Intro to Pharmacology ATI Quizlet Questions
Question 1 of 5
The nurse is reviewing discharge teaching for a patient who will be taking digoxin (Lanoxin) therapy. The nurse will teach the patient to avoid which foods when taking the digoxin?
Correct Answer: A
Rationale: Consuming high amounts of foods rich in potassium, such as leafy green vegetables, can potentially decrease the effectiveness of digoxin. Digoxin works by helping the heart beat more strongly and regularly, but too much potassium in the body can interfere with its action.
Therefore, patients taking digoxin are usually advised to avoid consuming excessive amounts of foods high in potassium, such as leafy green vegetables. It is recommended for patients on digoxin therapy to maintain a consistent level of potassium in their diet and follow their healthcare provider's guidance on dietary restrictions.
Question 2 of 5
Absorption, distribution, metabolism and excretion is the study of herdrugs':
Correct Answer: B
Rationale: Pharmacokinetics is the study of how drugs are absorbed, distributed, metabolized, and excreted by the body. These processes determine the concentration of a drug at its site of action and contribute to understanding the drug's effectiveness and potential side effects.
Therefore, absorption, distribution, metabolism, and excretion are key components of pharmacokinetics. Pharmacodynamics (
Choice
A) refers to the study of the physiological effects of drugs and their mechanisms of action, which is different from the processes involved in drug movement through the body. Therapeutic action (
Choice
C) refers to the desired effects of a drug in treating a specific condition, rather than the processes involved in drug processing in the body. Pharmaceutical preparation (
Choice
D) is related to the formulation and development of drugs before their administration, not to the processes within the body.
Toxic effect (
Choice E) refers to the harmful effects of drugs, which can result from various factors including pharmacokin
Question 3 of 5
A patient is admitted to the hospital with multidrug-resistant urinary tract infection. Laboratory tests show Pseudomonas aeruginosa. Colistimethate sodium is ordered by intramuscular injection. The nurse understands that which of the following is the purpose for this drug?
Correct Answer: B
Rationale: Colistimethate sodium is a polymyxin antibiotic used to treat multidrug-resistant Gram-negative infections, including Pseudomonas aeruginosa. It is not safe for patients with renal impairments and does not prevent antibiotic resistance. Its primary purpose is to treat infections caused by resistant Gram-negative bacteria.
Question 4 of 5
A patient is in the emergency department with new-onset atrial fibrillation. Which order for digoxin would most likely have the fastest therapeutic effect?
Correct Answer: D
Rationale: In a patient with new-onset atrial fibrillation who requires rapid initiation of digoxin therapy, the fastest therapeutic effect would be achieved by administering the loading dose intravenously. Option D (Digoxin 1 mg IV push now; then 0.25 mg IV daily) includes an initial IV loading dose of 1 mg, followed by a maintenance dose of 0.25 mg IV daily. IV administration allows for quicker absorption and onset of action compared to oral administration. This loading dose increases the digoxin concentration in the bloodstream more rapidly, leading to a quicker therapeutic effect. Subsequent maintenance doses can then be given orally for long-term management.
Question 5 of 5
A patient is being educated on taking levothyroxine, a drug used to balance thyroid activity. What should you include in their education?
Correct Answer: B
Rationale: It is important to educate the patient to take levothyroxine at the same time every day, preferably in the morning on an empty stomach. Consistency in timing helps to maintain stable levels of the medication in the body and optimize its effectiveness in balancing thyroid activity. This medication should not be taken with food, vitamins, or other medications that can interfere with its absorption. Regular thyroid tests are necessary to monitor the effectiveness of the medication and adjust the dosage as needed. If a patient has experienced a recent myocardial infarction or heart attack, it is crucial to consult with healthcare professionals before starting or continuing levothyroxine, as it can have implications on cardiovascular health. It is never advisable for patients to avoid consulting their healthcare professionals if they experience any adverse effects or have concerns about their medication.
