QuestionAnswer
Antiviral Agents Treats virus other than HIV (chickenpox, shingles, herpes, influenza) *impairs viral replication
Acyclovir (Zovirax) Antiviral agent *treats herpes *not curative, episodes may recur
Tamiflu Antiviral *Influenza A &B *Start within 2 days of symptom onset *Tx. BID for 5 days
Antiretroviral *used to treat HIV * reduces viral concentration
HAART highly active antiretroviral therapy *combination drug therapy
Zidovudine (AZT) (Retrovir) Antiretroviral (Nucleoside Reverse Transcriptase Inhibitor) (NRTI's) - improves T-cell counts - suppresses bone marrow
Indinavir (Crixavan) Antiretroviral (Pretease Inhibitors) (PI's) * increase CD4 cell count * risk or kidney stones, keep hydrated
Enfurirtide (Fuzeon) Antiretroviral (Fusion Inhibitor) * used in combination with other drugs * injectable, causes pain at injection site
T-cells (T-Lymphocytes) white blood cells (CD4 & CD8)
CD4 Counts & Percentages - lab test to see how well the antiviral is working & to monitor the immune system *below 200-250 or below 15% = increased risk for infection
Tx. requirements for Tuberculosis *compliance ESSENTIAL *6-12 months on drugs * 2-7 concurrent medications *Tx. of those living close or exposed
Isoniozid (INH) TB Drug - cidal/inhibits cell wall synthesis - side effects (numbess & tingling)
Rifampin (Rifadin) TB Drug - inhibits RNA synthesis - colors/stains secretions reddish/orange
Mycosis fungal infection *usually occurs in immunocompromised
Amphotericin B Antifungal Systemic Tx. *treats aspergillosis, blastomycosis, candida, coccidomycoses *horrible side effects, pre medicate
Nystatin (Nystat) Antifungal Superficial Tx. *vagina, skin, mouth *topical, oral suspension, lozenge, vag supp., topical cream *Oral suspension - swish 2 min
Chloroquine (Aralen) Antimalarial *parasitic infections
Metronidazole (Flagyl) Antiprotozoal ambicidal drug *causes metallic taste in mouth & dark colored urine *Toxoplasmosis = from cat feces
Antihelmintics very specific to specific worm *Dx. of exact worm is very important for correct Tx.
SNS Stim - Pupils Dilate
SNS Stim - Salvation Decreases
SNS Stim - Bronchi Dilate
SNS Stim - Heart Rate Increases
SNS Stim - GI Motility Decreases
SNS Stim - Bladder Detuser Contracts
SNS Stim - Urinary sphincter Contracts
SNS Stim - Glucose releases from liver Stimulated
SNS Stim - Insulin Release Increase or Decrease
SNS Stim - Uterus muscle contracts & relaxes
PSNS Stim - Pupils Constrict
PSNs Stim - Salvation Increases
PSNS Stim - Bronchi Contricts
PSNS Stim - Heart Rate Decreases
PSNS Stim - GI Motility Increases
PSNS Stim - Bladder Detuser Contracts
PSNS Stim - Urinary Sphincter Relaxes
Alpha 1 - Postsynaptic cells of SNS - Found in many organs, especially vascular smooth muscle - Vasoconstriction - Decreases secretions, decreases GI motility, urinary sphincter contracts, pregnant uterus contracts/relaxes, male sex organ - ejaculation)
Alpha 2 - Presynaptic nerve endings of SNS - Found in many organs, especially vascular smooth muscle - Vasodilation - Decreases secretions, decreases GI motility, urinary sphincter contracts, pregnant uterus contracts/relaxes, male sex organ - ejaculation
Beta 1 -Postsyanaptic cells of SNS - heart & kidneys - increases contractibility - Increases heart rate - Increases conduction - Increases renin release
Beta 2 - Postsynaptic cells of SNS - Resp. Tract, Liver, Muscle, Uterus - Bronchodilation - Vessel Dilation
Beta 3 - Adipose tissue, Gallbladder, Urinary Bladder - Brown Fat Tissue - Increased Fatty acid in blood - Regulate body weight - relaxes bladder muscle
Inotrope drug that affects cardiac contractibility (strengths & weakens)
Chromotrope drug that affects cardiac rate (speeds & slows)
Dromotrope drug that affects speed of AV conduction (speeds & slows)
Indications for Stimulating the SNS (Sympathomimetics) *Bronchodilators for asthma & related resp. conditions * Mydriatics in open angle glaucoma * Decongestants for nasal congestion * Opthalmics for ocular congestion * Cardiac medications for heart failure
Epinephrine Sympathomimetic Direct Acting -> Alphas & Beta 1 & 2 - Indications - Bronchoconstriction, COPD, Asthma, Analphyaxis - Side Effects - SNS stim, anxiety, angina, MI *Use caution with hypertension, EKG monitor & vitals q3-5 min
Anaphylaxis Tx. Epinephrine (EpiPen) *thigh should be used for injection *held in place for 5-10 seconds *Emergency care obtained ASAP *Single use injection
Norepinephrine (Levophed) Sympathomimetics Direct Acting -> Alphas & Betas 1 Indications - Hypotension Side Effects - SNS stim, extravasation, necrosis *Caution with hypertension, EKG monitor & vitals q3-5 min
Dobutamine (Dobutrex) Sympathomimetics Vasoactive Pressor -> Beta 1 Indications - cardiac decompression, hypotension Side Effects - SNS Stim, ventricular ectopy, increased cardiac output, angina *caution with hypertension, EKG monitor & q3-5 min vitals
Indications to BLOCK the SNS Alpha Receptors - headaches - women in labor - hypertensive clients - pts with IV drug extravasation
Phentolamine (Regitine) Alpha Blocker - dilates arterioles, decreases BP, Increases cardiac output Indications - Extravasation of vasodilators, Dx & Tx of pheochromocytoma *monitor vitals, watch urine output, EKG
Indications to BLOCK the SNS Beta Receptors - Angina, post MI, atrial/ventricular tacyarrthymias, hypertension, CHF - headaches - glaucoma
Propranolol (Inderal) Beta Blocker (blocks Beta 1 & 2) Indications - Angina, hypertension, arrhythmias, prevention of MI Side Effects -decrease heart rate, bronchoconstriction, fatigue, weakness, decreases BP, wheezing, decreases libido * oral & IV, take @ same time Qday

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
