ATI Cardiovascular Test Bank Questions
Question 1 of 5
The client has a heart rate of 70, a slightly irregular rhythm and P waves that come in multiples. What is this rhythm called?
Correct Answer: C
Rationale: The correct answer is C: Type 1 second degree AV block. This rhythm is characterized by a slightly irregular rhythm and P waves that come in multiples, indicating a delay in the AV node conduction. In Type 1 second degree AV block, there is a progressive prolongation of the PR interval until a P wave is blocked, resulting in a skipped QRS complex. This matches the description given in the question. Choice A (Third degree AV block) is incorrect because in this condition, there is complete blockage of the electrical impulses between the atria and ventricles, resulting in an independent rhythm for both chambers. Choice B (Type 2 second degree AV block) is incorrect because in this condition, there is a consistent PR interval before a blocked P wave without progressive prolongation as seen in the question. Choice D (Junctional escape rhythm) is incorrect as it is characterized by a heart rate originating from the AV junction due to a failure of the SA node,
Question 2 of 5
After an acute myocardial infarction (AMI), a patient ambulates in the hospital hallway. When the nurse evaluates the patient’s response to the activity, which data would indicate that the exercise level should be decreased?
Correct Answer: B
Rationale: The correct answer is B because an increase in heart rate from 66 to 98 beats/min after ambulation post-AMI indicates potential cardiac stress. This elevation could signify inadequate cardiac output or compromised heart function, prompting the need to decrease exercise intensity to prevent further strain on the heart. Choices A, C, and D do not directly reflect cardiac function and are within normal ranges post-AMI, so they would not be immediate indicators for reducing exercise level.
Question 3 of 5
A patient who has recently started taking pravastatin (Pravachol) and niacin reports several symptoms to the nurse. Which information is most important to communicate to the health care provider?
Correct Answer: A
Rationale: The correct answer is A: Generalized muscle aches and pains. This is the most important information to communicate because it could indicate a serious side effect known as rhabdomyolysis, a rare but severe condition that can be caused by statins (like pravastatin) and niacin. Rhabdomyolysis is characterized by muscle breakdown that can lead to kidney damage. It is crucial to monitor and address this symptom promptly. Choice B (Dizziness with rapid position changes) may be related to orthostatic hypotension, a common side effect of some medications but is not as urgent as potential rhabdomyolysis. Choice C (Nausea when taking the drugs before meals) is a common side effect of niacin and may be managed by adjusting the timing of medication administration. Choice D (Flushing and pruritus after taking the drugs) is a common side effect of niacin known as flushing and is generally not considered as serious as
Question 4 of 5
A patient who has chest pain is admitted to the emergency department (ED), and all of the following are ordered. Which one should the nurse arrange to be completed first?
Correct Answer: C
Rationale: The correct answer is C: Electrocardiogram (ECG). This should be arranged first because it provides immediate information on the patient's cardiac status, helping to determine if the chest pain is due to a heart-related issue like a myocardial infarction. A quick ECG can identify any acute changes in the heart's electrical activity. This is crucial for prompt intervention and treatment. Summary of other choices: A: Chest x-ray - While important for assessing lung and chest abnormalities, it does not provide immediate information on the patient's cardiac status. B: Troponin level - Useful for detecting myocardial damage, but results may take time to be available. Not as immediate as an ECG. D: Insertion of a peripheral IV - Important for administering medications and fluids, but not a priority over assessing the cardiac status in a patient with chest pain.
Question 5 of 5
A client has just returned from cardiac catheterization. Which nursing intervention would be most appropriate?
Correct Answer: C
Rationale: The correct answer is C: Monitor peripheral pulses. After cardiac catheterization, monitoring peripheral pulses is crucial to assess for any signs of complications such as decreased blood flow or vascular compromise. This intervention helps in early detection of potential issues and ensures prompt intervention if needed. A: Helping the client ambulate to the bathroom may be appropriate but monitoring peripheral pulses takes priority for assessing immediate complications post-cardiac catheterization. B: Fluid restriction is not indicated unless specifically prescribed by the healthcare provider. It is not a standard nursing intervention post-cardiac catheterization. D: Inserting an indwelling urinary catheter is not a priority intervention after cardiac catheterization unless there are specific indications such as monitoring urine output closely. Monitoring peripheral pulses takes precedence in this scenario.
