Intro to Pharmacology ATI Quizlet Questions
Question 1 of 9
The patient takes labetalol and is scheduled for surgery. The anesthesiologist plans to use halothane as one of the anesthetic agents. The nurse consults with the anesthesiologist to ensure awareness the patient’s medication history knowing that the combination of labetalol and halothane will have what effect?
Correct Answer: A
Rationale: There is increased risk of excessive hypotension if any of these drugs is combined with volatile liquid general anesthetics such as enflurane, halothane, or isoflurane. The effectiveness of diabetic agents is increased, leading to hypoglycemia when such agents are used with these drugs. Carvedilol has been associated with potentially dangerous conduction system disturbances when combined with verapamil or diltiazem. Vomiting is not associated with this combination of drugs. The nurse should communicate the patient’s medication history to the anesthesiologist to ensure safe administration of anesthesia.
Question 2 of 9
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 3 of 9
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.
Question 4 of 9
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 9
What nursing interventions should you do when a patient is on Albuterol (select all that apply)
Correct Answer: A
Rationale: A. Assess lung sounds, Pulse, and Blood pressure before administering: Before administering Albuterol, it is crucial to assess the patient's lung sounds, pulse, and blood pressure as baseline data. This helps in monitoring the effects of Albuterol on the respiratory and cardiovascular systems.
Question 6 of 9
A patient is taking Digoxin to slow his heart rate down. The nurse suggests that he take his oral medication:
Correct Answer: A
Rationale: It is recommended for the patient to take Digoxin in the morning when awakening. This is because Digoxin has a long half-life which means it stays in the body for a long period of time. By taking it in the morning, the patient can benefit from its effects throughout the day, including its ability to slow down the heart rate and improve heart function. Additionally, taking it in the morning helps to reduce the risk of potential interactions with other medications or food consumed later in the day.
Question 7 of 9
Which route should lithium be administered by?
Correct Answer: A
Rationale: Lithium is typically administered orally (PO) for long-term treatment of bipolar disorder. However, in emergency situations or cases of lithium toxicity where rapid control of symptoms is required, lithium can be administered via the intravenous (IV) route for faster absorption and effectiveness. IV administration allows for quick delivery of the medication directly into the bloodstream to achieve therapeutic levels promptly. It is essential to closely monitor lithium levels and kidney function when administering it intravenously to prevent potential complications.
Question 8 of 9
A patient is taking ibuprofen. The nurse understands that COX-1 and COX-2 inhibitors are different in that ibuprofen is more likely than celecoxib to cause which adverse effect?
Correct Answer: C
Rationale: Ibuprofen is a non-selective COX inhibitor, meaning it inhibits both COX-1 and COX-2 enzymes. COX-1 is responsible for maintaining the protective lining of the stomach, and its inhibition can lead to gastrointestinal adverse effects such as peptic ulcer disease. Celecoxib, on the other hand, is a selective COX-2 inhibitor, which primarily targets inflammation and pain without significantly affecting the stomach lining. Therefore, ibuprofen is more likely to cause peptic ulcer disease compared to celecoxib. This distinction is crucial for nurses to understand when managing patients on these medications, as it impacts patient monitoring and education.
Question 9 of 9
A patient is taking Digoxin to slow his heart rate down. The nurse suggests that he take his oral medication:
Correct Answer: A
Rationale: The nurse suggests that the patient takes his Digoxin medication when awakening because it is best absorbed when taken on an empty stomach. Taking Digoxin with meals can decrease its absorption, reducing its effectiveness. Therefore, to ensure optimal absorption and effectiveness of Digoxin in slowing down the heart rate, it is recommended to take it when awakening on an empty stomach.
