Online Schools of Nursing - Getting A Nursing Degree
Earning a nursing degree from online schools of nursing is becoming more and more popular. The flexibility and versatility these online nursing schools offer poses a lot of benefits.
Those looking to get a nursing degree can definitely take advantage of all the benefits online schools of nursing have to offer.
When earning a nursing degree online, you basically complete the non-clinical courses because clinical and laboratory classes
must be completed in person at a medical facility also operated by the online school of nursing. It is important to know that there are no online nursing programs that allow you to fully complete the degree online. Nevertheless, it is one good way to become a registered or practical nurse.
To find online nursing schools such as online practical nursing schools, you need to do a little research online. There are many websites offering online nursing courses. In fact, even online nursing PHD programs are available on the Internet. On Google or even on other reliable search engines, type the keywords that will help you find the online nursing schools you would like to attend. At the very least, you can type the words "online nursing degree" or "nursing degree online". You may also type the name of your city or state that you would like your nursing program to be in. The search engine will show you results with links to many online nursing schools. Check out some of these sites to see in detail what they offer and find out if their offerings match what you are looking for. There are some things that you consider when choosing the online school to attend to.
First and foremost, find out if the nursing program allows you to work at your own pace or the one that follows the school's schedule. A program that allows you to work at your own pace will allow you to finish or complete the work at a schedule or pace that suits you. However, there are many nursing programs structured like a traditional school or college. You should also find out the date when you can start. Some online schools for nursing have rolling enrollment which means that you can start at any date you prefer. Others designate a starting date.
You should also check if the online school has an academic advisor. It is a good idea to settle for one that assigns an academic advisor for each student because the advisor will help and work with students closely to help in planning out the course of study. An academic advisor also helps students keep on tract, connects with the students online, and coordinates with the students' clinical classes.
You should also check the costs of the nursing program because not all schools have the same charges. A thorough search of programs will help you land on the most affordable yet right online school for you. It is also good if you can find out if the school offers financial assistance. Many online nursing programs offer assistance and it is a good idea to take advantage of this financial help.
Once you have completed your research, you can narrow your choices of online schools of nursing down to a few until you land on the best one.

Dense Doctors
That title may sound a bit harsh. I know that our doctors are very intelligent when it comes to medicine.
But apart from that they seem to know sweet fuck all.
This is especially true when it comes to what is going on in the wards. It is true in regards to Nursing. If Nursing care goes bad medical orders do not get carried out and patients do not get monitored. In short the doctor's whole plan of care goes out the fucking window.
You would think that they would be a little more......well.....interested.
But no. They are delusional.
This is what I have learned about doctors in over a decade of Nursing.
1. They think all nurses are the same person or clones of the same person with a hive mind.
For example, if the Nurse on the shift before you missed something, it's your ass if you are the one on duty when doc graces your ward with his presence. If you are forced to float to a specialty you never worked or trained in before the doctors expect you to telepathically mind link with absent Nurses who have experience that area the minute you arrive on the ward They will not bother to write their orders or give you a heads up about things you need to know and wouldn't know unless you have experience there. They won't bother with any of that yet they'll go apeshit later when you forgot to remind them to prescribe something. Remember that they think Nurses are all the same drone with a hive mind who know each Doctors' individual ways.
2. They have no idea how to implement their own orders, or how time consuming and complex it is to implement their own orders.
Don't even get me started on the bullshit with the IV meds....both getting a hold of them and actually preparing them. Or fighting with pharmacy, equipment library and path lab. No Doctor they do not just keep everything on the ward for us. No they do not keep chest tube kits in a place where we can get them etc etc etc.
3. They have no idea how to work the system as a result of the Nurses doing it for them.
They don't understand why things don't happen instantly. For example, all RN's know it takes 6 weeks to get a patient into a Nursing home and that nothing can be done to speed this process up. Yet day after day the medical consultant walks in the very afternoon after he wrote that 90 year old Mabel can be discharged that morning and wants to know why she is still on the ward. Then he goes on a rant about how the Nurses can't be arsed to discharge patients. I could go on and on about this one, there are thousands of examples.
4. The saddest thing I learned about doctors and the crux of this post is that doctors are not able to distinguish between Nurses and ward assistants.
