Question 31

Question
About a day and a half after a fraternity-sorority picnic (and for a few days after that), many students experienced gastrointestinal distress (cramps, diarrhea and vomiting), along with fever and nausea.

  • Cholera
  • Salmonella enteritis
  • Stomach Ulcers

Answer
  • True
  • False

Select the ONE statement that is TRUE
Answer
  • Plaque damage to teeth occurs by means of a specific toxin that erodes tooth enamel

Question 36

Question
Select the ONE answer that is TRUE

  • Shigatoxic E.coli (STEC) is uncommon in the US and serious infections are very rare
  • An infected person's feces can contain infectious agents, but their vomitus cannot, due to its highly acidic nature
  • The cysts of both Giardia and Cryptosporidium are readily killed by chlorine, so there is no need to use filtration to purify drinking water

Question 37

Question
Select ALL of the following that are TRUE
Answer
  • Because this opportunistic bacterium is a member of the normal microbiota, use of broad spectrum antibiotic therapy (which kills off most of the other normal microbiota) can lead to Clostridium difficult infections, especially in the elderly
  • Food contaminated with Staphylococcus aureus can only cause illness in people who eat it while the bacteria are still alive
  • The organisms that cause both dental caries and periodontal disease are normal bacterial microbiota that accumulate on teeth as dental plaque, and the caries they cause can be prevented by regular flossing and brushing with fluoride toothpaste plus biannual tooth cleaning by a dental hygienist
  • Polio begins as an intestinal infection that is followed by a production of a neurotoxin that causes damage of motor neurons in the CNS and leads to flaccid paralysis
  • Botulism is transmitted by improperly canned foods containing bacterial spores that germinate to form vegetative bacteria that grow and produce an exotoxin that can lead to cardiac and/or respiratory failure
  • Cholera toxin leads to sever dehydration, but patients can usually be successfully treated by replacing water and salts, either by oral hydration or by IV administration
  • Toxins play a significant role in hepatitis A and botulism, but not in enteritis or oral Candidiasis (thrush)

Answer
  • The signs and symptoms are more apparent in men than in women
  • Signs and symptoms may include painful urination and discharge
  • Pelvic inflammatory disease is not a complication of both of these diseases, just one of them
  • Antibiotic resistance is a significant problem for either of these diseases
  • Due to damage to the fallopian tubes, they may lead to ectopic pregnancy or infertility in women

Question 39

Question

Answer
  • True
  • False

Question 40

Question
Select the ONE statement that is TRUE
Answer
  • Indwelling urethral catheters post little or no risk for nosocomial infections

  • Septicemia, but not septic shock, is associated with loss of blood flow to vital organs
  • In septic shock, the damage is caused by bacteria growing in the lungs and physically clogging them

Question 41

Question
Because prevention of vaginal infections depends on sloughing of glycogen-containing epithelial cells and maintenance of low vaginal pH by normal microbiota, treatment of urinary cystitis with an antibiotic that kills Gram-positive bacteria is highly unlikely vaginal candidiasis in a twenty-something woman

  • False

  • While vaginosis is associated with renal damage, urinary cystitis is not
  • Although condom use will not help prevent vaginosis, personal hygiene can

Question 44

Question
Select the ONE statement that is TRUE
Answer
  • Once an STD is cured, reinfection will not occur, although latent organisms can cause recurrence of some of these diseases
  • With most STDs, when the symptoms go away, one can no longer be considered infectious, so transmission of the disease to a sexual partner is of little concern
  • The latest estimates indicate that 15 million Americans become newly infected with an STD each year, yet these diseases are one of the most under recognized health threats
  • Condoms are not effective in preventing STDs, so vaccination remains the primary means of prevention
  • Women who are promiscuous and practice unprotected sex do not have a higher risk of miscarriage or children with birth defects
