Hormones Flashcards
1
Q
Vasopressin (Pitressin):
- Functional Class
A
- Hormone (ADH), Vasopressor
2
Q
Vasopressin (Pitressin):
- Mechanism of action
A
- Possesses pressor and anti-diuretic properties.
- Increases nephron distal tube reabsorption of water.
- High doses act as a non-adrenergic vasoconstrictor by stimulation of smooth muscle receptors.
- Alt to epinephrine during CPR.
3

- Indications
A
- Cardiac Arrest
4
Q
Vasopressin (Pitressin):
- Contraindications

- Ischemic Heart Disease
- PVC’s
- 1st stage of labor
5
Q
Vasopressin (Pitressin):
- Dosage/Route
A
- 40 units IVP/IO (single dose only), replaces 1st or 2nd dose of epinephrine.
6
Q
Oxytocin (Pitocin)
- Functional Class
A
- Hormone
7
Q
Oxytocin (Pitocin)
- Mechanism Of Action
A
- Acts directly on myofibrils causing phasic contraction of the uterine smooth muscle, characteristic of normal delivery.
8
Q
Oxytocin (Pitocin)
- Inditactions
A
- Postpartum Hemorrhage
9
Q
Oxytocin (Pitocin)
- Contraindications
A
- Hypersensitivity
- Prior to delivery of the fetus; administration prior may cause:
> Fetal Hypoxia
> Asphyxia
> Dysrhythmias
10
Q
Oxytocin (Pitocin)
- Precautions
A

- Dysrhythmias
- Seizures
- Dyspnea
- Coma in Mother
- Intercanial Bleeding
- HTN, Anxiety, N/V
12
Q
Oxytocin (Pitocin)
- Interactions
A
- HTN when used w/ vasoconstrictors
13
Q
Oxytocin (Pitocin)
- Dosage/Route
A
- Bolus: 3-10 units IM
- Infusion: 10-20 units in 1000 mL via 60gtts/mL titrate to effect
14
Q
Glucagon (GlucaGen):
- Functional Class
A
- Hormone
15
Q
Glucagon (GlucaGen):
- Mechanism of Action:
A
- A protein secreted by Alpha cells of the Islets of Langerhans.
- Converts stored glycogen in the liver to glucose.
- Inhibits the synthesis of glucose to glycogen.
- Enhances conventional treatments for C+ blockers and Beta blockers OD by producing positive inotropic and chronotropic effects on the heart by stimulating glucagon specific receptors in myocardium. These receptors are not even effected by massive amounts of beta blockers, there by reversing hypotension and bradycardia.