There are many times I am running my ass off trying to give a 150 IV meds all due now whilst the HCA's/cadets/auxiliaries are hanging out at the Nurse's station. The few jobs they can do are complete. They cannot help with the large proportion of the workload that only an RN can handle. Many doctors will walk onto a ward, take a look at the assistants hanging out at the station and exclaim "The Nurses don't seem to busy today". Dickhead. I am the only Nurse, and I am on my knees completely overwhelmed. What the assistants are doing (or not doing) is in no way indicative of how busy the Nurses are! Assistants are not Nurses.
Sometimes I will be 3 hours behind getting much needed drugs into patients and managing other patient problems and some young doctor will stroll onto the ward and ask me to hold an arm for him so that he can draw some ABGs. For god's sake, grab one of the assistants hanging around the Nurse's station for that. That is something they can actually do. Don't delay Mrs. Smith's pain relief any longer by causing me to stop and hold an arm!! It's not like the care assistants can give the meds and handle the Nurse stuff while I am tied up holding an arm for you!
A doctor walked onto my ward and wrote some orders for IV fluids and IV antibiotics for a patient with Pneumonia. As the only Nurse for all of those patients I was tied up and didn't see him arrive or know he wrote any orders. He handed the chart with his orders to a care assistant and left the ward. The care assistant has no idea about orders etc. She put the chart down on the station where it got immediately buried. And she said nothing to me. I had 25 patients that day (a staffing ratio no Nurse can function well with) and it was taking a hell of a lot of time to see everyone and process their orders. It was 3 hours before (by luck) I found the chart and the orders. Patient was in septic shock by that point. Doctors, you need to tell the actual Nurse about these things, not some underpaid teenage assistant that you have confused with Nursing staff.
Then there was the doctor who started yelling at me for having 4 bays full of patients rather than one!! "That is too many patients! You should have one bay per Registered Nurse". Yes Sherlock, no shit. I appreciate the fact that you have actually noticed that the RN ratios on NHS wards are horrible and dangerous and that this has a dire effect on patient care. But what the hell would possess you to think that they Nurses on the ground have any say in how we are staffed or how many patients we have? Even the ward Sisters are not allowed to have a say in how their wards are staffed. Duh.
I could go on and on. These doctors are clueless about what is going on with Nursing care and RN staffing on the wards. And frankly, I am getting sick of it.
My cousin in law is a doctor in the USA. He is not as dense as his colleagues here. If he finds out that his patients' RN's are being forced to take on more than 4-6 patients at a time he gets on the phone to MANAGEMENT and starts screaming. He tells management that he will have his patients pulled out of there by the end of the day and admitted somewhere else if they do not staff the facility properly.
He doesn't care how compassionate or knowledgeable or wonderful the Nurses are in that place. He knows that with poor staffing ratios that they cannot function even if they are wonderful. The facility would lose a ton of money if he pulled his patients out of there so they wouldn't dare short staff the place. They did it once, never again. Managers of hospitals all over the world think that intentional RN short staffing is the way to save cash.
He is a good doctor, and understands that without decent Nursing care delivered by RN's the patients are screwed. He understands that there will be nothing in the way of decent Nursing care in a place where Nurses are denied resources and safe staffing ratios. And he acts on it.
But it seems it is too much to ask for UK doctors to even understand what a Nurse is, let alone stand up for them. They haven't even grasped the notion that these Nurses are taking on too many patients to be able to care for anyone properly, and that they are being forced into a position where they cannot spend two minutes demonstrating compassion without risking a disciplinary for not filling in paperwork. Too bad.

The 12 Cranial Nerves
There are 12 pairs of cranial nerves. These nerves arise from the brain and brain stem, carrying motor and or sensory information.
Cranial nerve I : Olfactory nerve
The olfactory nerve is composed of axons from the olfactory receptors in the nasal sensory epithelium. It carries olfactory information (sense of smell) to the olfactory bulb of the brain. This is a pure sensory nerve fiber.
Cranial nerve II: Optic nerve
The optic nerve is composed of axons of the ganglion cells in the eye. It carries visual information to the brain. This is a pure sensory nerve fiber. This nerve travels posteromedially from the eye, exiting the orbit at the optic canal in the lesser wing of the sphenoid bone. The optic nerves join each other in the middle cranial fossa to form the optic chiasm.
