B. loss of bladder control and sensitivity to touch. D: ask them repeatedly how the child was injured. Prevention of cardiac arrest in infants and small children should focus primarily on: - A: keeping the child warm. The anterior wall is the largest part of the heart and tends to sustain significant damage as the result of an MI. D: manually stabilizing the head, applying a cervical collar, and removing the patient from the vehicle onto a long backboard. B: keeping the cord moist and providing rapid transport.

Paramedics are trained to treat patients with minor injuries on the scene of an accident or at their home without transporting them to a medical facility. C: purple and yellow bruises to the thighs. Pertinent past history: "I have high blood pressure and the doctor told me I may have a heart attack if I don't start. D: 8 to 10 breaths/min. B: provide oxygen and other nutrients to the fetus. The pain associated with cardiac ischemia is usually substernal; however, it may be localized to the epigastrium and is commonly mistaken for indigestion. D: An 18-year-old man who is now fully alert after receiving oral glucose. B: Wearing your seatbelt and shoulder harness |. B: open the airway and ventilate. When assessing a 78-year-old female who complains of shortness of breath, the EMT should: A. give oxygen only if the patient has labored breathing. B: immediately apply high-flow oxygen to the patient and allow extrication to begin. The reduction in brain weight and volume increases an older person's risk for: A. Dementia. This is well addressed, I think, by the following anonymous comment: "You're asking the wrong question. Begin his or her assessment after gathering any medication bottles.
A: how to provide rescue breathing. The difficulties are threefold; -Inability to maintain a mask seal. You note that her heart rate has increased from 90 to 120 beats/min and she is diaphoretic. Level of consciousness: Conscious and alert to person, place and time; less restless. D: immediately perform CPR. His left leg is red, swollen, and painful.

D: is breathing with a significant reduction in tidal volume. Your assessment reveals a large contusion over the left upper quadrant of her abdomen and signs of shock. C: place a rolled towel behind the head. This discussion focused predominantly on three themes: (1) Advantages and ease of the skill, (2) need for capnography for airway confirmation and (3) the need for additional education and training commensurate with the complexity of not just the skill, but its indications and monitoring. C: give the mother high-flow oxygen and transport her on her side.

The technique of rapid extrication from a vehicle involves: - A: grabbing the patient by his or her clothing, protecting his or her spine as much as possible, and dragging him or her from the vehicle.
The molecule must be cyclic. Identifying Aromatic Compounds - Organic Chemistry. Aldol condensations are also commonly discussed in university level organic chemistry classes as a good bond-forming reaction that demonstrates important reaction mechanisms. Question: Draw the product formed when C6H5N2+Cl– reacts with each compound. Which of the compounds below is antiaromatic, assuming they are all planar? In the Guerbet reaction, an aldehyde, formed in situ from an alcohol, self-condenses to the dimerized alcohol.
Differentiation of kinetically and thermodynamically controlled product compositions, and the isomerization of alkylnaphthalenes. Although it's possible that a molecule can try to escape from being antiaromatic by contorting its 3D shape so it is not planar, cyclobutadiene is too small to do this effectively. Example Question #10: Identifying Aromatic Compounds. Draw the aromatic compound formed in the given reaction sequence. x. A Quantitative Treatment of Directive Effects in Aromatic Substitution. Journal of the American Chemical Society 2003, 125 (16), 4836-4849. This is indeed an even number. If you're sharp, you might have already made an intuitive leap: the ortho- para- directing methyl group is an activating group, and the meta- directing nitro group is deactivating.
One clue is to measure the effect that small modifications to the starting material have on the reaction rate. This problem has been solved! The molecule is non-aromatic. Reactions of Aromatic Molecules. Let's combine both steps to show the full mechanism. In the Japp–Maitland condensation water is removed not by an elimination reaction but by a nucleophilic displacement. So let's see if this works. Draw the aromatic compound formed in the given reaction sequence 1. Aromatic substitution. A molecule is aromatic when it adheres to 4 main criteria: 1. When looking at anthracene, we see that the molecule is conjugated, meaning there are alternating single and double bonds. So, therefore, are all activating groups ortho- para- directors and all deactivating groups meta- directors?
This is because all aromatic compounds must follow Huckel's Rule, which is 4n+2. The first step of electrophilic aromatic substitution is attack of the electrophile (E+) by a pi bond of the aromatic ring. Draw the aromatic compound formed in the given reaction sequence. 1 phenylethanone reacts with l d a - Brainly.com. This is the grand-daddy paper on nitration, summarizing a lifetime's worth of work on the subject. Spear, Guisseppe Messina, and Phillip W. Westerman. Having established these facts, we're now ready to go into the general mechanism of this reaction. The way that aromatic compounds are currently defined has nothing to do with how they smell.
Dehydration may be accompanied by decarboxylation when an activated carboxyl group is present. But, as you've no doubt experienced, small changes in structure can up the complexity a notch. There are 14 pi electrons because oxygen must contribute 2 pi electrons to avoid antiaromaticity. Intermediates can be observed and isolated (at least in theory); in contrast, transition states have a lifetime of femtoseconds, and although they may fleetingly be observed in certain cases, they can never be isolated. It depends on the environment. Draw the organic product for each reaction sequence. Remember to include formal charges when appropriate. If more than one major product isomer forms, draw only one. | Homework.Study.com. Last updated: September 25th, 2022 |. Advanced) References and Further Reading. There is an even number of pi electrons.
EAS On Monosubstituted Benzenes: The Distribution Of Ortho, Meta and Para Isomers Is NOT Random. For example, 4(0)+2 gives a two-pi-electron aromatic compound. In the second (fast) step a C-H bond is deprotonated to re-form a C-C pi bond, restoring aromaticity. Draw the aromatic compound formed in the given reaction sequence. Is the correct answer the options given location so so we have option is wrong because here we have PHP add this is the wrong one option visit around this is a wrong wrong one options around because addition of BR in meta position in the last option option d option is most appropriate for this case result answer of the occasion thank you. A Quantum Mechanical Investigation of the Orientation of Substituents in Aromatic Molecules. This means that each of the three other atoms connected to the carbon are organized at a angle in a single plane.
