NR 283 EXAMINATION STUDY GUIDE 2026
COMPLETE QUESTIONS AND ANSWERS
◉ blood tests.
Answer: Serum Lipid Levels and CRP);
HDL shows the number of good lipoproteins, which transports
cholesterol away from the peripheral cells to the liver for excretion.
LDL shows the number of bad lipoproteins, which acts as a transport
of cholesterol from the liver to the cells.
C-reactive protein (CRP) identifies the amount of inflammation in
the body.
◉ angioplasty.
Answer: inserting a balloon to a narrow portion of the coronary
artery before inflating the balloon to restore blood flow
◉ stenting.
Answer: leaving a wire cage to support the recently opened section
of artery
◉ coronary artery bypass grafting surgery.
Answer: Most commonly performed surgery after
, formal cardiac catheterization to see if it will benefit the patient.
◉ cardiac dysrhythmia.
Answer: Abnormal heart rhythm
irregular or abnormal electrical signals that may cause the heart to
contract too quickly, too slowly, or in an abnormal direction
◉ sinoatrial node.
Answer: The pacemaker of the heart, located in the right atrium.
◉ causes of dysrhythmias.
Answer: fluid and electrolyte imbalances (especially potassium; also
calcium), fever, medication toxicity, stress, infection, hypoxemia,
injury to the heart itself
◉ how to treat dysrhytmias.
Answer: some require electricity to stop them, others may require a
pacemaker, sometimes medications are used
◉ how does potassium affect heartbeats?.
Answer: triggers and sends electrical impulses
(like the heart's battery)
