Myocardial infarction (heart attack or MI) ischemia lecture on the pathophysiology, ECG, nursing role, complications, signs and symptoms. This video on myocardial infarction will help students prepare for the NCLEX exam.
Licensed practical nurses (LPNs) and vocational nurses (LVNs) provide basic medical care, such as checking a patient's blood pressure. Duties of LPNs and LVNs vary, depending on their work setting and the state in which they work. For example, they may reinforce teaching done by registered nurses regarding how to help care for newborn infants, attend to the needs of inpatients, or collect laboratory samples for testing. Nurses must often be on their feet for much of the day. They are vulnerable to back injuries, because they may have to lift patients who have trouble moving in bed, standing, or walking.
LPNs and LVNs may be limited to doing certain tasks, such as feeding patients who cannot care for themselves, depending on the state where they work. For example, in some states, LPNs with proper training can give medication or start intravenous (IV) drips, but in other states LPNs cannot perform these tasks. State regulations also govern the extent to which LPNs and LVNs must be directly supervised. For example, an LPN may provide certain forms of care only with instructions from a registered nurse.
LPNs and LVNs must complete an accredited nurse training program. These programs award a certificate or diploma and typically take about 1 year to complete. They are commonly found in technical schools and community colleges, although some nursing programs may be available directly through hospitals. Practical nursing programs combine classroom learning in subjects such as nursing, anatomy, human physiology, biology, and pharmacology. Programs also include supervised clinical experience and hospital rotations.
After completing a state-approved educational program, prospective nurses can take the National Council Licensure Examination (NCLEX-PN). In all states, they must pass the exam to get a license and work as an LPN or LVN. For more information on the NCLEX-PN examination and a list of state boards of nursing, visit the National Council of State Boards of Nursing. LPNs and LVNs may choose to become certified in specialty areas such as gerontology and intravenous (IV) therapy.
Certification requirements include board certification. LPNs/LVNs must take and pass the National Council Licensure Examination. Once they have passed, they can obtain a certification allowing them to be placed on their state’s registry and work as an LPN in the United States. To keep your license current, you must take continuing education courses, and renew your license every few years. There are a fixed number of credits that each state requires, and if you work in a hospital facility, these courses may be offered on-site.
This section offers practice tests in several subject areas. Each of the following multiple-choice tests has 10 questions to work on. No sign-up required, just straight to the test.
Ask yourself if you can see yourself being a nurse, having daily contact with patients who may be elderly, ill, or recovering from surgery. Other patients may have physical or emotional disabilities, which can be challenging. While nursing classes and internships will prepare you well, certain innate qualities that you bring to bear will help you succeed as a nurse.
Nurses must relate well with other people, and the personal touches that a nurse adds to overall medial care can give one-on-one attention that patients remember the most.
In this video we will discuss sympathetic and parasympathetic pharmacology, which will include a discussion about sympathomimetics, parasympathomimetics, sympatholytics, and parasympatholytics drugs.
As a nurse, you'll want to be familiar with basic ekg/ecg interpretations, how to identify heart rhythms, P waves, T waves, PR intervasl, QRS complexes, PR segments, ST segments, J point, QT intervals, and so forth. In this video, Nurse Sarah breaks down EKG basics and gives examples of how to measure different parts of a 6-second EKG strip.
Checking blood sugar (glucose) using a glucometer device (glucose meter). Learn how to use true result blood glucose meter by taking your blood glucose. As a new diabetic or nursing student,you must learn the skill of using a lancet to obtain a blood sugar.
Lung anatomy and physiology of gas exchange in the lung alveoli during respiration. This lecture details the anatomy of the lungs and how gas exchange in the lungs takes place between carbon dioxide and oxygen. The lung is made up of many components that participant in gas exchange.
Most licensed practical and licensed vocational nurses (LPNs and LVNs) work full time, although about 1 in 5 worked part time in 2017. Many work nights, weekends, and holidays, because medical care takes place at all hours. They may be required to work shifts of longer than 8 hours. Employment of licensed practical and licensed vocational nurses (LPNs and LVNs) is projected to grow 12 percent over the next decade, faster than the average for all healthcare occupations.
A number of chronic conditions, such as diabetes and obesity, have become more prevalent in recent years. LPNs and LVNs will be needed to assist and care for patients with chronic conditions in nursing homes and other extended-care facilities. In addition, many procedures that once were done only in hospitals are now being performed outside of hospitals, creating demand in outpatient care centers.
With experience, licensed practical and licensed vocational nurses may advance to supervisory positions. Some LPNs and LVNs advance to other healthcare occupations. For example, an LPN may complete a LPN to RN education program to become a registered nurse.
