ATI LPN
Questions for Cardiovascular Assessment Questions
Question 1 of 5
All of the following will increase heart rate except:
Correct Answer: D
Rationale: Cold receptor stimulation typically slows down the heart rate rather than increasing it.
Question 2 of 5
Which diagnostic test will be most useful to the nurse in determining whether a patient admitted with acute shortness of breath has heart failure?
Correct Answer: C
Rationale: B-type natriuretic peptide (BNP) is secreted when ventricular pressures increase, as they do with heart failure. Elevated BNP indicates a probable or very probable diagnosis of heart failure. A 12-lead electrocardiogram, arterial blood gases, and troponin may also be used in determining the causes or effects of heart failure but are not as clearly diagnostic of heart failure as BNP.
Question 3 of 5
A Level Regular aerobic exercise results in significant benefits to the heart and vascular system. What are these benefits and how do they contribute to a 'healthier lifestyle'?
Correct Answer: D
Rationale: Exercise enhances cardiovascular health, reducing risks of diseases and improving overall well-being.
Question 4 of 5
Rough part of left and right atrium derived from?
Correct Answer: A
Rationale: The rough parts of both atria (pectinate muscles) derive from the common primordial atrium in embryonic development.
Question 5 of 5
Which of the following decreases the risk of ventricular fibrillation?
Correct Answer: B
Rationale: An increased refractory period prevents re-entry circuits, reducing the risk of ventricular fibrillation.
