Exam1 Pharm: REV Flashcards
Decreased albumin level is expected in
- Elderly
- Newborns
- Liver Disease
- Manourished.
An example of this category drug would be accutane.
Category X
Psychological benefit of a drug despite no chemical drug effect
Placebo Effect
Atropine
- pre-op med to decrease salivary secretions and maintain heart rate
- increase heart rate
Adverse reactions of Atropine
- asal congestion
- tachycardia
- hypotension
- pupillary dilation
- abdominal distention
- palpitations.
Scopolamine
decreased Gi Motility, Motion sickness
Cholinergic Neurotransmitter
Acetycholine
Schedule III Drug
moderate or low physical dependence.
If a drug becomes ionized what will happen?
it will not pass a lipid soluble
Atropine Toxicity
MAd as a hatter (confusion), dry as the street, hot as the summer, red as a beet.
If a patient has diabetes, what would the best beta blocker be for that patient?
Lopressor, Tenormin
The nurse takes all precautions in order to ensure that the pediatric patient will receive a drug dosage that is accurate based on body surface area. To which step of the nursing process does this action most closely correspond?
planning
Which symptom presenting in an older adult would cause the nurse to suspect drug toxicity?
Confusion
Hypertension Treatment ABCD
- Ace inhibitor
- Beta Blockers
- Calcium channel Blockers
- Diuretics
If an acid is exposed to an alkaline environment what happens
it becomes ionized
What are the reasons for the lack of research done for Pediatric Pharmacology?
- difficult to get large enough study sample
- Diseases occur in small numbers
An estimate of the margin of safety of a drug.
Therapeutic Range
A nurse is monitoring a patient receiving atropine. Which finding requires nursing action?
Blood pressure of 90/40 mm Hg
A decrease in the responsiveness of the drug over the course of therapy.
Tolerance
Absorption of Medications:
- Lipid soluble medications absorb easily through the GI membrane because the GI membrane is composed mostly of lipids.
- Nonionized substances pass easily through the GI membrane.
- Water soluble medications require a carrier to pass through the GI membrane (active absorption).
A 2 year old patient is to receive a topical medication. The nurse considers which factro when administering this medication?
thinner skin in children allows for rapid absorption.
The nurse is administering medication to an older adult. The nurse anticipates that this patient’s renal system will have which effect on the medication?
the medication will be excreted slower
an antispasmodic cholinergic blocker used to decrease GI motility in patients with functional GI disorders such as irritable bowel syndrome.
Dicyclomine (Bentyl)
Atrovent
used for asthma COPD, and rhinitis
BBB
- Blood Brain Barrier
- semipermeable in the CNS
- protects brain from foreign substances
- highly lipid drugs cross
- water soluble drugs do not make it across
A disease characterized by spasm of the arteries in the extremities, especially the fingers. It is typically brought on by constant cold or vibration, and leads to pallor, pain, numbness, and in severe cases, gangrene.
Raynaud’s Disease
Hypertension Nursing Care
- Daily Weight
- Intake & Output
- Urine Output
- Response of BP
- Electrolytes
- TAke pulses
- Ischemic Episodes
- Compications (4C’s)
“protein binding” refers to…?
- “free” drug (drug not bound to protein) that will be able to create a pharmacologic response
- When two drugs are given together that are both “highly protein-bound” drugs, the pateint is at greater risk of drug accumulation (drug toxicity).
- Ibuprofen is a 98% protein bound drug. This means that 98% of the drug is bound to protein (albumin), and only 2% of the drug is “free”.
What organ metabolizes the lipid soluble drug to trasnform it to a water soluble drug for renal excretion
Liver
Alpha 1 Agonist Used for…
- Bradycardia
- Low BP
- GI
Pharmacokinetics Includes These 4 Things
- Distribution
- Excretion
- Metabolism
- Absorption
If a patient has renal disease what happens to drug excretion
slowed or impaired. Drug accumulation
Which is a priority nursing diagnosis for a patient receiving an anticholinergic (parasympatholytic) medication?
Impaired gas exchange related to thickened respiratory secretions
Hypertension Treatment
ABCD
- Ace inhibitors/ARBs
- Beta Blockers
- Calcium channel blockers
- Diuretics
Movement of the drug and their metabolites out of the body.
Excretion
Knowing that the albumin in neonates and infants has a lower binding capacity for medications, the nurse anticipates that the health care provider will order which adjustment to minimize the risk of toxicity?
A decrease in the dosage of drug given
The nurse is caring for a patient who is prescribed propranolol (Inderal). Which assessment finding will reveal if the medication is having a therapeutic effect?
The patient’s blood pressure is 130/75 mm Hg
During this phase a drug in solid form must be disintegrated to dissolve and be absorbed
pharmacoceutic
Drug that creates a response
Agonist
Cholinergic Agonist Effects
Sludge BAM
- Salivation/Sweating/Secretions
- Lacrimation
- Urination
- Defecation
- GI Upset
- Emesis
- Bradycardia
- Ab Cramps
- Miosis
A patient with poor renal function (low glomerular filtration) will have what type of creatinine?
- elevated blood creatinine levels
- low urine creatinine levels.
- drug dosages typically need to be decreased.
Adverse drug reaction from excessive dosing of the drug
Toxic Effect
Adrenergic Neurotransmitter
norepinephrine, epinephrine
Abrupt withdrawal of a beta blocker can cause
rebound hypertension
Cholinergic/Parasympathetic Actions
- Salivation
- Broncho Constriction
- GI peristalsis
- Pupil Constriction
The term used for a drug that is approved for one thing but used for something completely different?
Off Label
Predictable secondary effect of the drug. Can be desirable or undesirable
Side effect
beta blockers are used to treat:
- Angina pectoris
- Congestive heart failure (CHF)
- Hypertension
