Q

metabolism

A

Depends on enzyme systems-
concurrent use of other drugs, environmental
pollutants, disease processes, and age affect
this process.

Q

A patient with poor kidney function will have what?

A

an

increased action and duration of a drug.

23
Q

what is the half life of digoxin?

24
Q

Onset of action

A

When the concentration of a drug at
the site of action is sufficient to start a physiologic
response

25
Peak action
Time at which the drug reaches the | highest concentrations on the target receptor sites
26
Duration of action
How long the drug has a | pharmacologic effect
27
DRUG BLOOD LEVEL
When a drug is circulating in the blood
28
when would a drug blood level be important?
anticonvulsants
29
If drug blood level is low
dosage may be increased
30
if a drug blood level is high
dosage must be reduced
31
DRUG INTERACTIONS
When the action of one drug is altered or changed | by the action of another drug
32
Desired Action
What we want to happen
33
Side effects
Things we know can happen but hope they don’t.
34
Adverse effects
Things that happen that were unexpected or dangerous. | common and serious
35
Idiosyncratic reactions
Occur when something unusual/abnormal | happens when drug is first administered
36
Allergic reactions
the abnormal reaction of your immune system to a | medication
37
Most drug interactions that alter absorption happen in the
GI tract
38
Alterations in absorption can be managed by
separating the times of administration
39
Drugs are “bound” to....in the blood during transportation
proteins
40
If a drug is 90% bound to a protein, then
10% of the drug is | providing the physiologic effect.
41
Neuromuscular Blockers
Used during anesthesia and surgery to relax muscle groups (Prevents laryngeal spasms)
42
what medication “paralyzes” the muscles, including the diaphragm? but does not take pain away?
neuromuscular blockers
43
Nurse needs to monitor for adverse effects up to...(neuromuscular blockers)
48 hours
44
Medications that potentiate the affects of Neuromuscular Blockers
Aminoglycosides and Tetracyclines
45
Aminoglycosides
The “micin group”, gentamicin, tobramycin, | streptomycin, neomycin.
46
Tetracyclines
The “cycline group” tetracycline, doxycycline, | minocycline, tigecycline
47
early signs of respiratory depression
Restlessness, Anxiety, Lethargy, Decreased Alertness, and Headache
48
late signs of respiratory depression
Use of abdominal, intercostal, or neck muscles, Flaring of nostrils, Shallow, rapid respirations, and Cyanosis
49
Skeletal Muscle Relaxants
Used to treat low back pain and spastic muscle | conditions
50
Spasticity
Muscle hypertonicity and involuntary jerks; stiff, awkward movements; complication of multiple sclerosis, cerebral palsy
51
Muscle spasms
Sudden alternating contractions and relaxations or sustained contractions of muscles
