Discuss the different types of headaches, the possible causes of each, and how to distinguish a harmless headache from a potenti

Law Incorporation [45]

Answer:

A. One of the most common complaints you will hear from your patients in terms of pain is headache.

1. Headache can be a symptom of another condition or it can be a neurologic condition on its own.

2. Only a small percentage of headaches are caused by a serious medical condition.

3. Most headaches are harmless and do not require emergency medical care.

4. Sudden, severe headache, however, requires assessment and transport.

a. If more than one patient reports headache, consider carbon monoxide poisoning.

B. Tension headaches, migraines, and sinus headaches are the most common types.

1. These are not medical emergencies.

2. Tension headaches are the most common.

a. These headaches are caused by muscle contractions in the head and neck and are attributed to stress.

b. The pain is usually described as squeezing, dull, or as an ache.

C. Migraine headaches are the second most common type of headache.

1. They are thought to be caused by changes in the blood vessel size in the base of the brain.

2. The pain is usually described as pounding, throbbing, and pulsating.

3. Migraines are often associated with visual changes such as flashing lights or partial vision loss.

4. The patient will often have nausea and vomiting.

5. Migraine headaches can last for several days.

D. Sinus headaches are caused by pressure that is the result of fluid accumulation in the sinus cavities.

1. Patients may also have coldlike signs and symptoms of nasal congestion, cough, and fever.

2. Prehospital emergency care is not required.

E. Serious conditions that include headache as a symptom are hemorrhagic stroke, brain tumors, and

meningitis.

1. You should be concerned if the patient complains of a sudden-onset, severe headache or a sudden

headache that has associated symptoms.

2. You should suspect a stroke in patients with a severe headache, seizures, and AMS.

3. Your patient assessment should include asking the patient if he or she has experienced any recent head trauma.

Someone explain classical conditioning from Ivan Pavlovym to me please???????

pashok25 [27]

Answer:

Discovered by Russian physiologist Ivan Pavlov, classical conditioning is a learning process that occurs through associations between an environmental stimulus and a naturally occurring stimulus.

Explanation:

The most important thing to remember is that classical conditioning involves automatic or reflexive responses, and not voluntary behavior (that's operant conditioning, and that is a different post). What does this mean? For one thing, that means that the only responses that can be elicited out of a classical conditioning paradigm are ones that rely on responses that are naturally made by the animal (or human) that is being trained. Also, it means that the response you hope to elicit must occur below the level of conscious awareness - for example, salivation, nausea, increased or decreased heartrate, pupil dilation or constriction, or even a reflexive motor response (such as recoiling from a painful stimulus). In other words, these sorts of responses are involuntary.

The basic classical conditioning procedure goes like this: a neutral stimulus is paired with an unconditional stimulus (UCS). The neutral stimulus can be anything, as long as it does not provoke any sort of response in the organism. On the other hand, the unconditional stimulus is something that reliably results in a natural response. For example, if you shine a light into a human eye, the pupil will automatically constrict (you can actually see this happen if you watch your eyes in a mirror as you turn on and off a light). Pavlov called this the "unconditional response." (UCR)

As soon as the neutral stimulus is presented with the UCS, it becomes a conditional stimulus (CS). If the CS and UCS always occur together, then the two stimuli would become associated over time. The response that was initially produced in response to the UCS would also be produced in response to the CS, even if it was presented alone. Pavlov called this the "conditional response." (CR)

To make this a bit more concrete, we'll use Pavlov's dogs as an example. Before learning took place, the dogs would reliably salivate (UCR) when given meat powder (UCS), but they gave no response to the ringing of a bell (neutral). Then Pavlov would always ring a bell just before he would present the dogs with some meat powder. Pretty soon, the dogs began to associate the sound of the bell with the impending presence of meat powder. As a result, they would begin to salivate (CR) as soon as they heard the bell (CS), even if it was not immediately followed by the meat powder (UCS). In other words, they learned that the bell was a reliable predictor of meat powder. In this way, Pavlov was able to elicit an involuntary, automatic, reflexive response to a previously neutral stimulus.