Cranial nerve III: Oculomotor nerve
The oculomotor nerve is composed of motor axons coming from the oculomotor nucleus and the edinger-westphal nucleus in the rostral midbrain located at the superior colliculus level. This is a pure motor nerve. It provides somatic motor innervation to four of the extrinsic eye muscles: the superior rectus, inferior rectus, medial rectus, and the inferior oblique muscles. It also innervates the muscles of the upper eyelid and the intrinsic eye muscles (the pupillary eye muscle.) Together, CN III, CN IV and CN VI control the six muscles of the eye.
Cranial nerve IV: Trochlear nerve
The trochlear nerve provides somatic motor innervation to the superior oblique eye muscle. This cranial nerve originates at the trochlear nucleus located in the tegmentum of the midbrain at the inferior colliculus level and exits the posterior side of the brainstem. It is also a pure motor nerve fiber.
Cranial nerve V: Trigeminal nerve
The trigeminal is the largest cranial nerve . It provides sensory information from the face, forehead, nasal cavity, tongue, gums and teeth (touch, and temperature) and provides somatic motor innervation to the muscles of mastication or “chewing”.
This cranial nerve has 3 branches: the ophthalmic, maxillary and mandibular branches.
It is composed of both sensory and motor axons. The sensory fibers are located in the trigeminal ganglion and the motor fibers project from nuclei in the pons.
Cranial nerve VI: Abducens nerve
The abducens nerve carries somatic motor innervation to one of the extrinsic eye muscles, the lateral rectus muscle. It is another pure motor nerve fiber and originates from the abducens nucleus located in the caudal pons at the facial colliculus level.
Cranial nerve VII: Facial nerve
The facial nerve carries somatic motor innervation to the many muscles for facial expression. It carries sensory information form the face (deep pressure sensation) and taste information from the anterior two thirds of the tongue. It arises at the pons in the brainstem and it emerges through openings in the temporal bone and stylomastoid foramen and has many branches. It is composed of both sensory and motor axons.
Cranial nerve VIII: Vestibulocochlear nerve
The vestibulocochlear nerve innervates the hair cell receptors of the inner ear. It carries vestibular information to the brain from the semicircular canals, utricle, and saccule providing the sense of balance. It also carries information from the cochlea providing the sense of hearing. This cranial nerve branches into the Vestibular branch (balance) and the cochlear branch (hearing). The cochlear fibers originate from the spiral ganglion. It is pure sensory nerve fiber.
Cranial nerve IX: Glossopharyngeal nerve
The glossopharyngeal nerve innervates the pharynx (upper part of the throat), the soft palate and the posterior one-third of the tongue. It carries sensory information (touch, temperature, and pressure) from the pharynx and soft palate. It carries taste sensation from the taste buds on the posterior one third of the tongue. It provides somatic motor innervation to the throat muscles involved in swallowing. It provides visceral motor innervation to the salivary glands. This cranial nerve also supplies the carotid sinus and reflex control to the heart . It is composed of both sensory and motor axons and originates from the nucleus ambiguous in the reticular formation of the medulla.
Cranial nerve X: Vagus nerve
The vagus nerve consists of many rootlets that come off of the brainstem just behind the glossopharyngeal nerve. The branchial motor component originates from the nucleus ambiguous in the reticular formation of the medulla. The visceral component originates from the dorsal motor nucleus of the vagus located in the floor of the fourth ventricle in the rostral medulla and in the central grey matt er of the caudal medulla. It is the longest cranial nerve
innervating many structures in the throat, including the muscles of the vocal cords, thorax and abdominal cavity. It provides sensory information (touch, temperature and pressure) from the external auditory meatus (ear canal) and a portion of the external ear. It carries taste sensation from taste buds in the pharynx. It also provides sensory information from the esophagus, respiratory tract, and abdominal viscera (stomach, intestines, liver, etc.). It provides visceral motor innervation to the heart, stomach, intestines, and gallbladder. It is part of the ANS, the parasympathetic branch. It is composed of both sensory and motor axons. Other parasympathetic ganglia include CN III , CN VII and CN IX .
Cranial nerve XI: Spinal Accessory nerve
The spinal accessory nerve has two branches. The cranial branch provides somatic motor innervation to some of the muscles in the throat involved in swallowing. This cranial branch is accessory to CN X, originating in the caudal nucleus ambiguous, with the fibers of the cranial root traveling the same extracranial path as the branchial motor component of the vagus nerve. The spinal branch provides somatic motor innervation to the trapezius muscles, providing muscle movement for the upper shoulders head and neck. It is pure motor nerve fiber.
