Exam1 Pharm: REV Flashcards
Acebutolol HCl (Sectral), a beta blocker, has negative chronotropic effects, what are they?
could cause symptomatic bradycardia and/or heart block
Cholinergic effects mimic which nervous system
parasympathetic (rest & digest)
The nurse is reviewing a patient’s list of medications with the patient. The nurse understands that the older adul’s slower absorption of oral meds is primarily because of…
increased pH of gastric secretions
Detrol
- overactive bladder
Decreased albumin level is expected in
- Elderly
- Newborns
- Liver Disease
- Manourished.
Drug movement from the blood to the interstitial space of tissues and from there into the cells.
Distribution
Which physiologic change that normally occurs in the older adult has implications for the nurse assessing drug response?
Drug half life is lengthened (shorter half life is better)
Which drug can be taken orally, noncat or cat?
Noncatecholamine
An example of this category drug would be accutane.
Category X
has an antagonistic effect with warfarin and will inhibit its effects.
Vitamin K
How is cardiac output measured?
- heart rate,
- blood pressure
- urine output
Psychological benefit of a drug despite no chemical drug effect
Placebo Effect
The nurse assesses a patient receiving an adrenergic (sympathomimetic) agent. Which finding will be of greatest concern to the nurse?
Weak peripheral pulses and decreased heart rate
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/Parasympathetic Actions
- Salivation
- Broncho Constriction
- GI peristalsis
- Pupil Constriction
Cholinergic Neurotransmitter
Acetycholine
Schedule III Drug
moderate or low physical dependence.
Drug that creates a response
Agonist
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
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
Which symptom presenting in an older adult would cause the nurse to suspect drug toxicity?
Confusion
Movement of the drug and their metabolites out of the body.
Excretion
Hypertension Treatment ABCD
- Ace inhibitor
- Beta Blockers
- Calcium channel Blockers
- Diuretics
Pharmacokinetics Includes These 4 Things
- Distribution
- Excretion
- Metabolism
- Absorption
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
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
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
If an acid is exposed to an alkaline environment what happens
it becomes ionized
A decrease in the responsiveness of the drug over the course of therapy.
Tolerance
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
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.
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
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
Which is a priority nursing diagnosis for a patient receiving an anticholinergic (parasympatholytic) medication?
Impaired gas exchange related to thickened respiratory secretions
If a patient has renal disease what happens to drug excretion
slowed or impaired. Drug accumulation
Hypertension Treatment
ABCD
- Ace inhibitors/ARBs
