A nursing student wants to know the differences between hospital-associated methicillin-resistant Staphylococcus aureus (HA-MRSA) and community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA).
 
  Which statements about CA-MRSA are true? (Select all that apply.)
  a. Twenty percent to 30 of the general population are colonized with CA-MRSA.
  b. Boils caused by CA-MRSA can be treated without antibiotics.
  c. CA-MRSA is less dangerous than HA-MRSA.
  d. CA-MRSA does not cause necrotizing fasciitis.
  e. CA-MRSA is transmitted by airborne droplets.

Question 2

A patient is about to receive penicillin G for an infection that is highly sensitive to this drug.
 
  While obtaining the patient's medication history, the nurse learns that the patient experienced a rash when given amoxicillin (Amoxil) as a child 20 years earlier. What will the nurse do?
  a. Ask the provider to order a cephalosporin.
  b. Reassure the patient that allergic responses diminish over time.
  c. Request an order for a skin test to assess the current risk.
  d. Suggest using a desensitization schedule to administer the drug.

Answer to Question 1

ANS: A, B, C
CA-MRSA is thought to be present in 20 to 30 of the population, and many of these individuals are asymptomatic carriers. Boils caused by CA-MRSA can often be treated by surgical drainage alone. CA-MRSA is less dangerous than HA-MRSA but more dangerous than methicillin-sensitive Staphylococcus aureus (MSSA). CA-MRSA generally causes mild skin infections but can cause more serious infections, such as necrotizing fasciitis. CA-MRSA is transmitted by skin-to-skin contact and by contact with contaminated objects.

Answer to Question 2

ANS: C
Allergy to penicillin can decrease over time; therefore, in patients with a previous allergic reaction who need to take penicillin, skin tests can be performed to assess the current risk. Until this risk is known, changing to a cephalosporin is not necessary. Reassuring the patient that allergic responses will diminish is not correct, because this is not always the case; the occurrence of a reaction must be confirmed with skin tests. Desensitizing schedules are used when patients are known to be allergic and the drug is required anyway.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
