Begin in a different place on the court so your opponent serves there
Begin moving in anticipation of where the ball will land
Stay in ready position and move only when the ball lands
Stay in ready position and wait to see if it bounces off a side wall

HPI Mrs. Roxana Collach presented to the ED with a 2-day history of increasing epigastric pain. She described the pain as constant and dull with radiation to her back. She also had progressive anorexia. She denied nausea, emesis, or diarrhea. She was febrile in the ED and had marked epigastric tenderness on exam with guarding. Her abdomen was slightly distended, and she was mildly jaundiced. Her elevated amylase and lipase confirmed the suspicion of acute pancreatitis. She was admitted for pain control and IVF.

B. The lab results confirmed the patient has an inflamed pancreas.
C. The patient experienced pain in the upper center portion of the abdomen.

The not true statement, given the health record information of Mrs. Roxana Collach is:
E. Upon examination the patient revealed tenderness in the lower center portion of the abdomen.
Explanation:
Mrs Collach, according to the health records, experienced epigastric tenderness, which can typically cause some discomfort below her ribs in the area of her upper abdomen and not "in the lower center portion of the abdomen." Icterus comes with slight yellowing of the skin, which is usually a symptom of other infections.

(have this done correctly for brainliest)
Answers
Answer:
Hallucinogens are a diverse group of drugs that alter a person’s awareness of their surroundings as well as their own thoughts and feelings. They are commonly split into two categories: classic hallucinogens (such as LSD) and dissociative drugs (such as PCP). Both types of hallucinogens can cause hallucinations, or sensations and images that seem real though they are not. Additionally, dissociative drugs can cause users to feel out of control or disconnected from their body and environment.
Some hallucinogens are extracted from plants or mushrooms, and some are synthetic (human-made). Historically, people have used hallucinogens for religious or healing rituals. More recently, people report using these drugs for social or recreational purposes, including to have fun, deal with stress, have spiritual experiences, or just to feel different

5. List 5 types of stimulants and the impact they have on the body.
Answers
Answer:
Stimulant drugs are the treatment most often used for ADHD. They can help you manage symptoms, such as Short attention span Impulsive behavior Hyperactivity
Depressant drugs slow down the functioning of the brain. They typically relieve anxiety. They don’t necessarily make a person feel depressed, but rather reduce co-ordination and impair concentration and judgement.
Hallucinogenic drugs distort perceptions of reality, i.e. they change the way a person sees, hears and feels about a situation. For example, a person may see things that do not actually exist, or a normal sensory experience may be exaggerated (such as seeing colours more vividly).
Many stimulants can also be addicting. Stimulants share many commonalities, but each has unique properties and mechanisms of action. Drugs that are classified as stimulants include:
Caffeine
Cocaine
Methamphetamine
Nicotine
Prescription stimulants
Caffeine is the most widely used psychoactive drug in the world, found in coffee, tea, cocoa, chocolate candy, and soft drinks.1 While caffeine has several positive effects such as increasing energy and mental alertness, heavy use can cause symptoms such as anxiety and insomnia.Caffeine is physically addictive, and withdrawal symptoms can include headaches, fatigue, and irritability
Nicotine is considered one of the three most widely used psychoactive drugs in the world despite the fact that there are few (if any) medical uses for the drug.Nicotine is a primary ingredient in e-cigarettes, and vaping is highly addictive.
Cocaine is an illegal psychoactive drug made from the leaves of the coca tree.Cocaine is rapidly absorbed from any administration point, including being snorted, inhaled, injected or taken orally. The drug reaches the brain quickly and is then distributed to other tissues throughout the body. Cocaine is rapidly metabolized by enzymes in the liver and plasma in approximately 30 to 60 minutes but can be detected in urine tests for up to 12 hours after administration.
Explanation: There is no safe level of alcohol or drug use and the use of any drug always carries some risk. Combining drugs also known as ‘poly drug use’ increases the risk and can be extremely dangerous. The effects of mixing drugs can be unpredictable and people are more at risk of overdose, including death.

Explanation:
To create a buffer that maintains a pH of around 7.54, solution a. [tex]CH3COOH[/tex]and [tex]NaCH3COO[/tex] would be chosen.
A buffer solution is made up of a weak acid and its conjugate base, or a weak base and its conjugate acid. The pH of a buffer solution is maintained by the equilibrium between the weak acid and its conjugate base, or the weak base and its conjugate acid. The pKa or pKb value of the components of the buffer solution determines the pH at which the buffer is most effective.
Out of the given options, solution a.[tex]CH3COOH[/tex] and [tex]NaCH3COO[/tex]contains a weak acid, acetic acid [tex](CH3COOH)[/tex], and its conjugate base, sodium acetate[tex](NaCH 3COO)[/tex]. The pKa value of acetic acid is 4.76, which is significantly lower than the desired pH of 7.54. However, by choosing the ratio of acetic acid and sodium acetate, a buffer solution can be created that maintains a pH of 7.54.
To create a buffer solution with a pH of 7.54, the concentration of the conjugate base, sodium acetate [tex](NaCH 3COO)[/tex], must be higher than that of the weak acid, acetic acid [tex](CH3COOH).[/tex] This will result in a buffer solution with a pH close to the pKa of acetic acid. The buffer capacity of the solution will be maximum at this pH, and any addition of strong acid or base will be neutralized by the weak acid and its conjugate base, maintaining the pH of the buffer solution around 7.54. Therefore, solution a. [tex]CH3COOH[/tex]and [tex]NaCH3COO[/tex] would be chosen to create a buffer solution that maintains a pH of around 7.54.
