Questions & Answers {Grade A}
Which Drug May Be Safely Administered To A Patient On Phenelzine?
A. Meperidine
B. Cocaine
C. Morphine
D. Ephedrine - correct answer C. Morphine
Explanation:
- In The Synaptic Cleft Monoamine Oxidase (MAO) Metabolizes Serotonin To NE.
Phenelzine INHIBITS MAO, Which INC. Concentration of Serotonin (5-HT) & NE To
Relieve Symptoms Of Depression.
- Common Side Effect Of MAO Inhibitors: Orthostatic Hypotension. .
- Morphine: Safe To Administer To Patients On MAOIs But The Effects Of Morphine Are
Enhanced.
,Why Other Answer Choices Are Wrong:
- Any Drugs That INC. The Concentration Of 5-HT & NE In The Brain Should NOT Be Co-
Administered With MAOIs
- Ephedrine & Cocaine: INC. NE Which Can Lead To HTN Crisis.
- Meperidine: Inhibits Serotonin Reuptake & Can Precipitate Serotonin Syndrome
(Begins As Hyperpyrexia, Skeletal Muscle Rigidity, Headache, & Agitation And Can
Progress To Respiratory Depression, Hypotension & Coma)
Match Each Orbital Muscle With Its Effect On Eye Movement.
Eye Muscles: Lateral Rectus, Medial Rectus, Superior Rectus & Inferior Rectus.
Eye Movement: Supraduction, Infraduction, Adduction & Abduction - correct answer
Lateral Rectus = Abduction
Medial Rectus = Adduction
Superior Rectus = Surpraduction
Inferior Rectus = Infraction
Explanation:
,- 6 Orbital Muscles Innervated By 3 Cranial Nerves: SO 4, LR 6 & All Others 3
- Superior Rectus: Supraduction (CN 3)
- Inferior Rectus: Infraduction (CN 3)
- Medial Rectus: Adduction (CN 3)
- Lateral Rectus: Abduction (CN 6)
- Superior Oblique: Intorsion + Depression (CN 4)
- Inferior Oblique: Extorsion + Elevation (CN 3)
Complications Of Celiac Plexus Blockade Include All Of The Following EXCEPT:
A. Bowel Puncture
B. Constipation
C. Paralysis
D. Hypotension - correct answer B. Constipation
Explanation:
- Celiac Plexus: Contains Afferent & Efferent Fibers From T5 - T12. (Does NOT Contain
Somatic Fibers)
, - Celiac Plexus Blockade: Performed At L1 Just Anterior To L1 Vertebral Body. This
Approach Blocks Nearly All Of The Abdominal Organs & Provides Autonomic Blockade
That Blocks Neuroendocrine Response To Surgical Stress. Often Utilized To Provide
Pain Relief For Cancer Of Upper Abdominal Organs Or May Be Used To Supplement An
Anesthetic For Abdominal Surgery Where Neuraxial Anesthetics Are Contraindicated.
- INC. Peristalsis Occurs With INC. PNS Tone + DEC. SNS Tone To The Gut - May Cause
Diarrhea For The 1st 12 Hours Following The Block.
Why Other Answer Choices Are Wrong:
- Most Common Side Effect: Hypotension ( Preload With 1L Crystalloid To Minimize This
Effect)
- Subarachnoid Or Epidural Injection May Occur & If Neurolytic Agent Is Used This Can
Lead To Paralysis.
- Needle May Pierce Bowel, Kidneys & Ureters (Bowel Puncture)
- Diaphragmatic Irritation is Common (Manifests As Shoulder Pain)
- Needle May Inadvertently Puncture Aorta Or Vena Cava Leading To Retroperitoneal
Hemorrhage.
