What are the 2 GENERAL CATEGORIES of illegal psychoactive drugs that<br> exist?

madreJ [45]

Answer:

There are actually 7 categories..

(1) Central Nervous System (CNS) Depressants

CNS depressants slow down the operations of the brain and the body. Examples of CNS depressants include alcohol, barbiturates, anti-anxiety tranquilizers (e.g., Valium, Librium, Xanax, Prozac, and Thorazine), GHB (gamma hydroxybutyrate), Rohypnol, and many other anti-depressants (e.g., Zoloft, Paxil).

(2) CNS Stimulants

CNS stimulants accelerate the heart rate and elevate the blood pressure and "speed-up," or over-stimulate, the body. Examples of CNS stimulants include cocaine, "crack" cocaine, amphetamines, and methamphetamine ("crank").

(3) Hallucinogens

Hallucinogens cause the user to perceive things differently than they actually are. Examples include LSD, peyote, psilocybin and MDMA (Ecstasy).

(4) Dissociative Anesthetics

Dissociative anesthetics include drugs that inhibit pain by cutting off or dissociating the brain's perception of the pain. PCP, its analogs, and dextromethoraphan are examples of dissociative anesthetics.

(5) Narcotic Analgesics

Narcotic analgesics relieve pain, induce euphoria, and create mood changes in the user. Examples of narcotic analgesics include opium, codeine, heroin, demerol, darvon, morphine, methadone, Vicodin, and oxycontin.

(6) Inhalants

Inhalants include a wide variety of breathable substances that produce mind-altering results and effects. Examples of inhalants include Toluene, plastic cement, paint, gasoline, paint thinners, hair sprays, and various anesthetic gases.

(7) Cannabis

Cannabis is the scientific name for marijuana. The active ingredient in cannabis is delta-9 tetrahydrocannabinol, or THC. This category includes cannabinoids and synthetics like Dronabinol.

Answer: The next most appropriate step would be a LUMBAR PUNCTURE.

Explanation:

A LUMBAR PUNCTURE is a medical procedure that is usually carried out by a trained health personnel. It is a procedure that is carried out in the lumbar region of the spinal cord to access and obtain the cerebrospinal fluid which is used for further diagnosis of an underlying disease or illness.

A LUMBAR PUNCTURE is often adviced when the symptoms of a disease is related to the central nervous system. From the symptoms observed from the 19-year-old woman at the emergency department which includes:

--> generalized headache which is increasing in intensity,

--> blurred vision,

--> intermittent diplopia,

--> vague dizziness.

--> bilateral papilledema and

--> normal MRI of the brain.

Since the MRI of the brain is normal, the most appropriate step to be taken by the health care provider is a lumbar puncture which enables a direct access to the cerebrospinal fluid. This would help to rule out an elevated intracranial pressure which may be the cause of the generalized headache which is increasing in intensity.

What symptoms may appear in a newborn if its ductus arteriosus fails to close?

zepelin [54]

Answer:

Poor eating, which leads to poor growth.

Sweating with crying or eating.

Persistent fast breathing or breathlessness.

Easy tiring.

Rapid heart rate.

Explanation:

While still in the mother's womb, a baby does not need their lungs to supply oxygen because they receive oxygen from their mother. Since a baby's lungs do not provide oxygen, there is no need for the heart to pump blood to the lungs. The ductus arteriosus is a blood vessel that is present in all babies while still in the womb, and it allows blood to bypass the lungs.

When the baby is born and the umbilical cord is cut, their lungs need to supply oxygen to their body. Their lungs expand, their blood vessels relax to accept more blood flow, and the ductus arteriosus usually closes within the first hours of life. Sometimes, the ductus arteriosus does not close on its own. This is known as a patent ("open") ductus arteriosus. While this condition is seen more often in premature babies, it may also appear in full-term infants.

The symptoms of a patent ductus arteriosus depend on the size of the ductus and how much blood flow it carries. After birth, if a ductus arteriosus is present, blood will flow from the aorta (the main artery in the body) into the pulmonary artery. This extra blood flow into the lungs can overload the lungs and put more burden on the heart to pump this extra blood. Some babies may need more support from a ventilator and have symptoms of congestive heart failure.

A newborn with a patent ductus arteriosus may have:

Fast breathing

A hard time breathing

More respiratory infections

Tire more easily

Poor growth

However, if the patent ductus arteriosus is not large, it may cause no symptoms and your doctor may not find it until they do further evaluation of a heart murmur.

Even if there are no symptoms, the turbulent flow of blood through the patent ductus arteriosus puts a person at a higher risk for a serious infection, known as endocarditis
