A patient has a Pseudomonas aeruginosa infection that is sensitive to aminoglycosides, and the prescriber orders gentamicin.
 
  The patient tells the nurse that a friend received amikacin Amikin for a similar infection and wonders why amikacin was not ordered. What will the nurse tell the patient? a. Amikacin is given when infectious agents are resistant to other aminoglycosides.
  b. Amikacin is more vulnerable to inactiva-tion by bacterial enzymes.
  c. Amikacin is a narrow-spectrum drug and will probably not work for this infection.
  d. Gentamicin is less toxic to the ears and the kidneys.

Question 2

A nurse is teaching a course in bioterrorism to a group of military nurses. Which statement by a military nurse indicates understanding of the teaching?
 
  a. Although smallpox has been eradicated, it remains a threat.
  b. Anthrax is spread rapidly from person to person.
  c. Pneumonic plague is not transmitted from person to person.
  d. Terrorists spreading tularemia would most likely put it in the water supply.

Answer to Question 1

A
Resistance to amikacin is uncommon at this point; to minimize the emergence of amika-cin-resistant bacteria, this drug is reserved for infections in which resistance to other aminogly-cosides has developed. Amikacin is the least susceptible to inactivation by bacterial enzymes. Amikacin is a broad-spectrum antibiotic. All aminoglycosides are ototoxic and nephrotoxic.

Answer to Question 2

A
Smallpox has been eradicated as an endemic disease but it remains a threat because so many people are un-immunized. The virus is still available in laboratories throughout the world. Anth-rax is not spread from person to person. Pneumonic plague is spread from person to person. Tu-laremia would be spread by terrorists as an aerosol.
