Treatment of obstructive pulmonary disorders is aimed at:
blocking the effects of the immune and inflammatory systems.
opening the conducting airways or decreasing the effects of inflammation.
blocking the autonomic reflexes that alter respirations.
altering the respiratory membrane to increase the flow of oxygen and carbon dioxide.
Your patient has been maintained on theophylline for many years and has recently taken up smoking. The theophylline levels in this patient would be expected to:
rise because nicotine prevents the breakdown of theophylline.
stay the same because smoking has no effect on theophylline
fall because substances in cigarettes stimulate liver metabolism of theophylline.
rapidly reach toxic levels.
A child with repeated asthma attacks may be treated with which drugs? select 3
A leukotriene receptor antagonist
A beta-blocker
An inhaled corticosteroid
An inhaled beta-agonist
A surfactant
A nurse assessing a patient with HF would expect to find
an MI.
congestion in the blood vessels.
cardiac arrest.
a pulmonary embolism.
A nurse is preparing to administer a prescribed cardiac glycoside to a patient based on the understanding that this group of drugs acts in which way?
They block the renin–angiotensin system.
They block the parasympathetic influence on the heart muscle.
They block the sympathetic nervous system.
They affect intracellular calcium levels in the heart muscle.
A nurse is about to administer Lanoxin to a patient whose apical pulse is 48 beats/min. He or she should
administer the drug and notify the prescriber that the heart rate is low.
retake the pulse in 1 hour and withhold the drug if the pulse is still less than 60 beats/min.
retake the pulse in 15 minutes and give the drug if the pulse has not changed.
withhold the drug and notify the prescriber that the heart rate is below 60 beats/min.
How does ivabradine (Corlanor) work in the body?
Reduces heart rate by inhibiting action potentials at the SA node
Slows influx of calcium to decrease force of contraction
Blocks beta-receptors to slow the heart rate
Slows influx of calcium and relaxes blood vessels
Antiarrhythmic drugs alter the action potential of the cardiac cells. Because they alter the action potential, antiarrhythmic drugs often
cause new arrhythmias.
cause HF.
alter blood flow to the kidney.
cause electrolyte disturbances.
A patient who is receiving an antiarrhythmic drug needs
an antidepressant to deal with psychological depression.
frequent blood tests, including drug levels.
constant cardiac monitoring until stabilized.
dietary changes to prevent irritation of the heart muscle.
Prinzmetal angina occurs as a result of
a ventricular arrhythmia.
decreased venous return to the heart.
electrolyte imbalance.
a spasm of a coronary vessel.
Nitrates are commonly used antianginal drugs that act to
increase the preload on the heart.
dilate veins to increase the delivery of oxygen through those vessels.
increase the afterload on the heart.
decrease venous return to the heart, decreasing the myocardial workload.
Warfarin, an oral anticoagulant, acts
to directly prevent the conversion of prothrombin to thrombin.
to decrease the production of vitamin K clotting factors in the liver.
as a catalyst in the conversion of plasminogen to plasmin.
mmediately, so it is the drug of choice in emergency situations.
Heparin reacts to prevent the conversion of prothrombin to thrombin. Heparin
has its effects reversed with the administration of protamine sulfate.
takes about 72 hours to have a therapeutic effect.
is available in oral and parenteral forms.
has its effects reversed with the injection of vitamin K.
The low-molecular-weight heparin of choice for preventing DVT after hip replacement therapy is
betrixaban.
fondaparinux.
heparin.
enoxaparin.
