PN 2005 Drugs Exam Questions With
Correct Answers
Midazolam - CORRECT ANSWER✔✔-May potentiate the effects of
| | | | | | | |
GABA, depress the central nervous system, and suppress the spread of
| | | | | | | | | | |
seizure activity. |
Morphine - CORRECT ANSWER✔✔-Uknown. Binds with opioid
| | | | | | |
receptors in the central feverous system, altering perceptions of and
| | | | | | | | | |
emotional response to pain. | | |
Naloxone - CORRECT ANSWER✔✔-May displace opioid analgesics from
| | | | | | | |
their receptors (competitive antagonism); drug has no pharmacologic
| | | | | | | |
activity of its own.
| | |
Nitrofurantoin - CORRECT ANSWER✔✔-May interfere with bacterial | | | | | | |
enzymes systems and bacterial cell-wall formation.
| | | | |
Nitroglycerin - CORRECT ANSWER✔✔-Reduces cardiac oxygen demand
| | | | | | |
by decreasing left ventricular end-diastolic pressure (preload) and, to a
| | | | | | | | | |
lesser extent, systemic vascular resistance (afterload). Also increases
| | | | | | | |
blood flow through the collateral coronary vessels.
| | | | | |
, Nystatin - CORRECT ANSWER✔✔-Probably binds to sterols in fungal cell
| | | | | | | | | |
membrane, altering cell permeability and allowing leakage of
| | | | | | | |
intercellular components. |
Omeprazole - CORRECT ANSWER✔✔-Inhibits proton pump activity by
| | | | | | | |
binding to hydrogen-potassium adenosine triphosphatase, located at
| | | | | | |
secretory surface of gastric parietal cells, to suppress gastric acid
| | | | | | | | | |
secretion.
Oxytocin - CORRECT ANSWER✔✔-Cause potent and selective
| | | | | | |
stimulation of uterine and mammary gland smooth muscles.
| | | | | | |
Dilantin - Phenytoin - CORRECT ANSWER✔✔-May stabilize neuronal
| | | | | | | |
membranes and limit seizure activity either by increasing efflux or
| | | | | | | | | |
decreasing influx of sodium ions across cell membranes in the motor
| | | | | | | | | | |
cortex during generation of nerve impulses.
| | | | |
Phenobarbital - CORRECT ANSWER✔✔-Increases the amount of time
| | | | | | | |
chloride channels are open which in turn depresses the central nervous
| | | | | | | | | | |
system. Done by acting on GABA-A receptor subunits.
| | | | | | |
Potassium Acetate/Chloride - CORRECT ANSWER✔✔-Replaces
| | | | |
potassium and maintains potassium levels
| | | |
