Answer:
The blood pressure is directly proportional to the total length of the vessel.
Explanation:
The blood pressure is directly proportional to the total length of the vessel.
The long blood vessel will have higher the resistance and the flow of blood will be lower.
Thus, making intuitive sense, as with blood volume, as the vessel's enhanced surface area will impede blood flow. This lowering area will lead to the higher blood pressure through the blood vessel. Similarly with the reduction in the resistance of the blood vessel, the blood flow will boost.

Explanation:
Headache is the most common symptom. Most symptoms resolve within 14 to 21 days. Although recovery plans are unique to each person, all involve mental and physical rest and a gradual return to activity
Answer:
The onset, and treatment of PTSD is no easy matter. In order for such a disorder to appear, which is later expressed with tremendous peaks of stress, crisis, behavioral problems, panic disorders, anxiety disorders, and many more debilitating conditions, a person must have experienced an event, or circumstance, that traumatically negatively impacted the correct psychological and emotional processes of the mind. In these patients, one the most common situations is that panic attacks and anxiety peaks happen particularly when the traumatic event, moment, or circumstance is remembered, and they are very good at remembering not just the moment itself, but all elements that surrounded that trauma. Also, they are able to make really clear connections and associations between those events and normal events in life that, when they appear, trigger the defensive responses of the mind.
The idea of administering a patient with PTSD with medication that would stop memory formation shortly after a traumatic event would not be a good idea simply because while the drugs focus on the chemical processes involved in memory formation, this procedure ignores that memory is much more than just chemicals in the brain. This has been show time and time again in research. Even with strong medication that basically generates amnesia, or trauma to the brain that may cause amnesia, it has been seen, and science cannot yet fully explain how, these patients may have partial, or total recovery of memories. And because the process of memory formation is still so misunderstood, and not all the factors involved are completely known, simply administering a drug that would stop the hormones that are believed to play a role in memory formation could become more of a problem for the patient. Also it is not being considered that amnesia causes even more stress in patients, as somehow the brain still recognizes that there is information present, but cannot simply bring it to concious awareness.
The nurse will perform pulse oximetry to monitor the effectiveness of the oxygen therapy ordered for the client.
<h3>What is pulse oximetry?</h3>
The oxygen saturation level of your blood can be measured with a non-invasive procedure called pulse oximetry.
It can quickly identify even minute variations in oxygen levels. These levels demonstrate how well blood transports oxygen to your arms and legs, which are the extremities that are farthest from your heart. It looks like a little clip and is called a pulse oximeter. It fastens to a body component, usually a finger.
Pulse oximetry is helpful for postoperative patients, monitoring individuals at risk for hypoxia, titrating oxygen therapy, and monitoring patients receiving oxygen therapy.

Answer:
10 per 1,000.
Explanation:
The death rate and birth rate affects the population dynamics of the particular area. The birth rate increases the population size whereas the death rate decreases the population size.
The death rate of a population can be calculated by the following formula:
Crude death rate = total death/ total population
Here, total death = 1,000 and total population = 100,000.
Crude death rate = 1,000/ 100,000 = 0.01 or 10 per 1,000.
Thus, the correct answer is option (c).