Cranial nerve XII: Hypoglossal nerve
The hypoglossal nerve provides somatic motor innervation to the muscles of the tongue. This pure motor nerve originates from the hypoglossal nucleus located in the tegmentum of the medulla.

Normal Heart Sounds
Heart Sounds
The heart sounds are the noises (sound) generated by the beating heart and the resultant flow of blood through it. This is also called a heartbeat. In cardiac auscultation, an examiner uses a stethoscope to listen for these sounds, which provide important information about the condition of the heart.
In healthy adults, there are two normal heart sounds often described as a lub and a dub (or dup), that occur in sequence with each heart beat. These are the first heart sound (S1) and second heart sound (S2), produced by the closing of the AV valves and semilunar valves respectively. In addition to these normal sounds, a variety of other sounds may be present including heart murmurs, adventitious sounds, and gallop rhythms S3 and S4.
Heart murmurs are generated by turbulent flow of blood, which may occur inside or outside the heart. Murmurs may be physiological (benign) or pathological (abnormal). Abnormal murmurs can be caused by stenosis restricting the opening of a heart valve, resulting in turbulence as blood flows through it. Abnormal murmurs may also occur with valvular insufficiency (or regurgitation), which allows backflow of blood when the incompetent valve closes with only partial effectiveness. Different murmurs are audible in different parts of the cardiac cycle, depending on the cause of the murmur.
Normal Heart Sounds
Normal heart sounds are associated with heart valves closing, causing changes in blood flow.
S1
The first heart tone, or S1, forms the "lubb" of "lubb-dub" or "lubb-dup" and is composed of components M1 and T1. Normally M1 precedes T1 slightly. It is caused by the sudden block of reverse blood flow due to closure of the atrioventricular valves, i.e. mitral and tricuspid, at the beginning of ventricular contraction, or systole. When the ventricles begin to contract, so do the papillary muscles in each ventricle. The papillary muscles are attached to the tricuspid and mitral valves via chordae tendineae, which bring the cusps or leaflets of the valve closed (chordae tendineae also prevent the valves from blowing into the atria as ventricular pressure rises due to contraction). The closing of the inlet valves prevents regurgitation of blood from the ventricles back into the atria. The S1 sound results from reverberation within the blood associated with the sudden block of flow reversal by the valves.[1] If T1 occurs more than slightly after M1, then the patient likely has a dysfunction of conduction of the right side of the heart such as a Right bundle branch block.
S2
The second heart tone, or S2, forms the "dub" of "lubb-dub" or "lubb- dup" and is composed of components A2 and P2. Normally A2 precedes P2 especially during inspiration when a split of S2 can be heard. It is caused by the sudden block of reversing blood flow due to closure of the aortic valve and pulmonary valve at the end of ventricular systole, i.e. beginning of ventricular diastole. As the left ventricle empties, its pressure falls below the pressure in the aorta, aortic blood flow quickly reverses back toward the left ventricle, catching the aortic valve pocketlike cusps and is stopped by aortic (outlet) valve closure. Similarly, as the pressure in the right ventricle falls below the pressure in the pulmonary artery, the pulmonary (outlet) valve closes. The S2 sound results from reverberation within the blood associated with the sudden block of flow reversal.
Splitting of S2 normally occurs during inspiration because the decrease in intrathoracic pressure causes more blood to be delivered to the right heart, thereby prolonging contraction and delaying closure of the pulmonic valve. A widely split S2 can be associated with several different cardiovascular conditions, including right bundle branch block and pulmonary stenosis.(wikipedia)
Assessing Lung Sound
To auscultate lung sounds, move the diaphragm of your stethoscope according to the numbers on the corresponding diagram.
There are three normal breath sounds :
- (B) Bronchial Breath Sounds - loud, harsh, hight pitched
Heard over trachea, bronchi (betwen clavicles and midsternum), and over main bronchus. - (BV) Bronchovesicular Breath Sounds - blowing sounds, moderate intensity and pitch.
Heard over large airways, on either side of sternum, at the Angle of Louis, and betwen scapulae. - (V) Vesicular Breath Sounds - soft breezy quality, low pitched.
Heard over the peripheral lung area, heard at best of base lungs.
