Answer:
The answer to the question: velocity of blood is relatively constant as blood flows from the aorta towards the capillaries, would be, B: False.
Explanation:
One way to figure this one out is knowing that the velocity of the blood as it flows through the aorta, comes from the pumping strength of the heart. However, as the blood starts traversing the length of the different arteries, arterioles, and finally reached the capillaries, it encounter two things; first, the speed with which it was originally launched by the heart into the aorta, has already diminished as it moves away from the heart. Second, blood will encounter a series of barriers, not the least of which is resistance from the blood vessels themselves, that will lower the speed with which it will reach the capillares. And this is just as well, as capillaries are much more fragile than arteries themselves, their purpose actually being to serve as exchange points between the cardiovascular system and the different tissues of the body. Their structure is much thinner, and thus needs less speed, in order for exchanges to take place. This is why it is false.

Answer: c. OPQRST
Explanation:
OPQRST is an acronym that is very useful in the medical profession as it serves as a guide to diagnose patients and find out more about what the pain they are going through.
The acronym stands for;
- Onset - with what intensity did the pain hit. In other Has it progressed steadily or remained constant.
- Provocation or Palliation - have there been any external factors that aggravate the conditions?
- Quality - what type of pain it is. For instance is the pain sharp, crushing, dull, etcetera. Such a question would fall under here.
- Region and Radiation - Where is the pain located and does it remain there or radiate to other parts of the body as well.
- Severity - Just how heavily is the pain being felt. How severe is it. Usually a scale of 1 to 10 is used with 10 being excruciating pain and 0 being no pain at all.
- Time (History) - How long has the pain being going on. How often is such pain experienced if ever. The goal being to find out if it a recurring pain as well its current duration.
Diabetes complications have grown in recent years as the prevalence of the disease has increased.
A systematic review and meta-analysis of efficacy and safety of negative pressure:
- (1). A frequent diabetes consequence known as diabetic foot (DF) is hyperglycemia, which results in peripheral nerve and vascular lesions, dry and itchy skin on the feet, and eventually leads to ulcers that take a long time to heal and reduce patients' quality of life
- (2). Numerous novel techniques have been gradually implemented in the treatment of wounds as new medical therapies have emerged, guided by cytohistology and biochemistry.
- (3). One such technique is known as negative pressure wound therapy (NPWT), which can be used to treat superficial wounds and drain deep wounds. It can completely remove the necrotic tissue and wound secretions, stimulate the production of granulation tissue, lower bacterial infection levels, and accelerate wound healing
- (4). In essence, NPWT is a mechanical system that uses a tube to attach to a suction device to produce a sub-atmospheric pressure between the wound and the outside to clear exudate and quicken healing.
- (5). Despite the fact that NPWT is generally acknowledged to be successful, there are significant variations in clinical literature reports, and there is a dearth of quantitative analysis of study data.

Answer:
Medical direction of the pre-hospital management of the sick and injured.
Explanation:
Emergency Medical Services, more commonly known as EMS, is a system that provides emergency medical care. Once it is activated by an incident that causes serious illness or injury, the focus of EMS is emergency medical care of the patient(s).
