Q: The DTP series of injections is intended for administration to

(a) :  infants
(b) :  children
(c) :  children 6 years and older
(d) :  children and adults
(e) :  only after puberty
Answer:  infants
Explanation:   Diphtheria & Tetanus Toxoid and Pertussis Vaccine (DTP) is administered as a series of four injections starting when the baby is 6 weeks to 2 months of age. Two additional in-jections are given at 6-week intervals, with a final dose given 1 year later. If needed, a booster injection can be given when the child is 4 to 6 years old. DTP must never be iven to children older than 6 years because of serious reactions that may occur.

Q: Units for expressing radioisotope decay include the I. rad II. curie III. Becquerel

(a) :  I only
(b) :  III only
(c) :  I and II only
(d) :  I and III only
(e) :  I, II, and III
Answer:  I and III only
Explanation:  For many years, the curie (Ci) has been the basic unit for expressing radioisotope decay. Now the becquerel is recognized as the "official" unit. One becquerel equals one de- cay per second (dps). 1 curie =3.7 x 1010 bq (dps) The rad is a quantitative measure of radioactivity.

Q: Which of the following preparations will induce passive rather than active immunity?

(a) :  tetanus toxoid
(b) :  botulism antitoxin
(c) :  typhoid vaccine
(d) :  mumps virus vaccine, attenuated
(e) :  cholera vaccine
Answer:  botulism antitoxin
Explanation:  Passive immunizations are usually accomplished by the administration of purified and concentrated antibody solutions (antitoxins) derived from humans or animals that have been actively immunized against a live antigen. Active immunizations are usually accomplished by the administration of one of the following: (1) toxoids, (2) inactivated (killed) vaccines, (3) live attenuated vaccines.

Q: Monitoring of INR is essential in monitoring patients using

(a) :  heparin
(b) :  lamotrigine
(c) :  warfarin
(d) :  glimepiride
(e) :  acarbose
Answer:  warfarin
