Answer:

High concentrations of vasoconstrictor substances will increase the peripheral resistance.

Explanation:

Vasoconstriction substances cause blood vessels to narrow their lumen. The more narrow lumens, harder it is for the blood to go through that vessel. The reason for this is because the resistance increased, meaning that the friction between the blood and the vessels' walls is higher.

When we talk about peripheral resistance, it means the sum of all individual resistance of the body blood vessels (all arteries, all capillaries, all veins).

What are some of the effects of not having a claim scrubbed prior to submission ?

LUCKY_DIMON [66]

· Claim rejections are often the result of human error, and can easily be avoided. Manually checking claims before they're submitted to the insurance payer can be a time-consuming process, and claims re-work due to rejections can be costly. The AMA has identified these as the most common medical coding errors.

A five-year-old presents to the emergency department with epiglottitis

the nurse's first priority should be control of anxiety,facilitation of learning, Medications, and Hydration.

<h3>Epiglottis</h3>

The throat's epiglottis, a leaf-shaped flap, serves to keep food and liquids out of the windpipe and the lungs. When breathing, it remains open, allowing air to enter the larynx. It closes during swallowing to stop food from being inhaled into the lungs, forcing any liquids or food to travel down the esophagus and toward the stomach.

<h3>Interventions in Nursing</h3>

For a child with epiglottitis, the nursing interventions are:

control of anxiety:- The family should demonstrate personal activities that will help the youngster get rid of or lessen emotions of anxiety and stress that are coming from an unknown source.
facilitation of learning:- In addition to encouraging progress in the patient's capacity and openness to accept information, the nurse should support their ability to process and comprehend information.
Medications:- As directed, give antibiotics such as cefuroxime.
Hydration:- Since the child couldn't swallow, adjust the IV fluid as necessary.

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).

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.
