NR565 Final - Week 8 questions and answers with accurate solutions 2026(PASSED)

Tdap Vaccine

given to adolescents > 10 years old and adults

Tdap contraindications

if a prior vaccination with DTap produced an immediate anaphylactic reaction or encephalopathy within 7 days of vaccination.

Varicella contraindications

for pregnant patients, individuals with certain cancers (leukemia, lymphomas), and individuals with hypersensitivity to neomycin or gelatin, both of which are in the vaccine. The vaccine should be avoided by immunocompromised individuals including HIV infection or congenital immunodeficiency, and those taking immunosuppressants.

Hepatitis B vaccine Contraindication

prior anaphylactic reaction to Hep B or baker's yeast

Live Vaccine reminder

should not be given to those who are immunocompromised because they are unable to create an effective immune response and are a high risk for developing the infection. Additionally, pregnant woman should not receive live vaccines due to the risk of passing the infection to the baby

Live virus

MMR, MMRV, Varicella, Rotavirus, Influenza

Toxoid

DTAP - diphtheria and tetanus and acellular pertussis adsorbed, hepatitis B (recombinant), and inactivated poliovirus vaccine.

Inactive Viral Antigen

Hep A, Hep B, Influenza (inactivated), Poliovirus.

Herd Immunity

The resistance to an infectious organism because a large group of people is immune to the infectious organism through immunization/vaccine. Herd or Community immunity is contingent on the likelihood individuals are prone to the infection will encounter the infected person. For example, most the people in the community are immune to an infectious disease, which means everyone does not need immunity to prevent the spread of the infection.

Active Immunity

When the immune system produce antibodies in response to an antigen by the vaccine, or by the infection itself. For example, if a person who has never had hepatitis B contracts Hep B and recovers from it, that person becomes immune to Hep B because of the immune system's antibody response to the hepatitis B virus.

Passive Immunity

occurs naturally. This type of immunity is passed on when an antibody is produced in another host. For example, immunity is passed on from a mother to her infant or by artificial administration of antibody-containing formulations.

Definition of vaccine

a preparation containing whole or fractionated microorganisms

post exposure prophylaxis for suspected rabies bite

post exposure prophylaxis (PEP) consists of a dose of human rabies immune globulin (HRIG) and rabies vaccine given on the day of the rabies exposure, and then a dose of the vaccine given again on days 3, 7 and 14. For people who have never been vaccinated against rabies previously, PEP should always include administration of both HRIG and rabies vaccine. The combination of HRIG and the vaccine is recommended for both bite and non-bite exposures, regardless of the interval between exposure and initiation of treatment.

post vaccine side effects

many children experience local reactions (discomfort, swelling, and erythema) at injection sites. Fever can also be common. Very rare but severe effects include anaphylaxis; acute encephalopathy, and vaccine-associated paralytic poliomyelitis.

MMR:

local reactions, rash, fever, swollen glads in cheeks, neck & under the jaw; pain, stiffness and swelling in joints (mild)

Anaphylaxis and thrombocytopenia (severe)

DTAP

local reactions, fever, fretfulness, drowsiness, anorexia, persistent crying (mild)

acute encephalopathy, convulsions, shock-like state (severe)

Varicella

local reactions, fever, mild varicella like rash (local or generalized)

Hep A

local soreness, headaches anorexia, fatigue (mild)

anaphylaxis (severe)

Hep B

local discomfort, fever (mild)

anaphylaxis (severe)

influenza (inactivated)

local reactions, fever

influenza (live attenuated)

runny nose, headache, cough, fever

Pheunmococcal:

local reactions, fever, irrability

Meningococcal

local reactions, headache, fatigue

Rotavirus

diarrhea, vomiting, ear infection, runny nose, sore throat (milk)

intussusception (rare)

HPV

local reactions and fainting

who can receive attenuated influenza vaccine (FluMist)

approved after age 2
