Adrenergic agonist
The adrenergic agonist epinephrine treats which condition?
A. Opioid overdose
B. Anaphylactic shock
C. Hypertensive crisis
D. EPS
B. Anaphylactic shock
Epinephrine causes beta 1/2 and alpha 1/2 stimulation resulting in increased heart rate, BP and dilated bronchioles
Atropine is used for which indication?
A. Pupil constriction
B. Increasing salivation
C. Drying secretions
D. Decreasing heart rate
C. Drying secretions, by blocking parasympathetic, there is a reduction in oral and gastric mucosal secretions beneficial before surgery or respiratory distress.
Bethanachol chloride is commonly used for bladder retention, how does this medication work?
A. Increases diuresis by wasting Na
B. Relaxes bladder muscle to hold more urine
C. Reduces GFR and urine output
D. Stimulates smooth muscle contraction of the bladder
D. Stimulates smooth muscle contraction of the bladder
Blocking beta 1 receptors results in decreased heart rate, what does blocking Beta 2 receptors result in?
A. Pupil dilation
B. Bronchodilation
C. Bronchoconstriction
D. Increased heart rate
C. Bronchoconstriction occurs when the sympathetic nervous system is blocked, parasympathetic dominates.
Epinepherine will increase all of the following except:
A. Heart rate
B. Glucose
C. Urine output
D. Pupil size
C. Urine output. Stimulating the SNS causes urine retention and relaxation of the bladder, constriction of sphincter and prostate.
Benztropine improves muscle coordination how? (SATA)
A. Increases Ach at neuromuscular junction
B. Increases dopamine at neuromuscular junction
C. Decreases Ach at neuromuscular junction
D. Blocks dopamine in the periphery
B and C
Atenolol is more selective for B1 receptors and has a decreased risk of bronchoconstriction.
A. True
B. False
A. True
Patient's using an Epi pen should be educated to inject where?
A. Gluteus
B. Deltoid
C. Vastus lateralis
D. Abdomen
C. Vastus lateralis, or the outer thigh, can pierce through clothing, massage site afterward.
Tolterodine tartrate is selective to treat which condition?
A. Urinary calculi
B. Urinary frequency
C. Urinary infection
D. Urinary retention
B. Urinary frequency is reduced because the bladder is relaxed and able to fill with more volume, sphincter constricts to hold more urine.
Beta blockers must be held for which physiologic parameters?
A. HR 65 BP 110/68
B. HR 55 BP 90/60
C. HR 110 BP 115/82
D. HR 90 BP 145/86
B. Bradycardia and hypotension
