Cardiovascular Drugs Quiz Questions
Question 1 of 5
A patient is being changed from an injectable anticoagulant to an oral anticoagulant. Which anticoagulant does the nurse realize is administered orally?
Correct Answer: B
Rationale: Rationale: 1. Warfarin is administered orally, making it suitable for transitioning from an injectable anticoagulant. 2. Enoxaparin, Bivalirudin, and Dalteparin are injectable anticoagulants, not suitable for oral administration. Summary: Warfarin is the correct choice as it is the only oral anticoagulant among the options. Enoxaparin, Bivalirudin, and Dalteparin are injectable anticoagulants, not suitable for oral administration.
Question 2 of 5
A patient tells a nurse, “My doctor thinks my problem may lie with the neurotransmitters in my brain. Does that mean I have a serious problem?” How should the nurse reply to the patient’s question about the seriousness of the problem?
Correct Answer: A
Rationale: The correct answer is A because it acknowledges the patient's concern and invites further discussion to clarify the doctor's explanation. By exploring what the doctor has told the patient, the nurse can provide accurate information and address any misconceptions, helping the patient understand the situation better. Choice B jumps to conclusions about mental disorders without assessing the patient's actual situation. Choice C oversimplifies the treatment of neurotransmitter issues, which may vary in severity. Choice D assumes the patient's perception without addressing the underlying concerns. Overall, choice A promotes open communication and patient-centered care.
Question 3 of 5
When assessing patients in the preoperative area, the nurse knows that which patient is at a higher risk for an altered response to anesthesia?
Correct Answer: D
Rationale: The correct answer is D, the 78-year-old patient who is to have gallbladder removal. Older adults have a higher risk of altered response to anesthesia due to age-related changes in organ function, decreased metabolism, and increased sensitivity to medications. The other choices are less likely to have altered responses: A is young and healthy, B has stopped smoking which can reduce anesthesia risks, and C is a young patient with a routine procedure. Overall, age and complexity of the surgical procedure are key factors in determining the risk of altered response to anesthesia.
Question 4 of 5
A patient with primary hypertension is prescribed drug therapy for the first time. The patient asks how long drug therapy will be needed. Which answer by the nurse is the correct response?
Correct Answer: D
Rationale: Correct Answer: D Rationale: 1. Primary hypertension is a chronic condition. 2. Drug therapy for primary hypertension aims to control blood pressure long-term. 3. Lifestyle changes may help but often medication is needed. 4. Discontinuing medication can lead to uncontrolled hypertension. 5. Therefore, therapy for high blood pressure is usually lifelong. Summary: A: Incorrect, as 3 months is too short for chronic hypertension management. B: Incorrect, as a year may not be sufficient for long-term control. C: Incorrect, as symptom disappearance doesn't indicate resolved hypertension. D: Correct, as lifelong therapy is often necessary for primary hypertension.
Question 5 of 5
A patient has had recent prosthetic heart valve surgery and is receiving anticoagulant therapy. While monitoring the patient’s laboratory work, the nurse interprets that the patient’s international normalized ratio (INR) level of 2.5 indicates that
Correct Answer: B
Rationale: The correct answer is B: the patient’s warfarin dose is at therapeutic levels. An INR level of 2.5 is within the target range for patients on anticoagulant therapy, indicating that the warfarin dose is effective in preventing clot formation. A: Incorrect. An INR of 2.5 is considered therapeutic, so the patient is receiving enough warfarin. C: Incorrect. INR does not reflect heparin levels, so the intravenous heparin dose cannot be determined from this value. D: Incorrect. Similar to choice C, INR does not reflect heparin levels, so the status of the intravenous heparin dose cannot be determined.
