ATI Capstone Pharmacology Assessment Questions
Question 1 of 5
A patient is receiving an IV infusion of heparin and was started on warfarin therapy the night
Correct Answer: D
Rationale: The correct statement is that the heparin provides anticoagulation until therapeutic levels of warfarin are reached. Heparin and warfarin are both anticoagulants but work in different ways. Heparin acts quickly to prevent blood clot formation while warfarin takes several days to reach its full effect. Therefore, heparin is often used initially to provide immediate anticoagulation while waiting for the warfarin to reach therapeutic levels. This dual therapy is common in clinical practice to ensure continuous anticoagulation.
Question 2 of 5
The nurse notes in the patient™s medication orders that the patient will be taking ibutilide (Corvert). Based on this finding, the nurse interprets that the patient has which disorder?
Correct Answer: B
Rationale: Ibutilide (Corvert) is a medication commonly used to treat atrial fibrillation, a type of irregular heart rhythm that originates in the heart's upper chambers (atria). It works by restoring normal heart rhythm in patients with atrial fibrillation. Therefore, the nurse notes the use of ibutilide in the patient's medication orders, indicating that the patient has atrial fibrillation.
Question 3 of 5
The nurse observes a short period of asystole on the cardiac monitor that resolves spontaneously immediately after administering adenosine IV to a patient who was experiencing paroxysmal supraventricular tachycardia. Which initial action is the most appropriate for the nurse?
Correct Answer: D
Rationale: Adenosine is used to treat paroxysmal supraventricular tachycardia (PSVT) by temporarily blocking AV node conduction, which can cause a brief period of asystole. This is an expected effect and typically resolves spontaneously. The nurse should closely monitor the patient and the cardiac monitor for the return of a normal rhythm. Calling a code (A), preparing epinephrine and atropine (B), or initiating CPR (C) is unnecessary unless the asystole persists or the patient becomes unstable.
Question 4 of 5
A patient is receiving an IV infusion of heparin and was started on warfarin therapy the night
Correct Answer: D
Rationale: The correct statement is that the heparin provides anticoagulation until therapeutic levels of warfarin are reached. Heparin and warfarin are both anticoagulants but work in different ways. Heparin acts quickly to prevent blood clot formation while warfarin takes several days to reach its full effect. Therefore, heparin is often used initially to provide immediate anticoagulation while waiting for the warfarin to reach therapeutic levels. This dual therapy is common in clinical practice to ensure continuous anticoagulation.
Question 5 of 5
A patient in the outpatient oncology clinic complains of fatigue after receiving chemotherapy. Which initial nursing intervention will be most appropriate?
Correct Answer: A
Rationale: Fatigue is a common side effect of chemotherapy and can be caused by various factors, including anemia, poor nutrition, sleep disturbances, or psychological stress. The nurse's first step should be to assess for underlying causes of fatigue, such as trouble sleeping, anemia, or depression. Once the cause is identified, appropriate interventions can be implemented, such as dietary changes, sleep hygiene strategies, or treatment for anemia. Encouraging excessive daytime sleep or strenuous exercise without assessment may worsen fatigue or lead to other complications.
