Answer 20

reassessment

Question 21

Most medical emergencies require a level of treatment beyond that available in the prehospital setting.

Question 26

__patients include those with altered mental status, airway or breathing difficulties, or any sign of circulatory compromise. In addition, a patient who is very old or very young may be considered critical even if the patient appears to be relatively stable.__ patients often need expeditious transport. The time on scene should be limited to 10 minutes or less for these patients.

Answer 26

Critical patients

Question 27

Differentiating a high-priority transport from a low-priority transport is a skill developed with experience, but it is a skill that can be learned. A general rule for determining the priority of transport is to consider the results of the patient's primary assessment. Patients with an altered mental status, especially if it is still present at the completion of your assessment and treatment, should be considered a__ transport. Patients with circulatory compromise, including signs and symptoms of shock, should also be considered a___ transport. Most patients with circulatory problems cannot be stabilized in the prehospital setting and need to undergo treatment at a hospital quickly but safely. Patients with difficulty breathing often require high-priority transport. However, if the patient has responded well to your initial treatment, such as oxygen and albuterol administration, lights and siren may not be necessary.

Answer 27

high-priority transport

Question 28

Answer 38

Influenza

Question 39

The__ virus, which was initially identified as the swine flu in 2009, is a specific form of influenza. Other viruses of concern include Middle East respiratory syndrome (MERS), severe acute respiratory syndrome (SARS), COVID-19, which are discussed later. The__ virus has been present for years in animals. Many deaths have been caused by the__ virus, although deaths caused by other influenza viruses have also occurred. The most positive effect of the outbreak of the__ virus has been the general public's greater awareness of the routes of transmission of contagious diseases. This increased awareness could result in a reduction of all communicable diseases, not only___.

Answer 39

H1N1 virus

Question 40

Wear a ___or an___ mask during any aerosol-generating procedures such as suctioning of airway secretions, performing cardiopulmonary resuscitation, or assisting with endotracheal intubation.

Answer 40

Question 41

A common virus that is asymptomatic in 80% if people carrying it, but characterized by small blisters on the lips or genitals in symptomatic infections

Answer 41

Herpes simplex

Question 42

__is a common virus strain carried by humans. Eighty percent of people carrying the virus are asymptomatic, but symptomatic infections cause eruptions of tiny fluid-filled blisters called vesicles that often appear on the lips or genitals. __can cause more serious illnesses like pneumonia and meningitis in very young, very old, and immunocompromised patients. The primary mode of infection is through close personal contact, so standard precautions are generally sufficient to prevent spread to or from health care workers.

Answer 42

Herpes simplex

Question 43

Acquired immunodeficiency syndrome (AIDS) is caused by __, which damages the cells in the body immune system so that the body is unable to fight infection or certain cancers

Answer 43

HIV

Question 44

Fortunately,__ is not easily transmitted in your work setting. For example, it is far less contagious than hepatitis B although immunization for hepatitis B is important.__ infection is a potential hazard only when deposited on mucous membranes or directly into the bloodstream. Transmission can occur via sexual contact or exposure to blood or body fluids, meaning your risk of infection is limited to exposure to an infected patient's blood and body fluids. Exposure can take place in the following ways: • The patient's blood is splashed or sprayed into your eyes, nose, or mouth or into an open sore or cut, however tiny; even a microscopic opening in the skin is an invitation for infection with a virus. • You have blood from the infected patient on your hands and then touch your own eyes, nose, mouth, or an open sore or cut. • A needle used to inject the patient breaks your skin. The risk to you from a single injection, even with a hollow-bore needle, is small, probably less than 1 in 1,000. However, this is by far the most dangerous form of exposure. • Broken glass at a motor vehicle crash or other incident penetrates your glove (and skin), which may have already been covered with blood from an infected patient.

Answer 44

HIV

It is an uncommon but very frightening infectious disease.__ can be caused by viruses or bacteria, most of which are not contagious.

Answer 66

Meningitis

Question 67

__, one form of meningitis, however, is highly contagious.__ is an inflammation of the meningeal coverings of the brain and spinal cord. The bacteria that cause __can be spread by the exchange of respiratory secretions through coughing and sneezing. The effects are lethal in some cases. Victims who survive can be left with brain damage, hearing loss, or learning disabilities. Patients may present with flulike symptoms, but high fever, severe headache, photophobia (light sensitivity), and a stiff neck in adults are symptoms that are highly suggestive of meningitis. Patients sometimes have an altered level of consciousness and can have red blotches on the skin. Use respiratory protection, provide rapid transportation, and provide early notification to the ED so they can make specific preparations for accepting a highly contagious patient.

