Question 1 of 5
A client asks the nurse to explain the difference between stable and unstable angina. What is the best response by the nurse?
Correct Answer: A
Rationale: The correct answer is A because stable angina is characterized by predictable patterns of chest pain related to exertion or stress, while unstable angina involves a change in the frequency, intensity, or duration of angina episodes, often occurring at rest.
Choice B is incorrect because it wrongly states that unstable angina is predictable.
Choices C and D are incorrect because they inaccurately attribute stable angina to coronary artery spasms, which is not the typical cause.
Question 2 of 5
The nurse is describing angina to a family member of a client recently diagnosed with the condition. Which characterization of angina is the most appropriate?
Correct Answer: B
Rationale: The correct answer is B: Chest pain on physical exertion or emotional stress. Angina is characterized by chest pain or discomfort caused by reduced blood flow to the heart muscle. This is typically triggered by physical exertion or emotional stress, as the heart requires more oxygen during these times. Slow heart rate and difficulty standing (
A), sudden weakness with severe headache (
C), and difficulty breathing and increased temperature (
D) are not characteristic of angina. Angina is specifically related to chest pain and is not associated with these symptoms.
Question 3 of 5
An older patient has a prescription for sertraline (Zoloft) 25 mg/day, P O. to be taken for 1 week and then increased to 50 mg/day the second week. The pharmacy gives the patient 50-mg tablets. How many tablets will the patient take per day during the first week?
Correct Answer: D
Rationale: The correct answer is D: Half tablet. During the first week, the patient is prescribed 25 mg/day of sertraline. Since the pharmacy provides 50-mg tablets, the patient needs to take half of the tablet to achieve the prescribed dosage. This would be equivalent to 25 mg, as required. Taking one and one-half tablets (
A) would exceed the prescribed dosage, one-quarter of the tablet (
B) would not provide enough medication, and taking one tablet (
C) would also exceed the prescribed dosage.
Therefore, the correct answer is half tablet (
D) to achieve the prescribed 25 mg/day dosage during the first week.
Question 4 of 5
Which of the following drug classes does isosorbide (Isordil) belong to?
Correct Answer: B
Rationale: Isosorbide belongs to the class of nitrates, which are vasodilators used to treat angina by dilating blood vessels and increasing blood flow. It works by relaxing smooth muscles in blood vessels, reducing the heart's workload and improving oxygen supply to the heart. Beta blockers (
A) slow heart rate, calcium channel blockers (
C) relax blood vessels by blocking calcium entry, and glycoprotein lib/lla receptor antagonists (
D) prevent platelet aggregation, all different mechanisms than nitrates.
Question 5 of 5
The nurse has just completed medication teaching regarding medications used to treat high cholesterol. Which statement made by the client indicates a need for further teaching?
Correct Answer: A
Rationale:
Correct
Answer: A
Rationale:
Choice A indicates a misconception that taking medications alone can negate the need for dietary restrictions in managing high cholesterol. This statement shows a lack of understanding about the importance of lifestyle modifications in addition to medication therapy. Following a healthy diet is crucial in controlling cholesterol levels. Thus, further teaching is needed to emphasize the significance of dietary changes.
Choices B, C, and D are all correct statements that demonstrate understanding of the medication regimen and necessary actions to take when managing high cholesterol.
