ATI RN Pharmacology Online Practice 2023 A Questions
Question 1 of 5
The following oral drugs do not require absorption from the gut to exert a therapeutic effect:
Correct Answer: C
Rationale: Orlistat works within the gastrointestinal tract by inhibiting pancreatic lipase, reducing fat absorption directly without systemic absorption.
Question 2 of 5
Which is the only type of insulin that can be given IV?
Correct Answer: A
Rationale: Regular insulin is the only type of insulin that can be given intravenously (IV) due to its short onset of action. When administered IV, regular insulin can act quickly to control blood sugar levels in emergency situations such as diabetic ketoacidosis (DKA) or hyperglycemic crises. Other types of insulin, such as NPH, long-acting, or rapid-acting insulins, are not suitable for IV administration as they have different pharmacokinetic properties and are designed for subcutaneous use.
Question 3 of 5
A 24-year-old G1P0 woman arrives at the hospital in labor at 39 weeks gestation. She denies an epidural, stating her desire to give birth naturally. After 5 h of labor, the baby has begun its descent through the birth canal when the patient requests pain relief. Which of the following opioids would be best to administer?
Correct Answer: A
Rationale: Labor pain relief without epidural favors Butorphanol , a mixed opioid agonist-antagonist. It provides analgesia with less respiratory depression risk to the fetus than Codeine , Methadone , or Morphine (E). Dextromethorphan is a cough suppressant. Butorphanol's safety profile suits late labor, minimizing neonatal impact.
Question 4 of 5
While teaching a 76-year-old patient about the adverse effects of his medications, the nurse encourages him to keep a journal of the adverse effects he experiences. This intervention is important for the elderly patient because of which alterations in pharmacokinetics?
Correct Answer: C
Rationale: Elderly patients often experience decreased blood flow to the liver due to age-related changes, which can alter drug metabolism and increase the risk of adverse effects. Keeping a journal of adverse effects helps the patient and healthcare provider monitor and manage these effects effectively. Increased renal excretion, alkaline gastric pH, and reduced adipose tissue are less relevant to the need for monitoring adverse effects. Therefore, the nurse's intervention is most important due to altered liver metabolism in elderly patients.
Question 5 of 5
A 42-year-old man undergoes a neurologic evaluation because of episodes of apparent confusion. Over the past year, the man has experienced episodes during which he develops a blank look on his face and fails to respond to questions. Moreover, it appears to take several minutes before the man recovers from the episodes. Which one of the following best describes this type of seizure?
Correct Answer: B
Rationale: Focal complex partial seizures impair consciousness, causing confusion, unresponsiveness, and a blank stare, lasting minutes with slow recovery, as described. Simple partial seizures preserve awareness with focal symptoms. Tonic-clonic seizures feature convulsions. Absence seizures are brief (seconds) with rapid recovery. Myoclonic seizures involve jerks. The prolonged duration and impaired consciousness align with complex partial seizures' temporal lobe origin and EEG findings, distinguishing it here.
