Cardiac NCLEX Question Answers
Here are the answers to the sample questions. If anything seems fishy, so to speak, please let me know!
From these lab results alone, no further course is indicated. A HDL above 60 mg/dl is considered good, as well as an LDL level below 100 mg/dl.
Vitamin K is an antagonist to Warfarin (Coumadin).
The symptoms combined with the diastolic murmur point to mitral valve stenosis. Dowager's is a term associated with a hump and osteoporosis.
The sinoatrial node generates 60-100 electrical impulses per minute.
Though the procedure protocol can vary depending on where it is done, typically cardiac catheterization requires fasting for a longer period beforehand.
The term neointimal hyperplasia refers to the regrowth of tissue after a procedure due to aggravation. In angioplasties, this can result in the vessel being blocked again despite initial success in clearing space.
A transcutaneous pacemaker can be used to temporarily control sinus bradycardia that presents with shock that doesn't respond to atropine.
In cardioversion, the heart still has a rhythm and so the shocks are synchronized. Defibrillation is done when there is no pulse such as ventricular fibrillation and is generally asynchronous.
A synchronous pacemaker is designed to activate "on-need." It helps the heart while attempting to interfere as little as possible.
This approach does not work in all cases, of course. Sometimes constant stimulation is needed.
Endocarditis can be caused by bacteria migrating from the mouth. Good dental hygiene can lower the risk.
