Meds that affect glucose regulation - (answer)insulin, oral hypoglycemic agents, corticosteroids,
estrogen, ACE inhibitors, β-blockers, potassium-depleting diuretics, bronchodilators, antipsychotics, and
many antibiotics.
Renal disease in diabetes - (answer)Significant loss of albumin in the urine (300 mcg/dL) indicates renal
damage
CRP in diabetes - (answer)Often elevated in diabetes
DKA - (answer)The combination of hyperglycemia, ketosis, and acidosis leads to dehydration, and fluid
resuscitation and insulin therapy are required to correct this state. Other symptoms include abdominal
pain, vomiting, poor skin turgor, tachycardia, and hypotension. Stress or illness is a frequent trigger for
DKA.
Hyperosmolar Hyperglycemic Nonketotic Syndrome - (answer)Hyperosmolar hyperglycemic nonketotic
syndrome (HHNS) is a state characterized by hyperglycemia, hyperosmolarity, and dehydration without
acidosis. Occurs in older adults.
HHNS labs - (answer)Labs:
BG >600-1200
Elevated serum & urine glucose
test Ketones absent
Potassium (K) normal or high
Marked increase serum
test 330-380 osmolality ---this should be 275-295 !!!
Na, Cl, Mg, Po4 wnl
Cushing syndrome cause - (answer)Excess corticosteroid secretion

Cushing syndrome symptoms - (answer)hyperglycemia, elevated blood pressure, hypokalemia, central fat
distribution, dark purple striae, ruddy facial complexion, hirsutism, weight gain, easy bruising, and
muscle weakness.
Triage - (answer)Means "to sort"
Basic premise of triage - (answer)Treating patients with a threat to life faster than other patients
Emergency severity index (ESI) - (answer)5-level triage system that incorporates concepts of illness
severity and resource use (e.g., electrocardiogram [ECG], laboratory tests, radiology studies, IV fluids) to
determine who should be treated first. The ESI includes a triage algorithm that directs you to assign an
ESI level to patients coming into the ED
ESI-1 - (answer)the stage at which a patient has a life-threatening condition and needs immediate
treatment. Should be seen by HCP immediately.
ESI-2 - (answer)The stage at which a patient needs immediate treatment, but is not dying. Should be
seen by HCP within 10 mins.
ESI-3 - (answer)The state at which a patient is not critically ill, but needs several resources, must have
normal vitals. Patient must by seen by HCP within an hour
ESI-1 Examples - (answer)Cardiac arrest, intubated trauma patient, overdose with bradypnea, severe
respiratory distress
ESI-2 Examples - (answer)Chest pain from ischemia, multiple trauma unless responsive
ESI-3 Examples - (answer)Abdominal pain or gynecologic disorders unless in severe distress, hip fracture
in older patient

ESI-4 - (answer)Stable, normal vitals, no organ or life threat. Could be delayed when HCP sees patient.
May need 1 simple diagnostic test or procedure (sutures).
ESI-4 Examples - (answer)Closed extremity trauma, simple laceration, cystitis
ESI-5 - (answer)Stable, normal vitals, no threat to life. HCP could be delayed in seeing patient. Low
resource, exam only, no diagnostic tests.
ESI-5 Examples - (answer)Cold symptoms, minor burn, recheck (e.g., wound), prescription refill
Primary survey - (answer)focuses on airway, breathing, circulation (ABC), disability, exposure, facilitation
of adjuncts and family, and other resuscitation aids. If uncontrolled external hemorrhage is noted, the
usual ABC assessment format may be reprioritized to <C>ABC. The <C> stands for catastrophic
hemorrhage. If present, it must be controlled first.6 Apply direct pressure with a sterile dressing followed
by a pressure dressing to any obvious bleeding sites.
Primary survey purpose - (answer)The primary survey aims to identify life-threatening conditions so that
appropriate interventions can be started. You may identify life-threatening conditions related to ABCs at
any point during the primary survey. When this occurs, start interventions immediately, before moving to
the next step of the survey.
AVPU - (answer)A = alert, V = responsive to voice, P = responsive to pain, and U = unresponsive.
jaw-thrust maneuver - (answer)Technique to open the airway by placing the fingers behind the angle of
the jaw and bringing the jaw forward; used for patients who may have a cervical spine injury.
What should you do before intubation or cricothyroidotomy? - (answer)Ventilate patients with 100% O2
using a bag-valve-mask (BVM) device before intubation or cricothyroidotomy
