizing otitis externa.
  • Immunosuppressed individuals are at higher risk for necrotizing otitis externa and require vigilant monitoring.