Answer 67

Question 68

Only laboratory tests can sort out the different forms of meningitis; therefore, you should take__ with any patient who is suspected of having meningitis.

Answer 68

standard precautions

Question 69

A chronic bacterial disease, caused by mycobacterium tuberculosis, that usually affects the lungs but can also affect other organs such as the brain and kidneys; it is spread by cough and can lie dormant in a persons lungs for decades and then reactivate

Answer 69

Tuberculosis

Question 70

Although tuberculosis is often hard to distinguish from other diseases, patients who pose the highest risk almost invariably have a cough. Therefore, for your safety, you should consider respiratory tuberculosis to be the only contagious form because it is the only one that is spread by__. The droplets produced by coughing are not the rea problem. The real problem is the droplet nuclei, which are the remnants of the droplets after the excess water has evaporated. These particles are tiny enough to be invisible and can remain suspended in the air for a long time. In fact, as long as these particles are shielded from ultraviolet light, they can remain alive for decades. Particles that are the size of droplet nuclei are not stopped by routine surgical masks. Inhaled, they are carried directly to the alveoli of the lungs, where the bacteria may begin to grow. N95 or HEPA masks are required to stop droplet nuclei

Answer 70

airborne transmission

Question 71

The spread of an organism via droplets or dust

Answer 71

Airborne transmission

Question 72

If you are exposed to a patient who is found to have pulmonary tuberculosis, you will be given a tuberculin skin test. This simple skin test determines whether a person has been infected with M tuberculosis, A positive result means that exposure has occurred; it does not mean that the person has active tuberculosis. It takes at least 6 weeks for the bacteria to show up in the laboratory test. So if you are tested for the disease within a few weeks of the exposure and your results are positive, this means that you were exposed to tuberculosis at an earlier time from somebody else. You will probably never identify the source. Most transmissions occur silently, so it is necessary that you have tuberculin skin tests regularly. If the infection is found before you become ill, preventive therapy is almost 100% effective. Usually, a daily dose of the medication__ will prevent the development of active infection.

Answer 72

isoniazid

Question 73

Answer 73

Whooping cough

Question 74

Also called whooping cough, An airborne bacterial infection that affects mostly children younger than 6 years. Patients will be feverish and exhibit a "whoop" sound on inspiration after a coughing attack; highly contagious through droplet infection.

Answer 74

Pertussis

Question 75

An infectious disease in which a pseudomembrane forms, lining the pharynx; this lining can severely obstruct the passage of air into the larynx

Answer 75

Diphtheria

Question 76

__is a bacterium that causes infections and is resistant to many antibiotics. In health care settings,___ is believed to be transmitted from patient to patient via unwashed hands of health care providers. Studies have shown that 5% to 15% of health care providers carry___ in their nares. Up to 65% of people presenting with hand infections from the community have_. In addition, children with no health care exposure present with_. The pathogen can subsequently be transferred to skin and other areas of the body through a break in the skin. Surfaces contaminated with__ do not seem to be important in transmission. Factors that increase the risk for developing __ include antibiotic therapy, prolonged hospital stays, a stay in an intensive care or burn unit, and exposure to an infected patient. The incubation period for__ appears to be between 5 and 45 days. The communicable period varies, as patients who have active infection may carry__ for months.__ results in soft-tissue infections. Its signs and symptoms may involve localized skin abscesses, and sepsis may be found in older patients with the infection.

Question 79

The period of time between a person being exposed to an agent and the time when symptoms appear

Answer 79

Incubation

Question 80

In 2014, an outbreak of the__ virus in West Africa caused international concern. Several infected people with the virus traveled to other countries, including the United States, motivating EMS and health care facilities to prepare for further outbreaks. The incubation period is approximately 6 to 12 days after exposure; however, symptoms may not begin to appear for as long as 21 days after infection. Symptoms include watery diarrhea, vomiting, fever, body aches, and bleeding. The fatality rate can be as high as 70% if effective supportive treatment in an intensive care unit is not initiated promptly. If you suspect your patient may have this condition, place a surgical mask on him or her and follow PPE precautions as outlined by local protocols and the CDC. Immediately notify the receiving facility that your patient may have or may have been exposed to the__ virus.
