ATI Pharmacology Practice A 2023 Questions
Question 1 of 5
The patient receives a drug that is excreted in the bile. What will the best nursing assessment of the effect of this drug on the patient include?
Correct Answer: A
Rationale: Biliary excretion (e.g., rifampin) can prolong a drug's action via enterohepatic recycling-reabsorption from the gut extends duration, a key assessment point. Side effects don't inherently increase or decrease-dose and metabolism matter. Reduced effect assumes loss, not recycling. Prolonged action reflects pharmacokinetics, guiding monitoring for efficacy and toxicity.
Question 2 of 5
A mother brings her unconscious 14-year-old son to the emergency department. He was found in his bedroom by his mother appearing agitated and sweaty. He complains of a feeling of ants crawling under his skin and a dry mouth. The mother suspects that he has been abusing his brother's prescription ADHD medicine, showing an empty pill bottle. What should he be given now?
Correct Answer: C
Rationale: ADHD stimulant (e.g., amphetamine) overdose (formication, dry mouth) lacks a specific antidote, but flumazenil -is listed, likely a typo for a benzo to calm agitation. Ammonium chloride , epinephrine , pilocarpine , and theophylline (E) don't fit. Benzos would address symptoms.
Question 3 of 5
A neighbor tells nurse Maureen he has to have surgery and is reluctant to have any blood product transfusions because of a fear of contracting an infection. He asks the nurse what are his options. The nurse teaches the person that the safest blood product is:
Correct Answer: C
Rationale: An autologous blood product is the safest option for the neighbor who is reluctant to have blood transfusions due to a fear of contracting an infection. Autologous blood is blood that is donated by the patient themselves prior to surgery. This type of blood product eliminates the risk of transmitting infections from other donors, as the blood comes from the patient's own body. It is considered the safest option for those concerned about infection transmission during blood transfusions.
Question 4 of 5
What is the Therapeutic E昀昀ects of Lithium?
Correct Answer: A
Rationale: Lithium is primarily used as a mood stabilizer in the treatment of bipolar disorder. One of the therapeutic effects of lithium is its ability to prevent or decrease the incidence of acute manic episodes in individuals with bipolar disorder. By regulating neurotransmitter levels and affecting intracellular signaling pathways, lithium helps to stabilize mood and prevent the extreme highs of mania. It does not have a direct effect on blood glucose maintenance, control of hyperglycemia, or seizure activity, which are unrelated to its primary mechanism of action in managing mood disorders.
Question 5 of 5
A 31-year-old woman is planning to take a 7-day cruise to the Caribbean islands. She has never been on a ship before and fears developing motion sickness. She purchases scopolamine transdermal patch. When is the best time for her to place the patch to maximize drug efficacy?
Correct Answer: D
Rationale: Scopolamine prevents motion sickness via anticholinergic action. Applying prior to symptoms -ensures prophylaxis. After nausea (A, B) or vomiting is too late. Memory loss is a side effect, not timing. Preemptive use maximizes efficacy for her cruise.
