Cardiac arrhytmias - Study guides, Class notes & Summaries

1. Following A. Electrolyte inephrine (Levophed) administration, it is essential to the nurse to assess: A. Electrolyte status. B. Color and temperature of toes and fingers. C. Capillary refill. D. Ventricular arrhythmias. Correct Answer: B. Color and temperature of toes and fingers. Because decreased perfusion is a side effect of norepinephrine (Levophed), the nurse must check circulation frequently. Vasoconstriction secondary to alpha1 stimulation can result in reflex bradycardia via ...

narrow pulse pressure vs wide pulse pressure - narrow - aortic stenosis wide - aortic regurg Heart blocks - 1st - long PR 2nd 1 - progressivly longer pr, then dropped 2nd 2 - randomly dropped, inconsistent ps 3rd - no relationship between p and QRS, but ps consistent Emergent referral - MI, acute regurg, severe HTN, a-fib with rapid ventricular rate, pulmonary edema, new onset heart faliure causes of dialted cardiomyopathy - thiamine def, alcohol, myocarditis, cocaine, herion, peripartum...

Symptomatic therapy is? a. Using the substances which the organism is not able to produce in sufficient amounts b. Destroying the ethiological agent causing disease (antibodies against bacteria) c. Treating the symptoms d. Using very low drug concentrations (subliminal doses) for treating diseases c With regard to drug- receptor binding: a. A competitive antagonist has no intrinsic activity b. A partial antagonists has less receptor affinity than a full agonist c. KD (the dissociation c...

Furosemide (Lasix) Fluid Volume Excess correct answers Classification: diuretic Purpose: inhibits the reabsorption of sodium and chloride from the loop of Henle and distal renal tubule. Increases renal excretion of water, sodium, chloride, magnesium, potassium, and calcium. Effectiveness persists in impaired renal function. SDR: PO: (Adults) 20-80 mg/day as a single dose initially, may repeat in 6-8 hr Route: PO, IV, IM Side Effects: F and E: dehydration, hypocalcemia, hypochloremia,...

Ventricular arrhythmias. Correct Answer: B. Color and temperature of toes and fingers. Because decreased perfusion is a side effect of norepinephrine (Levophed), the nurse must check circulation frequently. Vasoconstriction secondary to alpha1 stimulation can result in reflex bradycardia via the barorece...
