Question 1

epinephrine (or adrenaline) effects on the body:

Answer 1

https://allergyasthmanetwork.org/anaphylaxis/what-is-epinephrine/

Makes the heart to pump faster and harder. This raises your blood pressure and circulates blood more quickly throughout the body

dilates the airways and may reduce swelling

pupils in your eyes to dilate

skin goes pale as bl is diverted to major organs

increased bl flow to muscles

may cause anxiety

begins to work immediately but full effect may take 5-10 mins. begins to wear off in 20-30 mins so its possible a second dose would be needed (with medical control approval)

Question 2

Anaphylaxis is diagnosed when symptoms appear on two or more body organ systems. Anaphylaxis symptoms involve:

Answer 2

skin: itching, redness, swelling, hives that are widespread

shortness of breath, wheezing, coughing, chest pain and/or tightness

Heart: weak pulse, dizziness, faintness

Headache, nasal congestion, watery eyes, sweating

confusion

loss of consciousness

Question 3

O2 delivery, percentage given per L/min

Answer 3

xygen delivery devices such as a nasal cannula, venturi mask, and high-flow nasal cannula can deliver varying FiO2. A patient breathing ambient air is inhaling a FiO2 of 21%. Oxygen delivery devices determine the flow rate and FiO2 based on predicted equipment algorithms. The conventional prediction model states that for every liter of oxygen supplied, the FiO2 increases by 4%. Therefore, a nasal cannula set at a 1 L/min flow rate can increase FiO2 to 24%, 2 L/min to 28%, 3 L/min to 32%, 4 L/min to 36%, 5 L/min to 40%, and 6 L/min to 44%.

so, 6 L/min of a nasal cannula would provide 44% (while ambient air is at 21%).

Question 4

aspirin overdose symptoms:

Answer 4

rapid HR

rapid breathing (*deep and rapid)

agitation

fever

confusion, collapse, coma

nausea, vomiting

bleeding (too much aspirin intake can cause GI bl over time)

hallucinations

drowsiness

Question 5

Which of the following sets of vital signs would the EMT MOST likely encounter in a patient with acute cocaine overdose?

Answer 5

BP, 200/100 mmHg; pulse, 150 bpm.

Question 6

11. Nitroglycerin, when given to patients with cardiac-related chest pain:

Answer 6

relaxes the walls of the coronary arteries

Question 7

albuterol is generic name for

Answer 7

ventolin

Question 8

a ptnt is U after overdosing on aspirin, most likely resps will be:

rapid and shallow (incorrect)

deep , rapid

slow, deep

slow, shallow

Answer 8

deep, rapid

Question 9

pulse oximetry :

incorrect: caution must be exercised when using on ptn with carbon mono poisoning

Question 10

unlike an automatic implantable cardiac defib (AICD) , the external defib vest:

does not warn when a shock is about to be delivered (incorrect)

delivers high-energy shocks, similar to an AED

Answer 10

delivers high-energy shocks, similar to an AED

Question 11

LFT ventricle has the thickest walls because it

pumps bl into the aorta

pumps bl to the lungs to be reo2’ed (incorrect)

Answer 11

pumps bl into the aorta

Question 12

ventricular tachycardia causes hypotension because:

Answer 12

LFT venticle does not adequately fill w/blood

Question 13

ptnt with angina/chest pain, you should assume AMI because:

angina and AMI present identically (incorrect)

Question 14

flowmeter set at 6 Lpm the nasal cann will deliver how much o2?

Answer 14

44%

(ambient air is at 21%, for every addtnl liter, add +4 gets u in the range)

Question 15

Which of the following physiologic actions does epinephrine produce when given for an allergic reaction?

Answer 15

Bronchodilation and vasodilation.

Question 16

overdose of ___ can cause ringing in ears

Answer 16

aspirin
