The labels on the left represent different types of skin infections. Move the labels to the correct part of the concept map or next to the A, B, C descriptions to show your understanding of these infections.
Label the image with the diseases (orange boxes) or causative agents listed for a review of microbial infections of the skin and eyes. A couple of pop-up hints have been provided to help you place the labels correctly.
Label the image to review important structures of the skin.
The ______ forms the integument, and it is the first barrier against microbial invasion.
The outermost portion of the skin is the ___________, whose surface is _____________ and contains antimicrobial ___________ to prohibit microbial penetration.
epidermis; keratinized, peptides
The _____________________ is the uppermost layer of the epidermis, and regularly undergoes ___________________ which removes attached microbes.
stratum corneum; sloughing
Deep to this area of the skin, ___________ glands within the dermis produce a _____ pH secretion called sebum, which exhibits antimicrobial activity.
________ glands, also within the dermal layer, produce secretions containing _________ that degrades peptidoglycan found in many bacterial cells.
In light of all of these natural defense mechanisms, however, the skin still harbors ________________ such as Corynebacterium, Propionibacterium, Candida, Staphylococcus, and Streptococcus species.
Caused by S. pyogenes
pharyngitis that can lead to rheumatic fever if untreated
Caused by S. aureus
scaled skin syndrome
localized skin lesions
caused by S. aureus or S. pyogenes
cellulitis, which can produce lymphangitis
Drag the statements or images to the correct category of diseases to examine the spectrum of skin diseases caused by various microorganisms.
_______ stands for ____________-resistant Staphylococcus aureus, even though these strains are usually resistant to multiple antibiotics.
Because of its resistance, MRSA is classified as a ________threat in the CDC Antibiotic Resistance Report.
S. aureus is a common and hardy contaminant on surfaces, and it can cause bloodstream infections in hospitalized patients, known as __________________ MRSA.
In 2004, MRSA infections began to appear in individuals with no history of hospitalization; these were classified as _______________ MRSA.
CA-MRSA is more common in __________ populations, and its incidence is ________________.
Percentage of salt tolerated by S. aureus in its environment
Percentage of adults thought to be infected with HHV-6 by adulthood
Percentage of adults who are asymptomatic carriers of S. aureus
Percentage of individuals with no recoverable bacteria in their eyes
Based upon all of the information obtained through specimen testing, along with the patient's symptoms, the pathogen is most likely:
B. Bacillus anthracis
Based upon this identification, what was the most likely mode of transmission of this pathogen?
Direct contact with endospores
Based upon this diagnosis, what disease is the patient suffering from?
What was the most likely source of the endospores the patient came in contact with leading to infection?
Animals and animal hides
Which form of treatment should be administered to the patient at this time?
True or False: Vaccination could have prevented the development of this disease in the patient.
Based upon this information, the anthrax cases in 2001 in the United States were transmitted through
the postal service
What laboratory action created a situation in which workers were exposed to Bacillus anthracis in the June 2014 incident?
The chemical treatment used was not sufficient to inactivate the endospores of this organism.
Select all of the statements that illustrate examples of natural defenses present in the skin.
Antimicrobial peptides, which disrupt membranes of bacteria
Lysozyme, which breaks down peptidoglycan
Keratin, which prevents microbe penetration
Sloughing of skin, which removes attached microbes
Select all of the statements that apply to antimicrobial peptides serving as a natural defense present in the skin.
They are found in epithelial cells.
They act by disrupting membranes of bacteria.
They occur in many different types.
Select all of the statements that apply to the pathological aspects of impetigo, a skin disease.
Staphylococcus aureus and Streptococcus pyogenes are the causative organisms.
The most common modes of transmission are direct and indirect contact.
MRSA infections that occur in individuals who have had no recent history in hospitals or clinics are termed community-acquired or CA-MRSA cases.
______________ occurs when the causative virus, which is strongly teratogenic, is transmitted to the fetus in utero; it can subsequently result in miscarriage or multiple permanent defects in the newborn.
the dome shaped central portion of the eye.
the colored part of the eye.
very thin membranelike tissue that covers the eye except the cornea
White fibrous tissue covering all of the eyeball except the cornea
Since the eye's primary function is vision, it is important to have a strong, easily initiated inflammatory response in this region.
Choose the statement that best describes the normal biota of the eye.
The normal biota of the eye is generally sparse
Select all of the statements that apply to bacterial conjunctivitis.
It is caused by more than one type of bacteria.
In children and adults, prevention is through good hygiene.
Select all of the statements that apply to keratitis, a serious eye infection.
Blindness due to herpes is the leading infectious cause of blindness in the United States.
Keratitis can be caused by a eukaryotic organism.
Acanthamoeba infection can cause keratitis, especially in those who wear contact lenses.
Following assessment by the physician, the child is diagnosed with conjunctivitis. Which of the following is the common name for this disease?
The patient's caregiver reports that numerous cases of conjunctivitis have been reported in the child's school. Which of the following is the most common method(s) of transmission of bacterial and viral forms of this disease?
Direct contact and indirect contact
The causative organism (bacterial or viral) of the patient's infection is not confirmed. The RN may anticipate the treatment plan to include which of the following?
Antibiotic eye drops and teaching regarding frequent hand washing
The patient's caregiver asks if the student may return to school that day. Which of the following is the most appropriate response by the RN?
The patient may return to school when symptoms improve and/or the patient may return to school 24 hours after antibiotics are started
The causative organism for measles is a:
Which of the following interactions is most likely to transmit the disease?
Which of the following is the most effective method of measles prevention?
Which of the following would be utilized for treatment for this patient?
all of these
The RN provides education to the students at the college regarding measles symptoms. All of the following presentations, suspicious of measles, are likely contagious, except:
24-year-old male with no fever and resolving generalized rash.
Which of the following actions is most appropriate by the RN?
Call the child's mother for pick up as the child is highly contagious.
Which of the following is the causative organism of impetigo?
Staphylococcus aureus and Streptococcus pyogenes
In addition to impetigo, Staphylococcus aureus may cause all of the following skin infections, except:
All of the following are appropriate descriptors of impetigo lesions, except:
The RN educates the student about the virulence of S. aureus related to lesion formation in impetigo. Which of the following statements by the student demonstrates an understanding of this teaching?
The bacteria make a toxin that makes it so my skin cells do not bind well.
