Some questions for folks....

1. Which DEA# is a Valid DEA# for a Dr. M Rubin?

a. AR 2174828

b. AR 4695283

c. AB 1723647

d. AM 4695282

A valid DEA number consists of

* 2 letters and 7 digits

* the first letter is either an " A " or a " B "

* the second letter is the initial of the registrant's last name

* the seventh digit is a " checksum " that is calculated as:

o add together the first, third and fifth digits

o add together the second, fourth and sixth digits and multiply the sum by 2

o add the above 2 numbers

o the last digit (the one's value) of this last sum is used as the

seventh digit in the DEA number

Options c & d don't match the first letter of the last name ®.

Option A doesn't pass the check-sum:

2 + 7 + 8 = 17

1 + 4 + 2 = 7

7 * 2 = 14

14 + 17 = 31

So 1 would be the checksum digit.

Option B does pass the check-sum:

4 + 9 + 2 = 15

6 + 5 + 8 = 19

19 * 2 = 38

38 + 15 = 53

So 3 would be the checksum digit.

So the answer is B

2. In an order reading " Flagyl 500 mg q6h x 7 days, " the most

important missing piece of information is the:

a. generic drug name.

b. route of administration.

c. frequency.

d. duration.

You don't have to have a generic drug name on a prescription. You DO

need to know if it's going to be given orally, via injection,

rectally, etc. They have frequency in the sig (q6h)

They have duration (x 7 days), which also gives you quantity to

dispense. So B is the answer, because the SIG doesn't give you route

of administration

3. If a pharmaceutical is to be stored in a " cold place, " the

appropriate temperature range for storage is:

a. refrigerator, at 2 degrees C to 8 degrees C (36 degrees F to 46 degrees F).

b. cool, at 8 degrees C to 15 degrees C (46 degrees F to 59 degrees F).

c. room temperature, at 15 degrees C to 30 degrees C (59 degrees Fto

86 degrees F).

d. warm, at 30 degrees C to 40 degrees C (86 degrees F to 104 degrees F).

I found this chart somewhere earlier today, which means that A

(refrigerator) is the correct answer.

* Freezer—A place in which the temperature is maintained

thermostatically between -20° C and -10° C (-4° F and 14° F).

* Cold—Any temperature not exceeding 8° C (46° F). A refrigerator is a

cold place in which the temperature is maintained thermostatically

between 2° C and 8° C (36°- 46° F).

* Cool—Any temperature between 8° C and 15° C (46°-59° F). An article

that requires cool storage, alternatively may be stored in a

refrigerator, unless otherwise specified by the individual USP

monograph.

* Room Temperature—The temperature prevailing in a working area.

* Controlled Room Temperature—A temperature maintained

thermostatically that encompasses the usual and customary working

environment of 20° C to 25° C (68°-77° F) that allows for brief

deviations between 15° C and 30° C (59°-86° F) that are experienced in

pharmacies, hospitals, and warehouses. Articles may be labeled for

storage at " controlled room temperature " or at " up to 25° " , or other

wording. An article for which storage at Controlled room temperature

is directed may, alternatively, be stored in a cool place, unless

otherwise specified in the individual monograph or on the label. (See

the entire revised definition of Controlled Room Temperature in the

Ninth Supplement to USP XXII-NF XVII.)

* Warm—Any temperature between 30° C and 40° C (86°-104° F).

* Excessive Heat—Any temperature above 40° C (104° F).

* Protection from Freezing—Where, in addition to the risk of breakage

of the container, freezing subjects an article to loss of strength or

potency, or to destructive alteration of its characteristics, the

container label must bear an appropriate instruction to protect the

article from freezing

4. The water-soluble vitamins are:

a. B and C.

b. B and D.

c. A and B.

d. A and D.

It's oft times easier to remember the least number of things. In this

case, the OIL soluble vitamins are A, D, E, K. Since D and A are in

answers b, c, and d, that means option a is the answer.

5. Pseudoephedrine would be contraindicated in a patient with:

a. allergic rhinitis.

b. a history of hypertension.

c. a history of urinary incontinence.

d. infection.

Pseudoephedrine is a sympathomimetic. Since it can act on some of the

same receptors a s epinephrine. It can increase heart-rate and

increase blood pressure. So if someone has a history of hypertension,

you would not want to use Pseudoephedrine with them without the

patient discussing it with their doctor first. So the answer is

option B.

6. A patient presents the following prescriptions from a primary physician:

K-Dur 20 mEq PO q.d.

Nitro-Dur 0.2 mg/hr Patch i top q.d. for 12 h

Nitrostat 0.4 mg SL p.r.n. cp

Theo-Dur 200 mg PO b.i.d.

Imdur 60 mg PO q.d.

and the following from a pulmonary specialist:

Azmacort Inhaler iii puffs b.i.d.

Uni-Dur 400 mg PO q.d.

Ventolin Inhaler ii puffs q.i.d. & 15 min pre-exercise

Medication duplication exists between:

a. Nitro-Dur and Uni-Dur.

b. Theo-Dur and Uni-Dur.

c. Imdur and Uni-Dur.

d. K-Dur and Uni-Dur.

K-Dur is a potassium supplement. Nitro-Dur and Nitrostat are both

nitroglycerin. Theo-Dur is a theophylline. Imdur is isosorbide

mononitrate (a vasodilator). Azmacort is triamcinolone, a steroid.

Uni-Dur is a theopylline. Ventolin is albuterol, a beta-agonist.

Duplication occurs between Nitro-Dur and NitroStat (since both are

nitroglycerin's) and Theo-Dur and Uni-Dur (since both are

Theophylline). So option B is the answer.

7. An order calls for Hytone 1% cream, Lotrimin 1% cream, aa q.s. How

many grams of Lotrimin cream would be needed to make a total of 60 g

of

cream?

a. 3 g

b. 6 g

c. 30 g

d. 60 g

aa q.s. means to use the amount needed to make the quantity specified,

which in this case is 60g. With this prescription, it's a 1:1 ratio,

so you'd need half of the quantity specified (which is 60g) of the

Lotrimin, or you would need 30g of the Lotrimin. So C is the answer.

8. Of the following, which medication is most likely to be associated

with development of photosensitivity?

a. Ampicillin

b. Tetracycline

c. Allopurinol

d. Clarithromycin

Tetracycline can be associated with photosensitivity. That's just

something that can happen with the tetracycline class. So B is the

answer.

9. An order specifies cefixime 75 mg q.d. for 10 days. If a 100 mg/5

mL suspension is used, the volume of each daily dose will be:

a. 2.75 mL

b. 3.75 mL

c. 6.70 mL

d. 7.50 mL

The math goes as:

100mg . . . . 75 mg

---------- = ----------------

5 ml . . . . . . ??

75mg * 5 ml / 100mg = 3.75 mL, so B is the answer.

Another way is to think that 75mg is 3/4 (0.75) of 100mg, so you're

taking 3/4 (0.75) of 5ml, so 5 * 0.75 = 3.75. (That's more in the UIL

Number Sense logic.)

10. Patients with opioid allergies should avoid taking:

a. aspirin.

b. morphine.

c. tramadol.

d. ketorolac

Morpine is the only one in the list that is an opiod. So someone with

opiod allergies should not take morphine. The others can all be used

for anti-inflammatory and pain relief properties if not

contra-indicated.
