Bone immobilization should always follow the?
* Pott’s rule:*
-If a long bone is broken, the immobilizing dressing should involve the given bone and two adjacent joints
-If a joint is damaged, the immobilizing dressing should involve the given joint and both bones forming it
Antipyretics MOA
cause the hypothalamus to override a prostaglandin-induced increase in temperature.
Antipyretics: example
-salicylates (eg, sodium salicylate and acetylsalicylic acid),
-ibuprofen, nonsteroidal anti-inflammatory drugs (NSAIDs),
-para-aminophenol derivative acetaminophen
Hypovolemic shock is a
generalized state of ischemia in the body when the body’s cells do not receive enough oxygen as a result of blood loss or transfer to other cavities in the body.
Hypovolemic shock resulting from blood loss is called
hemorrhagic shock
An orthostatic drop in blood pressure of _____mmHg and a concomitant increase in heart rate of ______ indicates what ?
An orthostatic drop in blood pressure of** ≥10 mmHg** and a concomitant increase in heart rate of** ≥20/min** indicates hypovolemia.
Loss of blood up to ____ is usually accompanied by ___.
Loss of blood up to 1500 ml is usually accompanied by** anxiety.**
The loss of half of total blood volume (_______ml) is associated with _______ disturbances of _______.
** (2000–2500 ml)** is associated with quantitative disturbances of** consciousness.**
Assuming an adult’s blood volume of 5 liters, the loss of **750ml of blood **is ____% of the circulating blood
Assuming an adult’s blood volume of 5 liters, the loss of **750ml of blood **is **15% **of the circulating bloodv
ATLS guidelines that break down the shock according to the percentage of
Class 1 shock loss of less than 15% of blood
- no symptoms
ATLS guidelines that break down the shock according to the percentage of
Class 2 shock loss of 15%-30% of blood
- increase in heart rate
ATLS guidelines that break down the shock according to the percentage of
Class 3 shock loss of 31%-40% of blood
- increase in heart rate and decrease in pressure, moderate increase in respiratory rate and decrease in diuresis.
ATLS guidelines that break down the shock according to the percentage of
Class 4 shock loss of more than 40% of blood
- a significant increase in heart rate and a decrease in pressure, an increase in respiratory rate, a significant decrease in diuresis.
Hypothermia is a condition in which the internal body temperature falls below ___ ° C.
**35 ° C. **
Classification of hypothermia distinguishes 5 stages of this condition
1 ° - mild hypothermia -
32-35 ° C
Classification of hypothermia distinguishes 5 stages of this condition
2 ° - Moderate hypothermia -
28-32 ° C
Classification of hypothermia distinguishes 5 stages of this condition
3 ° - Severe hypothermia -
24-28 ° C
Classification of hypothermia distinguishes 5 stages of this condition
4 ° - Cardiac arrest or hypoperfusion state
<24 ° C
Classification of hypothermia distinguishes 5 stages of this condition
5 ° - Death due to irreversible cooling of the body
<13.7 ° C
Cooling the body reduces ?
Oxygen demand (6% for every 1 ° drop in core body temperature).
Hypothermia reduces ?
body’s sensitivity to medication .
in case of hypothermia are warming the patient and performing chest compressions in a ratio of 30: 2. After reaching the body temperature of ____ ____, we start to administer drugs, remembering?
30 degrees, we start to administer drugs, -remembering that the time interval between two doses should be doubled
**Ventricular Tachycardia **
The ECG shows broad QRS tachycardia of ventricular origin.
The ECG record shows wide QRS complexes and the absence of a P wave.
Tachycardia is the result of the activity of the ventricular ectopic focus triggering high-frequency beats or is formed in the reentry mechanism.
** assystolia** - no electrical activity of the heart and no contractile activity of the heart. It should be distinguished from pseudo-asystole, which is caused by technical problems of the ECG recording equipment, poor adhesion of electrodes to the skin or errors in the examination technique, there is a systolic function of the heart.
