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, known as "grouped beating." In Type 1 AV block, there is a progressive lengthening of the PR interval until a QRS complex is dropped. This is consistent with the description provided in the question. A: Third degree AV block is characterized by complete dissociation between the atria and ventricles, resulting in an atrial rate that is typically faster than the ventricular rate. This is not the case in the scenario described. B: Type 2 second degree AV block is characterized by intermittent failure of conduction of P waves to the ventricles, resulting in dropped QRS complexes. This is not consistent with the description provided. D: Junctional escape rhythm is characterized by an escape rhythm originating from the AV junction, resulting in a heart rate of 40-60 bpm. This is not the rhythm described
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: Heart rate increases from 66 to 98 beats/min. After an AMI, an increase in heart rate during ambulation may indicate cardiac strain or insufficient oxygen delivery. This suggests the exercise level should be decreased to prevent further cardiac stress. A: O saturation drops from 99% to 95% - This decrease in oxygen saturation can indicate impaired gas exchange but is not a direct indicator of cardiac strain during exercise. C: Respiratory rate goes from 14 to 20 breaths/min - An increase in respiratory rate may suggest increased effort but does not specifically indicate cardiac strain. D: Blood pressure (BP) changes from 118/60 to 126/68 mm Hg - This change in BP is within a normal range and does not directly signal a need to decrease 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 important to communicate because it could indicate a serious side effect called rhabdomyolysis, a rare but serious condition where muscle breakdown releases toxic substances into the bloodstream. This can lead to kidney damage and other complications. B: Dizziness with rapid position changes is a common side effect of niacin and usually not as concerning as muscle aches. C: Nausea when taking the drugs before meals is a common side effect of niacin and can often be managed by taking the medication with food. D: Flushing and pruritus after taking the drugs are common side effects of niacin and not as serious as muscle aches.
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) should be completed first. This is because an ECG provides immediate information on the patient's cardiac status and can help in diagnosing conditions like a heart attack. This test is crucial in quickly determining the presence of significant cardiac abnormalities. Chest x-ray (A) may provide information on lung conditions but does not directly assess the heart. Troponin level (B) is important for diagnosing a heart attack but takes time to process. Insertion of a peripheral IV (D) is necessary for treatment but is not as urgent as obtaining the ECG results.
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 impaired circulation or complications such as arterial occlusion. This intervention helps to detect early warning signs and prevent potential complications. A: Helping the client ambulate to the bathroom is important for mobility but not the most critical intervention post-cardiac catheterization. B: Fluid restriction is not typically indicated after cardiac catheterization unless specifically ordered by the healthcare provider. D: Inserting an indwelling urinary catheter is not necessary unless there is a specific indication such as urinary retention. Monitoring peripheral pulses takes priority for assessing circulation status.
