What happens to carbon dioxide levels when a patient breathes faster or slower?
Faster breathing (faster respiration) will result in more CO2 being expelled from the
body. Slower breathing (hypoventilation) causes CO2 levels in the blood to rise due to
the fact that the body is not expelling CO2 at an effective rate.
What are the side effects and complications of narcotic medications?
They cause drowsiness, altered mental consciousness, and pinpoint pupils. Other
symptoms include nausea, vomiting, hypotension, cyanosis, and seizures. The use of
narcotic medications can have critical effects as well such as depression of the
respiratory system, as well as depression of the nervous system, and lastly the
possibility of losing the ability to breathe.

How do you manage an airway with a toxic ingestion?
, You must suction the tablet or pill fragments from the patient's mouth and wash, or
brush dry the poison from the patient's skin. Treatment focuses on support, assess &
maintain the patient's XABCs. Provide oxygen & assist ventilations, if necessary, &
transport promptly. Keep patients warm, treat for shock & give activated charcoal if
needed.

Why do we use epinephrine in anaphylaxis?
Epinephrine is a sympathomimetic hormone, which means it mimics the sympathetic
response. Epinephrine has various properties that cause blood vessels to constrict,
which reverses vasodilation and hypotension; in turn elevates the diastolic pressure and
improves coronary blood flow. Other properties of epinephrine increase cardiac
contractility and relieve bronchospasms in the lungs. Because epinephrine has
immediate action, it can rapidly reverse the effects of anaphylaxis.
Epinephrine is an Alpha 1, Beta 1, Beta 2 Agonist meaning it reverses the effects that
are occurring during anaphylactic shock.
What is glycolysis? (GLYCO - sugar, LYSIS - breaking down)
The breakdown of glucose by enzymes, releasing energy and pyruvic acid, the
breakdown of sugar. In type 1 diabetes, no insulin is produced which is called Diabetic
Ketoacidosis (DKA). In type 2 diabetes there are typically fewer insulin receptors which
is called hyperosmolar hyperglycemic nonketotic syndrome (HHNS).
Why do we give oral glucose and what are the side effects?
Oral glucose is given in order to counteract the effects of hypoglycemia, or ultimately
increase blood sugar levels. Glucose is needed as a fuel for our cells, if levels of
glucose get too low, a person can experience a loss of consciousness, have seizures,
and ultimately die.
