QUESTIONS AND CORRECT ANSWER LATEST 2025-2026
Opioid agonist: binds to the opioid mu-1 and mu-2 and
kappa receptors in the CNS and alters pain
• Morphine
perception and response
Side effects: confusion, sedation, constipation,
hypotension, respiratory depression Antidote=
naloxene
Opioid agonist mu-1 and mu-2 and
kappa receptors. side effects:
-Nausea
- Vomiting
- Euphoria
• Demerol
- Dysphoria
- Respiratory
Depression
Adverse effect:
seizures
Antidote=
naloxene
Potentiates action of GABA, resulting in increased
neuronal inhibition and CNS depression,
• Ativan
Side effects:
•
CNS: dizziness, drowsiness, lethargy, hangover,
headache, ataxia, slurred speech, forgetfulness,
confusion, mental depression,

1. Anticonvulsant: stabilizes neuronal membranes and
limits seizure activity by either increasing efflux or
decreasing influx of sodium ions across cell
membranes in the motor cortex during generation of
nerve impulses.
2. Antiarrhythmic: normalizes sodium influx to
Dilantin
Purkinje's fibers in patients with induced
dysrhythmias.
Side effects:
1. nausea, vomiting
2. CNS depression
3. respiratory depression
4. heart blocks
5. hypotension
6. dysrhythmias
-Reduces venous tone. (Blood pooling in periph veins,
decreasing venous return to the heart.
-Decreased periph. vascular resistance.
-Dilation of coronary arteries and relief of coronary artery spasm.
-Vasodilation of cerebral arteries, increasing O2 to brain.
-Generalized smooth
muscle relaxation. Side
effects:
• Nitroglycerine
Dizziness, hypotension, headache, -nausea
-vomiting
-blurred vision
-dizziness
-syncope
-diaphoresis
-confusion
-dry mouth
-palpations
interferes with vitamin K synthesis
that produces clotting. it takes 72
• Coumadin
hours to become active in system
give with heparin until PT/INR gets
to 2 and above Side affects=
bleeding, cramps, nausea
