Pharmacology Exam #2
A 7-year-old child contracts a urinary tract infection. A sulfonamide preparation is prescribed. What is the priority nursing responsibility when the nurse is administering this drug?
Administering the drug at the prescribed times
A client's serum lithium level is 0.2 mEq/L (0.2 mmol/L). What is the nurse's interpretation of this finding?
Below therapeutic range
A client on the psychiatric unit who is receiving high-dosage risperidone is exhibiting tremors of the hands. What will be the nurse's first intervention?
Contacting the primary healthcare provider
A client with arthritis is taking large doses of aspirin. What symptom does the nurse include when teaching the client about the clinical manifestations of aspirin toxicity?
Disturbances in hearing
What are the pharmacokinetic reasons for drug sensitivity in infants? Select all that apply.
Drug absorption Renal drug excretion Protein binding of drugs Hepatic drug metabolism
A nurse is teaching the parents of a child with attention deficit hyperactivity disorder. What does the nurse include as the most frequently prescribed medication for this disorder?
Methylphenidate
What are the major reasons that the pediatric population is more sensitive to drugs when compared to adults? Select all that apply.
Protein binding Blood-brain barrier Renal drug excretion Hepatic drug metabolism
A head nurse teaches a group of nursing students about the physiologic changes that may occur during pregnancy. What statement by a nursing student indicates effective teaching?
Renal blood flow is doubled during the third trimester, which increases the glomerular filtration rate.
A client is diagnosed with Parkinson disease and receives a prescription for levodopa therapy. What does the nurse identify as the drug's mechanism of action?
Restores the dopamine levels in the brain
A client receiving morphine is being monitored by the nurse for adverse effects of the drug. Which clinical findings warrant immediate follow up by the nurse? Select all that apply.
Sedation Bradycardia Slow respirations
A client is responding within 5 minutes of receiving naloxone to combat respiratory depression from an overdose of heroin. Why will a nurse continue to closely monitor this client's status?
Symptoms of the heroin overdose may return after the naloxone is metabolized.
A client with depression is to be given fluoxetine. What precaution will the nurse consider when initiating treatment with this drug?
The blood level may not be sufficient to cause noticeable improvement for 2 to 4 weeks.
The protein binding capacity of drugs in infants is low. Which is an implication of this physiologic process?
The free levels of a drug will increase.
What is the planned effect of naloxone when it is administered for a heroin overdose?
To compete with opioids for occupancy of opioid receptors
Which pharmacokinetic condition of a drug may result in a high intensity and long duration of response?
When absorption is rapid but elimination is delayed
A nurse is teaching an older adult client about managing chronic pain with acetaminophen. Which client statement indicates that the teaching is effective?
"I have to be careful about which over-the-counter cold preparations I take when I have a cold."
