Q

When the level of a corticoid steroid is low what gets released from the hypothalamus

A

Corticotropin releasing hormone which then travels to the anterior pituitary gland, it triggers the release of ACTH

25
methylprednisolone administered usually by
IV
26
methylprednisolone available in
long acting formulation
27
what is the preservative contained in most injectable formulations that cannot be given to children of 28 days or younger
benzyl alcohol
28
methylprednisolone dose, onset, peak, half life, duration of action
10-40mg q4h, immediate, 30min, 3-4hr,24-36hr
29
dexamethasone is a synthetic corticosteroid available in
systemic and ophthalmic formulations
30
dexamethasone is used to treat
inflammation, allergic conditions, burns
31
dexamethasone can be used on
eye, eyelids, conjunctiva and cornea
32
dexamethasone route, onset of action, peak, duration of action
ocular, variable, immediate, long
33
an abrupt withdrawal of adrenal drugs can cause
decrease in or no production of endogenous glucocorticoids which results in adrenal insufficiency
34
why would an H2 receptor or PPI order be given with glucocorticoids
minimize GI upset and minimize ulcer formation ( these drugs are ulcerogenic)
35
in long term therapy for glucocorticoids, what is preferred
alternate dosing to help with minimizing adrenal suppresion
36
analgesics are given for
relieve pain without causing loss of consciousness, painkillers, opioid analgesics, adjuvant analgesic drugs
37
adjuvant analgesic drugs are
not primarily designed to control pain
38
pain is
unpleasant sensory and emotional experience associated with actual or potential tissue damage
39
WHO 1st step analgesic ladder is
nonopioid (with or without adjuvant medication) after the pain has been identified or assessed, if pain continues step 2
40
WHO 2nd step analgesic ladder
opiods with or without nonopioid and with or without adjuvants. if pain continues step 3
41
WHO 3rd step analgesic ladder
opiods indicated for moderate to severe pain, administered with or without nonopioid or adjuvant medications
42
example of nonopioid analgesics
tylenol
43
tylenol is similar to
aspirin which is a salicylates
44
mechanism of action for tylenol
blocks pain impulses peripherally by inhibiting prostaglandin synthesis
45
tylenol uses
analgesic and antipyretic effects
46
indications for tylenol
mild to moderate pain, fever and alternative for those who cannot take aspirin
47
contraindications for tylenol
liver dysfunction, possible liver failure
48
taking tylenol is dangerous if taken with
other drugs that are hepatotoxic
49
prostaglandin synthesis is
cellular damage cause by thermal, mechanical or chemical stimuli which results in release of excitatory neurotransmitters ( prostaglandins, bradykinin, substance P and histamine)
50
max dosage for a healthy adult
3000mg/day, 2000mg for older adults and those with liver disease
51
ovedose of tylenol cause
hepatic necrosis, hepatotoxicity( liver damdge)
52
antidote for overdose of tylenol
acetylcysteine regimen ( used to prevent liver damage)
53
NSAIDS MOA
inhibitions of the leukotriene pathway ( one of the groups that cause inflammation) - the prostaglandin pathway (inflammation)
54
aspirin(salicylate) uses are
inhibits platelet aggregation and antithrombotic effect ( treatment of MI and other thromboembolic disorders)
55
salicylate (aspirin) used for
headache, neuralgia ( nerve pain) myalgia ( muscle pain) and arthralgia ( joint paint)
56
side effects for salicylate ( aspirin)
increased heart rate, hypoglycemia, hyperglycemia, nausea, vomiting, diarrhea
57
Reyes syndrome is
acute and potential life threatening condition of neurological deficits that can lead to coma and liver damage.
58
opiod drugs used for
pain relieving drugs known as opioid analgesics
59
morphine and codeine are from
opium poppy
60
opioid drugs are
resynthetic drugs that bind to opiate receptors for pain
61
strong agonists are
morphine, hydromorphone(dilaudid) oxycodone, oxymorphone
