Deck 1 Flashcards
1
Q
When in doubt about whether to immunize someone,
A
Better to give an extra vaccine dose than to give none. Risk of reaction with re-immunization is minimal.
2
Q
When should you defer an immunization and when should you not defer?
A
Immunization should only be deferred if there’s a moderate to severe illness (with or without fever). For minor illness, you should still immunize.
3
Q
What is the onset and duration of most immunizations (active immunity)
A
Onset is about a month, it lasts for years
4
Q
What is passive immunity and when is it used
A
It’s when you directly give someone antibodies. It’s used post-exposure for certain infections (so the patient has to have a recent risk of exposure)
5
Q
What is the onset and duration of passive immunity
A
Onset is a few hours, usually lasts 6 to 9 months
6
Q
What are some infections we can treat with passive immunity
A
Varicella, Hep A, Hep B, tetanus, rabies
7
Q
Herpes Zoster Vaccine (4 things)
A
Prevents herpes zoster (shingles) in adults aged 50 years and older.
Give 1 dose, then 2 to 6 months later, give another dose.
Can be given to immunosuppressed people.
If they have already received the live zoster vaccine, still give this one.
8
Q
How to calculate packs per day years
A
2 packs per day for 30 years
2 PPD x 30 years = 60 pack year history
9
Q
CAGE for other substances
A
Change the “E” to an “N”
Have you ever needed heroine to feel normal (not be in withdrawal)
10
Q
CAGE scoring
A
2 or more “Yes’ “ means they almost definitely have substance abuse disorder
11
Q
For all ages, what is the leading cause of death, and what is the 10th leading cause

If they don’t have the BRCA 1 and 2, do not screen routinely
14
Q

Consider testing is they are overweight (BMI 25 or greater), and have other risk factors:
Physical inactivity
Family history
Non white
HTN
HDL
CVD
Polycystic ovary syndrome
```
123
DM dx: Plasma glucose
Fasting result is 126 or greater
Random result is 200 or greater with symptoms like polys or unexplained weight loss
(100 to 125 is considered "impaired fasting glucose")
124
DM dx: Oral glucose tolerance test
2 hour plasma glucose is 200 or more after a 75 g glucose load
(140 to 199 is considered "impaired glucose tolerance")
125
DM dx: A1C
6. 5 or greater
| 5. 7 to 6.4 is prediabetic

Reduces hunger
promotes fat loss
Stops or reverses weight gain
132
What should you know about adverse effects of metformin
The main one is GI upset, which can be abated by slow titration
Also B12 loss happens but that's after many years
133

146
Explain treatment for HIV positive people
Antiretroviral therapy.
It's indicated for all adolescents and adults with HIV.
Start as soon as possible

147
Explain pre-exposure prophylaxis for HIV
Begin as soon as possible but after confirming they are HIV negative
148
Explain post exposure prophylaxis for HIV
You give them meds to prevent seroconversion.
It's indicated for someone who isn't HIV positive, but was in a high risk situation in the past 72 hours.
Treatment lasts for 28 days.
149

Other approved tests are combination tests and qualitative HIV-1 RNA
152
Is rapid HIV testing good?
Yes, rapid tests are very accurate. But, if it's positive, you need to confirm with the conventional tests.
