Cardiovascular Drugs Quiz Questions
Question 1 of 5
Which of the client’s neurotransmitters should a nurse expect to be elevated?
Correct Answer: B
Rationale: The correct answer is B: Dopamine. Dopamine is a neurotransmitter associated with pleasure, reward, and motivation. Elevated levels of dopamine can be seen in conditions like schizophrenia and mania. Serotonin is more related to mood regulation, GABA to inhibitory neurotransmission, and histamine to allergic responses, making them less likely to be elevated in this context.
Question 2 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 3 of 5
The laboratory report for a patient taking clozapine (Clozaril) shows a white blood cell count of 3000 mm3. Select the nurse’s best action.
Correct Answer: A
Rationale: The correct answer is A: Report these results to the health care provider immediately. A low white blood cell count (3000 mm3) in a patient taking clozapine (Clozaril) could indicate a potentially serious condition called agranulocytosis, which is a severe decrease in white blood cells. This condition can increase the risk of infection and is a known side effect of clozapine. Reporting these results to the health care provider immediately is crucial for prompt evaluation and appropriate management, such as discontinuing the medication or adjusting the dosage. Summary of incorrect choices: B: Giving the next dose as prescribed is risky without addressing the low white blood cell count first. C: Giving aspirin and forcing fluids is unrelated to the low white blood cell count and could worsen the situation. D: Repeating the laboratory test may delay necessary intervention for the potentially serious condition of agranulocytosis.
Question 4 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 5 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.
