Carnegie Right Heart

Right heart Quiz prep

You are inflating the balloon on a Swan-Ganz catheter. You feel no resistance as you inflate and the syringe plunger does not passively spring back upon release. You should: Aspirate 1.5 cc's (pull blood out because balloon has burst) and tape the port so no one else tries to inflate the ballon; notify the physician
You are advancing a Swan Ganz Catheter into an elderly lady with a dilated right heart. with balloon inflated the catheter passes easily from the IVC and RV but won't pass into the PA. Additional maneuvers include: Have her inhale deeply and cough (this applies negative pressure, pulls more blood closer to PA and cough may push it into PA)

What is the maximum number of sublingual notes nitroglycerin tablets to be taken for an attack of angina pectoris? 3
1 inch of nitro paste went mint provides how much nitroglycerin? 15 milligrams
The transdermal nitro patch provides 2.5 - 14 milligrams per 24 hours
True or false a patient taking sublingual nitroglycerin should be instructed to take a second tablet after a period of 5 minutes if the pain is not relieved. True
True or false apply a transdermal patch of nitroglycerin to any non hairy area of the body except the distal arms and legs True
True or false always use lactated ringers to mix a nitro drip False, only for saline
Nitrate tolerance involves activation of what compensatory mechanisms? Renin angiotensin aldosterone system, sympathetic nervous system
Your patient mr. Titus a drum, is taking nitroglycerin, verapamil hydrochloride (calinl and warfarin sodium (coumadin). He is also taking an over-the-counter analgesic containing aspirin to relieve persistent, mild headache. What could be the cause? Aspirin may potentiate the coumadin and could increase the risk of cerebral bleeding; the nitroglycerin may be causing the headaches
True or false amyl nitrate is associated with increased BP False
